The text claims that sunburn is caused by DNA damage in skin cells to prevent cancer.

Infact verdict: Mostly True (62/100).

The claims about sunburn and DNA damage involve a mix of scientific facts and misinterpretations. The first claim that sunburn is caused by DNA damage resulting in cell death is partially supported by scientific evidence, which states that sunburn causes RNA damage leading to inflammation and cell death. DNA repair mechanisms are also activated to fix any UV-induced DNA damage. The claim is rated true based on scientific support, though emphasis should be on RNA rather than DNA damage. The second claim incorrectly associates the DNA damage from sunburn with direct cancer prevention. Instead, cancer prevention is mainly achieved through the use of sunscreen and protective measures. The claim that DNA damage prevents cancer lacks support, as the opposite is more accurate; DNA damage from UVB rays increases cancer risk if not repaired.
