The Rolling Stones' Ron Wood revealed that he feared the worst after he was diagnosed with lung cancer three months ago.

The 70-year-old guitarist said he thought it might be “time to say goodbye,” after a doctor performing routine tests told him that he “had this supernova burning away” on his left lung. The musician says he told the doctor to get it out of him.

Wood, a smoker for 50 years, told The Daily Mail on Sunday that he had decided not to have chemotherapy, even if it turned out the cancer was aggressive.

“I wasn’t going to lose my hair. This hair wasn’t going anywhere,” Wood said

He thanked doctors in May for treating a small lesion on his lung and will undergo checks every three months.

Wood quit smoking last year after his twins were born.
