Large, rounded calcifications (macrocalcifications) are common in women over age 50. They look like small white dots on the mammogram. They are most likely not related to cancer. You will rarely need more testing.
Microcalcifications are tiny calcium specks seen on a mammogram. Most of the time, they are not cancer. However, these areas may need to be checked more closely.
WHEN IS FURTHER TESTING NEEDED?
When microcalcifications are present on a mammogram, the doctor (a radiologist) may ask for a larger view so the areas can be examined more closely.
Calcifications that do not appear to be a problem are called benign. No specific follow-up is needed.
In most cases, calcifications that are slightly abnormal but do not look like a problem are also called benign. Most women will need to have a follow-up mammogram in 6 months.
Calcifications that are irregular in size or shape (spiculated), or tightly clustered together, are called "suspicious calcifications." Your health care provider will recommend a stereotactic core biopsy. This is a needle biopsy that uses a type of mammogram machine to help find the calcifications.
Most women who have suspicious calcifications do not have cancer.
