Cancer starts with one cell. Cancer is when that cell reproduces itself uncontrollably, and that usually starts many years before you can feel a lump, or a doctor can see it on a scan.

Observing the differences between normal cells and cancer cells, the cancer cell seems to have lost a number of vital control systems. What happens is that some of the genes in the cell have been damaged or lost. This is called mutation.

A healthy immune system destroys cancer cells

A healthy immune system can destroy 10,000 cancer cells every day. A weak immune system has a difficult time destroying these mutant cells. If your defense against these cancerous cells fails, the cancer multiplies and becomes a clinical case of cancer.

Eventually these multiplying cells form a visible mass or tumor. This initial tumor is called the primary tumor. Cells from the primary tumor sometimes break off and lodge elsewhere in the body where they then grow into secondary tumors. This process is called metastasis. When cancer spreads to another organ, the type of cancer remains the type of the primary tumor. Thus cancer that started in the colon and spread to the liver is still colon cancer, rather than liver cancer. Breast cancer that has spread to the bone is not bone cancer, but metastatic breast cancer.

Cancer is considered a disease of civilization and is practically unheard of among “primitive” folks who have been fed a simple natural diet, free from artificial additives and preservatives. For instance, the only Eskimos to ever develop cancer were those who came to live in white man’s settlements and adopted their diets.
