TOWSON, Md. —The cast of CBS’s hit comedy show “The Big Bang Theory” has filmed a public service announcement to raise awareness about skin cancer after learning of the death of a young Maryland fan.

The Baltimore Sun reported that the video features the cast reminding young fans to have their skin checked by a dermatologist for melanoma.

The cast filmed the spot after learning about 17-year-old Claire M. Wagonhurst, a Baltimore County high school student who died from adolescent melanoma in October 2014.

Her mother, Marianne Banister, said her daughter frequently watched “The Big Bang Theory” as the melanoma progressed.
