From No Options in California to Remission in Mexico

In 2020, a woman from Northern California felt a lump while putting on lotion. She let it go for a few months — as many people do — and when it was still there, she got it checked. The biopsy confirmed breast cancer: intraductal carcinoma, stage 2. Her oncologist immediately recommended chemotherapy. She had other ideas.

Her journey from that diagnosis to cancer-free remission spans five years, two visits to the Immunotherapy Institute in Tijuana, a bilateral mastectomy, a recurrence, hormone therapy, and two separate decisions to decline radiation. It is one of the most complete and honest testimonials we have heard — a patient who pursued both alternative and conventional care, made deliberate choices at every turn, and came back to Tijuana not because things went wrong, but because they went right.

This is the story of what tailored, integrative cancer care looks like when a patient refuses to be treated as a protocol.

A Diagnosis in 2020 — and a Decision Not to Start With Chemo

From the moment her cancer was confirmed, this patient was clear about one thing: she wanted to explore every option before agreeing to a treatment she felt would cause serious harm. She had prior knowledge of people who had beaten cancer through plant-based diets and alternative approaches, and that awareness made her unwilling to simply accept the standard protocol without first understanding what else was possible.

"Because of that prior knowledge, that is what made me want to pursue other options," she said. She began researching alternative treatments — not as a way to avoid care, but as a way to find care that fit her values, her body, and her vision of what healing should look like. That search led her to an Ayurvedic doctor who mentioned the Immunotherapy Institute. She looked them up, studied the offerings, and was particularly drawn to the low-dose chemotherapy option and the treatments simply not available to her at home. "The fact that it was just options that I didn't have at home — I was really, really interested in coming here."

What She Wanted — and What Conventional Medicine Offered

The patient's concern with conventional cancer care was not that it doesn't work — it was that it doesn't differentiate. "At home, it is not tailored. It is a dose that is recommended for your type of cancer. No matter what your condition is, you and another person could have very different backgrounds and bodies, but you're given the same thing."

For a woman who believed deeply in treating the whole person, this cookie-cutter approach felt fundamentally wrong. Chemotherapy was immediately recommended after diagnosis — not as one of several options, but as the obvious first step. When her cancer returned in 2024 after her mastectomy, her oncologist recommended full radiation to the chest and armpit. She had declined radiation once before. Now she was being pressured toward it again — despite having no visible cancer on her scans. "She had me pretty intimidated," the patient admitted. "I was about to do the radiation." But after months of research, prayer, and weighing the pros and cons, she made the same choice she had made before: she came back to Tijuana instead.

What Drew Her to the Immunotherapy Institute — Twice

Her first introduction to the Immunotherapy Institute came through an Ayurvedic doctor who recommended the clinic. What she found on their website resonated immediately: low-dose chemotherapy, integrative protocols, and options she simply couldn't access at home. A phone call with Dr. Perez sealed her confidence. "He's very well spoken, very educated, was very thorough in what he explained," she said. What struck her most was the integration of both conventional and alternative oncology — not one or the other, but both, tailored specifically to the patient.

"You have the alternative and traditional oncologic care, but you tailor it to the patient. That is what I thought was really great." Two years later, with clean scans and a recommendation from her U.S. oncologist to pursue radiation she didn't want, she made the choice again — this time for CAR T Cell therapy as a way to prepare her immune system to protect her going forward. The most meaningful thing about the institute, she said, is simply having the option. "Just knowing that there's a clinic that gives you the option to have tailored care."

Two Visits, One Consistent Philosophy: Treat the Person, Not the Protocol

Her first stay at the Immunotherapy Institute in 2023 was comprehensive. Treatment included high-dose Vitamin C IVs, Laetrile (B17), zinc, selenium, a detoxification sauna, a Rife machine, autologous cell transfer therapy, and hyperthermia — a wide-ranging integrative protocol designed around her specific case and stage of disease. At the recommendation of the institute's doctors, she also subsequently underwent a bilateral mastectomy at home, with clean margins and five lymph nodes removed. She declined radiation after the procedure and continued with alternative therapy and a healthy diet.

When the cancer returned in early 2024 — two small lumps in the armpit — she began hormone-blocking therapy (Tamoxifen and Lupron) with an oncologist at home, which worked rapidly: the lumps were gone within six months. But when that same oncologist recommended a full course of radiation to the chest and armpit, she came back to Tijuana for her second visit instead — this time for CAR T Cell therapy. Her understanding of the treatment reflects both her intelligence and the quality of education she received from the team: "That is taking my own cells and processing them in the lab and making them smarter so that they can recognize my cancer at its current state, if it has mutated, if it's different than how it was five years ago."

She was back in Tijuana in 2025 — not because the cancer had returned, but because it hadn't.

Cancer-Free, and Back by Choice

The clearest signal of this patient's experience is the reason for her second visit: she returned not out of necessity, but out of confidence. Her scans showed no cancer. Her oncologist at home had nothing more urgent to offer than radiation. She chose to come back to the Immunotherapy Institute for a personalized booster — a proactive step to keep her immune system calibrated and her remission intact.

"I've had a great experience, and it was satisfactory enough that I came back a second time without having any worries," she said. "And I've been safe. I've enjoyed my time. I would definitely recommend coming." She addressed the fear many patients carry about seeking treatment abroad with the directness of someone who has now done it twice: "The fear for people going out of the country is just because it's different. It's different than home and you're not sure. But the doctors are qualified. They're very well educated. They take great care of the patients." The thing she values most — beyond any individual treatment — is access. "The fact that the patients have access to the doctors all day throughout the treatment is great. Because at home, you've got a short time limit with the doctor. Here, if the doctor's sitting in the room with you, you can ask him questions."

“I came back a second time without having any worries. The doctors are qualified, very well educated, and they take great care of the patients. Don't be afraid to come — you're well taken care of.”

Key Takeaways from This Breast Cancer Journey

Take the Next Step

This patient's story doesn't fit neatly into either the conventional or alternative medicine narrative — and that's exactly the point. She used both. She made informed decisions at every stage. She declined treatments she didn't believe were right for her and pursued ones she did. And she is cancer-free.

The Immunotherapy Institute exists for patients who want that kind of agency. Who want to be treated as an individual, not a protocol. Who want a team that explains things thoroughly, makes itself available throughout the day, and builds a plan around who you actually are. If that sounds like what you've been looking for, it's time to reach out.
