When Darline Miller got breast augmentation surgery 16 years ago, she wanted to fit in with a culture that prized womenโ€™s large breast size. She went up from her natural โ€œBโ€ cup to a fuller โ€œCโ€ on her petite frame.

But about a year ago, Miller was tired of her bigger chest. It was a pain shopping for supportive running bras or bikini tops that didnโ€™t reveal โ€œtoo much side boob.โ€ Her breasts got in the way of her golf swing. She also worried breast implants might pose long-term health risks.

โ€œI was at that point in my life that I didnโ€™t need any more hassle,โ€ said the 45-year-old San Diego resident, who works as a property manager. โ€œWhen I first got them, I wanted to conform. Now that Iโ€™m in my 40s, I just want to be me.โ€
