Dublin native and Australian Rules football legend Jim Stynes has revealed that three tumors have been discovered in his brain.

Stynes stepped down as as Chairman of Melbourne Football Club after he was diagnosed with cancer in July when he revealed that a lump on his back was cancerous.

The 43-year-old updated the public of his latest news via Twitter. The first entry described the discovery of one of the tumor

"Small bump on recovery, little tumour on brain, will know soon,"  he tweeted "Good news PETscan all clean on rest body. Great support everyone xox."

 A subsequent entry after that reveal that there was more than one.

"Pushed it too far on cycle. In hospital," Stynes wrote. "Feeling better. 3 tumours in brain. Fight cont. Treatm. looks pos+. Specialist 2morrow. Big24hrs! Thx2all."

Stynes was born in Dublin on April 23, 1966 and played Gaelic football for Ballyboden St. Enda’s until he decided to leave Ireland to go down under and take up Aussie Rules football with Melbourne.

Stynes was a natural, and won the Brownlow Medal – the game’s highest individual honor – in 1991 and enjoyed a hugely successful playing career from 1978-98, playing 244 consecutive games in the AFL.

After his playing career wound down he assumed the role of anti-racism officer for the Australian Football League and also played a vital part in the International Rules series between Ireland and Australia, so much so that “The Jim Stynes Medal” is awarded to the best Aussie player every series.

Stynes took over as Chairman of Melbourne Football Club last year, vowing to increase membership and opposing the possible move of the club outside Melbourne.

Not only has he made his mark in football, but Stynes has changed the lives of many children for the better through the Reach Foundation, a nonprofit which he co-founded to inspire young people.

For his charity work he was named Victorian of the Year in 2003 and was awarded an OAM (Order of Australia medal) in 2007.
