A nurse is educating clients about breast cancer at a community health event. Which of the following statements should the nurse include in the training?
Breast cancer can occur in any part of the breast, but ductal breast cancer is most common.
Breastfeeding increases the risk of breast cancer in women over 40 years of age.
Clients who have BRCA1 or BRCA2 gene changes have a decreased risk of breast cancer.
Clients should begin screening mammography annually by the age of 50 years old.
The Correct Answer is A
Choice A rationale
Breast cancer can occur in any part of the breast, but ductal breast cancer is most common. This statement is correct because the majority of breast cancers originate in the ducts that carry milk to the nipple. Ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) are the most common types of breast cancer, accounting for about 80% of all cases.
Choice B rationale
Breastfeeding increases the risk of breast cancer in women over 40 years of age. This statement is incorrect. In fact, breastfeeding is known to reduce the risk of breast cancer. The longer a woman breastfeeds, the greater the protective effect. This is thought to be due to hormonal changes that occur during lactation, which may delay the return of menstrual periods and reduce a woman’s lifetime exposure to hormones like estrogen that can promote breast cancer cell growth.
Choice C rationale
Clients who have BRCA1 or BRCA2 gene changes have a decreased risk of breast cancer. This statement is incorrect. Mutations in the BRCA1 and BRCA2 genes significantly increase the risk of developing breast cancer. Women with these mutations have a 45-65% chance of developing breast cancer by age 70, compared to about 12% for women in the general population. These genes normally help repair DNA damage, but when they are mutated, they can lead to the development of cancer.
Choice D rationale
Clients should begin screening mammography annually by the age of 50 years old. This statement is partially correct but not entirely accurate. The American Cancer Society recommends that women with an average risk of breast cancer should start annual mammograms at age 45 and can switch to biennial screening at age 55. However, women should have the option to start screening as early as age 40 if they choose.

Explanation
Choice A rationale
Including fluoridated water in the toddler’s diet does not prevent iron deficiency anemia.
Choice B rationale
Administering fat-soluble vitamins daily is not a method of preventing iron deficiency anemia.
Choice C rationale
Limiting intake of high-protein foods is not related to preventing iron deficiency anemia.
Choice D rationale
Avoiding a diet that consists primarily of milk is recommended because excessive milk intake can interfere with iron absorption and lead to iron deficiency anemia.
Correct Answer is B
Explanation
Choice A rationale
8 oz black tea is not recommended for clients with iron deficiency anemia as it contains tannins, which can inhibit iron absorption.
Choice B rationale
1 cup canned black beans is a good source of non-heme iron, which can help improve iron levels and alleviate fatigue associated with iron deficiency anemia.
Choice C rationale
8 oz whole milk is not a good source of iron and can interfere with the absorption of iron from other foods.
Choice D rationale
15 oz raisins contain some iron but are not as rich in iron as black beans. Additionally, the high sugar content in raisins may not be ideal for all clients.
