Former Chimaira singer Mark Hunter revealed on Thursday (Aug. 1) that he's been diagnosed with thyroid cancer and is receiving treatment. "There's no easy way to say it. I have thyroid cancer. Last year during a physical, my doctor discovered a large mass in my neck," he wrote alongside photos of himself in the hospital and with a bandage on his throat following surgery.

"I had two fine needle biopsies, but the results were inconclusive," he added. "A week ago, I had half of my thyroid removed so doctors could better test the tumor. The results were positive for Papillary cancer- the most common of thyroid cancers. Luckily, it also has a high cure rate. There is no known cause for this type of cancer, but it's likely genetic. There weren't any symptoms either." 

Hunter, 42, said the next step is to remove the rest of his thyroid on Aug. 12th and "explore radioactive iodine treatment." He thanked his team of doctors at the Cleveland Clinic, as well as his friends and family for helping him out of the "depressive dark hole" the diagnosis sent him down. "My mother is also an inspiration for having beat colon cancer, as are many of my friends and fans who've endured much worse," he wrote, encouraging everyone to make sure they get routine physicals. A spokesperson for the group could not be reached for additional comment at press time.

Chimaira broke up in 2014 and briefly reunited in 2017.
