Kelly Osbourne and Sharon Osbourne are encouraging women to sign up for Race For Life this year

Posing as warriors, Kelly Osbourne and Sharon Osbourne team up to fight a disease that is close to their family.

The mother and daughter duo posed for a photoshoot to encourage women to sign up to Cancer Research UK’s Race for Life events this year, after their own personal experiences with cancer.

Kelly, 30, revealed in March that she has tested positive for the BRCA1 gene – like Angelina Jolie – putting her at high risk of getting breast and ovarian cancer.

Sharon, 62, won a battle with colon cancer 10 years ago but the former X Factor judge revealed in 2012 that she had had a double mastectomy to remove both her breasts as a precaution after she was warned she also carried the faulty gene.

The mum-of-three said she was ‘honoured’ to be supporting Race for Life this year.

She said: ‘As a cancer survivor myself, I know it takes all your strength and the support of your family and friends to overcome this disease.

‘I’m asking every woman – mother, daughter, grandmother, sister and auntie in the UK to step forward and unite to defy cancer. Let’s show cancer that hell hath no fury like a woman in pink.’

Kelly added: ‘After watching my mum go through colon cancer and the recent news that I’m carrying the BRCA1 gene, just like my mum, I wanted to show my support for Cancer Research UK’s Race for Life.’

Kelly made the revelation she had the BRCA1 gene on American TV earlier this year while she was discussing Angelina’s brave decision to have her breasts and ovaries removed to narrow her chances of getting either of these cancers.

Kelly said: ‘I agree with this one hundred percent. I know one day I will eventually have to do it too. If I have children I want to be there to bring them up.

‘I have been the child a child of a cancer survivor and being on that end as well has been really hard to deal with. I’m so lucky to have the brave mother I have.’
