Charles Manson is finally strong enough to undergo a surgery that will repair a lesion in his intestines that has caused significant bleeding ... TMZ has learned. TMZ broke the story ... Manson was rushed almost a week ago from Corcoran State Prison to a hospital in Bakersfield, CA for an operation. We're told Manson refused the surgery, but on Thursday had a change of heat. Hours before the scheduled operation, doctors determined they couldn't put the 82-year-old under and operate because he was too weak ... so the surgery was scrubbed.
