Brian May has been given the all-clear after suffering a cancer scare in late 2013, the Guardian reports.

Writing on his official website, the 66-year-old Queen guitarist informed fans results from urgent tests carried out in December showed he did not have prostate cancer, although he stated there were “still some mysteries to solve” regarding his health.

Detailing a conversation with a medical specialist he wrote: “He said, ‘I have good news. The result of your prostate biopsy is here, and we did not find any cancer cells.’ I celebrated in the studio with a cup of tea. Hey – I know how to rock!”

May also wrote about working with bandmate Roger Taylor on unfinished Queen recordings, which include cuts from the band’s 1980 sessions with Michael Jackson, as well as with their late frontman Freddie Mercury.

“The track we dusted off today has the four of us, Freddie, John [Deacon], Roger and myself, playing together on a track we’d all forgotten about, that was never finished,” May explained. “It sounds so fresh … and, well, it’s crying out to finally be brought into the world. What’s great is nobody has got a hold of this and leaked it. I can’t help but feel a buzz. I’m energised again. It’s nice to be putting the Queen hat on again for a while. This year will be interesting, to say the least.”
