American tennis star Serena Williams revealed on Wednesday that she had a grapefruit-sized cyst removed from her neck and is recovering well from the surgery. The 43-year-old former world number one shared a video on TikTok, explaining that she discovered the lump in May and that an MRI confirmed it was a benign branchial cyst. "Health comes first," she emphasized. #serenawilliams,#tennisupdate,#healthrecovery
