Q. What are the risks of C-section? See that all the pregnant movie stars are having C- sections instead of natural child birth. Maybe I should have one too, instead of giving birth regularly? Are there any risks?

Q. How is a C-section done? My wife is expecting twins and her Doctor scheduled a C- section for her. How is it done?
