The one thing to be avoided is taking too much selenium, as it can be poisonous. When taking it as a dietary supplement, never exceed 200 micrograms per day. Dear Dr Matfield, I have been reading your newsletter for many years now with great interest. However, at no time have I seen any reference to adenocarcinoma, the type of cancer which killed my late wife. It is describing a common sub-type of cancer.
Most human cancers are a type called carcinomas.
We get carcinoma of the lung, carcinoma of the breast, carcinoma of the bowel and so on. Each one is a different cancer, which needs to be treated differently. When a tissue sample from a carcinoma is examined under the microscope, the cells are often seen to have grown in a certain pattern, such as the pattern of cells found under the skin. When the pattern of cells looks like that normally found in glandular tissue, the cancer is called an adenocarcinoma. Cancer of the kidney, ovary and lung are often adenocarcinomas.
