Recent studies have shown the number of women giving birth by C-section has been growing. Now a new study casts doubts on whether they're being done for the right reasons. ABC News reports medical necessity, not financial factors should drive any decision on whether to have a C-section but a consumer reports study found that some hospitals have far higher c-section rates. Doris Peter, director of the Consumer Report Health Rating, says they can be more profitable for hospitals but are riskier for women, "once you've had a C-section, you are 90 percent more likely to have a second one, and as you have multiple C-sections, your risk of complications go way up." She says wildly different rates, ranging from 4 percent to over 50 percent, can be hard to find out, but should be brought to light to arm women with life-saving information.
