  Robin Gibb of the Bee Gees arrives at the World Music Awards in Monte Carlo May 18, 2010.

Robin Gibb of the Bee Gees has astounded doctors by waking from a coma over the weekend, but has since been diagnosed with colorectal cancer.

The 62-year-old is currently still in intensive care, his doctor reported Sunday.

Dr. Andrew Thillainayagam said that Gibb is being treated for advanced colorectal cancer and added that the singer is "exhausted, extremely weak and malnourished," according to the Associated Press.

Gibb has battled illnesses over the past year that include a severe case of pneumonia and colon cancer, but has beat the odds and is fully conscious and able to speak after waking from the coma.

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

Last week, many reports indicated that the "How Deep Is Your Love Singer" was in grave condition.

"Sadly the reports are true that Robin Gibb has contracted pneumonia and is in a coma," said a statement on the singer's official website. "We are all hoping and praying that he will pull through."

Following the hospitalization and grim news, Gibb's son, Robin-John Gibb, shed also some light on the singer's condition.

"My dad has had a hard recovery from cancer," Robin-John was quoted as saying by the Daily Mail. "When you rid of the cancer a lot of periphery problems can occur. This is so sad."

Gibb was forced to undergo intestinal surgery last month as well, but his health appeared to be looking up.

In 2003 Maurice Gibb, Robin's twin brother, died at age 53 of a twisted colon caused by a congenital defect that Robin also shares. While the intestinal issue is not directly related to his previous colon cancer, Gibb's health is still in danger.
