“The difficulty lies not so much in developing new ideas as in escaping from old ones.”
Cancer is deadly because of its propensity to spread, or metastasize. Cancer is deadly because it moves, not because it is big. Cancers that don’t metastasize are called “benign” because they very rarely cause significant disease. Cancers that do metastasize are called “malignant” because of their tendency to kill.
Surgery for cancer is performed to prevent metastasis, not because the cancer is too big. A cancer medication’s ability to shrink a tumor is immaterial to overall patient survival. A drug that destroys half the tumor is no better than surgery to remove half the cancer—in other words, almost completely useless. Getting half the cancer is no better than getting none of it.
Cancer is originally derived from our own cells but develops into an alien species.
