"Another idea was that cancer arises from the chronic irritation of tissues. This view received strong support with the discovery of X-rays in 1895 an"d the observation that exposure to this form of radiation could induce localized tissue damage, which could lead in turn to the development of cancer.

So what significance will this have for PE? Because it seems that growth is the direct result of chronic damage to the penis. I did not post this thread to scare anyone since no one really knows the true cause of cancer, however it is something to keep in mind as we also do not know the long term consequences of pulling our units day in and day out ;)
DISCLOSURE: PEer since 2003
The "damage" she’s referring to in the cases of lung cancer from smoking and cancer from exposure to x-rays can be explained by the damage that ionizing radiation causes to DNA and the consequent defects in cell metabolism and division that result.
Everyone knows that x-rays are a form of ionizing radiation, but few know that cigarettes are, too:
Besides carbon dioxide, tar, and nicotine, cigarette smoke also contains radioactive lead and polonium, enough to result in a radiation exposure of 1300 mrem/year to a 1.5 pack a day smoker. Each cigarette smoked can also be equated to one chest x-ray, and a non-smoker living with a smoker may receive the equivalent of 12 chest x-rays per year as a result of second-hand smoke. Perhaps the easiest radiation exposure to control is this one: If you smoke, stop; if you don’t smoke, don’t ever start. Whenever possible, minimize your exposure to other people’s smoke. For more information about smoking, see the Quitting Smoking Fact Sheet. http://www.uihe althcare.com/to … nradiation.html
Radiation doesn’t explain liver cancer, but I’ve managed to pare down the number of examples from 3 to 1.
By the reasoning you’ve proposed, exercise would be carcinogenic, since it causes persistent damage to the muscles and joints. Do bodybuilders get muscle cancer? I don’t think so.
The main concern I had about PE causing cancer was that it might result in excessive cell division. In general, the more often cells divide, the greater the likelihood that something will get screwed up and and some cancerous process will develop.
