Some of the signs of testicular cancer include a painless lump in the testicle, swelling that makes one testicle appear larger than the other, or a dull ache in the scrotum or testicles. GETTY
Testicular cancer occurs when abnormal cells in the testicles begin to divide and grow in an uncontrolled manner. The testicles are two egg-shaped organs located in the scrotum that are responsible for producing sperm and hormones, such as testosterone. If the abnormal cells within the testes are cancerous, they can spread and form tumours that destroy healthy tissue in the surrounding area and metastasize to other areas of the body.
Testicular cancer is rare compared to other cancers, but it is one of the most common forms of the disease diagnosed in young men. Fortunately, this cancer is highly treatable, even if it has already spread to other areas of the body.
