"testicular cancer"の定義と意味

What is "testicular cancer"?

Testicular cancer is a type of cancer that begins in the testicles, which are the male reproductive organs that produce sperm and hormones. It usually affects young or middle-aged men, typically between the ages of 15 and 35. Symptoms of testicular cancer may include a lump or swelling in one of the testicles, a feeling of heaviness or discomfort in the scrotum, which is the pouch of skin that holds the testicles, pain or discomfort in the testicle or scrotum, and a dull pain in the lower abdomen or pelvic area. Risk factors for testicular cancer include undescended testicles, family history of the disease, and certain genetic conditions. Treatment options for testicular cancer depend on factors such as the type and stage of cancer, but may include surgery to remove the affected testicle, radiation therapy, chemotherapy, or surveillance. Early detection and immediate treatment can lead to high cure rates for testicular cancer.
