We talk about preventing cancer. We talk about treating cancer. And we talk, endlessly, about “the cure.” Yet what is rarely addressed in all of our conversations about cancer is what happens after cancer. As a Wall Street Journal story this week explains, cancer, for all the damn attention we give it, is in many ways a still vastly ignored and underestimated experience. That’s why a new movement in medicine is afoot, with the goal of helping patients deal with the side effects and long-term physical and emotional after-effects as they transition back to health. Commission on Cancer chair Dan McKellar calls this next step “an absolutely essential part of cancer care.” Call it cancer rehab — a notion that’s been far too long a time in coming.
