Detailed explanation-1: -Cigarette smoking causes cancer of the mouth and throat, esophagus, stomach, colon, rectum, liver, pancreas, voicebox (larynx), trachea, bronchus, kidney and renal pelvis, urinary bladder, and cervix, and causes acute myeloid leukemia.
Detailed explanation-2: -Age, weight, exposure to carcinogens, and genetics can increase the risk of developing cancer.
Detailed explanation-3: -Leading risk factors for preventable cancers are smoking, getting too much ultraviolet (UV) radiation from the sun or tanning beds, being overweight or having obesity, and drinking too much alcohol.
Detailed explanation-4: -Tobacco use, infectious agents, unhealthy diet, excess body weight, physical inactivity, and alcohol consumption account for the majority of cancer deaths caused by known risk factors.
Detailed explanation-5: -Chemicals from cigarettes damage DNA. Cigarette chemicals make it harder for cells to repair any DNA damage. They also damage the parts of DNA that protect us from cancer. It’s the build-up of DNA damage in the same cell over time that leads to cancer.
