Thus, cancer is the consequence of an accumulation of genome alterations, somatic mutations (mutation affecting all types of cells except germ cells).
The mutation rate can be increased by some agents of the environment. This is the case of ultraviolet (UV) radiation that causes DNA damage and is responsible for many but not all skin cancers.
I’m not sure good luck with that ome
