Abnormal tissue that appears as a hypoechoic lesion indistinguishable from carcinoma.
PIN. Noncancerous growth of the cells lining the internal and external surfaces of the prostate gland. It is an important sign that prostate cancer may develop.
Suspicious†prostate cells, that is, cells that are not clearly cancerous but are not quite normal, either. These are classified as and can be either low-grade or high-grade. Low-grade PIN does not necessarily lead to prostate cancer. High-grade PIN carries a 30 to 50 percent chance of developing into prostate cancer.
A proliferative lesion composed of prostatic epithelial cells that are dividing more rapidly than normal epithelium. Although the cells have not yet become cancerous, PIN is believed to be the most likely precursor of prostate cancer. For example, up to 80% of patients who are identified to have PIN from a biopsy progress to cancer.
possibly pre-malignant state of tumour cells within the prostate associated with a higher risk of developing invasive disease.
A precancerous lesion of the prostate that often accompanies prostatic cancer.
a condition in which there are changes in the microscopic appearance of prostate epithelial cells. The condition may lead to the development of prostate cancer.
Prostatic intraepithelial neoplasia (PIN) is a precancerous lesion in the prostate gland which is a precursor of http://www.malecare.com [prostate cancer]. Microscopically, PIN is a collection of irregular cells which are fully contained within the gland structure and have not spread to the surrounding tissue. This may be proven by the identification of basal cells forming the supporting layer of the gland.
