Study: Chemo can backfire, make cancer worse

kgo
By ABC7

Researchers found that chemotherapy can cause healthy, wound-healing cells around tumors to "go rogue" and produce a protein that helps the cancer resist chemo. About 90 percent of patients develop chemo resistance when being treated for cancers that can spread, such as breast, prostate, lung, and colon cancers.

That study appears in the journal "Nature Medicine."
