For the prevention of lipomas, it is first necessary for patients to strictly control their weight. This is because if there is an excess of fat in the body, it is very easy for lipomas to form. Therefore, it is recommended that patients maintain a light diet in everyday life, avoiding the intake of too much high-fat and high-cholesterol food. They should eat more fresh vegetables and fruits, maintain a pleasant mood, relieve worries, avoid emotional tension, and regularly participate in exercise.

Do lipomas require hospitalization?

Lipomas belong to superficial tumors and are categorized as benign. They are caused by the proliferation of subcutaneous adipose tissue. If treatment is desired, surgery is an option. Medication or other treatments are ineffective. If the lipoma is small, it can be surgically removed in an outpatient setting, typically under local anesthesia. For a larger lipoma, it is recommended that the patient be hospitalized for surgery, which involves intravenous anesthesia combined with local anesthesia to remove the lipoma.

Lipoma CT presentation

Lipomas are relatively common clinically and are one of the more frequent types of superficial tumors, commonly occurring on the limbs and trunk. Generally, a physical examination and ultrasound are sufficient for an accurate diagnosis of a lipoma, and there is no need for the patient to undergo a CT scan. However, if a CT scan is performed, lipomas can present in the following ways: first, a regular or lobulated mass may be found under the skin with sparse blood flow and a regular shape; second, on a CT scan, lipomas appear as low-density lesions, with CT values typically ranging between -70 HU to -90 HU. Diagnosis of a lipoma can be confirmed through these two observations.

Do lipomas infect other people?

Lipomas are non-contagious and are tumorous formations of normal fatty tissue, often found in the limbs and trunk. They generally have clear boundaries, are soft in texture, and may feel cystic without causing pain. Lipomas grow slowly and can sometimes become very large. For most lipomas, observation is sufficient, and diagnosis can be confirmed through ultrasonography. Most patients do not require surgical treatment. However, if there is suspicion of malignancy in deeper lipomas, timely surgical removal is necessary. For lipomas that grow rapidly, cause symptoms, or affect appearance, early surgical intervention is also recommended. If pathology confirms the diagnosis, some lipomas may be liposarcomas. Most can be assessed for risk, and further treatment might be needed.

Do lipomas hurt?

Lipomas are very common in clinical practice, often found on the limbs and trunk. They are relatively superficial tumors located under the skin, composed of fatty tissue. Most patients do not exhibit obvious clinical symptoms and only discover a mass under the skin. The mass typically appears lobulated or flat, is fairly firm, and does not present any redness on the surface. It can be moved, which is a characteristic manifestation of lipomas. However, a very small number of patients may experience pain in the lipoma, at which point surgery can be considered to alleviate the pain.

Are lipomas contagious?

Lipomas are surface tumors caused by the proliferation of subcutaneous tissues. They are benign tumors, not bacterial infections or contagious diseases. Therefore, lipomas are not contagious. Patients with lipomas can normally interact with other people without causing the spread of lipomas among the population, which is nothing to worry about. After the occurrence of a lipoma, it can be surgically removed. Generally, a lipoma can be completely excised under local anesthesia, and after the wound is sutured, the lipoma is cured.
