Breast lump
A breast lump is swelling, growth, or mass in the breast.
Breast lumps in both men and women raise concern for breast cancer, even though most lumps are not cancer.
Breast cancer
Breast cancer is cancer that starts in the tissues of the breast. There are two main types of breast cancer:Ductal carcinoma starts in the tubes (du...

Both males and females of all ages have normal breast tissue. This tissue responds to hormone changes. Because of this, lumps can come and go.
Breast lumps may appear at any age:
- Both male and female infants may have breast lumps from their mother's estrogen when they are born. The lump will most often go away on its own as the estrogen clears from the baby's body.
- Young girls often develop "breast buds," which appear just before the beginning of puberty. These bumps may be tender. They are common around age 9, but may happen as early as age 6.
- Teenage boys may develop breast enlargement and lumps because of hormone changes in mid-puberty. Although this may be upsetting to boys, the lumps or growth almost always go away on their own over a period of months.
Causes
Lumps in a woman are most often either fibroadenomas or cysts, or just normal variations in breast tissue known as fibrocystic changes.
Fibrocystic changes are painful, lumpy breasts. This is a benign condition that does not increase your risk for breast cancer. Symptoms are most often worse right before your menstrual period, and then improve after your period starts.

Fibroadenomas
Fibroadenoma of the breast is a benign tumor. Benign tumor means it is not a cancer.
Read Article Now Book Mark Article- They move easily inside the breast tissue and are usually not tender. They occur most often during the reproductive years.
- These lumps do not have cancer or become cancerous except in rare cases.
- A health care provider may sometimes suspect a lump is a fibroadenoma based on an exam. Also, an ultrasound and a mammogram can often provide information to determine if a lump looks like a fibroadenoma.
- The only way to be sure, however, is to have a needle biopsy or remove the whole lump.
Fibroadenoma
A fibroadenoma is a non-cancerous benign lump that is found in breast tissue. When felt under the skin, the lump may feel rubbery and easily moveable within the breast tissue. Fibroadenomas are commonly found in young women during their reproductive years.
Cysts are fluid-filled sacs that often feel like soft grapes. These can sometimes be tender, often just before your menstrual period. Ultrasound can determine if a lump is a cyst. It can also reveal whether it is a simple, complicated, or complex cyst.
Cysts
A cyst is a closed pocket or pouch of tissue. It can be filled with air, fluid, pus, or other material.
Read Article Now Book Mark Article- Simple cysts are just sacs filled with fluid. They do not need to be removed and may go away on their own. If a simple cyst is growing or causing pain, it can be aspirated.
- A complicated cyst has a little bit of debris in the fluid and can either be watched with ultrasound or the fluid can be drained.
- A complex cyst looks more worrisome on ultrasound. Your provider may recommend either a follow up ultrasound or a needle biopsy. Depending on the results, the cyst may be monitored with ultrasound exams or removed surgically.
Fibrocystic breast change
Fibrocystic breast change is a common and benign change within the breast characterized by a dense irregular and bumpy consistency in the breast tissue. Mammography or biopsy may be needed to rule out other disorders.
Other causes of breast lumps include:
- Breast cancer.
- Injury. Blood may collect and feel like a lump called a hematoma if your breast gets badly bruised. These lumps tend to get better on their own in a few days or weeks. If they do not improve, your provider may have to drain the blood.
- Lipoma. This is a collection of fatty tissue.
- Milk cysts (sacs filled with milk). These cysts can occur with breastfeeding.
- Breast abscess. These typically occur if you are breastfeeding or have recently given birth, but can also occur in women who are not breastfeeding.
Abscess
An abscess is a collection of pus in any part of the body. In most cases, the area around an abscess is swollen and inflamed.

