A co-author of this study actually mentions this in the article. It is definitely being looked into.
>"This is important because the p53-encoding gene is the most commonly inactivated tumor suppressor gene in colorectal cancer. In most other kinds of cancer, moreover, p53 is inactivated by mutations or viruses in the majority of cases."
Li-Fraumeni Syndrome is a genetic mutation of p53 that makes you more susceptible to various types of cancers. It's rare, in terms of number of people confirmed to have it, but is likely far more prevalent because it's not generally screened for. Interestingly, I'm told the reasons elephants don't (or rarely) get cancer is because they have 10 copies of p53, whereas humans only have 1.
