In a TV interview with David Letterman, Oscar-winner Michael Douglas revealed that his throat cancer has spread beyond its original tumour and that his illness is more advanced than was first feared. He also said his throat had been bothering him for several months before the cancer was diagnosed following his summer vacation. “It’s a stage four [cancer], which is intense,” Douglas said. “You want to be at stage one.” Stage four refers to cancers that have metastasised and can be fatal. The 65-year-old actor also said that his illness was probably caused by a lifetime of drinking and smoking. He is currently undergoing chemotherapy and said his odds of survival are around 80 per cent.
