“Entertainment Tonight” and “Home & Family” co-host Cameron Mathison revealed he’s currently battling health problems and was recently diagnosed with renal cell carcinoma (also called kidney cancer). He also shared that surgery is scheduled for Thursday to remove a tumor on his right kidney.

He first made the announcement on Monday’s episode of his Hallmark Channel talk show and then followed it up with a post on Instagram.

“I have a health situation that I want to share with you all,” Mathison began his Instagram caption. “There are many reasons I love social media, staying connected with you all, sharing fun experiences... well this time I’m asking for your help.

“About a month ago, I had an MRI for some gut issues I’ve been having, and during that MRI they found a tumor on my right kidney. It’s consistent with Renal Cell Carcinoma... or kidney cancer. The good news is that it hasn’t spread to any other organs. They say my healthy lifestyle and diet has no doubt helped keep it from growing and spreading to other areas, as doctors think it’s been growing in me for minimum 10 years.

“I am extremely lucky that we found it early. Thank you to my longtime friend and urologist @jon_giddens who has helped me tremendously through this process. [Wife] Vanessa, [kids] Lucas and Leila have been absolutely amazing with their love and support... as have my mom, dad, brother, and everyone at ‘Home and Family,’ Hallmark, and ‘ET.’”

Though the “All My Children” alum is “feeling very grateful and optimistic,” with his surgery scheduled for Thursday at 4 p.m. EDT, he’s “hoping to receive positive thoughts, prayers or whatever” people feel comfortable giving. And it didn’t take long after revealing his cancer diagnosis for Mathison to receive just that on social media from many of his fellow Hallmark stars.
