Most testicular lumps are harmless (like cysts), but a painless lump can be the first sign of testicular cancer — which is highly curable when caught early. So any new lump should be checked promptly.
Check monthly, ideally after a warm shower when the skin is relaxed
Roll each testicle gently between fingers and thumb, feeling for lumps
Know what is normal for you (the epididymis at the back is a normal soft tube)
Look for a hard, painless lump, swelling, or a change in size/weight
Any new lump or change → see a doctor
When to see a doctor urgently
A hard, painless lump or swelling in a testicle
A feeling of heaviness or a dull ache in the scrotum or lower belly
Sudden severe testicular pain (possible torsion — emergency, see next)
Any change in size, shape or firmness
Most are harmless — but always check. Testicular cancer is very treatable when found early, and a painless lump is the classic sign, so never ignore one. MedDroid gives general information, not a diagnosis.
