Hello I'm 18 have had a small lump not rock hard not soft. Outside of the left testicle had it since Wednesday that day had a blue/purplish ball that colour has now gone and it feels the lump is smaller only by a tiny tiny bit. I have had no pain at all. and it doesn't feel its even there. Only when I try to feel it. I can move it about but it goes back to its place. So had it for 5 days now what could it be?
With that said, while I'm no expert here, anything that seems out of the ordinary when it comes to lumps in the testicles should probably be examined by a medical professional, since masses or lumps are one possible sign of testicular cancer.
You say there isn't any pain, and I'm assuming that there isn't any noticable swelling, so you're probably in the clear. The fact that you're 18 also means its probably NOT testicular cancer. Nonetheless, you might want to ask your doctor about it.
I am 43 yrs old male, last year I had an Inguinal hernia operation on the left side. Months later there was pain in that region which upon diagnosis led to the left testical where a small grain size lump was noticed. I was refered to the Urologist who refered me for ultrasound and for the blood test. Blood test results were clear but ultrasound result shows a substance in my left testical so I was refered again for another ultrasound after few months to see if the lump was growing. On the second examination the lump is the same size, and I have been given another date for ultrasound in 4 months time to montior the lump. I will keep you posted of any conclusive result, but so far it looks like a trauma due to internal injury and nothing more. Fingures crossed
