- most common cancer for men between 15 and 35; all young men over 15 should practice monthly self exams; check for swelling, tenderness, or lumps
A simple 3-minute self-examination once a month can detect one of the cancers most common among men aged 15 to 34. If detected early, testicular cancer is one of the most easily cured.
The best time to check yourself is in the shower or after a warm bath. Fingers glide over soapy skin making it easier to concentrate on the texture underneath. The heat causes the skin to relax making the exam easier.
1. Start by examining your testicles. Slowly roll the testicle between the thumb and fingers, applying slight pressure. Try to find hard, painless lumps.
2. Now examine your epididymis. This comma-shaped cord is behind each testicle. It may be tender to the touch. It's also the location of the most noncancerous problems.
3. Continue by examining the vas (sperm-carrying tube that runs up from your epididymis). The vas normally feels like a firm, movable smooth tube.
Now repeat the exam on the other side.
In the early stages testicular cancer may be symptomless.
When symptoms do occur they include:
lump on the testicle;
slight enlargement of one of the testicles;
heavy sensation in the testicles or groin;
dull ache in the lower abdomen or groin.
If you find any hard lumps or nodules, see your doctor promptly. Only your doctor can make a diagnosis.
This self-exam is not a substitute for periodic examinations by a qualified physician.
