A lumps and bumps biopsy is a simple medical procedure used to evaluate unusual growths, soft tissue swellings, or skin lesions. When a lump is detected under or on the skin, a tiny sample of tissue or fluid is removed for laboratory examination. Doctors typically perform this using fine-needle aspiration, core needle biopsy, or a minor surgical excision under local anesthesia. The harvested sample is then analyzed by a pathologist to determine whether the tissue is benign, inflammatory, or malignant. This essential diagnostic test provides clarity, helping your healthcare team create a safe, targeted treatment plan tailored to your needs.
