We have a pharmaceutical industry that pursues profits over people's health. Chemotherapy is very aggressive and weakens people's immune systems, compromising their health.

Chemotherapy destroys the immune system and does not destroy cancer stem cells (CSCs). The truth is that when a person has cancer, it also destroys cancer stem cells (CSCs), which are resistant to chemotherapy. However, immunotherapy can help fight these stem cells in some cases by boosting a person's natural killer (NK) cells. However, it is prescribed less often due to its higher cost and side effects. NK cells, or Natural Killer cells, are immune cells with small particles containing enzymes capable of eliminating tumor cells or cells infected by viruses.

Recent studies lead us to believe that increasing NK cell production will increase immune defense responses to eliminate cancer cells or infected cells and improve overall health. For example, the use of probiotics has shown results of potentially increasing NK cell counts.

My doctoral thesis advisor had prostate cancer, and after 6 years, it had metastasized to the bones. I know of many other cases. A friend of my wife's with stage 3 lung cancer was treated with chemotherapy and immunotherapy. She then had a CT scan and appeared cured. However, she had metastases a few years later.

Other colleagues with advanced stomach and colon cancer also had metastases a few years later. I only know of one friend with stage 2 colon cancer without lymph nodes, who had not undergone chemotherapy, who survived after more than 5 years.

Many articles claim that foods and supplements attack cancer stem cells.

The theory that cancer stem cells (CSCs) initiate and sustain various carcinogenic processes has been validated, and specific methods for identifying CSCs in the entire cancer cell population have also been shown to be effective. The studies provide an overview of recently acquired scientific knowledge regarding phytochemicals and herbal extracts that have been shown to target and kill CSCs. Many genes and proteins that support CSC self-renewal capacity and drug resistance have been described, and applications of phytochemicals capable of interfering with these signaling systems have been shown to be operationally efficient both in vitro and in vivo. Identification of specific surface antigens, mammosphere formation assays, serial colony-forming unit assays, xenograft transplantation, and label retention assays, along with the assessment of aldehyde dehydrogenase 1 (ALDH1) activity, are the most commonly used techniques to measure phytochemical efficiency in killing CSCs. Among dietary chemopreventive agents, the following are the most effective in reducing the proliferative activity of cancer cell lines found in foods: fisetin, quercetin, epigenin, sulfuraphan, and berberine; epigallocatechin-3-gallate; curcumin; resveratrol; lycopene; pomegranate; luteolin; and genistein. These phytochemicals have been thoroughly studied for at least three decades. In fact, research on phytochemicals began even before the potential role of CSCs in tumor development and spread was known. However, these studies provide a wealth of knowledge that can now be applied to the development of CSC treatments.
