It depends what type of caner: Lung: avoid smoking or toxic fumes Skin: Ultraviolent radiation etc.
Ozone layer protects us from the harmful UV radiations of the sun. It filters out these harmful radiations. It is present in stratosphere.

Ozone (O3) in the stratosphere absorbs ultraviolet (UV) radiation, particularly UV-B and UV-C. This absorption plays a crucial role in protecting Earth's surface from harmful UV radiation. Additionally, certain greenhouse gases like methane and nitrous oxide can also absorb some UV radiation in the upper atmosphere.
