Cancer screenings are preventive healthcare measures that involve testing for cancer in individuals without current symptoms. The process varies depending on the type of cancer being screened. Here's a general overview of how some common cancer screenings are done: 1. Breast Cancer Screening: Typically involves a mammogram, which is an X-ray of the breast tissue. It can help detect tumors at an early stage. 2. Cervical Cancer Screening: Often done through a Pap test (Pap smear) and/or an HPV (Human Papillomavirus) test. The Pap test examines cells from the cervix for signs of cancer or precancerous conditions. 3. Colorectal Cancer Screening: Can include a fecal occult blood test (FOBT) which detects hidden blood in the stool, or more invasive tests like a colonoscopy, where a doctor uses a colonoscope to examine the inside of the colon and rectum. 4. Lung Cancer Screening: For high-risk individuals, this may involve a low-dose CT (computed tomography) scan of the chest to detect lung nodules or abnormalities. 5. Prostate Cancer Screening: Often involves a blood test for prostate-specific antigen (PSA) levels and/or a digital rectal exam (DRE) where a doctor examines the prostate gland for any hard lumps or abnormalities. It's important to note that while cancer screenings can detect cancer early, they are not a substitute for a thorough medical examination or treatment. Individuals should discuss with their healthcare provider which screenings are appropriate for their age, gender, and risk factors. read more >>

Getting screening tests regularly may find breast, cervical, and colorectal (colon) cancers early, when treatment is likely to work best. Lung cancer screening is recommended for some people who are at high risk.read more >>
