As cancer care evolves and new treatments help more people survive and thrive after a cancer diagnosis, a related medical subspecialty is evolving alongside. Called cardio-oncology, this relatively new field of medicine specializes in the diagnosis and treatment of cardiac problems caused by common cancer drugs.

A little girl has just been diagnosed with cancer, and her parents are facing a new and terrifying reality. Whys and what-ifs dominate their thoughts, and a feeling of helplessness threatens to overwhelm them. They would suffer the disease for her if they could, but they can’t. They would do anything for this to be over, for her to be OK.

Children as young as 3 can be clinically depressed, and often that depression recurs as kids get older and go to school. It also can reappear during adolescence and throughout life.

My story is about neuroplasticity and mayonnaise. I spent the greater part of my 20s living in Dublin, where I was working on a doctoral thesis in history and where mayonnaise comes in glass jars.

For the most part, I did my moving on my back and on my own.
