Cigarettes
Despite the tobacco industry trying to cover it up, we've known for years that tobacco smoke contains at least 70 cancer-causing chemicals. This also affects people who are around someone while they are smoking.
The Centers for Disease Control and Prevention states that "non-smokers who are exposed to smoke at home or at work increase their risk of developing lung cancer by 20-30%."

According to the US National Cancer Institute, when meats such as poultry or fish are cooked over a hot flame or in a skillet at high temperatures, the fat and juices react with dangerous chemicals that remain in the meat and which we eat later.
The World Health Organization says that processed meats like hot dogs, ham, bacon, and sausage can cause cancer.
Alcohol
Regular and excessive alcohol consumption can increase the risk of developing several types of cancer, including throat, liver, breast, and colon cancer.
