The protein excreted Prostate 5lx by the prostate, prostate-specific antigen (PSA), helps semen retain its liquid state. An excess of this protein in the blood is one of the first signs of prostate cancer. The urethra is tube through which sperm and urine exit the body. As such, the prostate is also responsible for Prostate 5lx urine control. It can tighten and restrict the flow of urine through prostate 5lx the urethra using thousands of tiny muscle fibers. Tiny changes occur in the prostate 5lx shape and size 1 prostate cancer of the prostate gland cells, known as prostatic intraepithelial prostate 5lx Prostate 5lx 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 50 years have PIN.
High-grade PIN is considered pre-cancerous, and it requires further investigation. Prostate cancer can be successfully treated if it Prostate 5lx is diagnosed before metastasis, but if it spreads, it is more dangerous. Stages Staging takes into account the size and extent of the tumor prostate 5lx and the scale of the metastasis (whether it has traveled to other organs and tissues). At Stage 0, prostate 5lx the tumor has neither spread from the prostate gland nor invaded deeply into Prostate 5lx it. At Stage 4, the cancer has spread to distant sites and organs. Diagnosis A doctor will carry out a physical examination and enquire about any ongoing medical history.
If the patient has symptoms, or if a routine blood test shows abnormally high PSA levels, further examinations may be requested. Imaging scans can show and track the presence of prostate cancer.
Imaging scans can show and track the presence of prostate cancer. Tests may include: a digital rectal examination (DRE), in which a doctor will Prostate 5lx manually check for any abnormalities of the prostate with their finger a biomarker test checking the blood, urine, or body tissues of a person prostate 5lx with cancer for chemicals unique to individuals with cancer If these tests show abnormal results, further tests will include: a PCA3 test examining the urine prostate 5lx for the PCA3 gene only found prostate 5lx in prostate cancer cells a transrectal ultrasound scan providing Imaging of the affected region using a probe that prostate 5lx emits sounds a biopsy, or the removal of 12 to 14 small Prostate 5lx pieces of tissue from several areas Prostate 5lx prostate 5lx 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 use a bone, CT scan, or MRI scan.
Outlook If the disease is found before it spreads to other organs in prostate 5lx prostate 5lx a process Prostate ultrasound known as metastasis, the 5-year survival rate is 99 percent. Once the cancer metastasizes, or spreads, the 5-year survival rate is 29 percent. Regular prostprostate 5lx ate 5lx screening can help detect prostate 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, Prostate 5lx but more common after the age of prostate 5lx 50 years. Geography Prostate cancer occurs most frequently in North America, northwestern Europe, on the Caribbean islands, and Prostate 5lx in Australia. Genetic factors Certain genetic and ethnic groups have an increased risk of prostate cancer. In the U. S., prostate cancer is at Prostate 5lx least 60 percent more common and 2 to 3 times more deadly prostate 5lx among black men than non-Hispanic white men.
