Screening is a process of identifying apparently healthy people who may be at increased risk of a disease or condition. They can then be offered information, further tests and appropriate treatment to reduce their risk and/or any complications arising from the disease or condition.
The benefits of having a screening test include:
- 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.
- Screening can reduce the chance of developing a condition or its complications.
- Some deaths from abdominal aortic aneurysms, bowel cancer, breast cancer and cervical cancer can be prevented.
