Ductal carcinoma in situ DCIS is the most common type of non-invasive breast cancer. It starts in the milk ducts and is non-invasive because it hasn't spread into any surrounding breast tissue. You can find out more on our page on DCIS. Essentially this study found that women who have been diagnosed with DCIS are, on average, 3.

Someone is said to have dense breasts when their mammogram shows they have more glandular and fibrous tissue, and less fatty tissue.

Even though the majority of women exposed to DES won't experience any health issues, research shows that women who took DES while pregnant may have a small increased risk of breast cancer. Research also shows that daughters of women who took DES during pregnancy may have a slightly increased risk of breast cancer after the age of 40 years. If you used DES while you were pregnant, or are a daughter of a woman who took DES, and are 40 years or older you are encouraged to have an annual mammogram.
