What kind of doctor provides Cancer Screening?
A primary care doctor, the doctor who handles your everyday health care, is often the first to talk with you about cancer screening. Your doctor or other health care provider talks with you about whether a screening test is right for you. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Cancer screening means checking for cancer, or for abnormal cells that may become cancer, in people who have no symptoms. There are different kinds of screening tests, so the details below stay general. Screening tests include physical exams and health history, lab tests, imaging, and genetic tests. Screening tests usually do not diagnose cancer.
Why a doctor might recommend it
Screening aims to find cancer early, when it may be easier to treat. A good screening test finds cancer early and lowers the chance of dying from it. Expert groups generally recommend these screenings.
- Breast cancer: mammograms, with screening generally starting at age 40.
- Cervical cancer: HPV tests and Pap tests, generally from age 21 to 65.
- Colorectal cancer: colonoscopy, sigmoidoscopy, or stool tests, generally at ages 45 through 75 for people at average risk.
- Lung cancer: low-dose CT scans for some current or former heavy smokers, generally at ages 50 to 80.
People with a higher risk may need screening more often or earlier. Higher risk includes a personal or family history of cancer, certain gene changes, tobacco smoke exposure, and older age.
How to prepare
Talk with your doctor about the benefits and harms of a test before you have it. Ask your doctor whether the test needs preparation and how to do it. Also ask which tests are recommended for you, how often to have them, and when to stop.
What happens during it
Lab tests check samples of tissue, blood, urine, or other substances. Imaging tests make pictures of areas inside the body. Ask your doctor what happens during the test you are offered.
Recovery
Some screening procedures can cause bleeding or other problems. For example, colonoscopy or sigmoidoscopy can cause tears in the lining of the colon. Ask how you will get your results and how long they take.
Risks and side effects
Most screening tests have risks, and not all of them are helpful. A false-positive result looks like cancer when there is none. It can cause worry and usually leads to more tests, which also have risks. A false-negative result looks normal when there is cancer. A person may then delay seeking care even with symptoms. Screening can also find cancers that would never have caused problems, so some people get treatment they did not need. Expert groups generally advise against routine PSA blood tests for prostate cancer in men at average risk because of these harms.
If you notice a lump or other unusual change in the breast, get it checked. Report a new mole or a change to a mole to your doctor promptly.
Who performs it
Your doctor or other health care provider talks with you about the test and orders it if that is your decision.
Common questions
Does a screening test mean I have cancer?
No, a screening test does not mean your doctor thinks you have cancer. Screening tests are done when you have no cancer symptoms.
What happens if a screening result is abnormal?
If a result is abnormal, more tests may be done to check for cancer. These are called diagnostic tests, and they may include a biopsy, where cells or tissue are removed and checked under a microscope.
How does a direct primary care or concierge doctor fit in?
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Before any screening test, your doctor should explain its possible benefits and harms and include you in the decision.
