Lumps in the armpits can have many origins. Lymph nodes are like filters that can trap microorganisms or cancer tumor cells, when this happens, the lymph nodes increase in size and are easily palpable. Underarm skin cysts and infections can be caused by shaving or the use of antiperspirants, so it is recommended not to use deodorant. This happens most often in the teenage years when young people begin to shave. Subcutaneous abscesses can also produce large, painful lumps in the armpit.

Other causes of armpit lumps can include:

  • AIDS
  • Arm or breast infection
  • Scratch disease Cat
  • Cancers such as lymphoma or breast cancer
  • Chickenpox
  • Infectious mononucleosis
  • Lipomas ( harmless fatty tumors )
  • Normal breast tissue (the breast tissue extends into the armpit area )
  • Use of certain medications or vaccines
  • Shingles ( herpes zoster )


A lump in a woman’s armpit should be examined by a doctor quickly, as it can be a sign of breast cancer .

Home care depends on the reason for the lump, you should always consult your doctor first to determine the cause.

Call your doctor or nurse if you have unexplained lumps in your armpit . Do not try to diagnose lumps (tumors) without professional help.

The physical exam may include gentle pressure on the nodes with the tips of the fingers.

The tests depend on what is found during the physical exam, the doctor may ask questions:

When did you first notice the bump? Is it getting better, worse, or still the same? Are you breastfeeding? Have you noticed any factors that make the problem worse? What other symptoms are also present? Is the lump painful?
