What are the symptoms of skin cancer after your sunburn peels away and heals up?

Does it persist? Sunburn has been shown to increase the risk of developing skin cancer many years later. Sunburn does not cause immediate cancer. Severe sunburn my require treatment by a physician or specialist. Was there was a skin lesion before the sunburn, or has it changed? Or if your skin does not heal or there is a persistent lesion, have it examined.
Your question? It is very unlikely that a skin cancer will immediately form at the site of a sunburn. Even if a skin cancer does occur after a sunburn, it generally takes years or even decades.
