The actual study said that almost half (44.4%) of cancer deaths were attributable to any risk factor, not just those. Smoking is by far the biggest risk fctor, coming in at over twice the attributable deaths than alcohol and high BMI combined. Cervical cancer from STIs, high blood glucose, and air pollution were almost as high as alcohol and BMI. Of these, one has a very low effort solution on the personal level: get the HPV vaccine (Gardasil). Have your kids get it too. HPV causes many cancers in both men and women, but by far the most significant in terms of number of attributable cases is cervical cancer. Almost half of people have HPV, but it's never tested for and you won't know you have it until you get cancer. Gardasil may either save your life, save the life of your partner, or save the life of a stranger (by preventing the spread of HPV in general). Quitting smoking, alcohol, or junk food can be hard, but getting Gardasil is easy.
