Adult women require routine care for the acute and chronic health problems found in both sexes, and they require specialized care for women's health problems, including disease prevention, disease screening, and disease management. Internists should direct primary care and participate in specialized care and to the extent possible follow guidelines published by various professional organizations. They should understand the use of ultrasound in breast cancer screening, the management of pregnancy, and other gynecologic problems, including vaginal bleeding, pelvic pain, and investigation for pelvic malignancy. Finally, all management decisions need discussions on the potential benefit or harm in each step of a woman's care with an emphasis on personal preferences.
