But the pop legend WILL be fit to perform his £150million comeback gigs at London’s O2 Arena from July. And aides say he is looking forward to the 50 sell-out shows — amid predictions they will be his most spectacular ever.
A source said: “Michael’s tests showed spots of skin cancer on his body, and cells which could turn to skin cancer on his face.
“Michael is really looking forward to his concerts and is determined to wow his fans at each and every gig.
“He said he’s insisted that any treatment must fit around the concerts, and the show will go on.”
Jacko, who has been seen making regular visits to his Beverly Hills dermatologist wearing a mask and surgical cap, received the shock diagnosis last month.
He was seen on April 22 at Cedars-Sinai hospital in Los Angeles, which has a specialist lab to test for such diseases.
The star’s Escalade motor was involved in an incident as it arrived to pick him up.
It is believed Jacko will be treated by Cambridge-educated Dr Ralph Massey, an award-winning cosmetic and skin cancer surgeon based in Santa Monica.
It is thought the star’s condition may be linked to his vitiligo, a disease that affects pigmentation.
The US Federal Drug Administration has previously warned of a risk of skin cancer from skin bleaching treatments.
While Jacko strongly denies ever using skin bleaching products, an eBay sale claiming to be of his belongings last year included a used tube of the cream.
Jackson has promised organisers of his eagerly-anticipated 02 gigs that he is fully fit to perform — and is believed to have passed a series of medical tests.
He is currently involved in intense rehearsals in LA — working through gruelling dance routines for the two-hour-plus concerts in his This Is It tour.
They will feature more than 22 different sets, numerous costume changes — and a dance move to rival his famous moonwalk.
Jacko’s closest aides insist he is in good health and looking forward to the concerts.
Business manager Dr Tomhe recently said he had only taken time out of the spotlight to care for his children — Prince, 11, Paris Katherine, ten, and Prince Michael II, five.
Speaking after Jackson appeared at a London press conference to announce his concert dates, Dr Tomhe said: “He’s come back to put an end to all the bulls*** rumours about his health.
“I think he has answered his critics. He is back to his old self - he’s fine, and couldn’t be in better shape. He was away for all this time because he was dedicating his life to his children and being a single parent.”
Tomhe is adamant that Jackson will use his comeback concerts to prove his doubters wrong.
He added: “It was his idea because he misses his fans and his fans have missed him.
“He is very excited and the shows this summer are going to be more spectacular than ever before.”
Concert promoters AEG Live International insist the star had passed a full medical before signing for the live shows.
Company president Rob Hallett said: “He’s fitter than I’ll ever be. His cholesterol levels, his blood, everything was perfect and we got the insurance.”
Paramedic Jamin Mauro and his partner were idling outside the hospital when a black Cadillac Escalade hit their ambulance, knocking off a mirror.
The driver then walked to the hospital doors with an umbrella and met Jacko, Mauro said.
The car is said to have driven away after the star jumped in. Beverly Hills cops acknowledged the collision. Mauro said he and his partner were upset the driver did not wait to swap details.
Mauro said: “I don’t know if Jackson told him to leave or not, but they should have stayed.”
Earlier this year we revealed the star, who has had a string of health problems, had been treated for an MRSA-style skin infection.
He denied earlier claims by his biographer Ian Halperin he was suffering from a lung disease.
He was treated for back pain during his 2005 trial, when he was cleared of child molestation charges.
A RECORD 242 students simultaneously performed Jacko’s Thriller dance routine in Williamsburg, Virginia.
