There are several factors that put female patients at an increased risk for breast cancer.
According to Amy C. Degnim, MD, professor of surgery, Mayo Clinic, Rochester, MN, “One of the strongest risk factors for breast cancer is a family history of breast cancer, especially if there are multiple family members who have had breast cancer, especially at young ages.”
However, this is not the only factor that physicians should be looking for. In fact, prior benign biopsies can also be indicative of future risk. Several findings, such as atypical hyperplasia or lobular carcinoma in situ, while are not cancerous, can be increase the risk of breast cancer by 1% and 2% respectively.
“As soon as the diagnosis is made, we know that this risk starts, and that risk is fairly continuous over many years. The risk in each year is fairly small, but it adds up over time."
