I am a professional diver and I have to get medical check ups every other year in order to pass and get my work permit. I live a very healthy lifestyle when I am at work, but in my free time I do like to drink at times, do nothing major. You can imagine that I felt shocked when they told me after my check up that I have a lump on my kidney. Anyone else with this problem and can you tell me more about this? I am going to have more tests, and for now, this is all I know... Any comments would definitely be gratefully received.
