Calciﬁcations are tiny calcium deposits in the breast tissue that can only be seen on a mammogram. These deposits are so tiny that they can’t be felt by you or your doctor during a breast exam.
Breast calcifications can develop in the breast:
Taking calcium pills doesn’t cause breast calcifications.
Yes, there are 2 types of breast calcifications. The type of breast calcification helps a radiologist (a doctor who does imaging tests, like X-rays, ultrasounds, and MRIs) decide if you need more tests.
Microcalciﬁcations are calcium deposits that look like tiny white specks on a mammogram. Microcalciﬁcations usually aren’t related to cancer. But in about 30% of women with microcalcifications, they can be related to an early breast cancer.
Macrocalcifications are calcium deposits that look like single white dots on a mammogram. They are larger than microcalciﬁcations. As women get older they are more likely to have macrocalcifications. Macrocalcifications are found in more than half of all women over 50 years of age and are usually not related to cancer. They may also develop after an injury to the breast.
Your follow-up depends on the type of calcifications and how many calcifications you have.
If you have microcalciﬁcations your follow-up may include:
If you have macrocalcifications, you will have another mammogram. The radiologist will compare your most recent mammograms to ones you’ve had in the past to make sure that the calcifications haven’t changed. As long as the macrocalcifications haven’t changed, you won’t need more testing.
