It can tighten and Prostate purpose restrict the flow of urine through the urethra using thousands of tiny muscle fibers. Tiny changes occur in the shape and size of the prostate gland cells, known as prostatic intraepithelial neoplasia (PIN). This tends to happen slowly and does not show symptoms until further into the progression. Nearly 50 percent of all men over the age of Prostate purpose 50 years have PIN. High-grade PIN is considered pre-cancerous, and it requires further investigation. Prostate cancer can be successfully treated if it is diagnosed before metastasis, but if it spreads, it is more dangerous. Stages Staging takes into account The size and extent of the tumor and the scale of the metastasis (whether it has traveled to other organs and tissues).
At Stage 0, the tumor has prostate purpose neither spread from the prostate gland nor invaded deeply into it. At Stage 4, the cancer has spread to distant sites and Prostate purpose organs. Diagnosis A doctor will carry out prostate purpose a physical examination and enquire about any ongoing medical history. If the patient has symptoms, Prostate purpose or if a routine blood test shows abnormally high PSA levels, further examinations may be requested. Imaging scans can show and track the presence Prostate 4 finger breadth of prostate cancer. Imaging scans can show and track The presence of Prostate cancer.
Tests may include: a digital rectal Prostate purpose examination (DRE), in which a doctor will manually check for any abnormalities of the Prostate purpose prostate with their finger a biomarker test checking prostate purpose Prostate purpose the blood, urine, or body tissues of a person with cancer for chemicals unique to prostate purpose Prostate purpose individuals with cancer If these tests show abnormal results, further tests will include: a PCA3 test examining the urine for the PCA3 Prostate purpose gene only found in prostate cancer cells a transrectal ultrasound scan providing imaging of prostate purpose the affected region using a probe that emits sounds a biopsy, or the removal of 12 to 14 small pieces of tissue from several areas of the prostate for examination under a microscope These will help confirm the stage of the cancer, whether it has spread, and what treatment is appropriate. To track any spread, or metastasis, doctors may prostate purpose use a bone, CT scan, or MRI Prostate purpose scan. Outlook If the disease is found before it spreads to other organs in a process known as metastasis, the 5-year survival Prostate purpose rate is 99 percent. Once the cancer metastasizes, or spreads, the 5-year survival rate is 29 percent. Regular screening can help detect prostate prostate purpose cancer while it is still treatable. Risk factors The exact cause of prostate cancer is unclear, but there are many possible risk factors. Age Prostate cancer is rare among men under the age of 45 years, but more common after the age of 50 years. Geography Prostate cancer occurs Most frequently Prostate purpose in North America, northwestern Europe, on the Caribbean islands, and in Australia. Genetic factors Certain genetic and ethnic groups have an increased risk of prostate cancer. In the U. prostate purpose S., prostate cancer is at least 60 percent more common and 2 to 3 times more deadly among black men than non-Hispanic white men. A man also has a much higher risk of developing cancer if his identical twin has it, and a man whose brother or father had prostate cancer has twice the risk of developing it compared prostate purpose to other men. Having a brother who has Prostate purpose or has had prostate cancer is more of a genetic risk than having a father with the disease. Diet Studies have suggested that a diet high in red meat Prostate flush or high-fat dairy products may increase a person's chances of developing prostate cancer, but the link is neither confirmed nor clear.
Medication prostate purpose Some research has suggested that non-steroidal anti-inflammatory drug (NSAID) use may reduce the risk of prostate cancer. Others have linked NSAID Prostate purpose use with a higher risk of death from the disease. This is a controversial area, and results have not been confirmed. There has also been some investigation into whether statins might slow the progression of prostate cancer.
One Prostate purpose 2016 study concluded that results were "weak and inconsistent." Obesity It is often prostate purpose believed that obesity is linked to the development of prostate cancer, but the American Cancer Society maintains that there is no clear link.
