Is a First Cousin with Breast Cancer Considered Family History?

I have a list of family members with cancer. My brother is going for a biopsy on his prostate tomorrow. I had genetic testing done, and my results were negative for known genetic genes. I hope someone has explained your results to you.

Yes, a first cousin with breast cancer is generally considered part of your family history, though it's categorized as extended family rather than immediate family history. Healthcare providers typically pay closest attention to breast cancer in first-degree relatives like parents, siblings, or children, but second-degree relatives including cousins are still medically relevant information to share with your care team. It's encouraging that your genetic testing came back negative, and this information combined with your family history helps your doctors provide the most appropriate screening recommendations for your situation.
