Colorectal Cancer Treatment in Mexico

Colorectal cancer is one of the most common types of cancer, affecting the colon or rectum and often developing gradually over time. At Immunotherapy Institute, we offer a comprehensive, integrative approach that combines advanced medical treatments with immune system support—designed to help patients manage the disease while maintaining quality of life.
What Is Colorectal Cancer?
Colorectal cancer begins in the large intestine, which includes the colon and rectum. Most cases develop from abnormal growths called polyps that can become cancerous over time.
Because this type of cancer can progress without clear symptoms in its early stages, timely evaluation and personalized care are essential for improving outcomes.
Symptoms of Colorectal Cancer
Symptoms can vary depending on the stage and location of the tumor. Common signs may include:
- Changes in bowel habits, such as diarrhea or constipation
- Rectal bleeding or blood in the stool
- Abdominal discomfort or cramping
- Unexplained fatigue or weakness
Diagnosis and Conventional Treatment
Diagnosis typically involves procedures such as colonoscopy and biopsy to confirm the presence of cancer and determine its stage. Imaging studies may also be used to evaluate the extent of the disease.
Treatment often includes surgery to remove the tumor, sometimes combined with chemotherapy or radiation therapy depending on the stage and location of the cancer.
An Integrative Approach to Colorectal Cancer Treatment
At Immunotherapy Institute, we complement conventional treatments with therapies designed to support the immune system and improve the body’s ability to respond to treatment. Our approach focuses not only on controlling tumor growth, but also on strengthening overall health and resilience.
Treatment plans may include advanced immunotherapy, metabolic and nutritional support, and therapies aimed at enhancing treatment effectiveness while minimizing side effects. Each program is personalized based on the patient’s condition, diagnosis, and medical history.
Supporting the Body Throughout Treatment
Maintaining strength and stability during treatment is essential. Our programs include targeted nutrition, immune support, and carefully selected therapies designed to help patients better tolerate treatment and maintain their quality of life.
By addressing inflammation and supporting cellular health, we aim to create an internal environment that supports recovery and long-term wellness.
Personalized Care for Every Patient
Every case of colorectal cancer is different. That’s why we take the time to understand your full medical history, lifestyle, and goals before designing a treatment plan. Our multidisciplinary team works closely with you throughout the process, adapting your care as needed to support both immediate progress and long-term outcomes.
Explore Your Treatment Options
If you or a loved one has been diagnosed with colorectal cancer, our team is here to help you understand your options and take the next step with confidence.
Colostomy
Sometimes, a person with rectal cancer may need to have a colostomy. This is a surgical opening, or stoma, through which the colon is connected to the abdominal surface to provide a pathway for waste to exit the body. This waste is collected in a pouch worn by the patient. Sometimes, the colostomy is only temporary to allow the rectum to heal, but it may be permanent.
Radiation
For rectal cancer, radiation therapy may be used before surgery, called neoadjuvant therapy, to shrink the tumor so that it is easier to remove. It may also be used after surgery to destroy any remaining cancer cells, chemotherapy is often given at the same time as radiation therapy, called chemoradiation therapy, to increase the effectiveness of the radiation therapy.
Systemic Therapy
Systemic therapy is the use of medication to destroy cancer cells. This type of medication is given through the bloodstream to reach cancer cells throughout the body. Systemic therapies are generally prescribed by a medical oncologist common way to give systemic therapies include an intravenous (IV) tube placed into a vein using a needle or in a pill or capsule that is swallowed (orally).
The types of systemic therapies used for colorectal cancer include:
- Chemotherapy
- Targeted therapy
Immunotherapy / Cellular therapy
As populations of useful bacteria decline over time, bowel-specific immunity and general immune system function deteriorate. The immune system’s overall ability to fight infection and cancer wanes, while inappropriate immune responses, including excessive inflammation, increase. CT can both boost appropriate infection- and cancer-fighting immune functions, and also help to suppress the inflammatory response when it gets out of control.
Autologous cancer vaccines have been studied extensively, with the most encouraging results noted in randomized, controlled clinical trials including more than 1,300 colorectal cancer patients in which tumor vaccines were given after surgery. These trials reported reduced recurrence rates and improved survival.
Hyperthermia
Hyperthermia involves the use of heat to directly treat a tumor or increase the vulnerability of cancer cells to other forms of treatment, such as immunotherapy, vitamin C, chemotherapy or radiotherapy.
On one study colon adenocarcinoma cells demonstrated a promising decrease in cell viability after treatment with the low dose chemotherapy and heat.
Another study confirmed a potent anti-tumor efficacy caused combined thermo-chemotherapy.
Ozone/ Oxygen therapies
Ozone therapy is an effective medical treatment for different diseases like mucositis, psoriasis, acute pain, neurovascular diseases, and cancer.
Studies have shown that ozone could be useful in colon cancer management in combination with nutraceuticals or LDQT w/ 5-fluorouracil and cisplatin with significant inhibition of cytokines having a central role in colon cancer cell survival and chemoresistance.
