Several Bossier sheriff's deputies have battled cancer. One of them is Preston Parker, who works in Probation. His wish is that his story might encourage someone else who is battling the disease.

Deputy Parker was in his late 20's in 2007, when he graduated from the police academy. It wasn't long after that he was diagnosed with cancer. In his video, he tells the story of how he went from 190 pounds to 120, was told he might not even live, and for sure that he couldn't have any children.

He and his wife, Emily, went through struggles individually and in their marriage, and fought through it together. Emily gave birth to their son Luke in 2011, and now baby number two is on the way.

Take a look at Parker's journey:

The Bossier Sheriff's Office will have a team called "Deputies Making a Difference" participating in Relay for Life of Bossier Parish. It's going on Friday, April 25th, at 6 p.m. in the parking lot of Harrah's Louisiana Downs.
