DUSTIN HOFFMAN’s reps announced that the “Tootsie” star’s been “surgically cured” of cancer, but experts tell The ENQUIRER the beloved actor is still facing an uphill battle.

The mouthpieces for the legend­ary actor, 76, didn’t reveal the type of cancer, but a news exclusive on Aug. 8 reported that the disease had attacked Dustin’s throat.

 A rep for Hoffman subsequently denied that Hoffman has throat cancer.

The actor’s team said the two-time Oscar winner is undergoing “preventative treatment” so the disease doesn’t return – and that set off alarm bells for our experts.

“You can’t say it was cured if he is receiving additional treatment,” said noted New York head and neck oncologist Dr. Marshall Strome, who has not treated Hoffman.

And West Palm Beach, Fla., radiation oncologist Dr. Jerome Spunberg, who also has not treated Hoffman, says head and neck cancers can be “deadly” without treatment and easily spread.

Dustin’s being brave, and a Hollywood source said one of the first people he turned to after his diagnosis for comfort and advice is longtime friend and “Meet the Fockers” co-star Barbra Streisand.

“Barbra’s like family,” the source added. “She’s been there for him in a big way.”
