Large, abnormal lumps under the skin—especially on the shoulder, back, or arms—could be more than just harmless bumps. Health experts say these swellings may sometimes signal underlying medical conditions that require attention.
While many are benign, such as cysts or lipomas, others could indicate infections, immune disorders, or even cancer. Doctors urge anyone noticing sudden or growing skin lumps to seek professional evaluation.
Your skin could be sending early warning signs—don’t ignore them.
