Well lets look at the causes of cancer. Smoking is one. Skin cancer is another. A lot of cancer is caused by harsh chemicals and radiation. Its caused by what you eat and drink. Smoking- man made killer. Skin cancer- We had what was called an ozone layer, man has destroyed it. Chemicals and radiation. Manmade killers which are put inot food and what not. As far as I know and dont quote me because I dont profees to have all the answers, but if anyone does get cancer, it is our own fault. We decided to modify what God gave us and its killing us. I'n not saying that we deserve to get cancer, it is sad that it spreads and some people do get cancer through no fault of their own. The only way to prevent cancer was to not modify everything and live as nature intended. This problem started a looong time ago.
