Hi,
Please discuss with your doctor, who could refer you to a good genetic counselor, about this important test considering your family history.
If you have immediate relatives that have been diagnosed with breast or ovarian cancer, you may carry a genetic mutation that increases your risk of those diseases. A little less than 10% of all breast cancers diagnosed in the United States are related to genetic mutations. Some genetic mutations are not inherited, but are somatic, meaning that the genes change during your lifetime and don't get repaired. People who are in these categories do have some choices about preventing and treating breast cancer, but they need to know for sure if they have those genetic mutations.
People with a family history of breast cancer or ovarian cancer may carry the mutated BRCA gene. Men and women who are concerned about their risk of breast cancer may want to visit a genetic counselor to discuss their family health history, as well as other factors, to determine if a genetic test would be helpful.

I am very sorry about the loss of your mom...I wish you a healthy life,but it's always good to be informed on this matter.
Best wishes to both you and your sister...
