Gene mutations leading to cancer could be a result of your lifestyle more than your genetic makeup. A new cancer study has tried to disprove the “bad luck” cancer theory—that you get cancer as a result of bad luck or inevitable family history and there are no concrete ways to identify other potential causes. But this study aimed to prove other causes, explaining that cancer is “…caused either by intrinsic factors that are part of the innate way the body operates, such as the risk of mutations occurring every time a cell divides, or extrinsic factors such as smoking, UV radiation and many others that have not been identified…the results consistently suggested 70-90% of the risk was due to extrinsic factors.” While a healthy diet and healthy lifestyle overall does not guarantee that you will never be diagnosed with cancer, it does significantly improve your chances.
