breast X ray explained
Informed by recognized medical guidance
Overview
A breast X-ray, usually called a mammogram, is a safe imaging test that uses a very low dose of radiation to take pictures of the inside of your breasts. It helps doctors see changes in breast tissue that may be too small to feel. The test is often used to screen for breast cancer and to investigate symptoms like a lump or pain.
Key facts
- A breast X-ray is also called a mammogram.
- It uses a small amount of radiation, similar to other standard X-rays.
- During the test, each breast is placed on a flat plate and gently squeezed for a few seconds to get a clear picture.
- It is one of the best ways to find breast cancer early, when treatment is most likely to work.
- The procedure usually takes about 20 minutes and does not need any special preparation.
Yes, breast X-ray (mammography) is a very common test. Many countries offer routine breast screening with mammograms, especially for women aged 50 and over.
It is mostly done for women, particularly those between 50 and 74, as part of regular breast screening. It may also be recommended for younger women and for men who have breast symptoms, though this is less common.
Symptoms
- Call your local emergency number right away if you have severe chest pain, trouble breathing, or signs of a serious allergic reaction (such as swelling of the face or lips) after your breast X-ray. These side effects are extremely rare, but if they happen, get emergency help.
- ⚠See a doctor within a day or two if you find a new, hard lump in your breast that does not go away, or if you see bleeding from the nipple. Also seek urgent care if you have a red, hot, painful breast with a fever, as this could be an infection.
Common symptoms
- A new lump or thickening in your breast or armpit
- Pain in the breast or nipple that does not go away
- A change in breast size or shape
- Nipple discharge, especially if it is clear, bloodstained, or happens without squeezing
- Skin on the breast that is red, dimpled, or puckered
Causes
Main causes
- Many breast changes are benign (not cancer), such as fluid-filled cysts, fibrous tissue, or firm, movable lumps called fibroadenomas.
- Breast cancer is the most serious cause of an abnormal breast X-ray. It happens when breast cells grow out of control.
- Less commonly, an infection called mastitis, an injury, or previous breast surgery can also show changes on a breast X-ray.
Risk factors
- Being aged 50 or older
- Having a close family member (like a mother, sister, or daughter) with breast cancer
- Carrying certain genetic changes, such as in the BRCA1 or BRCA2 genes
- Starting your period early or going through menopause late
- Using hormone replacement therapy (HRT) for a long time
- Being overweight, especially after menopause
When to see a doctor
See a doctor urgently if:
- See a doctor within a day or two if you notice a new lump, bleeding from the nipple, or skin changes like dimpling or puckering.
- If you have a family history of breast cancer and you have not been screened for a long time, book an appointment with your doctor to discuss whether a breast X-ray is appropriate.
Book a routine appointment if:
- If you are in the age group recommended for breast screening in your country, contact your local health service to schedule a routine mammogram.
- If you have any concerns about your breast health, even without symptoms, make a routine appointment with your doctor to get advice.
Diagnosis
A breast X-ray is the main test used to look at breast tissue. It is performed by a specially trained radiographer. During the test, you stand in front of the X-ray machine and one breast at a time is placed on a clear plastic plate. Another plate gently flattens the breast tissue to get a sharp picture. This may feel firm or slightly uncomfortable, but it only lasts a few seconds. A radiologist (a doctor who specialises in imaging) then reads the pictures and sends a report to your doctor.
Tests that may be done
- Mammogram (breast X-ray)
- Breast ultrasound – uses sound waves to look more closely at a specific area, especially if the breast X-ray is unclear
- Biopsy – a procedure to remove a tiny sample of tissue if the doctor needs to check whether a finding is cancer
- Magnetic resonance imaging (MRI) – a more detailed scan sometimes used for women with a high risk of breast cancer
What to expect at your appointment
You may be asked to undress from the waist up and wear a hospital gown. On the day of the test, avoid using deodorant, talcum powder, or lotion under your arms, as these can appear as white spots on the X-ray. The whole appointment usually lasts around 20 minutes. You will get the results from your healthcare team within a few days, and they will explain what they mean and what happens next.
Treatment
Treatment depends on what the breast X-ray finds. If the result is normal, no treatment is needed. If a non-cancerous lump is found, it may simply be monitored or, in some cases, removed. If cancer is detected, a specialist team will plan your care, which may include surgery, radiation therapy, chemotherapy, hormone therapy, or targeted therapies. The exact plan depends on the type, size, and stage of the cancer.
Self-care at home
- Wear a two-piece outfit on the day of your test so you only need to remove your top.
- If your breasts are tender, try to schedule the test for the week after your period, when they are less likely to be sore.
- Ask a friend or family member to go with you if you feel anxious about the test or the result.
- After a breast X-ray, you can return to your normal routine immediately.
Medical treatments
When an abnormal area is found, further tests may be needed to know if it is cancer. If cancer is confirmed, treatment approaches are highly advanced and often combine different methods. Common treatments include surgery to remove the cancer, radiation therapy to destroy remaining cells, and systemic treatments such as chemotherapy, hormone therapy, or targeted medicines. Your cancer team will discuss all options with you and help you choose the best plan for your situation. No specific medicines are mentioned here because the right choice varies for each person.
When is surgery considered?
Surgery is often part of breast cancer treatment. It may involve removing only the tumour and a bit of surrounding tissue (lumpectomy) or removing the whole breast (mastectomy). Surgery may also be offered for some non-cancerous lumps if they cause pain or are large.
Living with this condition
After a breast X-ray, you can go back to your normal activities immediately. If later treatment is needed, you may need to make temporary changes to your routine, especially after surgery or during other treatments. Your care team will guide you on how to manage at every stage.
Lifestyle tips
- Keep a healthy weight for your body.
- Stay physically active – even daily walks can help.
- Limit alcohol to the recommended safe levels.
- Avoid smoking, as it can increase the risk of breast cancer and complicate treatment.
Diet and exercise
Eating a balanced diet with plenty of fruit, vegetables, and whole grains can help you feel better and maintain strength. Regular exercise is also good for mental well-being and can help with recovery. If you are being treated for breast cancer, ask your doctor or nurse about seeing a dietitian or physiotherapist for personalised advice.
Mental health and emotional wellbeing
Waiting for breast X-ray results or hearing about an abnormal finding can feel stressful and scary. These feelings are completely normal. Talking to people you trust, writing down your questions, and seeking support from a counsellor or psychologist can help. Many people find comfort in support groups where others are going through similar experiences.
Prevention
Breast cancer cannot always be prevented, but regular breast X-rays help catch it early, when it is most treatable. Some lifestyle habits may also lower your risk, such as staying physically active, keeping a healthy weight, and limiting alcohol.
Vaccines
There is currently no vaccine to prevent breast cancer.
Screening programmes
Screening mammograms are recommended at regular intervals for many women, but the age and frequency vary by country. For example, in the UK, the NHS offers breast screening every 3 years to women aged 50 to 71. If you are in a screening program, you will receive an invitation automatically. If you have a higher risk due to family history, your doctor may suggest screening at a younger age.
Complications
If left untreated
- If breast cancer is not treated, it can grow and spread to other parts of the body, such as the lymph nodes, bones, liver, or lungs. This can make treatment harder and reduce the chance of a cure.
- Rarely, a non-cancerous lump may grow large enough to cause discomfort or change the shape of the breast, though it is not dangerous.
Long-term outlook
The outlook for breast cancer is improving all the time. Many breast cancers are found early, and when they are, the chance of successful treatment is very high. Even if the cancer is diagnosed later, modern treatments can often control it for many years. Your healthcare team will be with you at every step to help you make the best decisions and live well.
