A New York physician was busted Wednesday for putting his mouth on a patient’s breast during a cancer-screening exam.

Primary care doctor Mark Jackson, 58, allegedly performed the unorthodox act Sept. 15, 2017, while employed at the Star Treatment and Recovery Center in Harlem.

“The defendant placed his mouth on her right breast and grabbed her hand and placed it on his penis and stated in sum and substance: Do you see how hard you got me?” court papers say.

Jackson, wearing, glasses, a Ralph Lauren plaid shirt and navy slacks, nervously stood before Judge Joanne Watters as he was arraigned Wednesday in Manhattan Criminal Court on two counts of sex abuse and one count of forcible touching.

Manhattan Prosecutor Matthew McCarthy said that Jackson “betrayed the trust of his patient and sexually abused her while she was seeking a simple cancer screening.”

In a Dec. 1, 2017, meeting with investigators, Jackson insisted the doctor’s visit was above board. “During the breast exam, I only touched her with my hands,” he allegedly said, according to prosecutors.

He admitted to authorities that he later called the patient at home — but only after “she wrote her number on a piece of paper, handed it to me and said call me sometime. I told her I would do that.”

This wasn’t Jackson’s first brush with the law. In 1996 he was convicted of distribution of a controlled substance in Manhattan federal court and was sentenced to one year in prison.

Legal Aid lawyer Jin Wu said that Jackson is still practicing as a physician but didn’t specify where. He added that his “client denies the allegations.”

The judge ordered Jackson held on $1,500 bail and issued an order of protection in favor the victim.

He’s due back in court Aug. 27.
