She also spoke about how important it was to have a goal to work to.
“I say that to anybody who’s got a new diagnosis,” Dowden said.
“Whether it’s working towards a holiday, returning to work, a visit in some way or whatever it is – have that little goal to really push yourself.”
She added: “I used to tick everything off – every chemo, tick; every blood test appointment, tick; every oncologist [and] rescan – everything was a little tick along the way.”
Dowden underwent treatment for stage-three breast cancer in 2023.
Following chemotherapy treatment and a mastectomy, she announced in February that tests showed she had “no evidence of disease”.
She said the pair hoped audiences would find their new show uplifting and inspiring, adding: “I hope to show them my motto.”
“Don’t get bitter, get better.”
