Without considering the veracity of this article or the underlying methodology employed, what if it were true that cancer is a random event?

Setting aside that it is only a co-factor and there are other dimensions such as the type and virulence, what does this inform us about research funding? Is this a veritable cash cow for researchers and ripe with charlatans?

After examining 32 different kinds, researchers determined that 66% of all cancers were driven by chance, 29% were due to environmental causes, and 5% inheriting a mutation.

Op. cit.

Sure, different cancers have different correlative percentages, whether 35% for lung cancer or 95% for prostate cancer, and there may be different covariant factors, but, as might be the case for prostate cancer, we only have about 5% to address systematically, and we don’t even know that tweaking within this 5% will have ant material benefits to the health outcome of the patient. At least we have 65% of leeway for lung cancer.

Is there an inverse relationship between the proportion of randomness and positive health outcomes?

I don’t know the answer to these questions. I am also aware that some randomness is probably due to methodology, approach, and simply not necessarily fully understanding the mechanisms behind cancer—or the cause of the seemingly random genetic mutation. I’m not sure how one selects a control group to limit other causes.
