Joe Biden undergoes surgery to remove skin cancer

Former US president Joe Biden, aged 82, has had surgery on his face to remove skin cancer lesions.

Spokesperson Kelly Scully confirmed the operation after Mr Biden was filmed leaving a church in Delaware with a fresh scar on his forehead.

Mr Biden received Mohs surgery, a procedure used to cut away areas of skin until the cancer is completely removed.

In March, Mr Biden's office announced he was diagnosed with an aggressive form of prostate cancer with tests revealing the cancer had spread to his bones

Prostate cancer is assigned a Gleason score, which ranges from two to 10 and indicates how abnormal the cancer cells are when compared to healthy tissue under a microscope.

Mr Biden’s office reported his score was nine, suggesting a highly aggressive form of the disease.

"Cancer touches us all," Biden wrote on social media at the time. "Like so many of you, Jill and I have learned that we are strongest in the broken places."

While he was in office, the former president had a lesion removed from his chest.

The lesion was a common form of skin cancer, a basal cell carcinoma.
