Bruising occurs when the small, thin blood vessels under the skin break. This is usually the result of bumping the area, which causes small amounts of bleeding.
Developing a yellow bruise on the breast is not usually a cause for concern. It tends to mean that a person has had a blow to the breast.
This article looks at why a yellow bruise might appear on the breast, some treatment options, and whether or not a person should see a doctor.
About 7–10 days after an injury to the breast, a bruise may appear yellow.
Developing a yellow bruise on the breast indicates that an injury or trauma to the breast tissue has occurred, usually about 7–10 days ago.
Not everyone who experiences breast trauma will notice the yellow stage of a bruise. For example, the coloring may not show up in darker skin.

Bumping into an object or sustaining a minor sports injury is enough to cause a bruise. More severe traumas, such as being in a vehicle accident or having a fall, can also cause bruising.
Some people bruise more easily than others. An injury that may cause a bruise in one person may barely leave a mark on another.
Older adults and those with fair skin are more likely to bruise. People who have a condition or use medication that increases the risk of bleeding mean may also bruise easily.
Breast bruising can also occur as a result of domestic or sexual abuse. Anyone who is experiencing such abuse may wish to speak to their doctor confidentially about the options available.
Alternatively, a person can call the National Domestic Violence Hotline on 1-800-799-7233 or TTY 1-800-787-3224. All calls to this number are free of charge.
Breastfeeding can sometimes cause bruising, especially if the infant grabs or squeezes the breast tissue while nursing. Pumping can also occasionally cause bruising around the nipple if the flange, or the part that attaches to the breast, is the incorrect size.
If bruising results from breastfeeding, a person should speak to a lactation specialist, as they may be able to fit a more suitable flange or ensure that the baby’s latch is correct.
Bruising is also common after breast surgery. Some bleeding is likely to occur during esthetic surgery or the removal of a breast lump. Even smaller procedures, such as a breast biopsy, can lead to bruising during the recovery process.
The doctor or surgeon will advise a person on what to expect regarding bruising after surgery.
Some serious conditions can lead to easy bruising, although not specifically on the breast.
- senile purpura, a condition that can affect older adults
- the use of some mediations, such as blood thinners
- von Willebrand’s disease
- easy bruising syndrome, or purpura simplex
- low levels of vitamin C or vitamin K
- vasculitis, or inflammation of the blood vessels
- some gastrointestinal conditions
In this article, learn about more serious conditions that can lead to easy bruising.
Research suggests that a blow to the breast does not increase the risk of developing breast cancer.
Some older studies have suggested that this is possible. However, the American Cancer Society note that although a blow to the breast may result in a lump, it will not increase the risk of breast cancer.
Ordinary bruises are usually easy to manage at home. In the sections below, we look at some home remedies for bruising:

Acetaminophen or ibuprofen can relieve pain and swelling. People with bruises should avoid taking aspirin, however, as it can make bruising worse.
Bruising is not the only skin change that can occur in the breast tissue. Some skin changes are minor, whereas others can signal a more serious condition.
In the sections below, we discuss what other skin changes can affect the breast:
A fungal infection can develop in skin folds under larger breasts. Moisture can collect under the breast and cause redness and itching.

Cellulitis is a bacterial infection of the skin and the underlying tissue. Sometimes, an abscess, or mass, can form. This is a deeper infection.
Anyone with symptoms of cellulitis should see a doctor as soon as possible, as it can worsen over time and lead to further complications.
A doctor will treat cellulitis with antibiotics. If a deeper infection or abscess occurs, a healthcare professional may need to drain it.
Mastitis is an infection of the breast tissue. It commonly occurs during breastfeeding.
Home remedies can often relieve mastitis, but in severe cases, a doctor might prescribe antibiotics.
Anyone who is breastfeeding should ask a doctor before using medications to treat mastitis or any other condition, as they may affect the breastfeeding infant.

Paget’s disease of the breast
In Paget’s disease of the breast, a rash appears on the skin of the nipple and the areola, which is the darker skin around the nipple. It may indicate a rare type of breast cancer.
The symptoms include:
- yellowish or bloody nipple discharge
- flaking or crusting of the skin on or around the nipple
- itching or tingling of the nipple or areola
- a change in the appearance of the nipple
Paget’s disease is rare, and the symptoms often mimic eczema. For these reasons, it can be hard to diagnose.
Inflammatory breast cancer
Inflammatory breast cancer is a rare and aggressive form of breast cancer that causes a blockage of the lymph vessels in the breast. It accounts for
The breast(s) will appear:
In some cases, the skin takes on a pitted appearance that resembles orange peel. This type of cancer does not always cause a solid tumor or lump within the breast.
