Unlike normal cells, malignant or cancerous cells may grow to invade other healthy tissues in the body. Diagnostic tools such as magnetic resonance imaging (MRI), positron emission tomography (PET) scan, and computed tomography (CT) scan may be used as cancer screening tests. A mammogram, pap test, colonoscopy, and prostate-specific antigen (PSA) test may also be used to screen for cancer with the hope of catching the disease in its earliest stages. Diagnostic imaging tests may be used as cancer...

A: Prostate cancer screening refers to testing individuals for prostate cancer to detect the disease in the initial stages. A prostate specific antigen (PSA) test and digital rectal exam are among the procedures that could be used for cancer detection. As per guidelines, yearly prostate screening may be recommended to men more than fifty years of age and men older than forty-five who have risk factors for prostate cancer. If the test results indicate an abnormality, follow-up procedures such as a prostate biopsy or an ultrasound might be advised to make a diagnosis. The incidence of prostate cancer is considered to be...

A: Colon cancer screening is medical testing which is performed to look for the early signs of colon cancer, so that the cancer can be caught quickly if it does emerge. Colorectal cancer is much more treatable if it is caught early, and routine colon cancer screening may be recommended for people who are at an increased risk of developing colon cancer. There are a number of techniques which can be used to assess the health of the colon and to check for early signs of abnormal cell growth. The colonoscopy, a test in which a camera is inserted into the colon so that the doctor can visualize the...

A: Signs of cellular changes that might lead to cervical cancer are detected through cervical cancer screening, which for many women is part of a full pelvic exam. In cervical cancer screening, a sample of cells from the cervix is collected, and these cells are then examined under a microscope for signs of cancer. This test is also known as a Pap test, Pap smear or smear test, and it is a very important part of cervical cancer prevention. In addition to a Pap test, a woman might also undergo a test for the presence of human papillomavirus, the virus that causes most cases of cervical cancer....

A: What happens at a skin cancer screening will vary, depending on your doctor`s approach. When I went for a screening, my doctor basically did a very thorough exam of my entire body. But she didn`t use any special tools. However, I know from talking to other people, that some doctors use a magnifying device to get a better look at your various moles and freckles. There`s an even more involved technique called mole mapping. During a mole mapping session, the entire surface of your skin is documented photographically. By referring to these photos during skin self-exams or office visits, you and your doctors are better able to determine if changes have occurred. The friend who had the mole mapping has a history of...

A: Hi, Skin cancer screening involves 2-3 minute visual inspection or total cutaneous examination involvingscalp, hands and feet. Inclusion of questions regarding sun exposure, sun protection, and family history ofmelanoma in the clinical history, as well as educating at-risk patients on signs, symptoms, and prevention ofskin malignancy, is often included in total cutaneous examination.

A: I think there is a danger here in oversimplifying the results of the cited study. quote - “I am concerned that the complex view of a changing landscape will be distilled by the public into yet another ‘screening does not work’ headline,” Dr. Begg said. “The fact that population screening is no panacea does not mean that it is useless,” he added. ~~ Dr. Colin Begg, biostatistician at Memorial Sloan-Kettering cancer Center in New York - endquote I think that the screening processes are still valid and needed. Early detection will never be a mistake. But what I think may need significant improvement is a better way to tell how aggressive a cancer might be. It seems...
