If you feel healthy, a cancer screening probably isn't at the top of your to-do list. That is exactly why screenings exist. A preventive screening is a test that looks for signs of disease before you notice anything wrong. It is part of routine care, like a yearly checkup. You don't need symptoms or a reason to worry to get one.
The value of a screening comes down to timing. When cancer is found early, it is more likely to be in one area and easier to treat. That often means more options and a shorter course of care. Some screenings can even prevent cancer. For example, a colonoscopy can find and remove polyps before they have a chance to turn into cancer.
What to Ask About at Your Age
Every person is different, but here is a general idea of when common cancer screenings begin for people at average risk.
- Cervical cancer screening usually starts at 21.
- Mammograms are recommended starting at 40.
- Colorectal cancer screening begins at 45, which is five years earlier than it used to be.
- Men between 55 and 69 should talk with their provider about prostate screening. Black men or those with a family history may want to start that conversation sooner.
- Adults between 50 and 80 with a history of heavy smoking should check for lung cancer.
What to Ask About at Your History
Your family history can also change these timelines. If a parent, sibling, or child has had cancer, you may need to start screening earlier or be screened more often. For example, if a close relative had colorectal cancer, your provider may recommend starting at 40 instead of 45. The next time you are with family, ask about their health history. It may feel strange, but the answer can shape your care.
People put off screenings for all kinds of reasons. Maybe you feel fine or are worried about the cost, the time, or what the results could show. It may help to know that many insurance plans cover recommended screenings at no cost, and some tests can be done at home. In most cases, results come back normal. If they don't, finding a problem early gives you more treatment options.
Your primary care provider can help you keep track of all of this. They know which screenings you are due for, order your tests, and refer you to a specialist when needed. You do not have to wait for them to bring it up. At your next visit, ask which screenings make sense for your age and history, how often you need them, and what your options are. Bring what you know about your family history and write your questions down ahead of time to make the conversation easier.
Screenings are for people who feel well, so you don't need to wait for a reason to book an appointment. If you do notice a new symptom, contact your provider right away instead of waiting for your next screening. Talk with your provider about which screenings are right for you, and put the next one on your calendar.
