French Prime Minister Michel Barnier underwent surgery on a cervical lesion over the weekend, his doctor said in a statement shared by Barnier's office on Monday, Paralel.Az reports citing Reuters.

The operation went well and Barnier, 73, resumed work on Monday, the statement said. Results from an analysis of the lesion will be known in several weeks.

A lesion is an area of an organ or tissue that has been damaged through injury or disease, such as a wound, ulcer, abscess or tumour. A spokesperson for Barnier's office declined to comment when asked if there was any suspicion of cancer, citing medical confidentiality.
