Donaldson’s mother spent long hours in the car and out of town caring for her grandmother. A few years later, her other grandmother was diagnosed with cancer. Planning a child’s birthday party was the ball Donaldson’s mother dropped as she juggled responsibilities.Karen Mallory knows what’s like to have children lose their sense of normalcy.Four and a half years ago, Karen’s husband was diagnosed with prostate cancer. Six months later, Mallory was diagnosed with lobular breast cancer. Her children were 9 and 10 years old at the time and witnessing both parents experience chemotherapy, radiation and surgeries.Now the Battle Ground women are using their experiences with cancer — Donaldson was also diagnosed with skin cancer in 2006 — to help other families struggling with disease.After months of planning, the duo launched the Celebrate Me Foundation in January. The website (http://www.celebratemefoundation.org) went live in June. And in August, the organization began accepting applications for services.The crux of the foundation is simple: provide children who are experiencing cancer with a birthday party, a break from cancer diagnoses and treatments.
