Erin B
Stage 2 invasive ductal breast cancer
When Erin Bacon called to cancel her double mastectomy, doctors told her she was going to die. The 33-year-old American Airlines worker from Florida had been diagnosed with stage two breast cancer in February 2022 after she found a large lump behind her right nipple. By the time her surgery was scheduled, she had already been through seven months of grueling chemotherapy - which left her feeling constantly sick and struggling to breathe. But she said the treatment had 'barely shrunk' her three-inch tumor. The next step, doctors said, was to remove both breasts. But Bacon was completely against the idea of surgery. 'I just knew this wasn't the path I wanted to go down,' she told the Daily Mail. 'It's difficult for anyone to lose their breasts, but especially at 33 years old, when you're a little young, and you feel like you're in the prime of your life.' After canceling the appointment in September 2022, Bacon turned to alternative remedies she found on the internet, adopting a strict vegan diet and drinking herbal teas.

The 33-year-old American Airlines worker from Florida had been diagnosed with stage two breast cancer in February 2022 after she found a large lump behind her right nipple.
By the time her surgery was scheduled, she had already been through seven months of grueling chemotherapy - which left her feeling constantly sick and struggling to breathe. But she said the treatment had 'barely shrunk' her three-inch tumor.
The next step, doctors said, was to remove both breasts. But Bacon was completely against the idea of surgery.
'I just knew this wasn't the path I wanted to go down,' she told the Daily Mail. 'It's difficult for anyone to lose their breasts, but especially at 33 years old, when you're a little young, and you feel like you're in the prime of your life.'
After canceling the appointment in September 2022, Bacon turned to alternative remedies she found on the internet, adopting a strict vegan diet and drinking herbal teas.
For a while, she believed the remedies were working - there is some medical evidence that suggests slashing sugar consumption from a patient's diet can slow cancer growth. But after more than a year, her tumor began to grow again.
Desperate for a cure, but still not wanting surgery, Bacon found the Williams Cancer Institute based in California. She signed up for an experimental therapy they offer out of a satellite office in Cabo San Lucas, Mexico.
Erin Bacon (pictured), 33, was told by doctors she would die if she did not receive a double mastectomy. But after finding an experimental treatment, she is cancer-free and has kept her breasts
She said the procedure - which has not been approved in the US - saved her life (and her breasts)
.
Bacon told the Daily Mail that she had always led a healthy life, staying 'very active' with Pilates, weightlifting and cardio classes, and sticking to a nutritious diet.
She routinely checked her breasts for signs of cancer after her aunt and grandmother were diagnosed with the disease, which is how she discovered the lump. Both survived the cancer - her aunt received a lumpectomy and radiation, and her grandmother had a mastectomy and lived to be 94.
After visiting her doctor about the lump, Bacon was told she had stage two invasive ductal carcinoma, the most common form of breast cancer. It is behind 80 percent of cases and originates in the milk ducts of the breasts.
At stage two, about 93 percent of patients survive more than five years, and 35 percent undergo a mastectomy.
Her initial chemo treatment included infusions of three different drugs over the course of one four-hour session a week.
Among the drugs used was doxorubicin, also known as the 'red devil' because of its bright red color. The drug is used to treat several cancers, including of the breasts, lungs and ovaries. It works by interfering with the DNA in cancer cells and slowing their multiplication.
Bacon is pictured above at the Williams Cancer Institute while undergoing treatment. In this image, doctors are infusing immunotherapy drugs directly into her tumor.

