Why Is It So Hard to Find a Cure for Cancer?

Finding the cure for cancer is about as sought after as any elusive treasure. But there’s a reason nobody’s found it yet: Cancer isn’t actually a singular disease, but a broader genre of affliction, like viral infections. As much variation as there is between humans in their normal DNA, there’s even more genetic variation between any two types of cancer. That doesn’t mean researchers aren’t hard at work to figure out the best therapeutics possible and yes, even cures, for cancers.
