User:Mr. Ibrahem/Testicular cancer

Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. Symptoms may include a lump in the testicle, or swelling or pain in the scrotum.

Risk factors include an undescended testis, family history of the disease, and previous history of testicular cancer. The most common type (>95%) are germ cell tumors which are divided into seminomas and nonseminomas. Other types include sex-cord stromal tumors and lymphomas. Diagnosis is typically based on a physical exam, ultrasound, and blood tests. Surgical removal of the testicle with examination under a microscope is then done to determine the type.

Testicular cancer is highly treatable and usually curable. Treatment options may include surgery, radiation therapy, chemotherapy, or stem cell transplantation. Even in cases in which cancer has spread widely, chemotherapy offers a cure rate greater than 80%. Treatment may result in infertility.

Globally testicular cancer affected about 686,000 people in 2015. That year it resulted in 9,400 deaths up from 7,000 deaths in 1990. Rates are lower in the developing than the developed world. Onset most commonly occurs in males 15 to 35 years old. The five-year survival rate in the United States is about 95%. Outcomes are better when the disease remains localized.