Home Care
See your provider if you have any new lumps or breast changes. Ask about your risk factors for breast cancer, and screening and prevention for breast cancer.
When to Contact a Medical Professional
Contact your provider if:
- The skin on your breast appears dimpled or wrinkled (like the peel of an orange).
- You find a new breast lump during self-exam.
- You have bruising on your breast but did not experience any injury.
- You have nipple discharge, especially if it is bloody, clear like water, or pinkish (blood-tinged).
- Your nipple is inverted (turned inward) but normally is not inverted.
Also make contact if:
- You are a woman, age 20 or older, and want guidance on how to perform a breast self-exam.
- You are a woman age 40 or older and have not had a mammogram in the past year for advice about screening for breast cancer.
What to Expect at Your Office Visit
Your provider will get a complete history from you. You will be asked about your factors that may increase your risk for breast cancer. Your provider will perform a thorough breast exam. If you don't know how to perform a breast self-exam, and want to do this, ask your provider to teach you the proper method.
Breast self-exam - Animation
If you're a woman, your doctor or gynecologist may have recommended that you examine your breasts every month to check for lumps. You might be wondering, why do I need to do a breast self-exam? Or, you might ask, how do I examine my breasts, and what exactly am I looking for? Well, let's talk about why, and how to examine your breasts. Why examine your breasts? Well, for one thing, it helps you get an idea of how they normally feel. Then if there's ever a problem, you'll be familiar enough with your breasts to spot it. For example, a lump on your breast could be a sign of breast cancer. Finding that lump could allow you to get checked out with a mammogram earlier than you might have done if you didn't do breast self exams. But, this is a two edged sword. Many expert groups no longer recommend routine breast self examination because the consequences of over treatment of benign or normal lumps may outweigh the benefits of early detection. Lumps lead to extra mammograms, which often lead to biopsies, and the biopsies turn out to be benign, or normal, in more than 90% of cases. But, not always. Some expert groups simply recommend breast self awareness. Ultimately, the choice is yours. If you are going to do breast self exam, the best day to do a self exam is about 3 to 5 days after your period ends. Your breasts are naturally less lumpy right after your period, so there's less of a chance that you'll mistake a normal bump for an abnormal growth. If you've already gone through menopause and your periods have stopped, just do your exam on the same day every month. Mark it on your calendar so you won't forget. To do the exam, lie on your back, as it's easier to feel any lumps or changes when you're lying down. First, put your right hand behind your head. Then, using the middle fingers on your left hand, gently but firmly press down, circling your entire breast. Make sure you cover the whole right breast. Squeeze your nipple gently. See if any fluid comes out. Now, sit up, and feel around your armpit. When you're done with the right breast, repeat the whole check on the left side. Next, stand in front of a mirror. With your arms down at your sides, look at both breasts. Check the shape of each breast. Look for any changes in the skin, like dimpling or puckering. Also see if your nipples now turn inward. Now, do the exact same check again with your arms over your head. After you've done a few breast self-exams, you'll become familiar with the look and shape of your breasts. At each exam, you're looking for anything different, like new bumps, changes in the texture of your skin, or discharge from your nipple. If you do notice that something has changed, don't panic, it could mean many different things. But, call your doctor as soon as you can so you can find out what's caused the change, and, if necessary, get it treated.
You may be asked medical history questions such as:
- When and how did you first notice the lump?
- Do you have other symptoms such as pain, nipple discharge, or fever?
Nipple discharge
Nipple discharge is any fluid that comes out of the nipple area in your breast.

How a breast lump is treated depends on the cause.
- Solid breast lumps are usually biopsied with a needle by the radiologist. Depending upon the situation, they might be removed with surgery. They can also be monitored over time by your provider.
- Cysts can be drained in your provider's office. If the lump disappears after it is drained, you do not need further treatment. If the lump does not disappear or comes back, you might need to be rechecked with exam and imaging.
- Breast infections are treated with antibiotics. Sometimes a breast abscess needs to be drained with a needle or surgically drained.
- If you are diagnosed with breast cancer, you will discuss your options carefully and thoroughly with your provider.
