Omega-3 and breast density


A mammogram is an X-ray picture of the breast that allows to detect changes in breast tissue that cannot be felt during a breast exam (the radiologist compares your past mammograms with your most recent one to check for changes). When to start and how often to have a mammogram must be decided by your doctor, depending on your individual characteristics (age, among others). What it is important is to control changes. That is why it is important to get regular checkups.

Breast density, which can be only seen in mammograms, is categorized into four degrees, from almost all fatty tissue to extremely dense tissue with very little fat. Breast density is very common and it is not a problem in itself (although women that have dense breast tissue have slightly more risk to have breast cancer than women with less dense tissue), but it makes harder to see tumors on mammograms, because they look white, as dense tissue also looks.

Omega-3 fatty acids supplementation, which results in an increase in plasma DHA, has been recently found to reduce breast density in postmenopausal obese women. This is good news.
