A breast biopsy is not a screening test. A screening test is a test used to detect disease in a patient who has no signs and symptoms. A breast biopsy is a test used to detect disease in someone who has signs and symptoms.

The purpose of screening mammography is breast cancer detection. A screening test, by definition, is used for patients without any signs or symptoms, in order to detect disease as early as possible.
Colonoscopy is being used increasingly as a screening tool in both asymptomatic patients and patients at risk for colon cancer. It has been recommended as a screening test in all people 50 years or older.
Breast Cancer clinical trials are used to test new medicines, procedures, and surgeries to better aid in the treatment and finding a cure for the cancer.
The Papanicolou test is used to detect possible precancerous and cancerous lesions that need further evaluation. It is not a diagnostic test, but is a screening test. Most commonly, we think of pap smears as detecting cervical cancer, but they may also be used to detect vaginal or anal cancer.
Currently, there is no reliable screening blood test for ovarian cancer that is recommended for the general population. The most commonly discussed test is the CA-125 blood test, which measures the level of a protein that may be elevated in women with ovarian cancer, but it is not specific enough to be used for screening. This test can lead to false positives and unnecessary procedures in women without cancer. Regular pelvic exams and awareness of symptoms are important for early detection, especially for women at high risk.
Screening refers to tests and exams used to find a disease, like cancer, in people who do not have any symptoms. The goal of screening exams, such as mammograms, is to find cancers before they start to cause symptoms. Breast cancers that are found because they can be felt tend to be larger and are more likely to have already spread beyond the breast. In contrast, breast cancers found during screening exams are more likely to be small and still confined to the breast. The size of a breast cancer and how far it has spread are important factors in predicting the prognosis (outlook) for a woman with this disease.
The purpose of screening mammography is breast cancer detection.
The PSA test, is a test to check the prostate-specific antigen. This test is used as an early screening test to detect prostate cancer in men. All men over the age of 50 years old should have a PSA screening test yearly.
Colonoscopy is being used increasingly as a screening tool in both asymptomatic patients and patients at risk for colon cancer. It has been recommended as a screening test in all people 50 years or older.
It is a screening test of a woman's uterus to look for pre-cancerous and cancerous cells. If you have them done regularly, any changes can be looked out for and checked out. During a pap smear, a tool is used to take cells from the outer opening of the cervix, the uterus and endocervix. The cells are examined under a microscope to look for abnormalities.

The initial screening test for cervical cancer is the Pap smear. This test is not specific, however; the more specific test used when the smear indicates the need for further treatment is the cervical biopsy.
