Expert Solution
Skin Cancer
Skin cancer generally occurs due to damage of the melanin pigments protecting the outer layer of the skin due to exposure of UV radiation from sunlight. Cancer genetics are familial i.e., there is a hereditary connection when it comes to inheriting mutated genes from parents. As such, those with family history of skin cancer should avoid direct contact with sunlight as much as possible.
