Melatonin is a hormone that is produced in the brain and controls the day-night rhythm of humans.

Melatonin can inhibit the growth of cancer cells by inhibiting tumor vessels and thus slowing the supply of oxygen and nutrients to cancer cells.

Melatonin also activates a type of suicide program in cancer cells. The program is usually present in all cells and is activated when they become too old or sick.
In cancer cells, the suicide program is typically deactivated. Melatonin reactivates the program, and as a result, the cancer cells die.

Melatonin also inhibits the metastasis and growth of cancer cells into nearby healthy tissue.

In breast cancer, melatonin additionally inhibits growth through its anti-estrogen effects. Estrogen is considered a growth factor in certain types of breast cancer.

Melatonin can also be used excellently for cancer prevention.

Studies have shown the influence of melatonin on the following types of cancer: Breast cancer, ovarian cancer, uterine cancer, mouth cancer, liver cancer, kidney cancer, lung cancer, stomach cancer, pancreatic cancer, colon cancer, and melanoma.

There are many reasons to use melatonin in cancer therapy. It is well-tolerated with no severe side effects.
