on my left testicle thereis smallish hard lump. Its not actually attached as such, but if you grip it, it feels like its attached to a very very thin line that attaches to my testiclethis lump has been there for aout 5 years now, im too afraid to go to the doctor, but if its een here so long, it cant be dangerous can it? also it doesnt cause me any discomfort unless i squash it really hard or pull it out too far.
