But I feel too healthy to have cancer...
We finally got liver needle biopsy results today, and it is ER+, HER2- breast cancer that has set up shop in her liver. I spent the past week listening to my wife say that she feels too good for it to possibly be metastatic cancer. I understand the confusion and frustration of it. She feels great, yet there is a potentially deadly disease process growing within her. Think about it like an actual disease. Imagine you are treating a patient with Ebola. You accidentally stick yourself with a dirty needle. There is no question -- blood with Ebola got in through the puncture, and you now have Ebola. Except that you feel fine. There is an incubation period, and you feel perfectly healthy. That's what early stage metastatic cancer can be like -- except that unlike Ebola there are many drugs that can slow the progress and mitigate the effects.
