15. The Night Shift
The International Agency on Cancer classified nighttime work as a probable carcinogen in 2007. Scientists also believe that working during the night and work for extended hours in the darkness can throw the body’s natural sleep and wake cycles out of whack.
Arsenic is toxic in its inorganic form and is often found in contaminated drinking water in places such as Bangladesh, or in areas where irrigation systems water crops with arsenic water. The World Health Organization says at least 140 million people in 50 countries drink water containing high levels of arsenic. It is also one of the cancer-causing agents found in tobacco.
13. Charred Meat And Open Flame Grilling
Although smoky steaks and grilled meats may be tender and tasty, they also increase your risk of cancer due to the muscle meats containing compounds known as heterocyclic amines, or HCAs, and polycyclic aromatic hydrocarbons, or PAHs. According to the National Cancer Institute, when meats like beef, poultry, or fish are cooked over an open flame or pan-fried at high temperatures, the fat, and juices that are released into the fire spark flames with the dangerous chemicals inside that are then cooked into the meat. However, it is not 100 percent proven that these chemicals are cancer-causing, but according to lab tests, they have been found to change DNA in various ways that might increase cancer risk.Related: Top 20 Unhealthiest Foods on the Planet
