Testicular cancer is a malignant tumor formed by cancerous cells in the testicles. As one of the most prevalent cancers in young men, the causes of testicular cancer are not well known, and according to statistics, the incidence of testicular cancer in men is 7 per 100,000 and increasing year by year. Testicular cancer is mainly divided into two categories: spermatogonial cell carcinoma and non-sematogonial cell carcinoma. Spermatogonial cell carcinoma accounts for 30% of all testicular cancers. Non-seminomatous cell cancers include choriocarcinoma, germinoma, teratocarcinoma and yolk sac tumors. In the vast majority of cases, these symptoms are the result of BPH, but prostate cancer can also cause similar symptoms. So when you encounter these troubles, don’t feel embarrassed to go to the hospital; and don’t take it for granted to attribute the cause to prostate enlargement. It is better to go to the urologist first to find the cause. Your doctor will do some tests to determine if you have prostate enlargement and also test your blood for PSA to help diagnose prostate cancer. If you find a new swelling, pain or other abnormalities in your testicles, don’t hesitate to go to the hospital as soon as possible. Unlike prostate cancer, which is slow-growing, testicular cancer deteriorates quickly. With these conditions, doctors will determine the cause of the disease through physical examination, blood test, and ultrasound.
