Eisner Award-winning cartoonist Darwyn Cooke is battling an "aggressive" form of cancer.

The news was announced this morning by Cooke's wife, Marsha, via the artist's official blog.

"It is with tremendous sadness that we announce Darwyn is now receiving palliative care following a bout with aggressive cancer," Marsha writes. "His brother Dennis and I, along with our families appreciate the outpouring of support we have received. We ask for privacy as we go through this very difficult time."

Marsha Cooke further requests that any urgent communications go through Cooke's agent, David Hyde.
