Biden has surgery to remove skin cancer lesions

• Biden's office announced in May that he was diagnosed with an aggressive form of prostate cancer.

What they're saying: "Former President Biden recently had Mohs surgery," Scully said in the statement, without elaborating further.

• Scully did not immediately respond to Axios' request on Thursday evening for more details on the surgery and the former president's current condition.

Zoom in: Mohs surgery is "the best method of removing skin cancer," according to a Skin Institute post.

• It is most useful for patients who have a high risk of cancerous lesions returning after previous treatment in areas such as around the eyes, ears, nose, mouth, hands, feet and genitals, per a Mayo Clinic post.

How it works: The surgery "involves cutting away thin layers of skin," according to the Mayo Clinic.

• "Each thin layer is looked at closely for signs of cancer. The process keeps going until there are no signs of cancer," per the clinic's post.
• "The goal of Mohs surgery is to remove all of the skin cancer without hurting the healthy skin around it."