Bacon said she initially recovered well from the infusions, but soon started to feel tired constantly, lost her taste and felt like she 'couldn't breathe' - doxorubicin can cause damage or injury to the heart muscle.
Even with the treatment, she told the Daily Mail her tumor shrank 'very little.'
She said that was when the double mastectomy came into play. She recalled being told it would eradicate the cancer before it spread to her healthy breast or elsewhere in the body.
Bacon initially agreed, but four days before her appointment, she cancelled the operation.
'My doctor, the surgeon, called me,' she recalled to the Daily Mail. 'And she's like screaming at me, "Are you sure you want to cancel?" And I'm like, "Yeah, I'm positive"...
'Blatantly, she said, "If you don't have a mastectomy, you're going to die."'
After her subsequent failed attempts to treat the cancer herself, Bacon frantically searched the internet for 'alternative breast cancer treatments' and eventually found the Institute.
Bacon (left) is pictured with Dr Jason Williams (right), who runs the Williams Cancer Institute and carried out her treatment
The center's approach treats cancer by targeting tumors directly to reveal them to the immune system, cause it to seek out and destroy cancer cells.
Within three weeks of contacting the Institute in late 2023, Bacon was transferred to Mexico from her home in Florida for her first treatment.
A representative from the Institute told the Daily Mail it administers this treatment abroad, in part, so it can use immunotherapy drugs not currently approved in the US. They also said it can save patients money, explaining that an immunotherapy drug that costs $10,000 in the US can cost just $1,000 in Mexico.
In the experimental procedure, doctors fire high-voltage electrical waves at the tumor in a method called Pulsed Electric Field (PEF) ablation therapy. This aims to kill cancer cells and alert the immune system to the disease.
Then, the team infuses a cocktail of immunotherapy drugs directly into the tumor, which also helps to reveal the cancer to the immune system.
Almost no immunotherapy drug has been FDA approved for injection directly into a tumor.
The treatment differs from more widely used methods, in which the immunotherapy drugs are infused into patients via a vein in their arm. The Williams Institute argues that this confuses the immune system and makes the treatment less effective.
Dr Barry Hahn, an emergency medicine physician, told the Daily Mail that patients looking to try novel cancer treatments should exercise a 'measure of caution.'
'Just because something is not FDA approved doesn't mean it can't work, and something that is FDA approved won't always work,' he said.
'I am a big believer in the body healing itself and I am all for trying new therapies, but I think this should be taken with a measure of caution. I am not involved in the research, but you can't make any general conclusions from a population of one or small population size.'
Bacon is shown above at the Williams Cancer Institute, preparing to receive her experimental treatment
The Williams Cancer Institute has not presented data on how effective its treatment has been for breast cancer patients.
But in June, it revealed at the American Society of Clinical Oncology's (ASCO's) annual conference in Chicago, that eight out of 15 patients, or 53 percent, with stage four prostate cancer saw signs of their cancer disappearing after the treatment.
Doctors involved in the study underlined how sick the patients were, saying 13 had cancers that had spread to their bones and, in every case, their disease had not responded to standard treatments.
Within a month of her first treatment at the center, Bacon's tumor shrunk by 92 percent.
'A lot of the doctors were like, "Wow." They were expecting good results, especially because of my age, but not expecting it to be this fast,' she told the Daily Mail.
Breast cancer is the most common type of cancer diagnosed in women, with about 315,000 new cases every year, according to the American Cancer Society.
Behind lung cancer (42,000 annual deaths), it is the second leading cause of cancer death among women.
Breast cancer patients are around 63 years old on average, but the cancer, like many others, is becoming more common in younger people.
A 2024 study found that diagnoses of breast cancer among people under 50 years old has been rising by nearly two percent each year since 2010.
Bacon is pictured above. She has now been declared effectively cancer-free and says she plans to live life to the fullest
Doctors are not sure why breast cancer cases are rising among women, but have suggested that sedentary lifestyles and pollutants in the environment might be to blame.
After receiving the initial results, Bacon went for two more infusions over the course of three months. Her tumor completely disappeared, she told the Daily Mail.
Bacon said she was declared effectively cancer-free in July 2025, after about a year of scans and monitoring showed the cancer had not returned.
Typically, doctors wait for five years after a tumor has completely disappeared before they declare someone cancer-free.
She still undergoes regular scans back at her local hospital to check for the cancer, but doctors have told her that, as of now, there have been no signs the disease has returned.
'It's changed my life,' Bacon told the Daily Mail, 'It brought me back to my faith and, you know, it just gave me a second chance at everything. I don't take it for granted anymore.'
To others going through diagnosis, 'I would say... life is not over. You know, do your research. Don't allow one doctor to tell you what you need to do. Don't allow fear-mongering. Just, again, be your own advocate. Do your research.
'There's different ways of healing. It is not a one-size-fits-all approach.'

