YouTuber Hank Green diagnosed with Hodgkin lymphoma

YouTuber, science educator, and writer Hank Green announced on Friday that he has been diagnosed with Hodgkin lymphoma, a form of blood cancer that affects the lymph system.

Green, 43, announced his diagnosis in a YouTube video Friday morning. He said he had been diagnosed with the disease after noticing enlarged lymph nodes.

He explained the cancer is considered very treatable and that "the goal is cure."

He said he would begin chemotherapy soon. "I'm not really looking forward to it, but I'm looking forward to starting on the path," he said in the video.

Green has multiple risk factors for lymphoma, including medications, an autoimmune condition and having had mononucleosis in childhood, he said.

Green, who came to prominence through a collaborative YouTube channel with his brother John Green called "Vlogbrothers," said he wasn't yet sure how his diagnosis would affect his work.

"What am I gonna make? I don't know," he said. "I know that I'm gonna feel like garbage," he went on, referring to the effect of chemotherapy treatments. "It's gonna be really unpleasant."
