Are lumps under armpit contagious

Lumps under the armpit are not contagious, as they are typically caused by non-infectious factors such as swollen lymph nodes, cysts, or infections that are specific to an individual. While some infections, like those caused by bacteria or viruses, can spread, the lump itself is not contagious. If you notice persistent lumps or accompanying symptoms, it's best to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
