Should I Be Concerned About a Small Lump on My Arm?

Is it a small tumor?

Hello, about a month ago, I noticed a small lump on the inner side of my arm.
It is not visible from the outside and can only be felt when touched.
However, today I discovered that there seems to be a small lump on the outer side of my arm as well, but it does not hurt when I touch it.
I would like to see a doctor, but I'm not sure which specialty would be best.
Thank you.

Dear user,
You mentioned that you have painless small nodules on the inner side of your arm.
If there are no signs of redness, heat, or other skin abnormalities aside from the lump, it is likely to be a benign subcutaneous tissue tumor.
If these occurrences are frequent or cause you concern, it is advisable to seek assistance from a dermatologist or a general surgeon.
A biopsy may be necessary to confirm the diagnosis.
I hope this information is helpful to you.
Sincerely,
Department of Family Medicine, Keelung Hospital, Chen Bozhang

More Info

When it comes to discovering a small lump on your arm, it’s understandable to feel concerned. While many lumps can be benign and harmless, it’s always wise to have any new or unusual growths evaluated by a healthcare professional.
The first step is to determine the nature of the lump. Lumps can arise from various causes, including cysts, lipomas (fatty tumors), swollen lymph nodes, or even more serious conditions such as tumors. Since you mentioned that the lumps are not painful and are only noticeable upon touch, this could suggest they are benign, but this is not a definitive conclusion.

Given the location of the lumps on your arm, the most appropriate specialist to consult would be a dermatologist. Dermatologists are trained to evaluate skin and soft tissue abnormalities, including lumps and bumps. They can perform a physical examination and may recommend imaging studies, such as an ultrasound, or a biopsy if necessary, to determine the nature of the lump.

If the lumps are found to be related to underlying issues, such as swollen lymph nodes, your dermatologist may refer you to another specialist, such as an oncologist or a general surgeon, depending on the findings. It’s also important to consider your medical history and any other symptoms you may be experiencing, as these can provide valuable context for your healthcare provider.

In the meantime, keep an eye on the lumps. Note any changes in size, shape, or texture, and whether you develop any additional symptoms such as pain, redness, or swelling. These observations can be helpful for your doctor in making a diagnosis.

In summary, while it’s easy to jump to conclusions when you find a lump, the best course of action is to consult a dermatologist who can assess the situation properly. Early evaluation is key to addressing any potential issues, and most lumps are benign and easily treatable. Don’t hesitate to seek medical advice; it’s always better to be safe and informed about your health.

It sounds like it may just be a subcutaneous abscess. I recommend that you first consult a general surgeon. Alternatively, you can keep the area dry and clean, and if it does not increase in size over a period of time, you can simply monitor it.
