Mark Ruffalo: Health, Hulk Role, and Three Oscar Nominations

Mark Ruffalo found his defining role as the Hulk, but only after a brain tumor nearly ended his career. Diagnosed with an acoustic neuroma in 2001, he rebuilt his voice and his life — and went on to earn three Oscar nominations and become a leading voice for climate justice.

Born: November 22, 1967 (Kenosha, Wisconsin) · Oscar nominations: 3 (Best Supporting Actor) · Known for: Bruce Banner / Hulk (MCU) · Spouse: Sunrise Coigney (married 2000) · Health diagnosis: Acoustic neuroma (vestibular schwannoma)

The key facts about Mark Ruffalo span his biography, health journey, career, and personal life — one pattern: resilience through adversity.

What was Mark Ruffalo diagnosed with?

In 2001, shortly after completing work on The Last Castle, Ruffalo was diagnosed with a vestibular schwannoma — commonly called an acoustic neuroma (Wikipedia biography). The tumor is benign but grows on the nerve that controls hearing and balance.

Acoustic neuroma diagnosis and surgery

Ruffalo underwent surgery to remove the tumor. The operation was successful, but the aftermath was severe. “My face was totally paralyzed on the left side for about a year,” he later told People magazine (celebrity health reporting).

• The tumor was benign and non-cancerous (OncoDaily (medical news site))
• Surgery left him completely deaf in one ear (People magazine)
• Recovery took about one year

Partial facial paralysis recovery

The facial paralysis was temporary but deeply disorienting. Ruffalo documented the experience in a video titled Acoustic Neuroma – Mark Ruffalo’s Story (YouTube (patient advocacy channel)). He has said that learning to speak and emote again was like “starting over”.

Long-term hearing loss effects

Ruffalo has permanent hearing loss in his left ear. He has adapted by relying on his right ear on set and in everyday life. A blog about bone-anchored hearing aids (hearing loss resource) notes that Ruffalo’s case is a well-known example of how acoustic neuroma survivors manage unilateral deafness.

Mark Ruffalo’s recovery from acoustic neuroma redefined his approach to acting and deepened his resolve, setting the stage for his later career and activism.
