The 53-year-old music mogul - the man who discovered Liam and Noel Gallagher's band - has had several growths removed from various parts of his body and in order to stay healthy he is living a completely teetotal life.
Speaking in the 20th anniversary relaunch issue of Loaded magazine - which is out now - former Creation Records boss McGee said: ''I've had polyps removed from my arse, I've had a lump taken from my arm, I've had an exploded ulcer that had to get dealt with and I had Sarcoidosis when I was very young - 26.
''If I was going to write my epitaph it would be, 'He came, he lived, he partied, he departed.' I'm living every day like it's my last. That's like something Charlie Sheen would say. But you've got to enjoy your f***ing life. I have made mistakes in my life, but you can't regret or revisit mistakes. Life is too short.''
McGee - who was 23 when he founded Creation in 1983 with a £1,000 bank loan - had a colon cancer scare in 2003 which he was eventually given the all-clear from but has had to have follow up treatment.
He said: ''Back in 2003 my wife told me that because my mum died of bowel cancer I should go for a colonoscopy.
''I had no warning signs apart from family history. They zapped it with laser treatment and they had to cut out a polyp. If you are over 40, you are supposed to go every five years because if you don't cut them out they turn to cancer.
''Because it was so unpleasant it took me more than five years to go back. By this time we solved it. I got one taken out recently and I am clear.''
McGee - who has a new label, 359 Music - now lives a peaceful life in Wales with his wife Kate, 42, and 13-year-old daughter Charlie and insists he loves being a ''house dad'' and doesn't miss the rock 'n' roll life.
The actress spoke about raising her 11 year old daughter Matilda in the wake of Heath Ledger's death eight years ago.
