Indie pop star Benjamin Curtis has been diagnosed with lymphoma.
The School of Seven Bells star was admitted to hospital in Brooklyn, New York after weeks of ill health and doctors carried out a series of test to discover what was wrong with the guitarist.
Medics subsequently diagnosed T-cell lymphoblastic lymphoma and Curtis is facing chemotherapy treatment.
His bandmate Alley Deheza has launched an online fundraiser to help pay Curtis' medical bills, and she has detailed his health battle for fans in the Internet appeal.
Deheza explains, "It feels so surreal to be writing this to you... A few nights ago Benjamin was admitted to the hospital for symptoms that have been getting worse for a few weeks now. After a dozen tests and scans (which he's endured like a champion), the doctors say it's T-cell Lymphoblastic Lymphoma.
"It developed pretty aggressively, and the chemotherapy to treat it will be pretty aggressive, but the good news is that it's Treatable. These next few months will be tough, but he is the toughest person I know...
"I wanted to share this with you all, because you guys are such a huge and important part of our lives. Send all of the light and love that you can his way. Every bit will count towards a strong and fast recovery. I believe that with all of my heart. I will be doing the same."
