Prostate Cancer Types

There are many types of prostate cancer and the condition is often present in many different parts of the prostate. The precursor to prostate cancer is known as prostatic intraepithelial neoplasia, this is also found in many different locations within the prostate.

Although there are many different kinds of prostate cancer the vast majority (around 95%) are of the type known as adenocarcinoma. As this is the most wide spread from it has become synonymous with the term prostrate cancer.

Adenocarcinoma

The most common site of origin of prostate cancer is in the peripheral zone (the main glandular zone of the prostate). The term adenocarcinoma can be split up to derive its meaning. Adeno means ‘pertaining to a gland’, whilst Carcinoma relates to a cancer that develops in epithelial cells. The term epithelial simply relates to cells that surround body organs or glands. aldara and basal cell carcinoma

Small cell carcinoma

This kind of cancer is made up of small round cells, and typically forms at nerve cells. Small cell carcinoma is very aggressive in nature and as it does not lead to an increase in prostate specific antigens it can be somewhat harder to detect than adenocarcinoma; this usually means that it has reached an advanced form upon detection.

Squamous cell carcinoma

This is a non glandular cancer, like small cell carcinoma there is no increase in prostate specific antigens when this is present. Squamous cell carcinoma is very aggressive in nature.

There are other, more rare, forms of prostate cancer these include sarcomas and transitional cell carcinoma; the latter rarely develops in the prostate but derives from primary tumours present in the bladder or urethra.
