There is no conclusive evidence that passive smoking (also known as second-hand smoking) is associated with risk of endometrial cancer. Only a small number of low-quality studies have been conducted.

Passive smoking means breathing in the smoke from other people’s cigarettes, cigars and pipes. This smoke is made up of the smoke that the smoker breathes out and the smoke that comes from the burning cigarette.

Second-hand tobacco smoke contains the same cancer-causing chemicals that are inhaled by smokers and is known to cause cancer of the lung.
