What are the benefits of screening?
Screening can detect a problem early, before you have any symptoms. Finding out about a problem early can mean that treatment is more effective. Finding out you have a health problem or an increased chance of a health problem can help people make better informed decisions about their health.
What are the pros and cons of cancer screening?
Improved quality of life is a characteristic feature of good screening. Screenings may also lessen human suffering, for instance. For the society, early-stage cancer treatment saves money. Drawbacks of screenings are both false positive and false negative screening results leading to unnecessary further investigations.
Is screening good or bad?
Researchers began to realize that screening resulted in the frequent diagnosis and treatment of slow-growing cancers that were unlikely to cause harm, as well as false-positive results — when a person is told that they might have cancer when they do not.
What can screening detect?
The primary purpose of screening tests is to detect early disease or risk factors for disease in large numbers of apparently healthy individuals.
Is Cancer Screening Harmful?
Routine cancer screening can save lives. It can also cause serious harm. This is the “double-edged sword” of cancer screening, says Otis Webb Brawley, MD, chief medical officer at the American Cancer Society. “Many of these cancers we treat and cure never needed to be treated and cured,” Brawley says.
When is screening useful?
A screening test is performed as a preventative measure – to detect a potential health problem or disease in someone that doesn’t yet have signs or symptoms. The purpose of screening is early detection; helping to reduce the risk of disease or to detect a condition early enough to treat it most effectively.
Can screening be harmful?
Every screening test can be harmful too. For example, x-ray examinations expose the body to radiation, and endoscopy of the bowel can lead to bleeding or (in rare cases) serious injuries.
What is a disadvantage of screening?
First, there is the added cost of screening tests — to you and to your insurance company. Second, there is the emotional energy that is spent on false-positive results. Eventually, false-positive results will be discovered and the patient informed.
