One more reason to purge your kitchen cabinets of recyclable plastics marked with the number 7 and cut back on the canned goods: BPA, which may be an ingredient in plastic containers, and which is also found in the linings of most canned food, may interfere with chemotherapy.
The New York Times Well blog reports that cancerous cells of animals exposed to BPA did not react as expected to chemotherapy. The cancer cells should have died. But instead, the presence of BPA seems to protect cancer cells from radiation treatment.
This is not good news, and it's one more reason to reexamine your intake of canned food and beverages from polycarbonate bottles.
