A new study has found that women with dense breast tissue and no lobular involution - an age-related change in breast cancer tissue - are at an increased risk of developing breast cancer.
According to HealthDay News
, researchers at the Mayo Clinic and the National Cancer Institute studied 2,666 women between the ages of 18 and 85 that had been diagnosed with benign breast disease. They were followed for an average of 13.3 years.
"Our findings also reveal that having a combination of dense breasts and no lobular involution was associated with higher breast cancer risk than having non-dense or fatty breasts and complete involution," researchers said in a press release.
Other factors that play a role in developing breast cancer include a patient's age, medical history, family history and the age at which they had their first menstrual cycle.
The chances of a woman developing breast cancer in her lifetime are one in eight in the U.S., according to the American Cancer Society.
