Bacterial infections or abscesses can create swollen, painful lumps, often with redness or warmth. These usually need medical treatment.

4. Some Lumps May Be More Serious

Though rare, lumps on the hands can be caused by:

Tumors (benign or malignant)

Rheumatoid nodules – linked to autoimmune disorders

Bone or soft tissue cancers – uncommon but possible

5. When to See a Doctor

You should seek medical advice if a lump:

Grows rapidly

Is painful or tender

Limits hand or finger movement

Changes color or bleeds

Persists for several weeks

6. Diagnosis May Require Imaging or Biopsy

Doctors may use ultrasound, MRI, or even a biopsy to determine the nature of the lump.

Bottom line:

While most hand lumps are harmless, it’s important not to ignore changes. Getting a lump evaluated early can rule out serious conditions and ensure proper treatment if needed.
