The male reproductive system has a small walnut-shaped gland called the prostate responsible for creating the fluid that nourishes and carries sperm. Any abnormal cell growth in this gland can lead to cancer. In the initial stages, prostate cancer patients usually do not experience any visible symptoms. As long as the tumor is confined to the gland, the cancer treatment can be effective. Here are some warning signs of prostate cancer that necessitate prompt diagnosis. Early warning signs of prostate cancer Prostate cancer develops slowly and is largely asymptomatic, but those in more advanced stages may experience the below symptoms. Bladder issues The prostate gland is located close to the bladder and urethra, so one may experience symptoms affecting urination. A common sign of prostate cancer is a constant or frequent urge to empty one’s bladder. One may also experience a burning sensation, pain, or difficulty stopping while urinating. Other changes one may notice include blood in the urine or the flow being too weak. Fatigue and nausea Studies indicate that cancerous cells consume over 20 times more glucose than normal cells. This large amount of energy intake may lead to losing body mass or feeling tired and nauseous without any lifestyle changes.
