Breast Lump

Overview

A breast lump is a bump, swelling, or area of firm tissue in the breast that feels different from the rest of the breast. Some lumps are easy to feel with your fingers; others are found on a scan. Many people worry straight away when they find a lump, and that is completely natural. But most breast lumps are not cancer. They can be harmless growths, fluid-filled sacs, or simply the way your breast tissue changes with your monthly cycle.

Yes. Breast lumps are very common. Many people will notice one at some point, and most of the time the cause is harmless. Breast tissue naturally feels lumpy or uneven for lots of people, especially in the days before a period.

Anyone with breast tissue can get a breast lump. It is most common in women, but men can get them too. Lumps can happen in teenagers going through puberty, in women during pregnancy or breastfeeding, and in people after the menopause. The chance of a lump being cancer does rise with age, which is why new lumps are always checked carefully.

Symptoms

Common symptoms

• A bump or firm area in the breast or armpit that you can feel
• A lump that feels different from the rest of the breast tissue
• Skin on the breast looking dimpled, puckered, or like orange peel
• The nipple turning inwards or changing shape
• Fluid leaking from the nipple, especially if it is bloody or comes from one side only
• A change in the size or shape of one breast
• Breast pain or tenderness, which is often linked to harmless causes
• A rash or scaly skin on or around the nipple

Symptoms in children

• Small, tender lumps under the nipple are common in early puberty. These are called breast buds and are a normal part of growing up.
• Breast lumps that are not puberty-related are rare in children.
• A lump in a child that is growing quickly, painful, or one-sided should still be checked by a doctor.

Symptoms in older adults

• New lumps after the menopause should always be checked, because the chance of cancer is higher with age.
• Older adults may notice a lump less easily if breast tissue feels softer or less dense.
• Breast changes such as dimpling or nipple changes are just as important to report at any age.
• Some harmless causes, such as harmless fluid sacs called cysts, are also common in this age group.

Causes

Main causes

• Hormone-related changes in breast tissue, which can make breasts feel lumpy or tender around the monthly cycle
• Fibroadenomas, which are harmless, firm, rubbery growths of breast tissue, common in younger women
• Fluid-filled sacs called cysts, which can appear or change with hormones
• Infections or a build-up of pus (an abscess), often during breastfeeding
• Fat necrosis, a lump that forms after an injury or bruise to the breast
• Harmless growths inside the milk ducts, which can cause nipple discharge
• Swollen lymph nodes in the armpit from infection or other causes
• Breast cancer, which is much less common than the causes above but is the reason every new lump is checked

Risk factors

• Being a woman, since breast cancer is far more common in women
• Getting older, especially over 50
• A close relative (parent, sibling, or child) who has had breast or ovarian cancer
• Inherited gene changes that run in families
• Drinking a lot of alcohol over many years
• Being very overweight, especially after the menopause
• Hormone replacement therapy used for several years
• Starting periods early or reaching the menopause late
• Previous radiotherapy to the chest area

When to see a doctor

See a doctor urgently if:

• You have found a new lump, however small or painless it feels
• A lump has changed in size, shape, or feel
• There is blood-stained discharge from the nipple
• The skin of the breast is dimpled, puckered, or looks like orange peel
• A nipple has turned inwards or the skin around it has changed
• Your breast is red, hot, and swollen, especially with a fever
• You have a lump in the armpit or near the collarbone

Book a routine appointment if:

• You have lumpy, tender breasts that change with your cycle and would like advice
• You want to learn how to check your breasts and what is normal for you
• You have a family history of breast cancer and want to discuss your risk
• You notice a change that has stayed the same for a few weeks and want it looked at

Diagnosis

A doctor will start by asking about the lump and your health history, then examine your breasts and the area under your arms. Depending on your age and what they find, they may refer you to a breast clinic. There, a team usually uses three checks together, sometimes called triple assessment: an examination, a scan, and if needed a small sample of tissue. Using all three together gives the most reliable answer.

