Cancer screening is looking for cancer before a person has any symptoms. Screening tests can help find cancer at an early stage, before symptoms appear. When abnormal tissue or cancer is found early, it may be easier to treat or cure. By the time symptoms appear, the cancer may have grown and spread. If a screening test result is abnormal, more tests may be done to check for cancer. For example, a screening mammogram may find a lump in the breast. A lump may be cancer or something else. More tests need to be done to find out if the lump is cancer. Hearing screening test, newborn: Screening of the newborn baby's ability to hear. Newborn screening of hearing is done with automated auditory brainstem response tests or, less often, with what are called otoacoustic emission or conventional auditory brainstem response tests. The most common screening tests now include those for hypothyroidism (underactivity of the thyroid gland), PKU (phenylketonuria), galactosemia, and sickle cell disease. The addition of a hearing test to the battery of newborn screening now appears to make medical and economic sense. Screening can be conducted randomly, and substances tested without preselection criteria (which is highly inefficient) or targeted, where information on a substance with known activity and structure is used as a basis for selecting other similar substances on which to run the battery of tests. health screening in the nursing interventions classification, a nursing intervention defined as detecting health risks or problems by means of history, examination, and other procedures.
