The word “cancer” refers to the process of uncontrolled cell division but technically it is not in itself the name of a specific disorder. Instead, cancer is an umbrella term that refers to more than one hundred different kinds of diseases, which are generally named according to the area where a tumor first appears.

Almost all the cells in our bodies must be replaced on a regular basis. Some cells, like those that make up the intestinal lining, die out quickly and are replaced every few days. In other parts of the body, the cells live for years before they divide and form new ones. Under special circumstances, such as an injury or illness, healthy new cells may grow more quickly than usual to replace those that are damaged. When the area is healed, the cell growth slows back down to its normal rate.

Normally, the genes that control the growth of cells automatically know when to start and stop the replication process. But when those genes are mutated - perhaps because of an inherited flaw or more commonly because of dietary and environmental factors – cells may begin to multiply and divide at an unusually fast rate. Sometimes cancers are benign(meaning that they are non-cancerous and relatively harmless), as in the case of warts or uterine fibroids.

Other growths, however, are malignant. They pull nutrients away from the healthy tissues that surround them, and they interfere with the body’s normal functions, to a potentially life-threatening extent. If a tumor continues to grow, its cells may spread via the blood vessels or lymphatic system to other parts of the body, where they form new tumors. Once this process, called metastasis, is underway, there is the risk of dying from the complications that can occur. Although many cancers can be treated successfully when caught early, the sad fact remains that they are a leading cause of death in the United States. Every minute, another person dies of some form of the disease.

Dr. Stengler works with people who are under the primary care of an oncologist to provide supportive and complementary treatment. This involves supporting detoxification during chemotherapy and radiation, tissue healing after surgery, immune system enhancement, and general body balancing depending on what weak organ systems are identified.

  • Mary Sweeney - San Diego, CA

    Dr. Mark Stengler saved my life…PERIOD. I was 290 lbs and covered with eczema when I called his office in January 2009. The doctors I went to before discovering Dr. Stengler were top-rated doctors in the fields of dermatology, internal medicine, rheumatology and more. I spent thousands of dollars over and above what my insurance […]

  • Mike Azevedo - Temecula, CA

    I have had sleep problems since I was a teenager. In my early 20s, my doctor sent me to the prestigious Stanford Sleep Clinic. Their recommendation was prescription sleeping pills. I experienced so many adverse side affects that I stopped taking them. Since then I have been to many doctors over the years as not […]

  • Isabella V - San Diego, CA

    It is great working with Dr Stengler. He listened to all my concerns and addressed them all. My hot flashes were gone within a week. I have more energy and a more positive outlook. I’ve been tested borderline thyroid for many years and my primary care doctor did not want to do anything. Dr Stengler […]

  • Patrice Reynolds - Del Mar, CA

    I went to Dr. Stengler to help me with my thyroid and subsequent struggles with depression. He helped me greatly by switching me to a natural thyroid and prescribing a regimen of daily supplements. My thyroid is now balanced and I rarely experience depression. I have also taken my four children to him and they […]

Diet and Proper Supplementation

What you need to know: Cancer is not a single disease, and it can have many different causes. That makes it virtually impossible for any one nutrient to protect against all types of cancer. In fact, studying whether single nutrients reduce the risk for cancer often is like looking for a magic bullet—more wishful thinking than good science. Nothing can absolutely guarantee that you’ll remain cancer-free. However, good nutrition and a healthful overall lifestyle—not smoking, not abusing alcohol, limiting exposure to pollutants, eliminating food additives and controlling stress—can lower your odds of developing cancer.

Intravenous Nutrient Therapy

IV Nutrient Therapy is used to enhance immunity and support energy levels for those undergoing conventional cancer treatments. It is also a great therapy following conventional cancer therapy for regeneration and restoration of health. IV nutrients commonly include vitamin C, B vitamins, amino acids, glutathione, zinc, and other safe nutrients.

There have been a number of studies of interest in this area:
1. Ascorbate Acid Kills Cancer Cells

Pharmacologic ascorbic acid concentrations selectively kill cancer cells: Action as a pro-drug to deliver hydrogen peroxide to tissues. Read Study

2. Ascorbate as Prooxidant Therapeutic Agent in Cancer

Ascorbate in pharmacologic concentrations selectively generates ascorbate radical and hydrogen peroxide in extracellular fluid in vivoRead Study

3. Ascorbic Acid 2008: The Controversial Place of Vitamin C

Recent pharmacokinetic data suggest that pharmacologic concentrations of vitamin C can be achieved by intravenous injections. Since these concentrations exhibit anticancer activities in vitro, this raises the controversial question of the re-evaluation of vitamin C in cancer treatment. Therefore, the purpose of this commentary is to make a critical review of our current knowledge of vitamin C, focusing on the rationale that could support its use in cancer therapy. Read Study

4. Ascorbic Acid and Cancer – 25 Years Later

New knowledge on the pharmacokinetics and pharmacodynamics of Ascorbic Acid (AA) and new clinical data have given a more complete understanding of the critical aspects of AA’s therapeutic effect on cancer. Read Study/p>

5. Intravenous Ascorbate as Chemotherapeutic Agent

For over 15 years we have studied high dose intravenous ascorbic acid (IAA) as an adjunctive therapy for cancer patients. Initially, doses of 15g per infusion were used, once or twice per week. These doses improved patients’ sense of well being, reduced pain, and in many cases prolonged life beyond prognostications of oncologists.
Twelve years ago, we used infusions of 30 grams of IAA, twice per week, and found that metastatic lesions in the lung and liver of a man with a primary renal cell carcinoma disappeared in a matter of weeks… Read Study.
6. Intravenous Ascorbate as Tumor Cytotoxic Chemotherapeutic Agent

Abstract — Ascorbic acid and its salts (AA) are preferentially toxic to tumor cells in vitro and in vivo. Given in high enough doses to maintain plasma concentrations above levels that have been shown to be toxic to tumor cells in vitro, AA has the potential to selectively kill tumor cells in a manner similar to other tumor cytotoxic chemotherapeutic agents. Most studies of AA and cancer to date have not utilized high enough doses of AA to maintain tumor cytotoxic plasma concentrations of AA. Data are presented which demonstrate the ability to sustain plasma levels of AA in humans above levels which are toxic to tumor cells in vitro and suggests the feasibility of using AA as a cytotoxic chemotherapeutic agent. Read Study.

Coriolus enhances disease-free period after colon cancer surgery

A ten year, randomized double-blind trial was performed by administering Coriolus (PSK) to 56 patients and a placebo to another group of 55 patients after surgical operations on their colorectal cancers. The rate of patients in remission (or disease-free) was significantly higher (more than doubled) in the PSK group than in the placebo group. Researchers also found the white blood cells showed “remarkable enhancement in their activities.”

Maitake Cancer Study

A total of thirty-three cancer patients in stages II, III, and IV, ages thirty-three to sixty-eight, participated in this trial. Data was collected under the cooperation of their medical doctors in Japan. Patients were given either MD fraction with tablets only, or MD fraction and tablets in addition to chemotherapy. Cancer regression or significant symptom improvement was observed in eleven out of sixteen breast cancer patients, seven out of twelve liver cancer patients, and five out of eight lung cancer patients.
