I am very worried that i might have Testicular cancer But i am not sure. I first noticed something a couple of years ago when i first started pubity however thought it would go away. I read up about it and thought it might be somthing else. However i read about what i thought it was and it cant be that. It feels like its full of fulid, when i stand up it becomes very large and spreads to a large area on my left testical. When i sit down there is nothing there and both tescials feel the same. I am pretty sure that its part of the tube leaving the tesical itself. Its not hard and does not hurt its. I can move my fingers through it. I am planning to see my docotor but i am so worried that its cancer and might ruin my future. Thank you for your help.
