A Cancer Researcher With Brain Mets Chose Immunotherapy First
Dr. Ernesto Lira Jr. is 69 years old, lives in San Antonio, Texas, and has spent much of his career in cancer research — specifically as a flow cytometry consultant for leukemia and lymphoma laboratories. He knows how cancer behaves at the cellular level. He understands immune function, cell signaling, and the mechanisms by which the body fights disease. When he was diagnosed with metastatic prostate cancer that had spread to his brain, his bones, and his lungs, that knowledge shaped every decision he made.
He did not start with chemotherapy. He did not do radiation. He protected his immune system deliberately — using complementary medicine to keep it strong — and then he came to the Immunotherapy Institute in Tijuana.
He arrived unable to walk. His cerebellar metastasis had affected his motor function, his balance, and his mobility. He came in a condition that most oncologists would have met with aggressive systemic chemotherapy. Instead, he came to a clinic that could deploy his own immune system — preserved and intact — against the cancer that had spread to the most dangerous possible locations.
He can walk again. And his message to every cancer patient he meets is the same: "Immunotherapy should be the first option, not the last."
Meet Dr. Ernesto Lira Jr.: A Scientist Who Chose His Own Protocol
Dr. Lira is not a passive patient. He is a scientist with decades of experience in cancer biology — a man who has spent his career studying the same cells and mechanisms that were now mobilized against him. When his prostate cancer metastasized to his brain, his bones, and his lungs, he was in a position that few cancer patients occupy: one of genuine clinical expertise combined with an urgent personal stake.
He used that expertise deliberately. Rather than accepting the conventional oncology protocol — aggressive chemotherapy to reduce the tumor burden, followed potentially by radiation — he made a calculated decision to protect his immune system. He understood that chemotherapy, while effective at killing cancer cells, also devastates the immune system that the body relies on to fight the disease on its own. He chose, as a scientist who understood the tradeoff, to arrive at the Immunotherapy Institute with an intact immune system that could be deployed against his cancer — rather than one that had been compromised by the very treatment meant to save him.
That decision required both knowledge and courage. For Dr. Lira, it was simply the logical conclusion of everything he had spent his career learning.
Metastatic Prostate Cancer in the Brain, Bones, and Lungs — and a Critical Decision
Metastatic prostate cancer that has reached the brain represents one of the most serious presentations of the disease. The cerebellum — where Dr. Lira's metastasis was located — controls coordination, balance, and movement. When cancer grows there, the effects are immediate and debilitating. Dr. Lira arrived at the Immunotherapy Institute unable to walk properly — his motor function compromised by the cancer pressing on the cerebellum.
The standard response to this clinical picture, within conventional oncology, is aggressive. Systemic chemotherapy for the prostate cancer. Radiation or stereotactic radiosurgery for the brain metastasis. Both approaches carry significant risks, particularly for a 69-year-old patient, and both would have substantially compromised the immune system that Dr. Lira had worked to preserve.
He understood the tradeoff at a cellular level. Chemotherapy kills cancer cells — but it also kills the immune cells, including the T cells and natural killer cells, that the body depends on to mount its own sustained response. A devastated immune system cannot be the basis for immunotherapy. Dr. Lira arrived in Tijuana with a full, functional immune system, ready to be directed against his cancer — a resource that chemotherapy would have largely destroyed.
Everything Under One Roof — and Immunotherapy That Could Actually Work
Dr. Lira chose the Immunotherapy Institute for reasons that reflect both his scientific knowledge and his practical instincts. The clinic offered what he describes as "everything under one roof" — not a fragmented approach where the patient coordinates between multiple specialists and facilities, but an integrated program where immunotherapy, nutritional support, detoxification, and whole-person care are delivered by a single coordinated team.
For a cancer researcher, the scientific basis of the institute's protocols mattered as much as the clinical environment. He had arrived with a preserved immune system specifically to make immunotherapy maximally effective. The Immunotherapy Institute's team was capable of meeting him where he was — building a protocol around his intact immune function rather than starting from a compromised baseline.
"Immunotherapy should be the first option," he says now, with the authority of a man who has lived both the science and the experience. "Not the last." This is not the sentiment of a desperate patient who tried everything else and came to Mexico out of options. This is the measured, scientifically grounded conclusion of a cancer researcher who understood what he was doing from the beginning — and chose the Immunotherapy Institute as the setting in which to do it.
A Preserved Immune System, Deployed Against Cancer — From Cerebellar Mets to Walking
Dr. Lira's treatment journey at the Immunotherapy Institute reflects the clinical value of his pre-arrival strategy. By protecting his immune system through the diagnostic period and forgoing chemotherapy and radiation, he arrived in Tijuana with immune resources that most patients at his stage no longer have. The institute's team was able to work with that — deploying immunotherapy protocols against a cancer that hadn't been made more aggressive by prior systemic treatment, and a body that hadn't been depleted by months of chemotherapy.
The cerebellar metastasis — the most immediately disabling of his cancer's manifestations — was addressed as part of a comprehensive program. And the results in his motor function have been meaningful: Dr. Lira arrived unable to walk properly, and he is walking again.
The clinical environment matched his expectations. The team is qualified. The medicine is scientifically grounded. And the philosophy of the institute — treating the whole person, not just the tumor; deploying the immune system rather than suppressing it; offering everything under one roof rather than fragmenting care across disconnected specialists — aligns precisely with what Dr. Lira, as a cancer researcher, believes represents the best available approach to treating his disease.
