It probably is not cancer. But should it be, it is not as aggressive in a woman of her age than it would be in a pre-menopausal woman.
Hi,
Microcalcifications are small calcium deposits found within the breast tissue and these occur normally. However when these calcifications are clustered (grouped) they may increase concern that there may be an underlying abnormality.The BI-RADS score 4a stated on your mom's mammogram and MRI means that the lump is suspicious and to find out the true nature of this lump, a biopsy is the usual procedure.
Most of the time, BI-RADS category 4 abnormalities are benign ,but can be malignant in 25-50% of cases.
Recently, there have been suggestions to categorize the BI-RADS further by adding A, B, and C, to indicated less or more worrisome within the category.A is less suspicious ( like your mom has) and C is more.
Both benign and malignant conditions can occur in women at any age and your mom is not more at risk than a younger woman, especially if there is no family history of breast cancer.
Hoping that all goes well for your mom....Being so far away from her it's certainly very hard,but I am sure that her Breast Specialist will see to it that your mom is well taken care of.
Best wishes to both of you...
