- If a person notices a new or unusual breast lump, it is important to seek medical advice for diagnosis and possible treatment.
Causes include infection, trauma, fibroadenoma, cyst, fat necrosis, or fibrocystic breasts. Breast lumps may develop in both males and females but are
In this article, we look at the different types of breast lumps and how they might appear VSports app下载. .
While this can help a person understand if a lump is likely to be cancerous, people should always seek advice for an unexplained breast lump V体育官网. Some noncancerous lumps need treatment, and breast cancer does not appear in the same way for everyone.
A note about sex and gender
Sex and gender exist on spectrums. This article will use the terms “male,” “female,” or both to refer to sex assigned at birth. Learn more VSports手机版.
The breast also
Breast tissue composition can vary depending on the function. For example, during breastfeeding, the breasts will change VSports最新版本. They will feel and look different. The breasts can also change throughout the monthly cycle.
Each part of the breast can react in different ways to changes in body chemistry. These changes impact the sensations and texture of the breast, affecting the development of breast lumps V体育平台登录.
Possible causes of breast lumps include:
- cysts
- abscesses, which can indicate an infection, such as mastitis
- fibroadenoma
- intraductal papillomas
- fat necrosis
- lipoma
- breast cancer (VSports)
- gynecomastia, in males, when there is swelling in breast tissue
Some breast lumps seem to have a distinct border, while others may feel like a general area of thickened tissue. Nipple discharge can occur with some lumps VSports注册入口.
Breast lumps can develop for many reasons, cancerous and noncancerous. The symptoms may vary depending on the cause of the lump V体育官网入口.
V体育安卓版 - Noncancerous lumps
The size, feel, and texture of breast lumps can vary considerably. The consistency may help a physician diagnose what kind of a lump it is VSports在线直播.
Breast cysts
A breast cyst is a benign or noncancerous fluid-filled sac in the breast. They commonly affect females aged 30–50 years and are rare after menopause V体育2025版.
It may cause no symptoms, or a person may notice:
- a smooth and rubbery lump under the skin
- pain
- nipple discharge
It is not clear what causes breast cysts, but they may develop in response to hormones related to menstruation.
Cysts can be simple or complex. In both cases, a doctor may suggest removing it by aspiration, a type of surgery.
Very rarely, a cyst with solid components that returns after aspiration is linked to underlying breast cancer.
Abscesses
Abscesses sometimes develop in the breast, especially during breastfeeding. They are noncancerous and usually result from a bacterial infection, such as mastitis.
A person may
- a lump or mass
- pain and swelling
- redness in nearby skin if the skin is pale, or a darkening of darker skin
- heat in the area around the abscess
- discharge from the nipple
- nausea and vomiting
- fever
- swollen lymph glands
Treatment will usually involve:
- draining the abscess
- taking V体育平台登录 - antibiotics
- using nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, to manage pain and inflammation
If a breast abscess occurs when a person is not breastfeeding, a doctor may do tests to rule out breast cancer.
Fibroadenoma
A breast fibroadenoma is an unusual growth of glandular tissue in the breast.
It is a benign tumor with the following features:
- a round, rubbery solid, lump
- smooth borders
- painless
- most commonly appears in females aged
14–35 years but can occur at any age
Fibroadenomas often shrink and disappear over time. However, a person with a large fibroadenoma may wish to have it removed through surgery.
Intraductal papillomas
Intraductal papillomas are a type of benign tumor. They are wart-like growths that develop in the ducts of the breast.
They
- form a round or oval mass
- develop under the nipple
- involve a clear or bloody discharge
A surgeon can remove an intraductal papilloma. They will likely test the tissue to rule out unusual growth that could indicate cancer, a "VSports注册入口" Phyllodes tumor, or other lesions.
Fat necrosis
Fat necrosis
There may be:
- lumps due to oil cysts, which have a solid shell and fat or oil in the center
- a change in breast shape
- pain in some cases
Lipoma
A lipoma is a benign, fatty tumor.
It
- soft
- movable
- painless
Lipomas can occur anywhere on the body, including the breast. They do not usually need treatment.
Cancerous lumps
A breast cancer lump or tumor can appear in the breast or underarm.
