In May of 2002, Sharlene Kirby was diagnosed with a rare and aggressive form of breast cancer — inflammatory ductal carcinoma. It was determined to be at stage IIIB, meaning it had either spread to tissues near the breast (skin or chest wall, including the ribs and the muscles in the chest) or to lymph nodes inside the chest wall along the breast bone.

Kirby was basically given one treatment plan as an option — four treatments of chemotherapy, a mastectomy, then more chemotherapy. But after three treatments of chemo, she had a bad reaction to one of the drugs used. This scared her and sent her to seek out possible alternatives.
