Cancer sure is tricky. We try to starve it, cut it, stress it out of our bodies. We even bombard it with radiation until it dies. And yet, not due to lack of trying, many times we lose the fight. It escapes, evades our resistance. Its overly mutational nature leads it to adapt, dodging the deadly effects of chemotherapeutics. Not only that, but the lack of selectivity in many treatments means that while we harm the tumour, we also wreak havoc to our own healthy cells. It makes the battle much harder.
