a Small Lump on the Left Side: When to See a Doctor

Regarding the small lump in the lower left area?

While showering, I noticed a small round, soft ball located on the lower left side of my body, just below the chest area but on the left side.
It is not protruding and can only be felt more distinctly when pressed at a certain angle.
I can feel it when I press on it, but it doesn't seem to be painful.
I became aware of it while coughing in a side-lying position, and I am wondering if this could be a tumor.
Which medical specialty should I consult if I want to see a doctor? Thank you.

Hello, if the tumor is located subcutaneously, most of them are benign tumors.
You can consult either general surgery or orthopedics.

More Info

When you discover a small lump on the left side of your body, particularly in the area just below the chest, it can understandably cause concern. The first thing to note is that not all lumps are indicative of serious conditions such as tumors. Many lumps can be benign, such as lipomas (fatty tumors), cysts, or swollen lymph nodes. However, it is essential to approach this situation with caution and seek medical advice to rule out any serious issues.

Potential Causes of the Lump
1. Lipoma: A lipoma is a benign tumor made of fat tissue. They are usually soft, movable, and painless. They can occur anywhere in the body, including the area you described.

2. Cyst: A cyst is a sac-like structure that can be filled with fluid, air, or other substances. These can also be painless and may not require treatment unless they become infected or bothersome.

3. Lymphadenopathy: Swollen lymph nodes can occur due to infections or other inflammatory processes. If the lump feels firm and is associated with other symptoms like fever or night sweats, it may warrant further investigation.

4. Muscle Strain or Hernia: Sometimes, what feels like a lump could be related to muscle strain or a hernia, especially if there has been any recent physical activity or strain.

5. Tumors: While less common, tumors can occur in various tissues. If the lump changes in size, becomes painful, or is associated with other symptoms (like weight loss or changes in appetite), it is crucial to seek medical attention.

When to See a Doctor
Given that the lump is not painful and is only noticeable under certain conditions, it may not be an immediate cause for alarm. However, you should consider seeing a doctor if:
- The lump changes in size or shape.

- It becomes painful or tender.

- You experience other symptoms such as fever, unexplained weight loss, or fatigue.

- You have a family history of tumors or cancers.

Which Specialist to Consult
For a lump in the area you described, it would be appropriate to consult a primary care physician first. They can perform a physical examination and may order imaging studies, such as an ultrasound or CT scan, to get a better understanding of the lump. Depending on the findings, they may refer you to a specialist, such as:
- General Surgeon: If the lump requires surgical evaluation or removal.

- Oncologist: If there is a suspicion of a malignant tumor.

- Dermatologist: If the lump is on the skin or subcutaneous tissue.

Conclusion
In summary, while the presence of a small lump can be concerning, many lumps are benign and do not require immediate intervention. However, it is always best to err on the side of caution and consult a healthcare professional for a thorough evaluation. They can provide you with the necessary guidance and treatment options based on their findings. If you notice any changes or additional symptoms, do not hesitate to seek medical attention promptly.
