The study is retrospective and not the classical double blind model. The women diagnosed as dying from the cancer had to have a cause of death directly cited as being attributed to the cancer. If you take aspirin and you're healthy the biggest risk is bleeding. This risk goes up several fold for cancer patients, and goes up through the roof for anybody on radiation or chemo due to the internal scarring and the decreased platelet counts.
Aspirin is great as an anti-inflammatory. The problem with say "breast cancer" is that there are many different types. Aspirin, or rather anti-inflammatory medications should be a mainstay treatment in cancer regimens. Ultimately the patient would have to trust their oncologist to make a recommendation as to how to treat their individual cancer.
The article may not appreciate big pharm (and to be honest I'm disgusted with their direct to patient advertising) but the big pharm in the US are pretty much the only ones making the last 9 new chemo agents that did not exist 4 years ago.
Ultimately the cure for cancer will not be chemo mediators but rather cellular attack techniques which go back to molecular biology rather than biochemistry.
As a doctor what do you think of the possibility that ketogenic diets being helpful in treating cancer? I read an interesting article about starving cancers of glucose to stop growth.
I'm not an oncologist so I don't know too much about the growth capabilities of malignancies. Certain organs in the body such as the human brain rely solely of glucose for metabolism (hence why you get lightheaded with low blood sugar). Other organs such as the heart rely on branched chains for metabolism.
Each type of cancer is different since it originates from different tissue. The less differentiated it has become (as seen by doing cell flow cytometry) the worse the cancer is because it had gone back to being more or less a stem cell which can feed off glucose.
So it might be helpful in a poorly differentiated cancer but usually people who have those have Stage III or Stage IV cancer and the battle is probably lost.
