Doctors have known that low levels of vitamin D are linked to certain kinds of cancers as well as to diabetes and asthma, but new research also shows that the vitamin can kill human cancer cells.
The vitamin’s effects were even more dramatic on breast cancer cells injected into mice.
After several weeks of treatment, the cancer tumors in the mice shrank by an average of more than 50 percent. Some tumors disappeared. Similar results have been achieved on colon and prostate cancer tumors in mice.
