As many prostate tumor patients do not have obvious clinical symptoms at first, it is difficult to attract early attention. Some prostate patients are found to have bone metastases or compression of the urethra causing a series of urinary symptoms, which seriously affects the quality of life. The actual fact is that you can find out more about prostate tumor through what methods? 1. Rectal finger examination: Commonly speaking, the doctor’s index finger can touch the prostate gland to detect many patients with asymptomatic prostate cancer, which is the simplest, most economical and practical method in clinical practice. Under normal circumstances, the size of the prostate gland is about 4*3*2cm, with a soft texture and smooth surface without nodular sensation. In contrast, in patients with prostate cancer, hard nodules can often be felt, and even the entire hardened prostate can be felt. If this is the case, then prostate cancer should be suspected and the diagnosis should be confirmed by further prostate puncture biopsy. Therefore, the most routine and effective method must not be neglected during the usual medical checkup. 2.Serum PSA: It is the abbreviation of anterior tear gland specific antigen. Under normal circumstances, PSA in blood is less than 4ng/ml, which is also the most sensitive indicator for screening prostate cancer recognized worldwide at present. The PSA can also be detected in normal people, but its value is not greater than 4ng/ml. some operations such as prostate massage, cystoscopy, catheterization, transrectal ultrasound, prostate puncture biopsy and transurethral resection of the prostate can cause an increase in PSA at night, but it will not be consistently high or remain high. If the PSA indicator is found to be elevated during the physical examination, it should be reviewed on different days. If it is still elevated, and if inflammation or other influencing factors are ruled out, it is possible that prostate cancer may be present and a prostate puncture biopsy should be performed. Of course, some prostate cancer patients have PSA indicators that are not necessarily higher than 4ng/ml. For those patients with PSA indicators that are not high but have prostate cancer symptoms, they need to have their PSA checked regularly and undergo rectal examinations and ultrasound to avoid delaying the diagnosis and treatment. 3. Transrectal ultrasound (TURS): The ultrasound probe is inserted into the patient’s rectum to probe the prostate, which can also detect prostate nodules, but some patients may experience slight discomfort. This is because there are some prostate nodules that are not always palpable through the doctor’s rectal exam. Transrectal ultrasound, on the other hand, has a high sensitivity for probing the prostate and detecting abnormal echogenic nodules in the prostate. However, it is important to note that this test has an elevated effect on serum PSA, so it should be performed after a blood draw. Of course, the final diagnosis of prostate cancer still depends on pathology. In other words, if any abnormalities are found by the above methods: hard nodes or hardening of the prostate on rectal finger examination, elevated PSA or suspicious lesions on ultrasound examination, you should undergo transrectal prostate puncture biopsy. We recommend that men over the age of 50 should routinely see a specialist for an annual prostate examination, including rectal finger examination, serum PSA test and transrectal endoluminal ultrasound, for early detection of prostate cancer.
