Having a screening mammogram is a personal choice. Understanding the benefits and limitations of screening mammogram can help you decide whether breast screening is right for you.
Benefits
Mammograms can find breast cancer early
- Usually find lumps up to two or three years before they can be felt or symptoms appear.
Early detection may improve treatment options
- Breast cancers found early may be easier to treat and may provide more treatment options.
Regular screening can save lives
- Regular screening with mammography can reduce the risk of dying from cancer.
Peace of mind
- Most people screened do not have breast cancer, and a normal result can be reassuring.
Limitations
Mammograms are not perfect
- Some breast cancers cannot be seen on a mammogram because of the location/type of the cancer or density of the breast tissue.
- The test may not detect cancer even though it is present (called a false negative).
- A normal mammogram does not guarantee that breast cancer is not present.
Breast cancer can develop between screening appointments
- Cancers can develop between mammograms. This is why regular screening is important to allow the radiologist to look for subtle changes between visits.
Additional testing may be needed
- Sometimes mammogram test results suggest you have breast cancer even though you don't (called a false positive).
- Most people who return for additional testing do not have breast cancer. Additional testing may cause temporary discomfort or anxiety.
Mammograms use a small amount of radiation
- Mammograms use a very small amount of radiation.
- For most people, benefits outweigh the risks associated with this low level of exposure.
📌 Note: Even if your mammogram is normal, contact your healthcare provider, if you notice:
- A new lump, mass in your breast or underarm
- Changes in breast size or shape
- Nipple discharge
- Changes to the skin of the breast or nipple
- Persistent, non-cyclical focal breast pain
