The 35-year-old dancer decided on the surgery due to her daily fear of her breast cancer returning, following her initial diagnosis in May 2023.
Dowden had confirmed last month that she would be undergoing the procedure after consulting with her medical team.
She expressed her strong desire to return to the dance floor, hoping to participate in a small capacity during the Strictly final before the year is out.
“I’d love to be back dancing a little bit in the Strictly final,” she shared.
