The Hot Rod's New Battle!

WWE Hall of Famer “Rowdy” Roddy Piper has been diagnosed with Hodgkin’s lymphoma. Also known as Hodgkin’s disease, Hodgkin’s lymphoma is a form of cancer found in the body’s lymphatic tissue. The lymphatic system helps filter out bacteria and is important in fighting diseases. Piper was sent home early from WWE’s early-November tour of the United Kingdom and hospitalized for surgery, where doctors removed a mass at the spinal cord with an enlarged lymph node. The mass was completely removed, but the lymph node was positive for Hodgkin’s lymphoma.

Radiation therapy is used to treat Hodgkin’s lymphoma; it is an extremely successful procedure, so the prognosis is very good for Piper.

According to Roddy Piper's website, the Hot Rod felt he has been fighting his whole life. My deepest sympathies go out to Piper and his family!
