Michael Schumacher is to have stem cell surgery in the next couple of days, according to Italian media.
The 51-year-old suffered a brain injury while skiing in the French Alps with his family nearly seven years ago.
The seven-time world champion (a record) was induced into a coma after suffering the injury, and although he came out of the coma six months after the accident, his health has been kept extremely private since the accident.
The operation will be performed by French professor and cardiologist Dr Philippe Menasche, who stated that: "The goal is to regenerate Michael's nervous system."
Speaking to French newspaper Le Dauphine, neurosurgeon Dr Nicola Acciari explained: "The goal is to regenerate Michael's nervous system.
"Over the past 20 years, science has made enormous progress with stem cell treatment. But that does not change that we still do not know much about the human brain."
In September 2019 Schumacher underwent treatment at Georges-Pompidou hospital involving transfusions of inflammation-reducing stem cells, also performed by Menasche.
Schumacher's management declined Yahoo Sports' request for comment.
