Tanning is better than getting sunburnt..., right?

Both are dangerous, because both result from DNA damage to the skin cells. It is true that sunburn has been directly linked to melanoma – one blistering sunburn more than doubles a person's chances of developing melanoma later in life. It is usually thought that lifetime sun exposure is responsible for increased risk of squamous cell carcinoma, while both intense, intermittent sun exposure – the pattern that is traditionally linked to melanoma – and lifetime exposure are believed to be involved in the development of basal cell carcinoma. However, studies have also shown a marked increase in melanoma incidence in people who have developed either squamous cell carcinoma or basal cell carcinoma. Scientists are still trying to determine the exact exposure pattern behind the development of the different types of skin cancer, but it is safe to say that both burning and tanning play major roles in skin cancer.
