Probably not: So sorry to hear that. There is a formula that your PCP can go through with you to calculate your risk. Unless your grandmother had an early breast cancer, younger than 40, it probably won't increase your risk of hereditary cancer. 90% of breast cancers are NOT Brca cancers. Typically there is a history of several breast cancers in first degree relatives and early breast cancer.

Yes: Having a second degree relative like a grandmother with breast cancer before the age of 40 is a red flag for possible BRCA. If your grandmother is living then she could be tested. If not, then your mother or father could be tested depending on which side of the family. If they do not have the gene then they cannot pass it on to you. Hope this helps.
