London, Dec 31 (IANS): Singer-musician Brian May is terrified with weeks of medical probes surrounding a cancer scare.

The rock legend, known for his association with band Queen, has more reason to worry because he is now 66, the same age that his dad Harold died from cancer, reports dailystar.co.uk.

"On hearing the C word something happens inside you, of course. I’ve seen so many of my dear friends fighting it and my dad lost his battle at age 66, the age I am now. So over the last few days I’ve been in various states of unrest," he posted on his Brian's Soapbox blog.

The guitarist recently underwent a knee replacement surgery. He said that he first noticed pain in his “backside” in September, and he assumed that his body was adjusting to the operation until the pain increased so much that he could hardly stand up.

“I had to give up on going anywhere if there was standing up involved. My general practitioner sent me for a set of MRI scans. Well, that’s when it all became a health scare,” he added.

Now “strange things” have been discovered on his bones, and he had to get blood tests, ultrasounds and scans done.

When these ruled out “nasty” conditions, May felt “cautiously optimistic”.

“Of course we still don’t know what those things on the MRIs are. I guess I’m still in the scare scenario, but with good hopes.

“My specialist guys have also been really positive, reassuring me that if they did find anything in the C word category, it was almost certainly treatable with success," he added.
