What happens if breast calcifications are malignant? Although breast calcifications are usually noncancerous (benign), certain patterns of calcifications — such as tight clusters with irregular shapes and fine appearance — may indicate breast cancer or precancerous changes to breast tissue.
What kind of breast cancer has calcifications? Sometimes calcifications indicate breast cancer, such as ductal carcinoma in situ (DCIS), but most calcifications result from noncancerous (benign) conditions.
How often is breast calcification cancer? According to one study, suspicious calcifications that require follow-up testing turn out to be cancer approximately 12% to 40% of the time. Other research suggests that many of these cases are likely false positives, where a possible or questioned cancer diagnosis turns out to be benign.
What percent of early breast cancer shows signs of calcification? Sometimes, breast calcifications are the only sign of breast cancer, according to a 2017 study in Breast Cancer Research and Treatment. The study notes that calcifications are the only sign of breast cancer in 12.7 to 41.2 percent of women who undergo further testing after their mammogram.
