Almost half the deaths (48.5%) from 12 different types of cancer combined are attributable to cigarette smoking, according to a study by researchers from the American Cancer Society and colleagues. Cancer types known to be caused by smoking include cancer of the liver, colon and rectum, lung, oral cavity and throat, esophagus, larynx (voice box), stomach, pancreas, bladder, kidney, and cervix, and acute myeloid leukemia.
I would presume skin cancer doesn't apply, breast cancer, prostate cancer, testicular cancer, and vaginal cancer are all the least likely ones.
