Why? Cancers which are detected early are the most easily treated so it makes sense to check your self regularly. It will help you know what is normal for you and enable you detect changes.

When? Regularly; at least once a month. Ideally in the shower/bath when the muscle in the scrotum is relaxed.
How?
• Gently feel each testicle individually. You should feel a soft tube at the top and back of the testicle. This is the epididymis which carries and stores sperm. It may feel slightly tender. Don’t confuse it with an abnormal lump. You should be able to feel the firm, smooth tube of the spermatic cord which runs up from the epididymis.
• Feel the testicle itself. It should be smooth with no lumps or swellings. Ot is unusual to develop cancer in both testicles at the same time, so if you are wondering whether testicle is feeling normal or not you can compare it with the other.
•REMEMBER-if you do notice a change in size/weight or find any abnormal lumps or swellings in your testicle, make an appointment and have it checked as soon as possible.
•Note-most abnormalities are not cancer but collections of fluid, infection or cysts. More than a third of people with this kind of cancer consult their doctor after the cancer has metastasized, which make treatment more difficult. Often this is because of unfounded fears, or just hoping it will go away.
