Dense breasts and cancer screening

There have been recent reports in the news about additional cancer screening for people with dense breasts. This story is a response to a study led by Cambridge University that found that extra scans for some patients could identify early-stage cancers that may not appear during regular mammograms (breast x-rays).

We understand people who see this news story may have questions about what this means. In this blog, we answer some of the most common questions people might have about dense breasts and cancer screening.

If you would like to know more about the study, you can read about it on the Cambridge University website.

How do I know if I have dense breasts?

Dense breasts, also known as dense breast tissue, is when someone’s breast has less fatty tissue. 

Dense breasts are not something you or your doctor can feel or detect with a clinical or self-examination. Only a mammogram can tell if someone has dense breasts. A mammogram is a low-dose x-ray of the breast. It is done by a radiographer and usually offered to people over the age of 40. We have more information about having a mammogram.

Who should I speak to if I have dense breasts?

If you have had a mammogram and been told you have dense breasts, the best person to speak to is your GP. They will be able to help you understand what this means, your breast cancer screening options, and answer any questions you have.

How do I have a screening for breast cancer?

Breast screening is offered to anyone who is registered as female with their GP, and aged between 50 and 70 as part of the NHS Breast Screening Programme. If you are over 70, you can self-refer through your GP.

You will automatically be invited for your first breast screening between the ages of 50 and 53. You will then be invited every 3 years until you turn 71.

The Breast Screening Programme may help find cancer early, which improves someone’s chance of survival. 

We have some general information about cancer screening. There is more detailed information about breast screening and making decisions on the following websites:
