- What Cancer Screening Tests Check for Cancer? - NCI

- Cancer Screening - NCI
Cancer screening is checking for cancer in people who don't have symptoms Screening tests can help doctors find and treat several types of cancer early, but cancer screening can have harms as well as benefits
- Cancer Screening Overview - NCI
Cancer screening trials study new ways of finding cancer in people before they have symptoms Screening trials also study screening tests that may find cancer earlier or are more accurate than existing tests, or that may be easier, safer, or cheaper to use Screening trials are designed to find the possible benefits and possible harms of cancer
- Cancer Screening Overview (PDQ®) - NCI - National Cancer Institute
Commonly used screening tests, such as mammography for breast cancer and prostate-specific antigen (PSA) for prostate cancer, have false-positive rates per screen in the range of 5% to 10%; with repeat screening, cumulative false-positive rates for these tests are substantially higher [2-4] Follow-up invasive diagnostic procedures, such as a
- Detect Cancers Early - National Cancer Plan
The state of early cancer detection today At this time, only a handful of cancer screening tests are known to reduce the chance of dying of a specific cancer and to have benefits that outweigh the harms They are: mammography for breast cancer; HPV and Pap testing for cervical cancer; colonoscopy, sigmoidoscopy, and stool-based tests for
- Cervical Cancer Screening - NCI
The goal of screening for cervical cancer is to find precancerous cervical cell changes, when treatment can prevent cervical cancer from developing Sometimes, cancer is found during cervical screening Cervical cancer found at an early stage is usually easier to treat By the time symptoms appear, cervical cancer may have begun to spread, making treatment more difficult
- Breast Cancer Screening - NCI
Screening is looking for signs of disease, such as breast cancer, before a person has symptoms The goal of screening tests is to find cancer at an early stage when it can be treated and may be cured Sometimes a screening test finds cancer that is very small or very slow growing These cancers are unlikely to cause death or illness during a person's lifetime
- Prevention, Cancer Screening, and Early Diagnosis
Prevention, screening, and other strategies for early detection can reduce the burden of cancer Cancer can be prevented through lifestyle changes that decrease risk and vaccines for cancer-causing infections Cancer screening and early diagnosis of symptomatic disease can identify cancers at early stages when they are more easily treated
