Testicular cancer has one of the highest cure rates of all cancers: in excess of 90% if caught in time.
Testicular Cancer: Male Health Scotland
The Testicles produce sperm and testosterone. Men have two Testicles, which are contained within an extension of the abdomen called the Scrotum.
Testicular Cancer develops most frequently in males aged from 15-40 years old. Testicular cancer has one of the highest cure rates of all cancers: in excess of 90% if caught in time. Any pain and tenderness in the Testicles, a build-up of fluid in the scrotum, a dull ache in the lower abdomen (or groin), an increase (or decrease) in the size of one of the Testis or blood in semen should be followed up with a GP visit.
Cradle the whole of the scrotum and Testicles in the palm of the hand and feel the difference between the Testicles. One is almost always larger and lying lower. This is completely normal. Examine the scrotum looking for any lumps on the skin or swellings inside. Check each Testicle in turn comparing them with the other for differences. Use both hands and gently roll each Testicle between thumb and forefinger. Check for any lumps or swellings as both Testicles should be smooth and without lumps or swellings.
"The duct that carries sperm to the penis runs along the top and back of the Testicles (the epididymis). This may feel lumpy but it is normal."
