Although there are clear guidelines that advise at what age to begin screening for various cancers, there is less guidance concerning when it may be appropriate to stop screening. The decision to stop screening must take into account patients' age; overall health and life expectancy; the natural history of the disease; and the risks, expense, and convenience of the screening test, and any subsequent testing and treatment. The U.S. Preventive Services Task Force and the American Academy of Family Physicians suggest that Papanicolaou smears can be discontinued in women at 65 years of age, provided they have had adequate recent normal screenings. Evidence suggests that cessation of breast cancer screening at approximately 75 to 80 years of age is appropriate, although American Geriatric Society guidelines recommend cessation at a more advanced age. Studies support continuing colon cancer screening until approximately 75 years of age in men and 80 years of age in women for patients without significant comorbidities. Prostate cancer screening, if conducted at all, may be discontinued at approximately 75 years of age in otherwise healthy men. Ultimately, the decision to screen or to discontinue screening must be made after careful discussion with each patient, using evidence-based guidelines and individual patient preferences. |
