What it means
A lump or mass is an abnormal swelling or growth that can appear anywhere in or on the body. Many lumps are harmless, such as cysts, lipomas, or enlarged lymph nodes from infection. However, a new or changing lump should always be evaluated by a doctor to rule out cancer or other serious conditions. Features that raise concern include rapid growth, hard or fixed consistency, irregular borders, skin changes overlying the lump, or associated symptoms such as pain, fever, or weight loss. Imaging, blood tests, and biopsy may be needed to make a definitive diagnosis and guide appropriate treatment.