Read MoreI’m so grateful to Dr Williams and his team.
It was a big step to go from Sydney, Australia to Mexico City for his treatment but it’s all been worthwhile.
I was stage 4 NSCLC with mets to my lymph nodes.
His recommended treatment, supplement regime, off label drugs and pre and pro biotics stopped growth immediately, this was followed over 3 months with a continuous reduction in size of all tumors and no new mets.
Dr Williams then suggested I follow up with Keytruda infusions in Australia and so far this in combination with his intertumoral injections has been successful….which was exactly what he predicted would happen.
The whole procedure took one week. (I’d previously had Chemo and radiation in Australia with little success) His care and professionalism are second to none and he and the Williams Cancer Institute team guided my wife and I every step of the journey and continue to do so.
He always personally checks my 3 monthly scans and reports back asap and constantly updates me with new research outcomes that might assist with my recovery. You have nothing to lose and everything to gain by organizing a Zoom meeting with him for his considered point of view.
He's refreshingly honest and approachable which are sometimes rare qualities in the oncology business.
Plus he's a great guy who takes the time to explain how his treatment works and why it could work so well in your situation.
I highly recommend him and the Williams Cancer Institute.
Feel free to reach out to me if you'd like a discussion as I found talking to previous patients was very helpful.

Stage 4 Prostate Cancer
I was diagnosed with advanced prostate cancer in July 2018. After several high PSA readings, a biopsy and MRI were scheduled and revealed significant cancer in the prostate with a Gleason 3+4=7 score with extracapsular extension along with a lymph node abnormality.
Read MoreI was diagnosed with advanced prostate cancer in July 2018. After several high PSA readings, a biopsy and MRI were scheduled and revealed significant cancer in the prostate with a Gleason 3+4=7 score with extracapsular extension along with a lymph node abnormality.
At the end of 2019 I consulted with a leading prostate cancer specialist who confirmed my cancer was metastatic and was not curable by approved standard of care treatments, including systemic immunotherapy because my cancer doesn’t possess the specific genetic mutations to make that viable.
Dr. Williams explained in careful detail the combination of four immunotherapy agents that would be used in a treatment series. It was a fascinating discussion of how each drug would work to amplify immune system function or suppress cancer evasion activity, and how those processes would work synergistically to maximize an attack on the cancer. Very importantly, he also explained the necessity for supplements taken prior to the treatment to boost the immune system.
I was treated with a series of three intratumoral immunotherapy injection procedures over the course of a week in January 2020. All my reactions to the drugs were exactly as predicted. Dr. Williams’s colleagues Dr. Carlos Vargas, biomedical engineer Eduardo Cortés, and all the supporting doctors and staff were fantastic. I’m so lucky to have had the benefit of their knowledge and expertise of the highest level.
My discovery of The Williams Cancer Institute at the end of a year and a half of research was a miracle. Recent scans in 2021 and 2022 with the latest PSMA/PET/CT technology show no metastatic activity, no lymph node abnormalities, no progression of cancer in the prostate, and PSA levels are trending down to new lows. I feel great and have avoided all the discomfort and dysfunction that results from legacy surgery, radiation, and chemotherapy treatments. Dr. Williams and the Institute are at the forefront of the most important breakthroughs in immunotherapy which will revolutionize the entire field of oncology. If you are a cancer patient it is imperative that you consult with the Institute to see if these new immunotherapy techniques are a solution.
Thanks to Dr. Williams I have a whole new life ahead.

