Wjitch form of cancer is not likely to develop in a person who uses smokeless tobacco

Anything except lung cancer if that makes sense, I don't know what your options are

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.

1. Plant hands directly under shoulders (slightly wider than shoulder width) like you’re about to do a push-up.

2. Ground toes into the floor and squeeze glutes to stabilize your body. Your legs should be working, too — be careful not to lock or hyperextend your knees.

3. Neutralize your neck and spine by looking at a spot on the floor about a foot beyond your hands. Your head should be in line with your back.

4. Hold the position for 20 seconds. As you get more comfortable with the move, hold your plank for as long as possible without compromising your form or breath.
