Cancer Screening

Cancer screening targets to detect cancer before any symptoms come to surface. This might include blood tests, urine examinations, other assessments or medical imaging. The advantages of screening in terms of cancer prevention, timely detection and succeeding treatment must be pondered against any damage. Screening for cancer can result in cancer avoidance and earlier diagnosis. Early diagnosis might result in higher rates of fruitful treatment and prolonged life.

Breast cancer screening

Breast cancer screening is the medical screening of asymptomatic, outwardly healthy females for breast cancer so as to reach an earlier diagnosis. Numerous screening examinations have been employed, including clinical and self-breast examinations, mammography, genetic screening, ultrasound and magnetic resonance imaging. Breast self-examination (BSE) is a screening technique used to detect initial breast cancer. The technique implicates the woman herself looking at and feeling each breast for potential lumps, distortions or inflammation. Mammography is the procedure of using low-energy X-rays (generally around 30 kVp) to study the human breast, which is used as a diagnostic and screening device. The objective of mammography is the early discovery of breast cancer, normally via finding of characteristic masses and/or micro calcifications. Mammograms use dosages of ionizing radiation to generate images. Radiologists then examine the images for any uncharacteristic discoveries.

Cervical cancer screening

Cervical screening is a method of avoiding cancer by finding and treating initialvicissitudes in the neck of the womb (cervix). These vicissitudes could result in cancer if left untreated. The screening uses a test named cytology, which variousindividuals know as the Pap smear test. A doctor takes a sample of cells from the cervix using small brush. They send the sample to a lab to be tested for any anomalies. In some circumstances, samples are also verified for a virus named human papilloma virus (HPV) that upsurges the possibility of cervical cancer.

Colon cancer screening

Colon cancer screening can discover polyps and early cancers in the intestines. There are numerous ways used for colon cancer screening such as stool test that tests your stool for blood. Two other examinations are named the fecal immunochemical test (FIT) and stool DNA test (sDNA). Sigmoidoscopy is employed that uses a flexible small scope to see the lower portion of your colon. Colonoscopy is done where whole colon can be observed. At times, CT scans are used as a substitute to a regular colonoscopy. Double-contrast barium enema is a special x-ray of the large intestine that gazes at the colon and rectum. Capsule endoscopy encompasses swallowing a petty, pill-sized camera.

Lung cancer screening

The examinations used for lung cancer screening embraces low-dose computed tomography (CT scan, LDCT), chest x-ray, sputum tests, Positron Emission Tomography (or PET scanning, which uses a small quantity of radioactivity to arrange for a comprehensive photograph of an organ’s function). This has been used in blend with CT scanning (PET/CT). It encompasses a higher dosage of radiation than CT alone. Direct visualization of the lungs with bronchoscopy and breathe examination for cancer markers are two other tests that might be employed.
