**Core Concept**
Family history of breast cancer, particularly first-degree relatives, is a well-established risk factor for the development of breast cancer. This is due to the potential for inherited genetic mutations in genes such as BRCA1 and BRCA2, which significantly increase the risk of breast cancer.

**Why the Correct Answer is Right**
The presence of a first-degree relative (mother, sister, or daughter) with breast cancer doubles the risk of developing breast cancer. This increased risk is thought to be due to inherited genetic mutations, such as BRCA1 and BRCA2, which are tumor suppressor genes that normally help to repair DNA damage. When these genes are mutated, the risk of breast cancer increases significantly. Additionally, other genetic mutations, such as TP53, PTEN, and CDH1, can also increase the risk of breast cancer.

**Why Each Wrong Option is Incorrect**
**Option A:** Not provided.
**Option B:** Not provided.
**Option C:** Not provided.
**Option D:** Not provided.

**Clinical Pearl / High-Yield Fact**
A family history of breast cancer is a strong predisposing factor, and patients with a first-degree relative with breast cancer should be offered genetic counseling and consideration for genetic testing for BRCA1 and BRCA2 mutations.

**Correct Answer:** D.
