The 36-year-old was diagnosed just before last Christmas but his club made the news public in January.
Bamba underwent several rounds of chemotherapy and this month returned to action as a late substitute in Cardiff’s home draw with Rotherham on the final day of the Sky Bet Championship season.
In a heartfelt message on Twitter, Bamba said: ‘Hey everyone, just a quick message to inform you that I’m now cancer-free! It is of course incredibly heart-warming news for my family and I, we are over the moon right now.
‘I really want to thank each and everyone that has been supporting me, whether it’s been with a comment, a message, a like or whatever, that definitely gave me extra strength to go through this.
‘Above all, I want to thank the family at the NHS who took such good care of me, I will always be grateful for your job.
‘Thank you to all my family, my friends, and of course the club and everyone in the football industry that has helped me facing this challenge.
‘I wish you all a blessed day and hopefully will see you soon again on the pitch. Sol.’
Bamba, who started his career at Paris Saint-Germain, made seven appearances for the Bluebirds this season and 117 in total, scoring 10 goals.
He helped the club into the Premier League in 2018 and has also had spells at Hibernian, Leicester and Leeds United.
