'Spartacus' star Whitfield dies of lymphoma at 39

LOS ANGELES (AP) — Andy Whitfield, who played the title role in the hit cable series "Spartacus: Blood and Sand," has died at age 39, according to representatives and family.
Whitfield died Sunday in Sydney, Australia, 18 months after he was diagnosed with non-Hodgkin lymphoma, manager Sam Maydew told the Associated Press.
"On a beautiful sunny Sydney spring morning, surrounded by his family, in the arms of his loving wife, our beautiful young warrior Andy Whitfield lost his 18 month battle with lymphoma cancer," Whitfield's wife Vashti said in a statement. "He passed peacefully surrounded by love. Thank you to all his fans whose love and support have help carry him to this point. He will be remembered as the inspiring, courageous and gentle man, father and husband he was."
Andy Whitfield — who was born in Wales and moved to Australia in 1999 — was a virtual unknown when he was cast as the legendary Thracian slave in "Spartacus," a role made famous by Kirk Douglas in the 1960 Stanley Kubrick film.

The series proved a breakout hit for the Starz network and made waves with its graphic violence and sexuality.

While waiting for Whitfield's treatment and expected recovery, the network produced a six-part prequel, "Spartacus: Gods of the Arena," that aired earlier this year with only a brief voiceover from the actor.But in January after Whitfield's condition grew worse, the network announced that another Australian actor, Liam McIntyre, would take over the role.

Whitfield appeared in all 13 episodes of the first season that aired in 2010, and was preparing to shoot the second when he was diagnosed with cancer.

"We are deeply saddened by the loss of our dear friend and colleague, Andy Whitfield," Starz President and CEO Chris Albrecht said in a statement Sunday night. "We were fortunate to have worked with Andy in 'Spartacus' and came to know that the man who played a champion on-screen was also a champion in his own life."
Whitfield's previous credits included appearances on the Australian TV shows "Packed to the Rafters" and "McLeod's Daughters."

What is non-Hodgkin's lymphoma?

Non-Hodgkin's lymphoma is a type of cancer that originates in the lymphatic system. It is estimated to be the sixth most common cancer in the United States. The lymphatic system is part of the body's immune system and helps fight infections and other diseases. In addition, the lymphatic system filters out bacteria, viruses, and other unwanted substances.

The lymphatic system consists of the following:
Lymph vessels: These vessels branch out throughout the body similar to blood vessels.
Lymph: The lymph vessels carry a clear fluid called lymph. Lymph contains white blood cells, especially lymphocytes such as B cells and T cells.

• Lymph nodes: Lymph vessels are interconnected to small masses of lymph tissue called lymph nodes. Lymph nodes are found throughout the body. Collections of lymph nodes are found in the neck, underarms, chest, abdomen, and groin. Lymph nodes store white blood cells. When you are ill and the lymph nodes are active, they will swell and be easily palpable (your doctor can feel them when she examines you).
• Additional parts of the lymphatic system: The tonsils, thymus, and spleen are additional components of the lymphatic system. Lymphatic tissue is also found in other parts of the body, including the stomach, skin, and small intestine.

Because lymphatic tissue is found in many parts of the body, non-Hodgkin's lymphoma can start almost anywhere.
