Just over two months ago, Robin Gibb said that he was feeling "fantastic" following the successful removal of a growth on his colon. "I feel better than I did 10 years ago," he told BBC Radio 2. "I'm active, my appetite's fantastic, the plumbing is all in perfect working order."


Unfortunately, that optimism appears to have been checked by an advanced form of colorectal cancer Gibb has now revealed he's battling. The 62-year-old fell into a coma last week after developing brain swelling from liver failure, as well as pneumonia. Doctors feared the worst.


"Only three days ago, I warned Robin’s wife, Dwina, son, Robin John and brother, Barry, that I feared the worst," said Gibb's physician and gastroenterologist, Dr. Andrew Thillainayagam, in a statement "We felt it was very likely that Robin would succumb to what seemed to be insurmountable obstacles to any form of meaningful recovery. As a team, we were all concerned that we might be approaching the realms of futility."


Thankfully, Gibb did come out of his coma and is now lucid and speaking.


"It is testament to Robin’s extraordinary courage, iron will and deep reserves of physical strength that he has overcome quite incredible odds to get where he is now," Thillainayagam said.


According to HuffPost UK, Gibb is still "exhausted, extremely weak and malnourished," and is currently in intensive care, being fed through a tube and breathing with assistance from an oxygen mask.


The fourth most common cancer in the world, colorectal cancer was diagnosed in 1.23 million new cases in 2008. According to Wikipedia, symptoms include "worsening constipation, blood in the stool, weight loss, fever, loss of appetite, and nausea or vomiting" in most people over the age of 50. As 60 percent of all cases diagnosed come from the developing world, it's believed that lifestyle choices (smoking, obesity, red meat) play a large role in causing it.


As for Gibb, his doctor says the road ahead is uncertain "but it is a privilege to look after such an extraordinary human being."
