The testicles are part of the male reproductive system. In adult men, each one is normally a little smaller than a golf ball. They are held in a sac of skin called the scrotum. The scrotum hangs beneath the base of the penis. The testicles make the male hormone testosterone. They also make sperm. Sperm cells are carried from the testicles through small tubes (the vas deferens) to the seminal vesicles. (Unknown, 2011) Testicular cancer is a disease in which cells become malignant. When a cell becomes malignant, it becomes cancerous. Testicular cancer can start in one or both testicles. This type of cancer is the most common type of cancer in young men between the ages of 15 and 35. Testicular cancer can be classified into two types: seminoma and nonseminoma. Seminomas make up of 30 percent of all testicular cancers. Nonseminomas are groups of cancers that include choriocarcinoma, embryonic carcinoma, teratoma, and yolk sac tumors. (Emedicine Health, 2013) Testicular cancer may have a combination of both types. Research has not shown a connection between testicular cancer and any particular activities, lifestyle, or habits. There is however, evidence that the risk of testicular cancer is higher in those whose testicles did not descend normally. When a testicle descends normally, it moves from the lower abdomen into the scrotum. If a testicle does not descend normally, surgery is often performed to correct the problem..Although the exact causes of testicular cancer are not known, there are several predisposing factors that may place some men higher risk. Some of them include past medical history of undescended testicle, mumps orchitis, or previous testicular cancer on the other testicle. Frequently, testicular tumors are noted after an episode of trauma; however, trauma is not believed to be a causative or predisposing factor. Testicular cancer is not contagious, no one can catch it form another person. Exactly what cause this disease is unknown and seldom can it...
