Brian May’s health problems may have taken a turn for the worse. Last week we reported that he had undergone an MRI for some back issues. Now, we learn that the procedure uncovered “abnormalities” that have caused his doctors to recommend “urgent attention” in case of cancer.

On Saturday (Dec. 28), the Queen guitarist disclosed the news on his website. He wrote:

The scans showed up all kinds of mechanical disc and vertebra problems that might be the cause of the pain, but there were also some abnormalities in the bones - things that the report said needed urgent attention. So around Christmas I've been having a succession of blood tests, ultrasounds, and various kinds of scans, to see if they could rule out various kinds of cancer.

Now, 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, exactly the age I am now. So over the last few days I've been in various states of unrest. But the great thing has been that the team my GP assembled to check out the possibilities has moved Heaven and Earth to gather all the information I need quickly over the Christmas period … not an easy time.

So far, the tests have ruled out cancer, but May is not out of the woods. In a post he wrote yesterday thanking fans for their support, he disclosed that he was going for another scan later that day, and they still haven’t figured out “what those things on the MRI's are.”
