Testicular cancer is rare. Cancer usually affects only one testicle, and the chances of a cure are very high, especially if detected in the early stages.

Testicular cancer is diagnosed in most men by doing a testicular self-examination.

Testicular cancer signs:

• A lump or enlargement in any of the testicles
• Feeling of heaviness in the scrotum
• Pain in the lower abdomen and upper thigh
• Sudden accumulation of fluid in the scrotum
• Pain or discomfort in one of the testicles or the scrotum
• Enlarged or sore breasts
• Backache

The causes of testicular cancer are not entirely clear, but many factors may increase the risk of testicular cancer, such as the following:

• Pseudo-cryptorchidism: where the testicle is in the abdominal area instead of being inside the scrotum.
• Klinefelter syndrome: It is a genetic disease that affects men and causes some problems, such as low sperm count, and some endocrine disorders.
• Hereditary family history: where one of the family members has had testicular cancer.
