Denser breasts have been shown to have a higher risk of developing breast cancer, according to recent studies. Not only does breast density increase the risk of breast cancer, but it also makes it more challenging for medical professionals to detect cancer in mammograms.
Dr. Rebecca Wiatrek, a surgical oncologist with Texas Oncology, emphasizes the importance of understanding the relationship between breast size, breast density, and the different stages of breast density. Breast density refers to the amount of breast cells compared to fat cells in the breast. For example, some women may have smaller, compact breasts with extra breast cells, while others may have mostly fatty tissue in their breasts.
There are four stages of breast density, ranging from breasts with mostly fat to extremely dense breasts. Stage one breasts consist mostly of fatty tissue, while stage two breasts have scattered fibro glandular tissue. Stage three breasts have more dense breast tissue, with pockets of denser areas, and stage four breasts are extremely dense, making it difficult to see abnormalities in mammograms.
The reason why dense breasts have a higher risk of cancer is still not fully understood. While it was once believed that the masking effect of dense breasts in mammograms was the cause, newer studies suggest that it is related to the number of cells in the breasts that may turn into cancer.
To determine if you have dense breasts, it is essential to undergo a mammogram, as it is the standard method for assessing breast density. The FDA has recently updated regulations to ensure that patients are informed about their breast density during mammography screenings. Dense breast tissue may feel different during self-exams and can sometimes be mistaken for masses.
Mammograms and breast screenings are crucial for detecting cancer early and determining the appropriate care for patients. It is generally recommended to start mammogram screenings at age 40, unless otherwise advised based on individual risk factors. Clinical exams and screenings should begin at age 25, with guidance from healthcare providers.
Overall, understanding breast density and its relationship to breast cancer risk is essential for women’s health. By staying informed and following recommended screening guidelines, women can take proactive steps towards early detection and effective treatment of breast cancer.