B Complex
Comprehensive studies have linked a high intake of dietary or supplemental Folate and high blood Folate levels with a reduced risk of colon cancer. Folate and vitamin B12 deficiency is associated with depletion of the major intracellular antioxidant glutathione, and oxidative stress is emerging as an etiological mechanism for colon cancer.
Folate and vitamin B12 supplementation decreased the level of oxidative stress and ameliorated the cytotoxic effects of chemotherapy. Also Folate and vitamin B12 supplementation combats carcinogen-induced oxidative stress.
Selenium
An essential trace mineral, selenium is one of the most important cancer-fighting nutrients. Scientists have noted a statistically significant correlation between low soil concentrations of selenium and increased rates of colorectal cancer.
Selenium supplementation at the time of cancer surgery can increase local immune function, an effect that may reduce recurrence. There may also be synergistic effects of selenium with other nutrients, such as Folate.
A clinical trial of 200 mcg of selenium versus placebo found that the incidence of colorectal cancer was significantly less in those taking selenium.
Curcumin
Curcumin is a powerful anti-inflammatory compound that acts on NF-kB, a proinflammatory mediator that influences hundreds of genes involved in the growth and spread of cancer. In addition, Curcumin regulates tumor suppressor pathways and triggers mitochondrial-mediated death in cancer cells.
It also helps to starve tumors of their vital blood supply and it can oppose many of the processes that permit metastases to spread.
Omega 3 fatty acids
O3FA works in different pathways to combat and prevent colon cancer. Multiple studies show that populations with a higher intake have a lower risk of developing colon cancer.
O3FA reduces the pro-tumor effects of many molecules involved in the growth and spread of colon cancer, including vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), platelet-derived endothelial cell growth factor (PDECGF), cyclo-oxygenase 2 (COX-2), prostaglandin-E2 (PGE2), nitric oxide, NF-kB, matrix metalloproteinases, and beta-catenin. Experiments have shown EPA and DHA can make cancer cells more vulnerable to damage from nutraceuticals, immunotherapy, chemotherapy, and radiation, thus encouraging the cells to turn on cell death pathways in lieu of repair pathways.
Diseases Treated at Integrative Immunotherapy Institute
Questions? We've got answers.
How do you handle complications or side effects?
Patients are monitored daily during treatment. Side effects are tracked, documented, and addressed in real time; sometimes with medication adjustments, sometimes with supportive therapy, occasionally by pausing a treatment. The treating physician reviews the patient's status every day the patient is on-site.
Can I continue treatments I'm already on at home?
Usually yes, but it depends on the specific medication and how it interacts with our protocol. Bring a complete medication list to the consultation. We coordinate with your home physician where possible.
Will my treatment plan change while I'm here?
Sometimes. Blood work, imaging, and response markers are checked during your stay, and the protocol is adjusted if the data suggests it should be. Any meaningful change is reviewed with you before it's implemented.
How is my treatment plan decided?
After we receive your medical records, imaging, and pathology, your case is reviewed by the medical board. They draft a proposed protocol, which therapies, in what sequence, over how many days. You then have a consultation with the treating physician to review it, ask questions, and adjust before anything begins.
Do you offer CAR-T therapy?
Yes, we offer CAR-T therapy in addition to our broader autologous immunotherapy program. Both are built on the same core principle; collecting the patient's own immune cells, engineering or activating them to better recognize cancer, and reinfusing them to do the work. The specifics of which approach fits your case, and how it's delivered, are reviewed during the medical consultation.
What supportive therapies do you offer?
IV vitamin C, ozone therapy, hyperbaric oxygen, peptide therapy, IV nutrition, metabolic support, lymphatic therapy, and others, selected based on the patient's case, not applied as a fixed menu. These are supportive, not curative; they're used to help the body tolerate and respond to the core treatment.
Do you use radiation?
Radiation is not delivered on-site. When radiation is part of the recommended plan, we coordinate with established radiation oncology centers and incorporate it into the broader protocol.
Do you use chemotherapy?
We do, when it's the right tool for a given case, and we say so clearly. For some cancers, low-dose or fractionated chemotherapy combined with immunotherapy is more effective than immunotherapy alone. We don't reject chemo as a category; we use it strategically and at the lowest effective dose.
Do you only treat late-stage or terminal patients?
No. We see patients at every stage, newly diagnosed, in active treatment elsewhere, in remission and looking to lower recurrence risk, and patients who have exhausted conventional options. The protocol is adjusted to the situation.
How does diet affect my immune system?
Our immune system is our army, responsible for protecting us from any possible threat, internal or external. Our food supply is full of chemicals more now than ever, to create shelf life and to preserve the quality of the product, and to avoid contamination, yet it is not related to nutrient lifespan. We now know that food can trigger inflammation and alter our digestive processes, potentially leading to severe dysfunction and disease.
Why are supplements part of the Institute nutritional plan?
