Actor Barton Cowperthwaite posted about being diagnosed with a brain tumor on Instagram.

He posted about his diagnosis on Instagram in detail. The post included a photo of himself and scans of his brain.

“So…. Yesterday I was diagnosed with at least a stage 2 Giloma. It is a fairly decent sized brain tumor. The tumor's cells originate in the brain, so it's not spread from a cancer anywhere else in the body,” the 31-year-old actor wrote.

Luckily, the prognosis seems good.

“The only course of treatment for something like this is brain surgery. Docs so far have been confident that they'll be able to remove most of the tumor, and that after a successful operation, and some rehab, I will be operating like my (amazing, talented, brilliant, hilarious) self. That being said, it seems like scans and check ups will be apart of my life for its lengthy remainder,” he continued.
