Almost all prostate cancers develop from the cells that line the prostate gland – this type of cancer is called an adenocarcinoma.
Other types of cells in the prostate can also develop into prostate cancer. These cancers are called:
- small cell carcinomas
- neuroendocrine tumours or transitional cell carcinomas
These are all extremely rare.
