I'm not sure about how prevention interferes with inherited traits, but it is known that cancer is highly preventable. Just type in "cancer prevention" on a search engine.
From memory, these kind of things prevent cancer:
1) Not smoking
2) Eating a healthy diet, that is high in fruits and vegetables
3) Not drinking alcoholic beverages in excess
4) Exercise
It is thought that about 50 to 80 percent of all cancers (in general) could be prevented this way. In some countries, where these healthy conditions exist, some forms of cancers are very rare. I don't believe that they really know completely why cancer is preventable, but there's clear evidence that you can reduce your chances of getting cancer.
In my opinion, I feel that the medical community doesn't mention this enough. Over 200,000 deaths each year could be eliminated just in the United States alone, with preventative measures.
Maybe someone can add their thoughts to this.... It's been a while since I read up on it.
