Types of Prostate Cancer
There are several types of prostate tumors, arising from different areas of the prostate that can occur alone or in conjunction with another type. Adenocarcinoma is the most common type, comprising 95% of all prostate cancers.
The remaining 5% of cases of prostate cancer include:
Squamous Cell Carcinoma - These account for 0.5-1% of cases of prostate cancer.
Signet-Ring Carcinoma - This is a very rare and aggressive form of prostate cancer.
Transitional Carcinoma - This type is also rare, and must be distinguished from a primary bladder cancer that has invaded into the prostate - a far more frequent condition.
Neuroendocrine Carcinoma - This is an uncommon cancer that arises from a specialized cell in the prostate gland called neuroendocrine. Some of theses cancers are referred to as small cell cancer.
Sarcoma - This type accounts for only 0.1-0.2% of prostate cancers.
