Medically Reviewed by Carolin Schneider, MD
Most people have experienced lumps in some form, especially if they're older. Most often, lumps are harmless, but, in some cases, they may indicate a dangerous, underlying condition or illness. For example, lumps that form in the armpit area may be formed from extended breast tissue or swollen lymph nodes — and that could be a cause for concern. With this in mind, it's important to watch for changes in size and feel. Moreover, pay attention to how long a lump lasts and if any additional lumps form.
