MELBOURNE president Jim Stynes admits he still has a mix of good days and bad as he continues his battle with cancer.

Stynes, who discovered tumours in his back almost two years ago, was on hand for the announcement that singer Olivia Newton-John will perform three songs at the Melbourne v Carlton game on May 27.

The performance is part of a campaign to raise $10 million for the Olivia Newton-John Cancer and Wellness Centre, due to open next year.

"I'm feeling pretty good," Stynes said when asked about his health.

"To me it's a journey. It's up and down and I play it as it goes. Cancer is one of those things. It is very unpredictable and I've been very fortunate. I've survived as long as I have and I hope I continue to do so.

"The people and supporters have been really great. For anyone battling cancer, part of the big journey is staying positive and keeping a really good frame of mind."

Stynes paid tribute to his friends and family as well as the thousands of strangers who had offered their best wishes in his public fight.

"I've had terrific support and I think the real key is being able to stay positive. I've got wonderful people around me who have helped as well as great physicians and great supporters," he said.

"Everyone's been behind what I've been trying to do. I hope we get the same sort of result when we get there on the 27th of May and get a good crowd here. It's been really important."

Stynes stood alongside Ms Newton-John, who had her own public health scare when she was diagnosed with breast cancer in 1992.

The star of Grease and Xanadu joined the chorus of support for Stynes and said she was amazed at how he had taken on his illness.

"I don't think he needs any advice from me. He's inspiring me. I've been so moved and privileged to spend a couple of days with him talking about his journeys," Ms Newton-John said.

"We just met and we had to talk about our cancer experiences one on one. It's a pretty private experience and we've been able to share that."
