Apparently just one study, but this doesn't sound good.
You'd think that a tumor shrinking would be considered good news for anyone suffering from cancer. But maybe not. Scientists have found that a type of cancer treatment aimed at shrinking tumors can actually make them spread more efficiently and kill patients quicker. . . .
In plainer terms, big tumors are less likely to spread, which is pretty disturbing. I've had several family members who died at the hands of cancer shortly after the "good news" that doctors had "shrunk the tumor!" Was that tumor shrinkage actually what killed them?