His message to patients, delivered with the conviction of someone who has spent decades in cancer research and is now living his own conclusions: Protect your immune system. Come to immunotherapy first. Don't wait until it's your last resort.
Walking Again — and a Scientist's Case for Doing It Differently
Dr. Ernesto Lira Jr. arrived at the Immunotherapy Institute unable to walk, his body invaded by cancer in three organ systems, his prognosis uncertain. He is walking again. That recovery — partial or substantial, still unfolding — is the practical result of a strategy he designed with scientific intention and executed with the support of a team in Tijuana that was capable of meeting him where he was.
But the outcome Dr. Lira is most invested in sharing is not his own. It is the insight that his experience represents for every cancer patient who comes after him. He has spent a career in cancer research. He has worked in leukemia and lymphoma labs. He has seen, at the cellular level, what happens when the immune system is compromised by the treatment designed to fight the disease. And his conclusion — stated with the calm authority of a man who knows exactly what he is saying — is that the field has the order wrong.
"Immunotherapy should be the first option, not the last." Not for every patient, in every situation. But for patients who can access it, who can protect their immune system long enough to make it available, who can find a clinical team capable of deploying it — immunotherapy is not the thing you try when everything else has failed. It is the thing you build toward from the beginning.
“Immunotherapy should be the first option, not the last. I came here with my immune system intact — intentionally. That is what gave the treatment the best chance to work.”
Key Takeaways from Dr. Ernesto's Story
Dr. Lira's perspective is uniquely valuable — equal parts patient experience and scientific expertise. His key observations:
✓ A former cancer researcher and physician, Dr. Ernesto Lira Jr. MD, chose the Immunotherapy Institute for his own metastatic prostate cancer treatment — including brain, bone, and lung metastases — and arrived walking again after a cerebellar metastasis had compromised his motor function.
✓ The decision to preserve the immune system before beginning immunotherapy is scientifically intentional and clinically significant. Dr. Lira declined chemotherapy and radiation specifically to ensure he arrived at the Immunotherapy Institute with immune resources sufficient to support an effective immunotherapy protocol.
✓ The Immunotherapy Institute's 'everything under one roof' model — integrating immunotherapy, nutritional support, detoxification, and whole-person care in a single coordinated program — reflects the kind of clinical coherence that Dr. Lira values from his scientific background.
✓ Immunotherapy as a first-line approach — rather than a last resort after chemotherapy has failed — is Dr. Lira's scientifically grounded recommendation, informed by decades of cancer research and his own lived experience at the Immunotherapy Institute.
✓ Metastatic prostate cancer patients with brain involvement who have been told their options are limited should know that the Immunotherapy Institute offers integrative immunotherapy protocols designed to address multi-site metastatic disease, including cerebellar metastases.
Frequently Asked Questions
Questions we hear from metastatic prostate cancer patients and those considering immunotherapy as a primary treatment approach:
Can immunotherapy be used as a first-line treatment for metastatic prostate cancer instead of chemotherapy?
Dr. Lira's case makes exactly this argument — that for patients who can preserve their immune system and access effective immunotherapy early, the sequence of treatment matters enormously. The Immunotherapy Institute offers integrative immunotherapy protocols for metastatic prostate cancer that can be used as a primary approach rather than a last resort. Candidacy and specific protocol design are determined through a detailed consultation with the clinic's lead physician, based on the patient's current condition, immune status, and disease staging.
Can the Immunotherapy Institute treat prostate cancer that has spread to the brain?
Yes. Dr. Lira's case involved cerebellar metastasis — one of the more challenging presentations of metastatic prostate cancer — along with bone and lung involvement. The Immunotherapy Institute's integrative protocols address the systemic disease, supporting the immune system's ability to respond to cancer across all affected sites. The clinic's approach is whole-person and multi-site, rather than organ-specific, which is particularly relevant for patients with multi-system metastatic disease.
Why does preserving the immune system before immunotherapy matter?
Conventional chemotherapy kills rapidly dividing cells — including cancer cells — but also damages the immune system, including the T cells and natural killer cells that immunotherapy relies on. Dr. Lira, a former cancer researcher, chose to forgo chemotherapy before arriving at the Immunotherapy Institute specifically to ensure he had an intact immune system available for treatment. This is not a universally applicable approach, but for patients who are able to protect their immune function, it can significantly improve the effectiveness of subsequent immunotherapy.
What does 'everything under one roof' mean at the Immunotherapy Institute?
Dr. Lira used this phrase to describe the integrated, coordinated nature of care at the Immunotherapy Institute — where immunotherapy, nutritional support, detoxification therapies, physical therapy, and physician oversight are all delivered by a single clinical team working in the same facility. This contrasts with the fragmented care model common in conventional oncology, where patients often navigate between multiple specialists, facilities, and schedules. The Immunotherapy Institute's model means that every element of the protocol is designed and executed in coordination.
Is the Immunotherapy Institute appropriate for patients in their late 60s or 70s with complex, multi-site metastatic disease?
Yes. Dr. Lira is 69 years old and arrived with cancer in three organ systems, including the brain. The Immunotherapy Institute's integrative approach is designed to work with the patient's current physical state and immune resources — which is particularly important for older patients whose bodies may not tolerate aggressive chemotherapy well. The team builds protocols around the individual's specific capacity, which makes the institute well-suited to patients whose age or condition makes conventional oncology's standard protocols more dangerous than beneficial.
