Question

discuss the two main causes of skin cancer.

Explanation:

Skin cancer is a complex disease, but two main causes stand out. Firstly, ultraviolet (UV) radiation from the sun or artificial sources like tanning beds is a major culprit. UV rays can damage the DNA in skin cells, leading to mutations that may result in cancerous growth. Secondly, genetic factors play a role. Some people inherit gene mutations (e.g., in the CDKN2A gene) that increase their susceptibility to skin cancer. These genetic predispositions can affect how skin cells repair DNA damage or control cell growth.

Answer:

The two main causes of skin cancer are ultraviolet (UV) radiation exposure (from the sun or artificial sources) which damages skin cell DNA, and genetic factors (inherited gene mutations) that increase susceptibility to cancerous cell growth.
