Dowden said she is undergoing physio for her injury and can walk on it, with doctors hopeful she could be dancing again by December.
It has been a bout of bad luck for the Caerphilly-born dancer, as she fractured her foot soon after finishing chemotherapy.
She said the recent injury is "totally different injury to the previous one" which she said could have happened to anybody.
"The doctor is saying I could be back dancing by the end of November so that’s what is keeping me going," she said.
"I am focusing on that, focusing on getting back on the dancefloor with Carlos and coming to Wales for our tour in Cardiff."
Dowden and fellow professional Carlos Gu kick off their Reborn UK tour in March next year, with two nights at the Welsh capital.
