Toward personalized skin cancer care: multiple skin cancer development in five cohorts.

Question: How many skin cancer patients are treated for more than one skin cancer and how soon after the first skin cancer do they occur?Findings: 43% of patients were treated for more than one skin cancer, the majority of which occurred within two years after the initial skin cancer. Just 3% of patients were treated for 10 or more skin cancers, but these patients accounted for 22% of all of the skin cancer treatments in the cohort Meaning: Nearly half of all skin cancer patients were treated for multiple skin cancers, while those without a second skin cancer after two years were less likely to be treated for a subsequent skin cancer within the next five years.
