What is nodules or lesions?

Nodules and lesions are both abnormal growths or areas of tissue change in the body. Nodules are typically small, solid masses or bumps that can form in various tissues, often indicating inflammation or a tumor. Lesions refer to any abnormal area of tissue that may be damaged, infected, or diseased, and can vary in size, shape, and type. Both can be benign or malignant and may require medical evaluation for diagnosis and treatment.
