Definition - What does cancer screening mean?
Cancer screening is the testing of the body for cancer indications prior to any cancer symptoms presenting themselves. The purpose of cancer screening is to minimize the occurrences of the disease and fatalities as a result of it. Cancer screening methods vary widely based on the type of cancer being looked for and what part of the body is being examined. Many employers offer cancer screening at health fairs or as part of their employee health insurance plans in an effort to both imrove the health of employees and reduce health care costs.
SureHire explains cancer screening
Cancer screening, testing for cancer and pre-cancerous conditions before symptoms are apparent, is a powerful tool in reducing health care costs and improving health outcomes. The earlier that cancer, or abnormalities that may lead to cancer, can be detected the better the chance of the patient's survival. Once the cancer starts to spread throughout the body and symptoms become apparent, it is often much harder to treat successfully.
Regular screening tests are most effective with cancers of the breast, colon, lungs, and cervix as these cancers respond well to treatment if detected early. Screening methods vary from blood tests to physical exams to x-ray scans.
Screening tests may, however, cause complications where either a false-positive or false-negative result is produced. These results create either unnecessary stress and concern or bring about a false sense of security in the patient. This is why yearly or bi-annual screening for certain cancers is currently recommended.
