New study in the Lancet says that one-third of ca deaths annually are preventable. Here is the list of risk factors:

Those nine risk factors are:

—Smoking

—Being overweight or obese

—Physical inactivity

—Low intake of fruits and vegetables

—Alcohol use

—“Unsafe” sex

—Indoor smoke from household use of solid fuels

—Contaminated injections in health care settings

—Air pollution

Of these, being fat, smoking, inactive, drinking ethanol, and not eating veggies are actually on the list of things I can do to avoid ca. Being male, I don't get cervical cancer (the sexually transmittable one). I think lung ca is a big problem of course, but many people are not smoking and still getting it, which suggests environmental or genetic factors; things you really can't do much about. Anyway I am not sure these stats are right (from the usual blogger 'it doesn't seem right' mentality), i would expect that proper diet and exercise would prevent much more than 1/3 of ca. I think people will hear about this study and go back to sitting on their asses, drinking and smoking and watching football, if 2 of 3 will die due to things beyond their control.
