When it comes to noticing a lump or swelling under your armpit, it’s important to approach the situation with caution and awareness. While the lump you describe has been present for nearly three years without any noticeable changes or discomfort, it is still advisable to consult a healthcare professional for a thorough evaluation.
Lumps in the armpit area can arise from various causes, including swollen lymph nodes, cysts, lipomas (benign fatty tumors), or even infections. In some cases, they may be related to hormonal changes, especially during pregnancy, as your body undergoes numerous physiological changes. However, it is crucial to differentiate between benign and potentially serious conditions.

1. Swollen Lymph Nodes: The lymph nodes in the armpit can swell due to infections, inflammation, or even systemic conditions. If your body is fighting an infection, the lymph nodes may react by enlarging. This is a common and usually harmless response, but persistent swelling should be evaluated.

2. Cysts and Lipomas: These are typically benign growths. Cysts are fluid-filled sacs that can develop in various parts of the body, while lipomas are soft, fatty lumps that are generally harmless. If the lump is soft, movable, and not painful, it may be a lipoma or cyst.

3. Infections: Sometimes, infections in the skin or deeper tissues can lead to localized swelling. If you notice any redness, warmth, or tenderness in the area, it could indicate an infection that requires treatment.

4. Breast-Related Issues: Given that you are pregnant, hormonal changes can also lead to changes in breast tissue, which may extend to the armpit area. Conditions such as mastitis or other breast-related issues could also manifest as swelling in the armpit.

5. Rare Conditions: While less common, certain conditions, including lymphoma or other malignancies, can present as lumps in the armpit. It’s essential to rule these out, especially if there are other concerning symptoms such as unexplained weight loss, night sweats, or persistent fatigue.

Given that the lump has been stable and you do not feel any hard masses, it may not be an immediate cause for alarm. However, it is always better to err on the side of caution. A healthcare provider can perform a physical examination and may recommend imaging studies, such as an ultrasound, to better understand the nature of the lump. They may also consider blood tests or a biopsy if there are any concerning features.

In summary, while the lump under your armpit may not seem urgent, it is advisable to schedule an appointment with your doctor. They can provide peace of mind by evaluating the lump and determining if any further action is necessary. Regular check-ups and being attentive to changes in your body are key components of maintaining your health, especially during pregnancy.
