Why Mammograms Matter: The Importance of Breast Screening in the UK

When it comes to health, early detection is everything. For women across the UK, routine breast screening—commonly known as a mammogram—is one of the most effective ways to spot breast cancer early, when it’s most treatable. It’s quick, safe, and could potentially save your life.

What Is a Mammogram?

A mammogram is a special type of X-ray that captures images of the breast to check for signs of cancer. It can detect changes that are too small to see or feel, often years before symptoms appear. It’s one of the most important tools we have in catching breast cancer early.

The NHS Breast Screening Programme

In the UK, women aged 50 to 71 are invited for breast screening every three years through the NHS Breast Screening Programme. If you’re registered with a GP, you should automatically receive an invitation when you’re due.

Some areas are also part of an age extension trial, inviting women from the age of 47 to 73. If you fall outside this age range but have concerns about your breast health, you can speak to your GP to discuss your options or ask about an early screening based on your individual risk.

Why Early Detection Matters

Breast cancer is the most common type of cancer in the UK. But when found early, it is much more likely to be treated successfully. Screening helps to find cancers at an earlier stage, often before any signs or symptoms appear, giving you more treatment choices and better outcomes.

According to Cancer Research UK, around 1 in 8 women will be diagnosed with breast cancer in their lifetime. But thanks to improvements in screening and treatment, survival rates have significantly improved—more than 8 in 10 women survive breast cancer beyond 10 years.

Common Myths and Concerns

“I feel fine—why do I need a mammogram? Even if you’re healthy and have no symptoms, screening is still essential. Mammograms can detect cancers long before you would notice any changes yourself.

“It’s going to hurt. Mammograms can be a little uncomfortable, as the breast is briefly compressed to get a clear image, but it only lasts a few seconds. Many women find the process easier than they expected.

“I missed my appointment—what now? It’s never too late to rebook. You can contact your local screening unit or your GP surgery to arrange another appointment.

“I’m transgender or non-binary—can I still be screened? Yes. If you have breast tissue and meet the age criteria, you are eligible for screening. You can speak to your GP or the screening service confidentially to ensure your needs are respected.

What to Look Out For Between Screenings

While mammograms are a key part of breast health, it's also important to regularly check your breasts and know what’s normal for you. See your GP if you notice:

• A lump or swelling in the breast, upper chest or armpit

• Changes in the size, shape or feel of your breast

• Skin changes (puckering or dimpling)

• Nipple changes or discharge

• Pain in the breast or armpit

These symptoms don’t always mean cancer, but they should be checked.

Taking Care of Your Health

Breast screening is one of the simplest ways to stay on top of your health. It takes just a few minutes every few years—but those minutes could make all the difference. If you’ve received an invitation, don’t put it off. And if you think you’ve missed one, it’s OK—just reach out and book it in.

Final Thoughts

Your health matters. A mammogram isn’t just a medical appointment—it’s a proactive step towards protecting your future. Encourage your friends, your family, your colleagues to go, too. Talk about it, ask questions, and prioritise yourself. You deserve it.
