I am disgusted by this disgusting news and even more disgusted at how ignorant disgusted and the rest of you guys are, talking about hereditary and shot in colon and all that bullshit, cancer is caused by your diet plain and simple if your body is highly acidic then that is the environment where cancer cells and tumor grows, keep your body in a alkaline state and cancer cells wont be able to grow, but people are always focus on cures and nobody thinks about the prevention of diseases.
