The role of a teacher in disseminating information or knowledge cannot be overemphasized. Because of that crucial role they play thus makes it necessary that they have the right information so that they can transfer such to their students or wards. The children today represents the young generation that is growing. It will be good if they have the right knowledge about breast cancer concerning what breast cancer is, what causes it, knowledge of signs and symptoms, and what measures to take to prevent or treat it.

There is low knowledge of risk factors, signs and symptoms, low response to breast self-examination (BSE), clinical breast examination (CBE) and mammography. Educational health programs can be organized to help create more awareness and knowledge about breast cancer which has the potential to help the public in making informed decisions thereby reducing the incidence of this disease.
