breast screening test preparation

Overview

Breast screening, also called a mammogram, is an X-ray test that checks your breasts for early signs of cancer. It can find changes in breast tissue before you can feel a lump. The test is quick and usually takes about 20 minutes.

Yes, breast screening is a routine health test offered to women in many countries, especially those aged 50 and over.

Breast screening is primarily for women and people assigned female at birth, usually starting around age 50. Some people with higher risk may be offered screening earlier.

Symptoms

Common symptoms

• Most people have no symptoms at all when they go for breast screening. The test is looking for early changes that cannot be felt.

Symptoms in children

• Breast screening is not part of routine care for children. If a young person has a breast concern, a doctor will assess them individually.

Symptoms in older adults

• Older adults may still be invited for screening if they are in good overall health. Age limits vary; consult your doctor about your personal situation.

Causes

Main causes

• Breast screening is performed to look for breast cancer, which has no single cause. Most cases occur due to a combination of genetic, hormonal, and lifestyle factors.

Risk factors

• Getting older (risk increases with age)
• Having a family history of breast or ovarian cancer
• Having certain inherited gene changes (like BRCA1 or BRCA2)
• Starting menstruation early or menopause late
• Using hormone replacement therapy for a long time
• Being overweight or obese after menopause

When to see a doctor

See a doctor urgently if:

• If you notice a new lump in your breast or armpit
• If your breast looks red, swollen, or sore for no obvious reason
• If you have a change in the size or shape of your breast
• If you have unexplained nipple discharge (especially if it's bloody)

Book a routine appointment if:

• When you receive an invitation for breast screening from your health service.
• If you are between 50 and 70 years old and haven't been screened yet, talk to your doctor about arranging one.

Diagnosis

Breast screening is not a diagnosis; it is a test to look for possible signs of cancer. If the mammogram shows something unusual, you will be called back for more tests (like a second mammogram, ultrasound, or biopsy).

Tests that may be done

• Mammogram: X-ray of each breast, taken while standing. The breast is pressed between two plates for a few seconds.
• Sometimes additional images or an ultrasound may be needed if the first mammogram is unclear.

What to expect at your appointment

On the day of your screening: wear a two-piece outfit (top and skirt/pants). Do not apply deodorant, antiperspirant, powder, or lotion to your chest or underarms, as these can interfere with the X-ray. You will be asked to undress from the waist up. A female radiographer will position you at the machine. The compression may feel uncomfortable but only lasts a few seconds. The whole appointment takes about 20 minutes.

Treatment

If breast screening finds something suspicious, further tests will determine if cancer is present. If cancer is found, treatment will be discussed with your healthcare team. Treatment approaches depend on the type and stage of cancer and may include surgery, radiation, chemotherapy, hormone therapy, or targeted therapies. Your doctor will explain the best options for you.

Self-care at home

• Attend all recommended follow-up appointments after screening.
• If you are called back for more tests, try not to worry — most callbacks turn out to be nothing serious.
• Keep a record of your screening results and any changes in your breasts.

Medical treatments

If cancer is detected, treatment may include surgery (to remove the tumor), radiation therapy (using high-energy rays to kill cancer cells), chemotherapy (drugs that kill cancer cells), hormone therapy (if the cancer is hormone-sensitive), or targeted therapy (drugs that target specific cancer cells). The choice depends on the individual case. Always discuss with your oncologist.

When is surgery considered?

Surgery may be recommended if the tumor is small and localized. Options include lumpectomy (removing the tumor and a small amount of healthy tissue) or mastectomy (removing the whole breast). Your doctor will help you decide based on your situation.

Living with this condition

For most people, breast screening is an occasional event. After a normal result, you continue with your usual routine. If you have been diagnosed with breast cancer, day-to-day life may change during treatment. Seek support from your healthcare team and loved ones.

Lifestyle tips

• Stay physically active — gentle exercise like walking can help manage stress and recovery.
• Limit alcohol intake to reduce breast cancer risk.
• Maintain a healthy weight through balanced diet and activity.

Diet and exercise

There is no special diet needed for breast screening. In general, eating a balanced diet rich in fruits, vegetables, whole grains, and lean protein supports overall health. Regular exercise, such as 30 minutes of moderate activity most days, is recommended.

Mental health and emotional wellbeing

Waiting for screening results can cause anxiety. It is normal to feel worried. If you are called back for more tests, remember that most cases are not cancer. Talk to your doctor or a counselor if you feel overwhelmed. Many people find support groups helpful.

Prevention

You cannot prevent all breast cancers, but screening helps find it early when treatment is most effective. Some lifestyle factors may reduce your risk: staying active, limiting alcohol, maintaining a healthy weight, and breastfeeding if possible.

Complications

If left untreated

• If breast cancer is not detected early, it may grow and spread, making treatment more complex.
• Delayed detection can lead to larger tumors and involvement of lymph nodes or other organs.

Long-term outlook

Breast screening saves lives. The vast majority of women who attend screening have normal results. If cancer is found, it is often caught at an early stage, and survival rates are very high. With modern treatments, most people with breast cancer live long and healthy lives.
