I'm a pretty healthy person. I believe in preventative care, and I have a physical and full blood work done every year. So far I haven't had any serious illnesses, or had any other concerns, so I kinda take my excellent health for granted.
Over the summer, about a month before my birthday, I went in for my well woman exam. My doctor recommended that I get a mammogram. "But I'm not 40!" I screamed. She laughed and explained that she'd like to get a baseline test well before I turned 40, so that any changes in my breasts could be immediately identified when I do start getting regular mammograms *cough* in four years.
