If you had cancer, how good would a treatment have to be, how much would it have to help, for you to use it? How about if it gave you a 5% better chance of cure? A 10% chance? How about a 20% chance to be beat the disease using a treatment without side effects that is free? “Sign me up,” you say? Nonetheless, only 8% of breast cancer patients use a therapy that has a 25% likelihood of curing them of the dread disease? Ridiculous? Yes, but true.
