Skin cancer rates have more than tripled since 1975, due in part to the depletion of the ozone layer and the ever-rising popularity of tanning. But this isn’t the only reason for increased cancer rates in recent years.

Scientists recently discovered that those who undergo organ transplants are more susceptible to skin cancer because they take immunosuppressant drugs during treatment. These drugs stop the body from rejecting the donated organ, but it also leaves the body vulnerable to preventable diseases, especially skin cancer.

While it’s believed that people of color, especially black people, do not contract skin cancer due to the amount of melanin in their skin, the a study has found evidence dismissing this claim, especially regarding those who have received organ transplants.

A new study conducted by the Drexel University College of Medicine recommends that all organ recipients should receive skin cancer screenings, regardless of race.
