What causes enlarged lymph nodes under the armpit and breast?

Understanding Enlarged Lymph Nodes Under the Armpit and Breast
Enlarged lymph nodes, particularly in the armpit (axillary lymph nodes), can be a concerning symptom for many individuals. These nodes play a crucial role in the body’s immune response, filtering lymph fluid and trapping pathogens. When they become swollen, it often indicates an underlying issue that requires attention.
Common Causes of Swelling
Infections are among the most frequent culprits behind enlarged lymph nodes. Localized infections, such as cellulitis or infections in the arm, can lead to swelling in the nearby lymph nodes. This is the body’s way of responding to the infection, as the lymph nodes work to filter out harmful bacteria and viruses. Additionally, systemic infections, like mononucleosis or even the flu, can cause widespread lymph node enlargement, including in the armpit area.
Autoimmune disorders also contribute to lymphadenopathy. Conditions such as lupus or rheumatoid arthritis can trigger an immune response that results in swollen lymph nodes. In these cases, the lymph nodes are reacting to the body’s own tissues being attacked, leading to inflammation and enlargement.
Vaccination reactions can temporarily cause lymph nodes to swell as the body builds immunity. This is a normal response and typically resolves on its own.
Cancer and Lymphadenopathy
One of the more serious causes of enlarged lymph nodes is cancer. Breast cancer, for instance, can lead to swelling in the axillary lymph nodes as cancer cells spread from the breast tissue to the lymphatic system. This is often a critical indicator that requires further investigation, as enlarged nodes in this context may be cancerous themselves.
Moreover, lymphomas, including Hodgkin and non-Hodgkin lymphoma, frequently present with swollen lymph nodes in the armpit. These cancers originate in the lymphatic system and can cause significant enlargement of lymph nodes as the disease progresses.
Other Considerations
In addition to infections and cancer, other factors can lead to swollen lymph nodes. Cysts or abscesses under the skin, often resulting from shaving or irritation, can create painful lumps in the armpit area. Injuries to the arm or hand can also cause localized swelling in the lymph nodes, which is generally non-cancerous.
Conclusion
While enlarged lymph nodes under the armpit and breast can arise from benign causes such as infections or autoimmune responses, they can also signal more serious conditions like cancer. It is essential for individuals experiencing this symptom to consult a healthcare provider for a thorough evaluation and appropriate management. Early detection and treatment can significantly impact outcomes, especially in cases related to malignancies.
