By the time she was diagnosed months later, the cancer had spread.
"I left it too late. I knew something was kind of wrong, but I didn't think it was cancer, and I didn't check for lumps."
She began a year of chemotherapy and radiation. Last year, while undergoing more radiation treatment, she learned she was pregnant.
Mrs Doolabh made the courageous decision to stop treatment until after she gave birth, even though it allowed the cancer to spread further.
Her third child, Matthias, meaning "God's gift" in Hebrew, was born to her and husband Aneal two days before Christmas.
Mrs Doolabh shared her journey online, inspiring some of the 16,000 Facebook followers to get checks.
"I'm dying at the moment, and I've got three beautiful children and a husband I'm leaving behind. It's just so important to check your breasts."
New Zealand Breast Cancer Foundation spokeswoman Adele Gautier said women needed to report any changes to their doctor and those over 40 needed regular mammograms.
