When Jennifer Marrone of San Diego, CA, was diagnosed with stage IV colon cancer at age 30, she didn't just want to know what her treatment options were. "I wanted to know how they were going to affect my life," says Marrone, who's now 35. She was pleased when her oncologist at UC San Diego Health gave her several suggestions for medications and lifestyle changes, like adopting a diet free of animal protein. He also had copies of research studies to back up each potential therapy and treatment.
