Aspirin sales must be hurting

"Although the Lancet-published studies received no specific funding, Rothwell has received honoraria for serving on advisory boards, clinical trial committees and giving talks from some pharmaceutical companies with an interest in anti-platelet agents, including Bayer, AstraZeneca, Boehringer Ingelheim, Sanofi-BMS and Servier."

That pretty much says it all.  If not, Google "aspirin dangers".  And then check and see how many of the aspirins used in studies which showed benefits for reduced risk of stroke and/or heart attack were buffered with magnesium.  All of the early studies which showed benefit used aspirin with magnesium and I suspect we may see some of the same effects for the anti-cancer aspirin products.

At any rate, changing to a healthy diet and lifestyle and building and keeping a strong immune system is the ticket for preventing cancer, not taking drugs.  No one gets cancer or becomes ill due to a deficiency in aspirin or any other pharmaceutical item.  A great many do become ill from taking unnatural pharmaceutical products.
