In my first full day after chemo there were absolutely no noticeable side effects. I was expecting some nausea, but it never happened, thankfully. Cancer treatment has improved so much in the last decade that people who meet me have difficulty believing that I have Stage 4 Lung Cancer. Of course, this new journey of mine has just begun, and, of course, we have no idea at this point that these drugs are doing anything to reverse my cancer, but so far, so good.
