Washington, Mar 4 (IANS): A cancerous skin lesion had been removed from US President Joe Biden's chest, White House physician Kevin O'Connor said.

O'Connor wrote on Friday in a memo that the tissue was removed as part of Biden's health assessment at a military hospital last month and sent for a traditional biopsy.

"As expected, the biopsy confirmed that the small lesion was basal cell carcinoma. All cancerous tissue was successfully removed," O'Connor added.

"No further treatment is required."

Basal cell carcinoma is the most common form of skin cancer and the most frequently occurring form of all cancers, according to the Skin Cancer Foundation, Xinhua news agency reported.

Basal cell carcinoma lesions do not tend to "spread" or metastasize, O'Connor said, adding that "they do, however, have the potential to increase in size, resulting in a more significant issue as well as increased challenges for surgical removal".

"The site of the biopsy has healed nicely and the President will continue dermatologic surveillance as part of his ongoing comprehensive healthcare," the White House doctor noted.

Biden, 80, had his annual physical exam two weeks ago. O'Connor announced later that he "remains a healthy, vigorous, 80-year-old male" who is fit to carry out the duties of the presidency.
