What is a lipoma?

Lipoma is a common benign tumor composed of mature fat cells. Its main characteristics are as follows:

1. Symptoms: One or more subcutaneous masses, which are usually small in size (mostly less than 5 cm in diameter), soft and elastic in texture, and generally painless. However, pain or numbness may occur during periods of active growth or if nerves are compressed.

2. Locations: Lipomas can be solitary or multiple, located either subcutaneously or deep within the body. Common sites include the neck, shoulders, back, abdomen, and proximal limbs.

3. Causes: Potential factors may include heredity, chronic inflammation, and systemic abnormalities in fat metabolism.

4. Age of onset: Most commonly seen in middle-aged individuals, particularly those between 40 and 60 years of age.

5. Treatment: Small tumors that do not interfere with normal life can be monitored regularly, while larger tumors or those causing symptoms may be treated by surgical excision.

Lipomas are generally benign. However, if new lumps appear or existing lumps suddenly enlarge, harden, or become painful, prompt medical attention is advised to rule out the possibility of malignancy.
