The Innovation That Turns Your Tumor Into Your Vaccine
Ablation + Intratumoral Immunotherapy
Our pioneering single-needle procedure destroys cancer cells while simultaneously injecting immunotherapy directly into the tumor bed—creating a personalized cancer vaccine inside your body.
This combination delivers: local tumor destruction PLUS systemic immune activation against cancer throughout the body and is what makes Williams Cancer Institute’s approach unique across the world.
ABLATION
Tumor Destruction
Destroys tumor cells and releases tumor antigens, making hidden cancer visible to the immune system.
PEF Ablation
Nanosecond, biphasic electrical pulses destroy cells without heat. Preserves tumor antigens and triggers immunogenic cell death (ICD).
INTRATUMORAL IMMUNOTHERAPY
Immune Activation
Powerful immune-stimulating drugs injected directly into the tumor—100% delivered to target vs. 0.5-2% with IV.
Immunotherapy Classes
• Monoclonal Antibodies
• Oncolytic Immunotherapies
• Chemotherapy
• Pattern Recognition Receptor Agonists
• Natural Therapies
• Immune Cell-Based Therapies
• Integrative Therapies
• Cytokines
• Nucleic Acid Sequences
THE INNOVATION
Your Tumor Becomes a Personalized Cancer Vaccine
Delivered through a single needle in one outpatient procedure. The ablation releases tumor antigens while immunotherapy supercharges the immune response—training your body to hunt cancer throughout your entire body.
Your Body’s Unique Cancer Fighting Solution with Immunotherapy
About Us
At Williams Cancer Institute, we enhance standard cancer care with advanced, minimally invasive therapies.
You don’t have to abandon your current oncologist or treatment plan— our approach, called Standard of Care Plus, is designed to complement existing therapies with fewer side effects and greater effectiveness. Each treatment is carefully tailored to your specific medical and personal needs, ensuring that your cancer care plan is as unique as you are. We design every procedure using a personalized approach that considers your tumor type, location, stage, and overall health. We can go directly to the tumor, enhancing the immune response. In addition, we will provide many off-label medications and supplements, to make any cancer treatment better. You don’t have to choose between us and your current oncologist, we will be glad to work with your current doctor to make the overall care even better.
Why Inject Directly Into the Tumor?
The cure for cancer is within you
There is no better location for the immune system to learn to attack a cancer than within the tumor itself. These immunotherapy drugs can have powerful effects, but they need to be in the right location. Spatial-omics confirms that immune spacing and timing is critical to an effective anti-tumor immune response.
You can do everything possible to stimulate your immune system with typical immunotherapy drugs, but if the immune cells never get to the tumor, the immune cells are not correctly spatial oriented, the therapy cannot work. Intratumoral delivery solves this problem.
Key Advantages
100% of medication delivered to target
Reduced systemic side effects Lower
doses required (reduced cost)
Transforms “cold” tumors into “hot” tumors
Procedures
At Williams Cancer Institute, we use a variety of procedures and carefully evaluate which ones are best for each patient. Our team will guide you every step of the candidacy process to choose the right combination of treatments for your unique case. We have extensive experience with the following treatments:
Intratumoral Immunotherapy
Intratumoral immunotherapy involves injecting a cancerous tumor directly with treatment to help create an immune response, with the goal of using the tumor as its own vaccine and with less chance for toxic side effects.
PEF Pulsed Electric Field Plus Intratumoral immunotherapy
PEF delivers a nanosecond electrical pulse to a cancer cell that causes an immune response. We combine this with intratumoral immunotherapy to further stimulate the immune system to attack the cancer at that tumor location and throughout the body.
Cryoablation plus Intratumoral Immunotherapy (AblationVaxTM)
Cryoablation kills cancerous tumors from within by freezing them, which releases tumor antigens that can target additional cancer cells. Cryoablation combined with intratumoral immunotherapy can create a strong and effective immune response while minimizing side effects.
Breast Cancer Cryoablation
Breast cancer cryoablation uses extreme cold to destroy breast cancer cells in patients who are not eligible for surgery.
Intraarterial Infusion of Immunotherapy
Intraarterial infusion of immunotherapy uses the tumor’s arteries to deliver higher medication amounts at a lower dose directly to the tumor.
Intratumoral Chemotherapy plus Immunotherapy
Treatment with intratumoral immunotherapy plus chemotherapy is when a cancerous tumor is injected directly with both immunotherapy and chemotherapy to help enhance the treatment effect.
Cancer treatment should start at the biopsy.
When cancer is first diagnosed at the biopsy, it is the first chance for treatment. Current standard of care, only a biopsy is performed, and treatment occurs later. This is a missed opportunity, as a needle has been placed in a tumor, and could have been used to inject medication, such as immunotherapy, to start the cancer treatment. Instead, in most cases, the biopsy is done without injection of medication, which can inflame the tumor, making it more aggressive and the time allowed between biopsy and treatment is just given time for the cancer to grow and spread. This is the error of the current standard of cancer care treatment. Sticking a needle into a tumor without injecting medication is a lost opportunity. We hope to change this.
Treating Cancer without directly targeting the tumor doesn’t make sense.
Current standard of care treatment for advanced cancers involves giving medications by IV or mouth, but not directly to the tumor. Very little of these medications actually make it to the tumor. Doesn’t it make more sense to put medication directly into a tumor? Certainly, we can biopsy these tumors, so it means we can access with a needle and inject medication. Clearly not putting medication directly into the tumor is a huge mistake.

I’m one that doc Williams saved. Stage 4 squamous cell sinus cancer eating into my orbital
bone and skull bone 10 days away from eating into my brain 3 treatments later the low dose chemo
cocktail and heat ablation ate 85% of the tumour on the way to zero.

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

The world is so blessed to have Dr. Jason Williams eager to kill cancer one tumor at a time! He
was inspired as a young man by the death of his grandmother to cancer. I was fortunate enough to
have him do ablation on my lung. 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

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. 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

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. 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

Stage 4 Prostate Cancer


I’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
