When Darline Miller got breast augmentation surgery 16 years ago, she wanted to fit in with a culture that prized women’s large breast size. She went up from her natural “B” cup to a fuller “C” 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 didn’t reveal “too much side boob.” Her breasts got in the way of her golf swing. She also worried breast implants might pose long-term health risks.

“I was at that point in my life that I didn’t need any more hassle,” said the 45-year-old San Diego resident, who works as a property manager. “When I first got them, I wanted to conform. Now that I’m in my 40s, I just want to be me.”
