Charles Kelley has filmed a public service announcement about colon cancer as a special thanks to the medics who are helping his father-in-law battle the disease.

It's really been hard on the family, so it hit really close to home. Any time my band can use our platform to encourage more people to get screened, that is a positive thing

The Lady Antebellum star taped the ad in Nashville, Tennessee on Monday and he hopes it encourages fans to sign up for health checks.

Kelley's father-in-law was diagnosed with colon cancer a few years ago and he says, "It's really been hard on the family, so it hit really close to home. Any time my band can use our platform to encourage more people to get screened, that is a positive thing".

Kelley's PSA also features his wife and her parents and it will run as part of Colorectal Cancer Awareness Month in March, according to USA Today.