Supplements are a main part of a healthy diet regimen. We offer a more specialized line of supplements to our patients designed for them. Our medical team takes into consideration your medical history, lab work, specific medical tests, genetics, physical state, lifestyle, age, gender and type of disease.
Your supplements are reviewed and altered with time as our patients heal and their body finds the balance it needs.
What are the characteristics of the Institute nutrition plan?
Our nutritional plan is:
- Chemical and preservatives free.
- Organic fruit and vegetables.
- Hormone free meat.
- Personalized supplements.
- Metal and mercury free fish.
- Hypo allergenic.
- Gluten and diary free to promote immune tolerance.
- Alkaline to optimize the internal environment to fight and overcome cancer.
How do you create my nutrition plan?
Your personalized nutritional plan is developed, reviewed and redefined by our specialized medical team with our clinical nutritionist, kitchen staff and functional trained chefs.
They take into consideration your unique needs in a stressful situation, nutritional deficiencies, the nutritive food you desperately need, allergies and personal preference of taste and food appearance.
What is the main difference between Enhanced Low Dose Chemo vs conventional chemotherapy?
At the immunotherapy Institute, we use a proprietary method called “Enhanced Low Dose Chemotherapy”, this is a metabolic-supported low dose chemotherapy.
“Enhanced Low Dose Chemotherapy” targets a cell and changes its composition.
First, it attacks the cancer cell through its internal environment and then via the external environment by “prepping” the cancer cell so it becomes more vulnerable to treatment.
In more simple words, “Enhanced Low Dose Chemotherapy” is just a fraction of the normal dose and it only goes after the cancer cells instead of your whole body, which reduces or eliminates the horrible side-effects of conventional chemo.
What kind of hyperthermia do you offer?
There are two types, regional and systemic.
Regional refers to the increase of temperature of a single zone or area.
Systemic is whole-body hyperthermia, which refers to the increase in temperature to hyperthermic levels over the entire body.
Hyperthermia is proven to enhance the effect of anti-cancer treatments like immunotherapy and conventional treatments such as chemo or radiation.
Positive trials have established hyperthermia, in combination with anti-cancer drugs, as a breakthrough cancer treatment.
Hyperthermia doesn’t have any side effects.
Another thing you might wonder is, How long will each session be?
We see great outcomes with 2 to 4 hour-long sessions.
What are the benefits of the hyperthermia we use at our center?
It’s fast acting. You’ll feel results within the first couple of sessions.
You’ll be alert, you won’t have to go through sedation and anesthesia.
You won’t experience any discomfort, which allows for a much larger period, and hence, achieves in a single session, what would take us up to 8 sessions to achieve with other methods.
What is the difference between the Immunotherapy offered through your program and what my doctors are recommending at home?
There are two main types of immunotherapy, chemical, and autologous immunotherapy; we have seen great success with the latter.
In the autologous cellular immunotherapy process, we collect your immune cells and infuse them back into your body after culture.
In the process we activate the anti-tumor response and “train these cells” to effectively target and attack cancer cells.
Autologous Cellular Immunotherapy is made out of specific types of cells mainly Dendritic, NK cells and T lymphocytes.
These cells act against the cancer cells and recharge the immune system.
When they find a tumor cell, the NK and T cells bind themselves to its membrane and inject toxins which kill the cancer cell.
In less than five minutes, the cancer cell dies and the NK and T cells move on to their next target.
Every single case has different specifications, which is why its so important to explore your unique situation.
To find out if this is the right therapy for you, please contact us via phone or Facebook.
What are the side effects of cancer treatment?
Because our program employs natural treatments that only enhance the body’s own natural ability to attack cancer, there’s no negative side-effects. Patients who have previously undergone chemotherapy will be administered a chemo-preconditioning program that will decrease the negative side-effects like, such as hair loss, nausea, toxicity, anemia, and others, until the body is in optimal condition for our treatment program.
What is the probability of curing my cancer?
Unfortunately there’s no guarantees, however our statistical studies have shown that if admitted into our program, there’s a very high chance that the patient will have a positive outcome, in fact on average, 80% of our cancer patients have managed to control their cancer into a manageable state that allows them to gain quality-of-life and avoid the major set-backs known to most cancer patients, or in many cases have completely cured their cancer. Please talk to our doctors so that they can assess your situation and provide a better idea of your possibilities.
Can I undergo treatment at the Institute if I've undergone chemotherapy?
Yes, many of our patients are still doing chemotherapy or have had it done in the past. One of the great benefits of our treatments is that it doesn’t affect being in chemo like most other treatments, in fact, many of our most successful cases have already done chemo in the past. Our treatments will precondition the body to eliminate the toxic effects from previous chemotherapy to get the body to its optimal condition for the treatment.
Can the Institute treat Stage IV cancer?
Yes, in fact, over half of cancer patients are stage IV and although each patient’s outcome is different based on their current health situation, medical history, eating habits, and overall lifestyle, our studies have shown that 90% of our cancer patients have benefited from our treatments. It’s very important that patients in stage 4 make timely decisions because time is of the essence for the treatment to take a positive effect.
