When Angela Hanslip was told she had breast cancer 13 years ago, she felt as though her doctor had given her a death sentence.
The news was followed by tears and a gruelling treatment program that included six months of chemotherapy and 35 radio-therapy sessions.
But while Mrs Hanslip knew her life would never be the same after the devastating diagnosis, she did not expect that the biggest change would come months after her treatment ended.
"The following year I went to visit my sister who was living in Spain at the time and I was really tired and out of sorts," she said. "It turned out I was five months pregnant and had conceived my son within three months of finishing treatment."
Mrs Hanslip was one of about 4880 people who helped raise awareness and funds for breast cancer research by participating in the Mother's Day Classic fun run.
While husband Steve watched their son Nicholas, 11, Mrs Hanslip walked around Langley Park in Perth and shared her experience with others.
The Mother's Day Classic was held across Australia yesterday and was expected to raise more than $4 million for the National Breast Cancer Foundation.
