You might think that fibrocystic breasts have the C-word written all over them. But in reality, they are benign—so having them doesn’t mean you have cancer, and it doesn’t up your chances of developing cancer, either.
It is important to know that having fibrocystic breast changes does not increase your risk of breast cancer, said Nicole Zaremba, M.D., breast oncology surgeon at Aurora Health Care in Milwaukee.
Many women with fibrocystic breasts have a history of multiple benign solid breast masses.
However, Zaremba continues, women with fibrocystic breasts sometimes [but not always] have dense breasts, and women with high-density breasts are four to five times more likely to develop breast cancer than women with low-density breasts.
Therefore, it is important to distinguish benign breast lumps from potentially cancerous or malignant breast masses, which is done with breast imaging, like a mammogram and/or ultrasound.
