A new study has found that patients who have early, noninvasive breast cancer and also have dense breast tissue are at a higher risk of the disease recurring compared to those with lower density tissue.
The noninvasive form of the disease, commonly referred to as ductal carcinoma in situ (DCIS), was the central focus of the study, reports MSNBC
. According to the news source, women who had previously been diagnosed with this particular form of the disease in one breast may be three more times likely to develop the condition in the other.
The results were similar to previous studies that examined the correlation between breast tissue density and the risk of developing DCIS. Researchers note that a woman's age is most strongly associated with the risk of developing breast cancer, with density seen as the second greatest factor.
Researchers are now looking for ways to improve how breast density is measured. Currently doctors rely on mammograms, but scientists are working toward developing more advanced instruments.
The American Cancer Society estimates that more than 200,000 women will be diagnosed with breast cancer this year.
