Prostate cancer is the most common cancer among men (after skin cancer), but it can often be treated successfully.
- Benign tumors: These are not cancerous, and usually they are not a threat to life. They don’t invade the tissue around them and once they are treated or removed, they usually don’t grow back.
- Malignant tumors: These are cancerous growths. Although they usually can be removed, they can also grow back.
There are several types of cells in the prostate, but almost all prostate cancers develop from gland cells. This type of cancer is called adenocarcinoma. Prostate cancer cells can spread through the lymph nodes and blood vessels to other parts of the body. When this happens, the cancer has metastasized and new tumors may form in those parts of the body.
