A Cancer Screening operation usually involves a non-invasive or slightly invasive test. Various tests are used for distinctive types of cancers. For instance, mammograms, which use a low-dose X-ray of the breasts, are employed for screening breast cancer. Pap smears, another common test, screens for cervical cancer by using a swab to collect cells from a woman's cervix.
However, some tests are more invasive like colonoscopies for colorectal cancer, which necessitate the insertion of a flexible tube into the rectum to inspect the colon. It's crucial to understand what each procedure involves and engage in a dialogue with your healthcare specialist about potential risks and advantages. Additionally, it's vital to comprehend that screening tests do not confirm the existence of cancer, but only signal a potential issue that necessitates a more specific follow-up diagnostic test.
