The mum-of-two shared her concerns for her children this week.

Michelle Heaton has opened up about learning she had the BRCA2 gene at a Stand Up To Cancer charity event. The mother-of-two underwent a double mastectomy and a hysterectomy after she was told she carried the gene in 2012 to lower her chances of developing cancer. However, speaking at a charity event this week, Michelle says she now fears that she may pass the gene on to her children.

“Taking part in the Great Canoe Challenge was a no-brainer for me,” she said at the Stand Up To Cancer event. “When I discovered I was a carrier of a faulty version of the BRCA2 gene, it was devastating. “I felt like my world had been turned upside down.”

The mum went on to say that the thought of her children having the gene is a daily one.

“It’s really hard to say that I think about this every day, but I do. “I know that I’ve got a 50 percent chance of giving it to my children, and it’s really heart-breaking to think that my daughter might have to make those decisions before she’s even started a family.”

However, Michelle says she is determined to fight by taking part in events like this one, saying:

“I want to do everything I can to help to raise money for research because I know it’s the key to defeating this disease. “We can help stop cancer before it stops my children.”
