Washington, July 4 Late King of Pop Michael Jackson has a cancerous lesion removed from his nose just weeks before his death, says biographer Diane Dimond.

"Last week, I had two real sources call me and say he's getting surgery right now for removal of skin cancer off his nose," Usmagazine.com quoted Dimond as saying.

"This is not a man who suffers pain well. He likes painkillers. So he got some from here, he got some from there-who knows how much," she added.

According to sources, the 'Thriller' hitmaker was also suffering from persistent insomnia in recent months.

"For the past 15 years, Michael always slept until 3 or 4 in the afternoon and was up all night. When he started rehearsals for the tour, it totally screwed up his system," said a source.

The source added that Jackson began adding stimulants to his daily drug regimen in order to rise earlier. (ANI)
