About Breast Abscess

Overview

A breast abscess is a painful lump that forms under the skin of the breast. It is typically caused by an infection and is often filled with pus. Breast abscesses can occur as a complication of mastitis, which is an infection of the breast. While they are more common in lactating females, anyone can develop a breast abscess. In non-lactating individuals, obesity and smoking are risk factors for developing abscesses. Symptoms of a breast abscess may include pain, redness, swelling, and warmth in the affected area. It is important to see a doctor for proper diagnosis and treatment of breast infections and abscesses to prevent recurring cases. Treatment may involve antibiotics and drainage of the fluid from the lump.

Causes and Risk Factors

Breast abscess is typically caused by an infection, most commonly due to bacteria entering the breast tissue through a cracked or sore nipple. The infection leads to inflammation and the formation of pus within the breast tissue. Some potential causes of breast abscess include:

• Bacterial infection: The most common cause of breast abscess is a bacterial infection, often caused by Staphylococcus aureus.
• Cracked or sore nipples: Damage to the nipple can provide an entry point for bacteria, increasing the risk of infection.
• Blocked milk ducts: When milk is not properly drained from the breast, it can lead to a buildup of bacteria and subsequent infection.
• Mastitis: An infection in the breast tissue that can progress to an abscess if left untreated.

Non-modifiable risk factors for breast abscess are factors that can’t be changed, including:

• Previous history of breast abscess
• Prior breast surgery
• History of recurrent mastitis

Modifiable risk factors for breast abscess are factors that can be influenced or changed, including:

• Poor breastfeeding technique or inadequate milk removal
• Nipple trauma or damage
• Smoking, which can impair immune function and increase the risk of infection
• Use of certain medications that may suppress immune function

It's important to note that these risk factors may vary from person to person, and it's always best to consult with a healthcare professional for personalized advice.

Symptoms

The most common early symptoms of a breast abscess include:

• Pain
• Redness
• Swelling
• Warm skin
• Nipple drainage
• Discharge from another part of the breast

As the breast abscess progresses or becomes more severe, additional symptoms may occur, such as:

• Fever and chills
• Fatigue
• Low milk production (for breastfeeding individuals)
• Headache
• Nausea and vomiting
• Flu-like symptoms

It's important to note that these symptoms can vary from person to person. If you're experiencing any of these symptoms, it's recommended to see a doctor for an evaluation and appropriate treatment.

Diagnosis

To diagnose a breast abscess, doctors commonly perform the following examinations, tests, and procedures:

• Physical exam: A healthcare professional will assess the lump in the breast and check for signs of infection.
• Health history: Your doctor may ask about your medical history, including any previous abscesses.
• Ultrasound: This imaging test helps visualize the abscess and determine its size, location, and severity.
• Biopsy: In some cases, a biopsy of the tissue and fluid inside the abscess may be taken to confirm the diagnosis and rule out other conditions like cancer or benign cysts.

To determine the stage or severity of a breast abscess, additional examinations, tests, and procedures may include:

• Collecting pus sample: The pus from the abscess may be collected and sent to a lab to identify the specific bacteria causing the infection. This helps guide appropriate treatment.
• Blood tests: These tests can help detect signs of infection and assess your immune health.
• MRI scan: In severe or recurrent cases, an MRI scan may be performed to evaluate the depth of the abscess and its impact on surrounding structures.

It's important to consult with a healthcare professional for an accurate diagnosis and appropriate management.

Treatment Options

The goals of treatment for a breast abscess are to ease symptoms, cure the infection, and prevent recurrence (coming back).

Medications to treat breast abcesses include:

• Antibiotics: Prescribed to clear up the underlying infection. They work by killing or stopping the growth of bacteria.

Therapeutic procedures to treat breast abcesses include:

• Drainage: The pus is drained from the abscess through a small incision or needle aspiration. This helps relieve pain and promote healing.
• Ultrasound-guided aspiration: A minimally invasive procedure where an ultrasound scan is used to guide a needle to remove the pus. This procedure can be used for abscesses small than 3 centimeters (cm).
• Surgical incision and drainage: Reserved for non-resolving abscesses or those with necrotizing signs.
• Percutaneous catheter placement: Used for continuous drainage in unilocular abscesses.
• Vacuum-assisted breast biopsy surgery: Recommended for large or multilocular abscesses.

Health behavior changes for breast abscesses include:

• Applying warm compresses: This can help alleviate pain and promote drainage of the abscess.
• Lifestyle modifications: Discussing your current lifestyle with your doctor can help identify ways to decrease the risk of recurrence.

It's important to note that specific treatment recommendations may vary depending on individual circumstances. Consult with your healthcare provider for personalized advice. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
