Cancer Screenings: Understanding the Pros and Cons

When it comes to your health, what you don’t know can hurt you. That’s why healthcare providers recommend cancer screenings. These tests look for signs of cancer before you have any symptoms. Cancer screenings can be powerful tools that can help find the disease at an early stage, when it may be easier to treat. Most of the time screenings do not diagnose cancer. Instead, they help your healthcare provider see if you need more tests. For example, a mammogram may find a breast lump, but a lump doesn’t always mean you have breast cancer. You would need a biopsy or another diagnostic test to find out if the lump is cancerous.

What kinds of cancer screenings are available?

When it comes to screening tests, there are many different kinds available. Cancer screening tests can include:

Research studies have shown that some screening tests are accurate, safe, and useful. These screening tools then become standard tests, such as mammograms for breast cancer, Pap smears for cervical cancer, and colonoscopies for colorectal cancer. Your healthcare provider may suggest other screenings for lung, ovarian, prostate, and skin cancer. These tests may be beneficial, especially for people who have an increased risk for that specific cancer type. However, this is not a complete list of all available screenings. It is important to talk with your healthcare provider to decide which ones are recommended for you. Although some tests have not shown to reduce the risk of death from cancer, they may still be able to detect cancer early on.

What are the risks of cancer screenings?

Although cancer screenings have many benefits, you should also be aware of their potential risks:

Understanding the potential risks of any screening test that you’re considering is important. Ask your healthcare provider to help you weigh those risks against the benefits.
