Discover the only Fully Accredited and Certified Alternative Cancer Treatment Program in Tijuana, Mexico.


Our doctors are world leaders in the use of immunotherapy for cancer treatment. Using our specialized techniques, we teach the body how to fight cancer on its own.

Immune Support and Regulation

In order to support remission, we strive to get the body back into balance. We do this through carefully designed nutrition plans that include specialized supplements.

Integrative Medicine

Traditional medicine relies on chemotherapy and radiation. We use all of the tools we have to promote healing - and we use them all together. We don't believe in a one size fits all approach. We treat the whole person.

Patient Stories. Be Inspired.

“The doctors are absolutely fantastic.
They give me all the time I can ever ask for.”

Treatment at the Functional Oncology is about the individual patient, but it is also about support and community. Our patients become lifelong friends with each other as well as with the doctors and staff. This is why our patients are so exuberant about spreading the word about Functional Oncology. See what a patient says about his time with us in his own words.
