Inside Immunity Therapy Center: A Conversation with Dr. Carlos Bautista
For over 30 years, Dr. Carlos Bautista has treated patients with advanced and complex cancers many of whom were told there were no other options.Â
As the founder of Immunity Therapy Center (ITC) in Tijuana, Mexico, Dr. Bautista leads a full-service hospital that offers integrative and immune-based cancer care.
In this exclusive Q&A, Heal Navigator’s Head of Patient Care, Paityn Thorn, sat down with Dr. Bautista to explore what makes ITC’s approach unique, what patients can expect, and why he believes hope still exists even for late-stage cases.
Key Takeaways
ITC combines immune-based therapies, low-dose chemotherapy, and supportive care to treat all stages of cancer especially effective for breast cancer and lymphomas.
Their approach is science-backed but often not available in the U.S. Many treatments are standard in countries like Mexico and Germany.
Treatments are tailored to the individual, with options like dendritic cell therapy, transfer factors, Rife therapy, and repurposed medications.
Patients who follow the full plan including the home protocol see the best long-term outcomes.
The facility offers both inpatient and outpatient care, nutritional support, emotional counseling, and transportation/lodging for international patients.
Meet Dr. Carlos Bautista
What Led You To Open Immunity Therapy Center?
Dr. Bautista: When I was in medical school, I was always questioning treatments and drawn to alternative approaches.Â
Around the time I graduated, my father was diagnosed with lung cancer.Â
He received chemotherapy and radiation, and unfortunately, he passed within three months.Â
That personal experience made me question the conventional path and I then dedicate my life to finding a better way to help people with cancer.
What Have You Learned After 30 Years Of Treating Cancer Patients?
Dr. Bautista: That there are other options even when patients are told there’s nothing else they can do.
 Alternative or functional treatments can work, and most importantly, they give people hope again.
Are There Certain Cancers That Respond Particularly Well To Your Approach?
Dr. Bautista:Â All cancers can respond well, but we tend to see especially strong results in lymphomas and breast cancers. That may be because these respond better to immunotherapies, which are a core part of our approach.
How Is Your Immunotherapy Different From Standard Pharmaceutical Options Like Keytruda?
Dr. Bautista:Â Conventional immunotherapy drugs remove brakes from the immune system drugs like Keytruda work in that way. What we do is more complete.
We stimulate the immune system to recognize and destroy cancer cells using:
- Dendritic cells
- Transfer factors
- Macrophage-activating factors
- LAK therapy
- Mononuclear cell activation (MCA)
These are not vaccines, even though they’re sometimes called that.
They’re highly targeted biological agents that support the immune response.
What Determines Which Therapies You Use For Each Patient?
Dr. Bautista: Every cancer has different weaknesses. Some respond to heat, others to oxygen or immune support. Each therapy targets a specific vulnerability — and they work best when combined strategically.
Do You Use Repurposed Drugs Like Ivermectin Or Metformin?
Dr. Bautista:Â In some cases, yes.
We evaluate whether they will be beneficial and ensure they won’t interfere with our other therapies.
Many patients already come taking those medications, and we continue them if appropriate. But we always use a science-based, case-by-case approach.
What Does A Typical Patient Day At ITC Look Like?
Dr. Bautista:Â Patients usually come for about three weeks.
After airport pickup and intake, they meet with their doctor and with me personally. Treatment starts right away.
We have two daily shifts morning and afternoon Monday through Saturday.
Patients receive therapies on the fourth floor, and are assigned a doctor and nurses who support them each day.
Do You Offer Emotional Or Nutritional Support Too?
Dr. Bautista:Â Yes.
We have:
- A full nutrition team that provides meals based on a low-glycemic, anti-cancer diet
- A dental department to address infections or mercury fillings that may affect the immune system
- Emotional support counselors, offered by request, with full respect for religious or personal beliefs
What’s The Difference Between Inpatient And Outpatient Care At Your Clinic?
Dr. Bautista:Â Outpatients come in for treatment and stay offsite often in our nearby apartments. Inpatients stay in the hospital, with 24-hour nursing care.
Inpatient care is ideal for people needing more support or those who come alone and need supervision.
What Is The Home Protocol, And Why Does It Matter?
Dr. Bautista:Â The home program is essential.
After their time at ITC, patients receive customized therapies and devices to continue care at home including immunotherapies, Rife machines, biomagnetic tools, and more.
Those who follow their home program and return regularly for follow-up tend to do much better.
Do You Offer Low-Dose Chemotherapy?
Dr. Bautista:Â Yes we use two types:
- DPT (DMSO Potentiation Therapy):Â Delivers low-dose chemo directly to cancer cells, minimizing damage to healthy cells.
- IPT (Insulin Potentiation Therapy):Â Uses insulin to open glucose receptors, allowing cancer cells to absorb low-dose chemo.
We typically prefer DPT, as it avoids hypoglycemia and is better tolerated. Both are effective and much gentler than conventional chemotherapy.
Who Benefits Most From Your Program Early Or Late-Stage Patients?
Dr. Bautista:Â We treat all stages. Ideally, patients come before starting conventional treatments. We see stronger immune responses that way.
But we also help patients who’ve already undergone chemo or radiation. We just need more time to rebuild and detox the immune system.
What Would You Say To People Who Think Integrative Care Is Unproven?
Dr. Bautista: All of our treatments are based on science and are used in other countries as part of conventional care especially in Europe and Mexico.
Just because something isn’t approved in the U.S. doesn’t mean it’s unsafe or experimental.
What Do You Want Patients To Know Before Coming To ITC?
Dr. Bautista:Â That these options exist.
Many people don’t know there’s another way until it’s too late.
I want patients to know they have choices. And that there’s hope.
For Dr. Bautista and his team at Immunity Therapy Center, the message is clear:
There are always options to explore, and often more hope than patients realize.
By combining science-based integrative treatments, individualized care, and a strong home program, ITC aims to support not only better outcomes but also quality of life. For families weighing their choices, understanding what ITC offers can be the first step toward feeling empowered in the face of cancer.
