When JoAnn Pushkin was 45 years old, she felt a lump in her right breast—which struck her as odd, considering it had only been eight weeks since her annual mammogram, which she’d been getting dutifully since the age of 40, and which had produced a result of “normal.”
Pushkin went to her doctor, who felt the lump and sent her for another mammogram plus ultrasound. She was surprised when the technician told her, offhandedly, “You have dense breasts. This is going to be a very hard find for us.”
