oncology.basically-- working with our body's immune system to destroy cancer cells. benefitting patients like mary mannion. 3 mary mannion's skin cancer was first detected on her leg. "i think it's right here." a

faint scar lingers. "i had a mole that changed shape, size, color."stage four melanoma.surgeons removed it and mary underwent targeted therapy. eleven years later - -- the cancer came back. "the melanoma had metastasized here." most melanomas start
