The 43-year-old presenter announced in October that she was undergoing treatment for stomach cancer and later had a tumor removed by surgery.
She now uses an ostomy bag, which attaches to her abdomen and has also undergone chemotherapy.
Roberts spoke about staying mentally strong throughout her treatment during a photoshoot with Women’s Health UK.
She said: “Being diagnosed with cancer means that I have learned to appreciate my body; be thankful it works; be thankful they found the tumor in time to remove it and be thankful (that modern medicine means I can) have a stoma.
“I feel like I love my body more than ever.”
Addressing the importance of talking about cancer, she said: “One in two people will be diagnosed with cancer at some point in their life and I think the more we can talk about it, the less people will be negatively affected mentally, if and when that happens.
“That’s why it means so much – as someone undergoing cancer treatment and with a visible stoma – to be on the cover of Women’s Health.”
Roberts admitted she spent a lot of time feeling ‘shattered’ by her diagnosis and added: ‘When I was in the hospital recovering from my operations, I would overhear the conversations of other people. women in the ward and I learned that they had a much worse diagnosis than me – possibly terminal cancer – and that’s where I felt depressed.
“I think my strategy, so that I can stay stable while I’m on chemotherapy, is to just keep going and try not to get beat up mentally.
“Like, I kind of have to tackle it head-on, because that’s how I handle things, but I understand that everyone is different.”
Roberts, who is bisexual and an LGBT rights activist, also remembers meeting her partner Kate for the first time.
She said: “I remember seeing her and thinking she was beautiful, but I didn’t know she was gay; then she mentioned she was going on a date with a woman and that was it, she couldn’t get rid of me!
Claire Sanderson, editor of Women’s Health UK, hailed Roberts as a role model.
She said: “Wellness should always be an inclusive space and what better way to embody that than to have someone as inspiring as Adele on the cover of Women’s Health.
“It’s an uplifting and joyful image, full of positivity and spirit.
“Adele is truly a role model, not just in the wellness world, but for all women who have had to deal with serious illnesses like cancer.
“His mental toughness – aided by talking with others and staying physically active – is quite incredible.
“It has been a privilege to post and we are incredibly proud to help Adele tell her story.”
