I have a few friends who have had breast cancer. Some of them had chemo, and some had radiation.those who had radiation did not lose their hair, and seemed to have less health issues after treatment. Of those who lost their hair, one had it grow back fine, and one had some permeant hair loss. So I can believe Maggie can jog regularly and has beautiful hair after breast cancer.
BTW, the one constant with my friends different experiences with cancer is the FEAR. It’s terrifying to think about dying and about what your life will be like afterwards if you live. The words just don’t exist for me to express how much cancer sucks. So Maggie’s fear of treatment and perhaps paralysis about making a decision seems very realistic to me. The not unpacking is also familiar.
