Immunotherapy is a highly successful treatment in the fight against cancer, thanks to the excellent drugs used for this purpose. These drugs unlock the immune system so the body can fight against this disease. That is why cancer is among the leading causes of death worldwide, and immunotherapy has been a great contribution to its fight, as it helps the immune system fight cancer cells.

The immune system is composed of white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow, and it detects and destroys abnormal cells that infiltrate the body. It works by preventing or slowing down the growth of many types of cancer, but cancer cells can sometimes overcome their defenses. In those cases, immunotherapy treatments can help work the immune system to fight cancer cells found in the body.

It is important to mention that not all cancer patients are candidates for immunotherapy, as it often depends on the type of cancer and how advanced it is at the time the treatment is requested. Additionally, the use of immunotherapy also depends on whether current cancer treatment guidelines and data support immunotherapy as a cancer treatment. Generally, ideal candidates are those who have advanced cancer and have exhausted other conventional treatment options.

Immunotherapy has some advantages, such as having fewer immediate and long-term side effects. Other therapies are related to heart problems, surgical complications, and issues with hormones and memory. In addition, patients have a high chance of continuing immunotherapy treatments for longer periods without sacrificing their quality of life.

Currently, several types of cancer, such as melanoma and non-small cell lung cancer, have been approved for this treatment. Other cancers approved for immunotherapy treatments include liver cancer, stomach cancer, cervical cancer, bladder cancer, some breast cancers, and lymphoma. Therefore, immunotherapy remains one of the most effective treatments in the fight against cancer.
