By Mayo Clinic Staff. Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide.
Prostate cancer means that cancer cells form in the tissues of the prostate. Prostate cancer tends to grow slowly compared with most other cancers. Cell changes may begin 10, 20, or even 30 years before a tumor gets big enough to cause symptoms. Eventually, cancer cells may spread (metastasize).
