In the United States, annual deaths from breast cancer and cervical cancer outnumber deaths caused by all other types of gynecological cancer. Although early detection and intensive treatment can save the lives of a great number of victims, many Americans often fail to follow recommended detection procedures. The nurse practitioner's global approach and advanced level of knowledge allow her to intervene at all stages of care delivery, and consequently give her a key role in preventing these ailments. She is able to evaluate a client's state of health and the quality of health care offered to the clientele. She can explain to women the risk factors for cancer, design programs for early detection and intervention, and follow up on clients' treatments. By pointing out health care needs to the members of the care team, the nurse practitioner works toward improving care quality. She is called upon to defend women's interests in discussions likely to have an impact on the detection and treatment of breast cancer and cervical cancer.