Tests that may be done

• Clinical breast examination: the doctor feels both breasts and the armpits carefully
• Ultrasound scan: sound waves create a picture of the lump; often used in younger people or to look at a specific area
• Mammogram: a low-dose X-ray of the breast, usually used from around age 40 upwards
• Fine needle aspiration: a thin needle draws fluid or a few cells from the lump
• Core biopsy: a small sample of tissue is taken with a slightly thicker needle and checked in a lab
• Blood tests or other scans, only if your doctor thinks they are needed

What to expect at your appointment

You may be seen in a one-stop breast clinic where several tests happen in one visit. Scans are quick and usually not painful, though a biopsy can feel like a sharp scratch. Some results are ready the same day, but biopsy results often take about a week. It is normal to feel anxious while waiting. Bringing someone with you, writing down your questions, and asking the staff to explain anything unclear can all help.

Treatment

Treatment depends completely on what the lump turns out to be. Many harmless lumps need no treatment at all and can simply be left alone or checked again in a few months. Others, like a painful cyst or an infection, can be treated simply. If a lump is found to be cancer, a specialist team will explain the options and build a plan with you.

Self-care at home

• Get to know how your breasts normally look and feel, so you notice changes early
• A gentle check in the mirror and in the shower each month is enough; there is no single right way to do it
• Wear a well-fitting, supportive bra if your breasts feel tender
• Try a pain reliever you normally use for period pain, after checking with your pharmacist
• Cut back on caffeine if it seems to make breast tenderness worse for you
• Keep a simple note of any changes and when you noticed them, to share with your doctor

Medical treatments

Treatment is matched to the cause. Harmless fluid sacs can sometimes be drained with a fine needle. Infections need treatment from a doctor, and a pus-filled collection may be drained. Harmless growths may be left alone, watched over time, or removed if they are large or bothersome. If a lump is cancer, treatment is planned by a specialist team and may include surgery, radiotherapy, hormone-based treatment, or other medicines. Your team will explain what is right for your situation and why.

When is surgery considered?

Surgery may be suggested to remove a lump that is large, painful, growing, or found to be cancer. For cancer, surgery is often part of the plan and may be combined with other treatments. Your specialist team will talk you through the type of operation, what to expect afterwards, and how to prepare.

Living with this condition

Between appointments, try to keep your routine as normal as you can. Notice the lump but try not to check it many times a day, as this tends to raise worry without giving new information. Write down questions as they come to you so you can raise them at your next visit.

Lifestyle tips

• Keep active with something you enjoy, like walking, swimming, or dancing
• Limit alcohol and avoid smoking
• Aim for a healthy weight, which lowers breast cancer risk over time
• Get enough sleep and build small moments of rest into your day
• Stay connected with friends and family rather than coping alone
• Keep up with any screening invitations you receive

Diet and exercise

There is no special diet that treats a breast lump. A balanced way of eating with plenty of vegetables, fruit, beans, and whole grains supports your overall health. Regular movement, aiming for about 150 minutes of moderate activity a week, helps with mood, sleep, and weight. If you are going through treatment, your team can advise on any changes you need.

Mental health and emotional wellbeing

Waiting for tests and results can be one of the hardest parts. Feeling scared, tearful, irritable, or numb is very common and completely understandable. These feelings usually settle as answers arrive, but you do not have to sit with them alone. Talking to a friend, your doctor, or a counsellor can make a real difference. If you feel you cannot cope or have thoughts of harming yourself, contact your local crisis support line or your local emergency number straight away.

Prevention

You cannot prevent every breast lump, and some are simply part of normal breast tissue. But you can lower your risk of breast cancer and make sure problems are found early. Being breast aware, attending screening when invited, and living healthily all make a difference.

Vaccines

There is no vaccine for breast lumps or breast cancer.

Screening programmes

In the UK, the NHS breast screening programme invites women aged 50 to 71 for a mammogram every three years; some people are invited earlier if their family history raises their risk. Screening can find changes too small to feel. If you are invited, it is worth going. If you are outside this age range or in another country, ask your doctor what screening is available to you.

Complications

If left untreated

• A breast infection can turn into a painful collection of pus that needs draining
• Some harmless lumps grow larger over time and may need removal
• If a lump is cancer, waiting a long time can allow it to grow or spread, when treatment is usually simpler earlier
• Ongoing worry and anxiety, which can affect sleep, mood, and daily life

Long-term outlook

The outlook for most people with a breast lump is very good, because most lumps are harmless. And when breast cancer is found early, treatment works better and survival rates are high. Finding a lump and getting it checked is a positive step. Whatever the result, there is support and clear next steps available to you.
