Lipoma examination mainly includes physical examination, imaging examination and pathological examination. Doctors usually touch the place where the growth mass is located. Lipomas are usually soft in texture, with good mobility, no obvious pressure pain, and no skin redness or breakage. Imaging tests, which mainly include ultrasound or CT, can show a localized mass of medium texture with clear boundaries and an encapsulated membrane. Sometimes lipomas are difficult to distinguish from other masses and may even require a percutaneous puncture biopsy or excisional biopsy of the complete mass. If fat particles and connective tissue are found within the tissue, it is often considered a lipoma. After the discovery of a lipoma, patients should go to the hospital for regular follow-up. If the lipoma is found to be rapidly increasing in size or causing significant pain, it is necessary to improve the relevant examinations and perform surgical excision.
