HHS identifies known and likely carcinogens

The NTP did not identify any clinical studies that evaluated the relationship between human cancer and exposure to 1-bromopropane. However, inhalation exposure to 1-bromopropane in rodents caused tumors in several organs, including the skin, lungs, and large intestine.

Cumene

Cumene is a flammable and volatile liquid with a gasoline-like odor. It is a natural component of coal tar and petroleum, and is found in tobacco smoke. It is used primarily to make acetone and phenol.

People are mainly exposed to cumene through the environment and in workplaces that use or produce cumene. It can be found in emissions from petroleum products.

Inhalation exposure to cumene caused lung tumors in male and female mice, and liver tumors in female mice. The NTP did not identify any clinical studies evaluating the relationship between cancer and exposure to cumene.
