What is prostate intraepithelial neoplasia?

prostate, part of the human reproductive system, mostly produces fluid that nourishes sperm. When cells in the prostate are subject to abnormal changes, it often leads to prostate disorders. One of them is known as prostate intraepithelial neoplasia (PIN). This condition is generally considered a precancerous state, which means that it tends to develop on prostate cancer. Prostate cancer is important in older men.

Screening procedures for prostate cancer, such as a blood -specific blood test (PSA) and digital rectal examination (DRE), usually cannot detect the presence of prostate intraepithelial neoplasia. Most men with this condition do not develop symptoms. This abnormality in the gland of the prostate often occurs during biopsy or removal of prostate tissues, due to other reproductive problems such as benign prostate hyperplasia (BPH). BPH usually occurs when the prostate is enlarged. Men often experience frequent urination and interruption of urine flow.

prostate tissue from biopsy is processed in the laboratory and analyzed by a pathologist for the presence of abnormalities. Pathologists are experts in the study of blood and tissues to determine the cause of the disease. When prostate intraepithelial neoplasia is found, it is described as a low or high class, depending on its appearance compared to normal cells. This categorization is also often important in the treatment of patients.

In low degree of prostate intraepithelial neoplasia, the appearance of abnormal cells has only a slight difference from normal prostate. Most urologists, doctors who treat men with reproductive organ disorders, may ask patients to have further control and biopsy a year later. Studies have indicated that A16% of the low degree pin can lead to prostate cancer.

men diagnosed high -quality prostate intraepithelial neoplasia, but are often managed differently. The reasonIt is that abnormalities in cell appearance are usually more pronounced in high quality prostate intraepithelial neoplasia. Patient monitoring is commonly performed every six months, when they can undergo a dog test, DRE and repeated prostate biopsy.

It is estimated that about 30% of men with high -quality prostate intraepithelial neoplasia can be diagnosed with prostate cancer during repeated biopsy. If no cancer is found after the first two years of regular inspection, patients are usually planned to visit once a year. When cancer is found, appropriate treatment is administered.
