**Core Concept**
Regular breast examinations are crucial for early detection of breast cancer in high-risk patients. The American Cancer Society recommends annual breast cancer screening with mammography for women aged 45 to 54 years, and biennial screening for women aged 55 years and older. However, for women at increased risk, annual screening may be recommended starting at age 40.

**Why the Correct Answer is Right**
Women at increased risk of breast cancer may include those with a family history of breast cancer, genetic mutations such as BRCA1 or BRCA2, or a personal history of breast cancer. Annual breast examinations help in early detection of breast cancer in these high-risk patients. The American Cancer Society recommends considering risk-based breast cancer screening for women at increased risk.
