What is a lump on my testicle?

Question

Accepted Answer

First: get it examined - that is the correct move for ANY new testicular lump, and it is not an overreaction. The reassuring arithmetic: most testicular lumps turn out benign. The common benign causes, per the NHS: epididymal cysts (smooth, separate-feeling lumps on the cord-structure behind the testicle - harmless collections of fluid); hydroceles (fluid around the testicle - a soft, sometimes large, sometimes transilluminating swelling); varicoceles (enlarged veins in the scrotum - the classic "bag of worms" feel, usually left-sided, usually harmless though occasionally relevant to fertility); and epididymitis (infection-driven tenderness, usually painful rather than a silent lump). The reason the exam is non-negotiable: the serious cause - testicular cancer - typically presents as a PAINLESS lump or firmness, so painlessness is not reassurance; and it is one of the most treatable cancers there is when caught early, which men usually do when they get checked promptly. The exam itself is quick: feel, possibly an ultrasound, done. The urgent version: sudden severe testicular pain with a high-riding testicle is torsion - an emergency measured in hours, not days.
