A lesion on President Biden’s chest removed during last month’s annual physical exam was a basal cell carcinoma, and all cancerous tissue was successfully removed, his doctor said Friday.

Kevin O’Connor, the president’s physician, wrote in a memo that a biopsy confirmed the small lesion was basal cell carcinoma, one of the most common types of skin cancer. The area was treated at the time of the biopsy and no further treatment is required, O’Connor wrote.

“The site of the biopsy has healed nicely and the President will continue dermatologic surveillance as part of his ongoing comprehensive healthcare,” the doctor wrote.

This developing story will be updated.
