Final answer:
Skin damage from sun exposure is indeed cumulative and doesn't completely heal, which can increase the risk of skin cancer and accelerate skin aging, leading to wrinkles. The most deadly form of skin cancer is melanoma.
Step-by-step explanation:
The statement you're referring to is indeed true: skin damage resulting from exposure to the Sun is cumulative. This means that the skin doesn't completely heal from previous sunburns, and over time, this can lead to an increased risk of skin cancer. When skin is exposed to UV light, particularly UV-B and UV-C rays, it can lead to sunburn.
Repeated and large exposures to UV light not only increase the risk of cancer but can also accelerate the aging process of the skin, leading to wrinkles. Moreover, getting sunburned, especially during childhood or teenage years, can significantly increase the risk of developing skin cancer later in life. Lastly, the most deadly form of skin cancer is melanoma, which affects the melanocytes capable of spreading to other organs.
