In this Thursday, Feb. 9, 2012 photo, Caroline Swain poses for photographs with her sons Max, left, 10, and Luke, 9, at their home in Rayleigh, England. Swain was diagnosed with breast cancer while pregnant with Luke. She had her left breast and many lymph nodes removed and had to wait until her fetus was 12-weeks-old before starting chemotherapy. Researchers have encouraging news for women who have cancer while pregnant. Studies suggest that these women can be treated almost the same as other cancer patients are, with minimal risk to the fetus. (AP Photo/Matt Dunham)
