Former world number six Carla Suarez Navarro says she is responding "very well" to cancer treatment and "dreams" of returning for one last major event - this year's Tokyo Olympics.
Suarez Navarro posted on Twitter on Monday that she was having her last chemotherapy session.
"I don't want people to remember me in a hospital bed, so I'd like to go again into a big tournament," she said.
"It would be a dream to do that - an Olympic Games to say bye to my tennis family and also all my tennis fans."
Suarez Navarro, who had previously planned to retire in 2020, said she has discussed teaming up with Garbine Muguruza, her doubles partner at the Rio 2016 Olympics.
