Preparing for mammogram

Overview

A mammogram is an X-ray picture of the breast used to look for early signs of breast cancer. It is a routine screening test for women without symptoms or a diagnostic test for those with a breast concern.

Yes, mammograms are a common and routine part of breast health care for women over 50, and for younger women at higher risk.

Mammograms are for people with breast tissue, but screening is primarily recommended for women aged 50 and over. Trans men and non-binary people at similar risk may also be offered screening.

Symptoms

Common symptoms

• A new lump or thickening in the breast or armpit
• Change in size, shape, or appearance of a breast
• Dimpling or puckering of the skin
• Nipple discharge, especially if bloody or clear fluid
• Inverted nipple or change in direction
• Persistent breast pain or discomfort

Symptoms in children

• Mammograms are not performed in children; breast symptoms in children should be evaluated by a doctor with other methods.

Symptoms in older adults

• The same symptoms apply. Older adults may have thinner breasts, making mammograms easier to read, but they are still important.

Causes

Main causes

• The main reason for a mammogram is to screen for breast cancer, not to diagnose a cause. If cancer is found, it’s caused by gene mutations and other factors.

Risk factors

• Getting older (risk increases with age)
• Having a close family history of breast or ovarian cancer
• Certain gene mutations (like BRCA1 or BRCA2)
• Dense breast tissue
• Obesity after menopause
• Alcohol use

When to see a doctor

See a doctor urgently if:

• If you notice any of the symptoms listed above, see your GP within a few days.
• If you have a strong family history, ask your doctor about starting mammograms before 50.

Book a routine appointment if:

• If you are 50 or older and have not had a mammogram, call your local breast screening service to book.
• If you have no symptoms, follow the recommended screening schedule from your national health service.

Diagnosis

A mammogram is an imaging test, not a diagnosis of a condition. If something unusual is seen, further tests like ultrasound or biopsy may be needed.

Tests that may be done

• Screening mammogram – for people without symptoms
• Diagnostic mammogram – if you have a symptom or a previous abnormal result
• Ultrasound – often used after a mammogram for further detail
• Biopsy – taking a small sample of breast tissue for lab testing

What to expect at your appointment

On the day, you will undress from the waist up and stand in front of the machine. A radiographer (technician) will place one breast at a time on a flat plate. Another plate will press down firmly from above for a few seconds to flatten the breast. This may feel uncomfortable or painful, but it helps get a clear picture. You will be asked to hold still and hold your breath briefly. The whole process takes about 20 minutes.

Treatment

A mammogram is a test, not a treatment. If breast cancer is found, treatment options depend on the type and stage. Common treatments include surgery, radiation therapy, and medications (hormone therapy, chemotherapy).

Self-care at home

• Avoid wearing deodorant, lotion, or powder on your breasts or armpits on the day of your mammogram – they can show up on the X-ray.
• Schedule the test when your breasts are least tender (usually a week after your period ends).
• Take over-the-counter pain relievers if your doctor says it’s safe – but do not rely on them regularly.

Medical treatments

If an abnormality is found, your doctor will discuss next steps. These may include a follow-up mammogram, ultrasound, or biopsy. If cancer is confirmed, treatments are tailored to your specific situation and may involve surgery, radiotherapy, or drug therapies. Your healthcare team will explain all options in detail.

When is surgery considered?

Surgery is only considered if a diagnosis of cancer is made. It may involve removing the cancerous tumour (lumpectomy) or the whole breast (mastectomy). Your doctor will only recommend surgery after a full evaluation.

Living with this condition

After a mammogram, you can go back to normal activities straight away. There is no recovery time. You may have some mild bruising or tenderness from the compression, which usually fades within a day or two.

Lifestyle tips

• Do a monthly breast self-exam to know what’s normal for you.
• Keep up with recommended screening appointments (every 3 years if you are 50+ in the UK).
• If you have dense breasts, talk to your doctor about additional screening methods.

Diet and exercise

A balanced diet and regular exercise help lower your overall cancer risk. Aim for at least 150 minutes of moderate activity each week and eat plenty of fruits, vegetables, and whole grains.

Mental health and emotional wellbeing

Waiting for results can be stressful. It’s normal to feel anxious. If you are called back for more tests, remember that most recalls turn out to be nothing serious. Talk to friends, family, or a counsellor if you need support.

Prevention

You cannot prevent breast cancer entirely, but a mammogram is a powerful tool to catch it early when it is easiest to treat. A healthy lifestyle may reduce your risk.

Screening programmes

Regular mammograms are the most effective way to find breast cancer early. In the UK, women aged 50 to 71 are invited automatically. If you are 71 or older, you can still request a mammogram every 3 years.

Complications

If left untreated

• If breast cancer is not found early, it can grow and spread to other parts of the body, making treatment more difficult.
• A mammogram itself has very low risk; the tiny amount of radiation is safe and well below limits.

Long-term outlook

Most breast cancers found by mammogram are caught early, when treatment is very effective. The survival rate for early-stage breast cancer is very high. Even if something is found, modern treatments offer hope and good outcomes.