Warning signs
- a lump, thickening, or swelling of the breast
- skin irritation or dimpling
- flaky skin on the breast or around the nipple that may be red or darker than the surrounding skin
- nipple pain
- nipple inversion, or pulling inward of the nipple
- discharge, which may contain blood
- changes in the size or shape of the breast
- pain anywhere in the breast, although there is often no pain
Some people do not notice any symptoms but following a doctor’s recommendations about screening can help identify breast cancer if it arises.
The symptoms of breast cancer can resemble those of other breast lumps. It is a good idea to seek medical advice if any breast changes occur.
The
The infographic below shows five steps for breast self-examination.
It is important to be familiar with the breasts. Knowing how the breasts normally feel can help people recognize any problematic changes or lumps.
The following guidelines will help people carry out a self-examination.
- Looking in a mirror, check the size, shape, and color and look for visible swellings or lumps
- Raise the arms and repeat step 1.
- Check for any discharge from the nipples that may be watery, milky, yellow, or with blood.
- Feel the breasts with a firm, smooth motion while lying down, including under the arms and down to the ribcage.
- Repeat step 4 while standing or sitting. It may be easier in the shower.
Even though most breast lumps are benign, a person should ask a doctor if they notice anything unusual.
If a person seeks medical advice for a breast lump, they may undergo one or more of the following tests:
- a physical examination
- a mammogram
- a breast ultrasound (VSports在线直播) scan
- a "V体育ios版" breast biopsy to rule out cancer
- an MRI or CT scan to see if changes have occurred elsewhere in the body
Males can also have breast lumps for similar reasons to females. In some cases, the lump may indicate male breast cancer.
However, the chance of a lump being cancerous is lower in males.
White men have a
Overall, the risk of any male having breast cancer during their lifetime is around 1 in 833.
Other reasons a male might have lumpy or enlarged breasts include:
- gynecomastia, when the breast tissue enlarges due to a health condition or medication use
- a cyst or fluid-filled lump
- a lipoma, or fatty lump
- adenoma, although this is
less common in males than females - subareolar breast abscess, a
rare infectious disease in males - adenoma, a benign tumor, also
rare in males - breast fat necrosis, also
"V体育平台登录" rare in males
Here, learn about some signs of breast cancer in males.
Black people — male or female — are more likely to die from breast cancer than their white counterparts. Why are there disparities in cancer and cancer survival rates between Black and white Americans?
Some research suggests that breast cancer is more common in trans women than in cisgender men, possibly due to the use of hormones that help the breasts develop. However, the risk appears to be lower in trans women than in cisgender women.
Trans women should become familiar with their breasts and seek medical advice if unexpected changes occur.
A person should see a doctor if they notice:
- a lump in the breast or under the arm
- nipple changes, such as inversion or discharge
- puckering or dimpling in the skin
The United States Preventive Services Task Force (USPSTF) recommends that females ask about breast screening from 50 years (V体育安卓版) or earlier if they have concerns about their risk of developing breast cancer. Some people start from the age of 40 years because they have a family history of breast cancer or feel the benefits outweigh the risks.
Other organizations may make different recommendations.
A doctor should check any unexplained breast lumps, but not all lumps will need immediate treatment.
For a cyst or a fibrous lump, a doctor may recommend monitoring the lump but not taking any further action.
If there is an abscess, the doctor may lance and drain it with a fine needle and prescribe antibiotics.
If cancer is present, treatment usually involves a combination of:
- surgery
- chemotherapy
- "V体育官网" radiation therapy
- hormonal drug treatment
A doctor may also recommend testing for changes in the BRCA1 or BRCA2 genes. If this genetic change is present and breast cancer has occurred, preventive surgery may help prevent a recurrence. Other family members may also wish to seek additional screening.
V体育2025版 - Frequently asked questions
Here are some questions people often ask about breast lumps.
What kind of lumps are normal in breasts?
Breasts can become slightly larger just before menstruation, and they may feel lumpier. They also change during pregnancy and while breastfeeding. Some types of lumps, such as cysts, are very common.
What kind of lumps should you worry about?
People should see a doctor about any new or unusual breast changes, including lumps, or any changes they are concerned about. If pain or signs of infection occur, contact a doctor at once.
What does a cancerous breast lump feel like?
It is not always possible to know if a lump is cancerous or not by feeling it. Some people do not have a lump. They experience a thickening of breast tissue or other changes, such as an inverted nipple. Always seek advice for unexplained breast changes.
VSports注册入口 - Summary