Stage 4 Prostate Cancer
I am a patient of Dr. Jason Williams; I was first diagnosed with prostate cancer in 2011. After following traditional medicine for several years, my cancer spread. On November 25, 2020, I was diagnosed with stage 4 Prostate Cancer, with multiple metastases to my bones, with the most significant lesion on my spine.
Read MoreI am a patient of Dr. Jason Williams; I was first diagnosed with prostate cancer in 2011. After following traditional medicine for several years, my cancer spread. On November 25, 2020, I was diagnosed with stage 4 Prostate Cancer, with multiple metastases to my bones, with the most significant lesion on my spine.
The prognosis was less than one year to live and zero hopes for a cure by traditional means. After several months with no improvement and associated symptoms worsening, I needed a quick solution.
I was referred to Dr. Williams by my ex-wife. She went to Dr. Jason Williams in 2016 with Stage 4 Lung Cancer and, after receiving treatment, today remains cancer-free.
After a quick video consultation in early 2021, I felt confident with Dr. Williams’s treatment recommendations, and I booked my flight to Mexico City. Upon arrival in Mexico, I was greeted at the airport by one of the Institutes drivers, a nice young man who transported my two sons and me to our hotel and assisted us with checking In.
On July 13, 2021, I arrived at the Williams Cancer Institute in Mexico City. The staff was very nice, and the facility was very clean/modern. Within a few hours of arriving, Dr. Williams administered a single injection of immunotherapies directly into the largest tumor. Since the tumor was in my bone, Dr. Williams had to give me the shot while inside a CT Scan machine.
I can only imagine the precision and skill required to accomplish such an injection. Within four hours of my procedure, I was able to stand up, hug Dr. Jason Williams, and walk out of the Hospital relatively pain-free. You can see in the scans below that Since my treatment, all of my tumors have disappeared. My PSA remains under a 1. I cannot thank Dr. Jason Williams and the Williams Cancer Institute enough.
I can honestly say today that I owe him my life.

It’s the solution to many cancers. And just as he said, the procedure is 2 to 3 hours, followed by 2 to 3 hour recovery and then you can go out for lunch! I drove us home the next day to Kentucky! It’s affordable, it works, it’s so much easier on your body, and it makes so much
more sense to go after the tumor and not poison your entire body.
My family and I thank the Good Lord regularly for curing me of my lung cancer by Dr. Williams!

