Step-by-step explanation:
The correct answer is C. history of Hodgkins lymphoma. Having a history of Hodgkins lymphoma will not result in increased breast cancer risks. Breast cancer risks can be increased by various factors, such as having a mother who took diethylstilbestrol (DES) while pregnant, having a first child before age 30 years, and menarche at an early age (e.g. 10 years). It's important to note that these factors can increase the risk, but they do not guarantee the development of breast cancer.
