The incidence of prostate cancer in men is on the rise, and in economically developed regions such as North, Shanghai and Guangzhou, the incidence of prostate cancer has even surpassed bladder and kidney cancer, ranking first in the incidence of urological tumors. Men should be alert to the occurrence of prostate cancer after the age of sixty, especially older men with a family history of the disease. A common screening indicator for prostate cancer during outpatient urology exams is the prostate-specific antigen (PSA). If the test result is above 4ng/ml, it is recommended to see a specialist for rectal examination to find out the size, texture and nodules of the prostate gland, and a transrectal ultrasound can be done. This is an ultrasound probe that goes through the rectum to look at the prostate, which can be a little uncomfortable. If the rectal ultrasound suggests hypoechoic nodules around the periphery of the prostate, it must be taken seriously, and this often suggests the occurrence of prostate cancer, which requires an appointment with a prostate MRI for further examination to visualize the site of the tumor, its size, the extent of infiltration, and whether it invades surrounding organs. After these examinations are completed a puncture biopsy must be performed to confirm the prostate cancer and the pathological diagnosis is the final confirmation of the diagnosis! In conclusion, if prostate cancer is suspected, initial screening by PSA, then further examination by rectal ultrasound and prostate MRI, and finally confirmation by puncture biopsy are required!