Stage 4 Breast CancerAllen Rappert - Stage 4 squamous cell sinus cancer
My name is Tina Willits and in March 2022 I was diagnosed with Stage IV breast cancer that had spread to my lymph nodes and bones. As a fifty one year old wife, mother and grandmother, I was determined to find a path to becoming cancer free and find my health again. My first step was to begin traditional treatments with an oncologist; however, I quickly became frustrated with her approach which was to provide “quality of life” care with a twenty-four-month life expectancy.
Read MoreMy name is Tina Willits and in March 2022 I was diagnosed with Stage IV breast cancer that had spread to my lymph nodes and bones.
As a fifty one year old wife, mother and grandmother, I was determined to find a path to becoming cancer free and find my health again.
My first step was to begin traditional treatments with an oncologist; however, I quickly became frustrated with her approach which was to provide “quality of life” care with a twenty-four-month life expectancy. My oncologist offered chemotherapy but set an expectation that we would only be able to slow the progression of my cancer.
Even with my oncologist’s lack of optimism, I remained determined to find an alternative treatment that would lead to not only stop the progression but eliminate the cancer.
I had heard that some doctors were having great results using immunotherapy treatments, so I began searching online for treatment options. During one of my searches, I came across Dr. Williams book, Immunotherapy Revolution and immediately ordered it from Amazon. I literally read the book in one day and felt strongly that Dr. Williams approach could help me.
My husband is a surgeon and I asked him to read the book from the perspective of a medical doctor. He agreed that Dr. Williams’ treatment made a lot of sense and we decided to reach out to his office.
I contacted Dr. Williams’ office on the Friday of 4th of July weekend. I shared with his friendly staff my prognosis and was assured that my information would be shared with Dr. Williams. I was pleasantly surprised to receive a text message from Dr. Williams the next day, on a Saturday. His passion for helping cancer patients was clear and he texted me supplements to start taking that weekend which would help build my immune system. I cannot express how much it meant to me that he would begin helping me immediately and keep in mind I had not paid him a penny at this point.
The next step was for Dr. Williams to review my medical records and diagnostic images to determine if I was a candidate for his treatment. We were so excited to hear that I was a good candidate and he was able to schedule the procedure within weeks which was critical for my situation because he decided doing the procedure at the halfway point of my chemotherapy treatments would give me a significant advantage. All of the staff members were amazing and helped us to quickly coordinate all the details.
My husband and I flew to Mexico City in late July for my procedure. Dr. Williams staff were waiting at the airport and coordinated taking us to the hotel, hospital and airport. I would be lying to say I was not nervous about going to another country to have a procedure done but his staff was so comforting and the hospital had an entire floor devoted to the Williams Cancer Institute and my anxiety quickly turned to optimism that I would have a great outcome. In fact, after my procedure, I was brought back to my hospital room and met a woman in the room next to me that was about to go in for the same procedure. We shared with each other our strong belief that Dr. Williams would give us our lives back!
My procedure went very well and we stayed a few days just to make sure I would feel well enough to fly. I had the anticipated immune symptoms after the procedure but felt well enough to go out to do some site seeing and dining. I was able to fly home comfortably and had no complications from the procedure. It still amazes me that his treatment has no long term side effects.
It is with much joy that I am able to share that the MRI that Dr. Williams ordered a few weeks after my procedure showed no active cancer and all my subsequent PET Scans continue to show no evidence of malignancies. This was accomplished without radiation which was one of my goals due to the risk of developing other cancers from the radiation. Additionally, Dr. Williams performs a Signaterra blood test monthly on me which measures circulating cancer cells down to a billionth of a cell which has been maintained at zero which prior to his treatment I had circulating cancer cells.
I cannot thank Dr. Williams and his caring staff enough. The entire team celebrates my continued health. I truly believe Dr. Williams’ procedure saved my life and it is so comforting to know that he accomplished this without putting me at risk for additional cancers. I greatly appreciated his passion for staying on the cutting edge of cancer treatments and I continue to recommend him as well as lots of prayers to anyone facing the daunting diagnosis of cancer.
Thank you all

Dr Williams vast knowledge of medicine and expertise in cancer was very welcoming. He gave me Hope and he gave me back my life. Dr Williams' treatment should be in every cancer hospital in the World, It made sense to me to go directly to the tumor and not poison the whole body with chemo and radiation.
God Bless Dr Williams and his team for their tireless research and effort to treat the medically incurables, without them I would not be here as someones' Mom, Aunt, Niece or friend.

