Home Care:

Check with your health care provider to determine the nature of the lump.

For a lump in the armpit caused by an infected, painful gland, follow the instructions about the proper treatment for the underlying infection.

A lump in the armpit caused by a generalized viral infection will eventually disappear without treatment. A lump in the armpit caused by an allergic reaction will go away after the "trigger" is removed. No treatment is necessary for a lump in the armpit caused by normal breast tissue. Usually, no treatment is necessary for a cyst.

A lump in the armpit caused by a lipoma is harmless, unless it grows so large that it causes discomfort.

For a lump in the armpit caused by a malignancy, follow the appropriate cancer treatment recommended by a doctor.

Call your health care provider if:

Call if you have any unexplained armpit lumps. Do not try to diagnose lumps without professional help.

What to expect at your health care provider's office:

Your doctor will perform a physical examination and ask medical history questions about the armpit lump, such as:

When did you first notice the lump?
Is it getting better, worse, or staying the same?
Are you breast-feeding?
Have you noticed any factors that make it worse?
What other symptoms are also present?
Is the lump painful?

The physical examination may include palpation -- gently pressing the nodes with the fingertips.

Testing depends on what is found during the physical examination. Diagnostic tests that may be performed include:

Liver function tests
Kidney function tests
Lymph node biopsy
Platelet count
Routine blood work, such as a complete blood count (CBC)
X-ray of the chest
Liver-spleen scan
Mammogram
