Subcutaneous Lumps: Causes and Concerns - Dermatology

More Info

---

Subcutaneous lumps can arise from a variety of causes, and understanding their nature is crucial for determining whether they pose any health risks. In your case, the lump you described in your left upper abdomen, which has since changed in size and shape, warrants careful consideration.

Firstly, it’s important to note that subcutaneous lumps can be benign or malignant. Common benign causes include lipomas (fatty tumors), cysts, and fibromas, while malignant causes could include sarcomas or metastatic cancer. The fact that you have already undergone a gastroscopy and ultrasound, and that the doctor indicated there was no major concern, is a positive sign. However, the ongoing changes in the lump's size and shape, especially after applying pressure, should be monitored closely.

The lump you mentioned has changed from a size comparable to a soybean to that of a red bean and has taken on an irregular shape, resembling an olive. This change could be due to a variety of factors, including inflammation or a hematoma (a localized collection of blood outside of blood vessels), particularly since you mentioned that you pressed on it forcefully. The redness and change in size could indicate that the body is still responding to the trauma caused by the pressure.

In terms of malignancy, while the characteristics of the lump you described do not immediately suggest a cancerous growth, it is essential to keep in mind that any persistent lump that changes in size, shape, or color should be evaluated further. If the lump does not resolve or continues to change, it would be prudent to seek further evaluation, possibly including imaging studies like an MRI or a biopsy, to rule out any serious conditions.

Additionally, psychological factors can play a role in how we perceive and react to physical symptoms. Anxiety about the lump can lead to increased focus on it, which may exacerbate the sensation of discomfort or lead to further manipulation of the area, potentially causing more inflammation or changes.

In summary, while the initial assessment by your physician was reassuring, the changes in your lump necessitate ongoing observation. If you notice any further changes, such as increased size, pain, or other concerning symptoms, it would be wise to return to your healthcare provider for a follow-up. They may recommend further imaging or a referral to a specialist, such as a dermatologist or an oncologist, for a more thorough evaluation. It’s always better to err on the side of caution when it comes to changes in your body.