Breast cancer (Stage 4)
In February 2012, I was at home in Maryland when I felt an irregular lump in my chest and quickly made a doctor’s appointment. “Come to find out, I had the most aggressive breast cancer my doctor had ever seen in 35 years of practice,” I said. “It was a scary thing and unexpected because I had no history of cancer in my family, no history of breast cancer in any of the women or men. I was 46 years old and just starting a new career.” My doctor laid out traditional treatment options for stage four breast cancer, such as mastectomy, lumpectomy, chemotherapy, and radiation. However, he also told me about a new treatment that Dr. Jason Williams was using in Gulf Shores, Alabama.
Read MoreIn February 2012, I was at home in Maryland when I felt an irregular lump in my chest and quickly made a doctor’s appointment. “Come to find out, I had the most aggressive breast cancer my doctor had ever seen in 35 years of practice,” I said. “It was a scary thing and unexpected because I had no history of cancer in my family, no history of breast cancer in any of the women or men. I was 46 years old and just starting a new career.” My doctor laid out traditional treatment options for stage four breast cancer, such as mastectomy, lumpectomy, chemotherapy, and radiation. However, he also told me about a new treatment that Dr. Jason Williams was using in Gulf Shores, Alabama.
At the time, Dr. Williams was using a minimally invasive procedure called cryoablation, where doctors use live imaging to guide a thin probe into tumors. The probe is cooled below freezing, forming a ball of ice at the tip, freezing and destroying cancerous tissue.
I decided to visit Dr. Williams in Alabama and see if I was a candidate for cryoablation. After some scans in his office and additional scans back home, Dr. Williams confirmed I was a viable candidate.
I returned to Alabama for the procedure, which was mostly painless, and returned twice for follow-up appointments. “I wasn’t in any pain. I had a little soreness, but two hours later, my husband and I were sitting at a restaurant in Gulf Shores having dinner, marveling at the fact that that was my treatment for aggressive breast cancer,” I said.
After the procedure, I went through a few rounds of chemotherapy. I was supposed to have eight rounds of dose-dense chemotherapy, once every two weeks. However, after four rounds, doctors were unable to detect cancer in my blood.
“I didn’t lose my hair, it took a beating, but I never lost my hair. There was no recovery time, no incisions, and no loss of breast tissue, except for what needed to be removed,” I said. “I’ve heard from many friends who had mastectomies, and some women have limitations. I never had that. I didn’t struggle with the mental and physical effects of having to go through something so traumatic.”
Since then, I’ve had many difficult conversations with other women who endured double mastectomies. “When I say hard, I mean, it’s difficult to have access to this information and be able to have that kind of procedure when other women don’t know about this,” I said. “I was blessed to have been in the right place at the right time to know this information, which is why I don’t think it should be gatekept.”
Looking back, I thought my cancer diagnosis was going to be life-changing in the worst possible way. But now, 13 years later, I am the executive director of the Life Plus Foundation, a nonprofit that has brought clean water to over 350,000 people in southeastern Kenya and runs food and education programs in more than 30 countries.
“I feel like on some level, because I found the lump right as I was about to start this job, it was providential,” I said. “It stopped me in my tracks, helped me become more compassionate, and gave me a deeper understanding of true suffering.”

Stage 2 HER2-positive breast cancer
I was diagnosed with Her2+ breast cancer in the Spring of 2023. After meeting with several traditional oncologists, I decided to look for a more holistic treatment approach, and our research led us to the Williams Cancer Institute. Since that time Dr. Jason Williams and his team have been an important part of my overall care team. Under Dr. Williams care I have received Cryoablation, Pulsed-Electric Field (PEF) Ablation and Intratumoral Immunotherapy. I am happy to say that my latest Signatera blood results showed no evidence of disease (NED). I am very grateful for the role that Dr. Williams and his team have played in my current condition."

Open source cancer treatment
At Williams Cancer Institute, we want to improve your cancer treatment.
We can work with your oncologist to enhance your current treatment, no matter the stage of your cancer. If you are receiving chemotherapy, we can improve the results by adding to it. If you are already getting immunotherapy, we might be able to boost the response. Our personalized treatment can often be added to standard-of-care cancer therapies, which we call Standard of Care Plus.
How Does Williams Cancer Institute Help Boost My Standard of Care Cancer Treatment?
We use scientific evidence to help enhance the results patients may get from their standard care, chemotherapy, or immunotherapy. Our goal is to work together with you and your oncologist to make your treatments even more effective.
We understand that oncologists are very busy and focused on providing the standard of care for cancer patients. Our aim is to build on that foundation and offer additional options to improve your treatment beyond the standard approach.
Frequently Asked Questions

Immunotherapy is generally well-tolerated, and many people find its side effects to be milder than those experienced with chemotherapy.
However, as with any treatment, some side effects may occur. These can include mild fever, tiredness or low energy, decreased appetite, flu-like symptoms (such as chills or muscle aches) and discomfort or soreness in the area being treated. Most people find these side effects manageable, and they are often less intense than those commonly associated with chemotherapy. Our medical team will work closely with you to help minimize any discomfort and support your well-being throughout the treatment process.
It is best to avoid antibiotics unless they are absolutely necessary. Our medical team will carefully review your case, including your current treatments and medications. Our goal is not to interrupt your existing therapies but to complement them safely and effectively. If you have any concerns about your medications, please let us know so we can provide personalized guidance.
