The exact causes of testicular cancer are unknown. However, several conditions may increase your chances of developing testicular cancer, including:1, 3 undescended testicle (cryptorchidism), which occurs when the testes do not descend from the abdomen into the scrotum. Normally, the testes descend into the scrotum before the male fetus is born or during the first 3 months of infancy. Klinefelter syndrome. Klinefelter syndrome is a genetic disorder that affects males.

Testicular cancer is a disease that occurs when abnormal cells in the testicles (testes) begin to grow in an uncontrolled manner. The testes are the two male sex organs that produce and store sperm . The testes also produce testosterone, a male hormone. They are located in a pouch below the penis called the scrotum. Testicular cancer is most common among white males and is considered uncommon in men of African and Asian descent.

of January 2007, the LAF has discontinued offering grants in the area of basic and clinical science of testicular cancer. 

The exact causes of testicular cancer are unknown. However, several conditions may increase your risk, including:1, 3 Cryptorchidism (undescended testicle), which occurs when the testes do not descend from the abdomen into the scrotum.

Most testicular cancers are detected during a self-examination or during a routine physical exam by a health professional. If your health professional suspects you have testicular cancer, the following tests may be used to help determine the exact nature of your condition. Testicular ultrasound may be used to rule out other possible causes of an enlarged or painful testicle. Ultrasound is a test that uses reflected sound waves to produce an image of organs and other structures in the body.

In the majority of cases, treatment for testicular cancer does not result in long-term sexual side effects or infertility, though it may increase these problems if they are present before treatment begins. Men who have one remaining healthy testicle should not notice any negative change in their quality of life. Some men may choose to have a prosthetic testicle. After orchiectomy, the surgeon places an artificial testicle in the scrotum to maintain the natural appearance of the genitals.

Testicular cancer is the most common form of cancer in young men, mostly between the ages of 20 and 35, although it can develop in boys as young as 15. Incidence has almost doubled in the last twenty years, with about 2,000 cases a year in the UK.

Testicular cancer can be treated by surgery, by radiotherapy or by chemotherapy. In some cases these treatments are combined. The most straightforward and safest way of dealing with a cancerous lump is to remove the testicle.

Several conditions may increase your risk of getting testicular cancer. (Most men who get testicular cancer don't have any risk factors.) These risk factors include:1, 3 undescended testicle (cryptorchidism). This is a testicle that has not descended from the abdomen into the scrotum. Normally, the testes descend into the scrotum before the male fetus is born or during the first 3 months of infancy. Klinefelter syndrome. This is a genetic disorder that affects males.

We are still investigating the causes of testicular cancer and do not know of any treatments that could prevent it. The most important thing is to check your testicles regularly to detect any changes in their shape or size. The most significant risk factor is undescended testis at birth with 10% of patients having a history of this condition.

of testicular cancers can be cured if caught at an early stage. Even when the tumour spreads, the cure rate is around 95%. Treatment may be very intensive, but most patients cured will have no long-term side effects from treatment. A small proportion of patients will become infertile after chemotherapy treatment. Other side effects of treatment are uncommon but may include damage to the nerve endings, hearing and poor circulation.

In the early 1990’s a concern was raised that men who had a vasectomy were at greater risk for getting prostate cancer, a disease that will affect 1 out of 6 American men. This concern sparked great interest and research that concluded that vasectomy is not a risk factor for prostate or testicular cancer or any other disease.

Current risk estimates suggest that 1 out of 3 Americans will develop some type of cancer in their lifetime. This means that 2 out of 3 Americans will not develop cancer.
