Selangor captain Brendan Gan has been diagnosed with testicular cancer, his club announced on Monday.

According to an official statement from the Malaysian Super League side, the Malaysia international already underwent a surgery to remove the tumor and is now being closely monitored by their medical team.

"Despite being diagnosed with the condition, he remains optimistic and in fact, stronger than ever.

"We hope everyone will pray for his health and provide him some privacy during his recovery. Our captain is determined to recover and eager to come back and be with the team as soon as possible.

"We would like to wish him a speedy recovery and will always pray for his good health," read the statement.

The Australian-born midfielder, who also played for the likes of Perak, Kelantan and Perth Glory, also took to social media to address his latest health condition.

"Cancer won't define me, it's only a short scenic route that I will navigate through and get back to my blessed path that I was living prior to this.

"My motivation is to fight the big ‘C’ and get back out there leading the boys very soon," he posted on his official Instagram account.
