What is Breast Lymphoma?

Breast lymphoma, also known as primary breast lymphoma (PBL), is a rare type of non-Hodgkin lymphoma that originates in the breast tissue. It is a cancer of the immune system, specifically affecting the white blood cells called lymphocytes.

• Incidence: Breast lymphoma accounts for only 0.5-2% of all breast cancers and 1-3% of all lymphomas.
• Types: There are two main types of breast lymphoma: primary (PBL) and secondary (SBL). PBL is a cancer that originates in the breast, while SBL is a metastasis from another part of the body.

Symptoms

The clinical presentation of breast lymphoma is similar to breast carcinoma. The most common symptoms include:

• A painless, enlarging palpable mass
• Local inflammatory signs such as skin redness and swelling
• Lymphadenopathy (enlarged axillary lymph nodes)

Other symptoms may include night sweats, persistent fevers, unexplained weight loss, and fatigue.

Causes and Risk Factors

The exact cause of breast lymphoma is unknown. However, it is believed to be related to genetic mutations and environmental factors. The risk of developing non-Hodgkin lymphoma increases with age, with most cases occurring in people over 65 years old.

• Age: Non-Hodgkin lymphoma can occur at any age, but the risk increases with age.
• Genetics: Genetic predisposition may play a role in the development of breast lymphoma.
• Environmental factors: Exposure to certain chemicals and radiation may increase the risk of developing breast lymphoma.

Diagnosis

The diagnosis of breast lymphoma is typically made through a combination of:

• Clinical examination
• Imaging studies (e.g., mammography, ultrasound)
• Biopsy and histopathological examination

Treatment

The treatment of breast lymphoma depends on the stage and type of cancer. It may involve surgery, chemotherapy, radiation therapy, or a combination

Breast Lymphoma Signs and Symptoms

Breast lymphoma, a rare form of non-Hodgkin lymphoma, can exhibit similar signs and symptoms to those of breast cancer. The only way to confirm the diagnosis is through a biopsy.

• Painless lump in the breast: This is usually the only symptom, which can be hard to distinguish from a benign tumor or breast cancer.
• Swollen lymph nodes: Lymph nodes in the armpits, neck, or groin may become swollen and painless.
• Chest pain: Pain in the chest area can occur due to the growth of the lymphoma.
• Unexplained weight loss: Some people may experience unexplained weight loss due to the cancer's impact on their metabolism.
• Fever: A persistent fever can be a symptom of breast lymphoma, although it is not specific to this condition.

It's essential to note that these symptoms can also be caused by other conditions, such as infections or benign tumors. Therefore, a proper diagnosis and treatment plan require consultation with a healthcare professional.

Treatment Options for Breast Lymphoma

Breast lymphoma, also known as non-Hodgkin lymphoma (NHL), can be treated with various medications, including chemotherapy and targeted therapy.

• Chemotherapy: This is the most common treatment for NHL. Chemotherapy involves using drugs to kill cancer cells. The standard treatment is anthracycline-based chemotherapy [8].
• Targeted Therapy: Targeted therapy uses specific drugs to target cancer cells. For example, trastuzumab (Herceptin) is used to treat HER2-positive breast cancers [10].

Other Treatment Options

In addition to chemotherapy and targeted therapy, other treatment options may be considered for breast lymphoma.

• Radiation Therapy: Radiation therapy may be used in combination with chemotherapy or as a standalone treatment.
• Surgery: Surgery may be necessary to remove the tumor or affected lymph nodes.

New Developments in Treatment

Researchers are continually exploring new treatments for NHL, including:

• Brentuximab Vedotin: This is a newer drug that has been shown to be effective in treating certain types of NHL [9].
• Zenocutuzumab-Zbco: This is a targeted therapy drug that has been approved for the treatment of NRG1+ pancreatic adenocarcinoma and non-small cell lung cancer.

Important Considerations

It's essential to note that each patient's situation is unique, and treatment plans will vary depending on individual factors such as age, overall health, and specific characteristics of the lymphoma. Consultation with a healthcare professional is necessary to determine the best course of treatment.
