Lump of Fatty Tissue on Stomach, Under Skin, Shoulder, Forehead, Neck, Back, Under Armpit.

A fatty tissue growth that develops under skin is known as a lipoma. The growths occur in soft tissues such as in the thighs and abdomen. About 50% of all soft tissue masses are caused by lipoma. Anyone can get these fatty growths. They however rarely occur in children. Although lipomas are classified as tumors, they are largely benign. This means that they won’t spread or invade other body tissues like cancerous tumors do.

Most lipomas are not painful or harmful. Treatment is usually not necessary. If they become bothersome, surgical removal is the best treatment approach.

What causes lipoma lump of fatty tissue under skin

It is not clear what causes lipoma lumps of fatty tissue under skin. Since most people with lipoma tend to have a family history of the condition, some experts associate it with hereditary factors. Lipomas may also appear after an injury. Other risk factors include:

  • Age (between 40-60 years)
  • Madelung’s disease
  • Gardner’s syndrome
  • Adiposis dolorosa

Lipomas may grow more rapidly due to rapid weight gain. Since they do not get metabolized to release energy, losing weight will not have an impact on their sizes.

Symptoms of lipoma fatty tissue under skin

A lipoma lump can go unnoticed for a long time until it forms a lump large enough to be felt or seen. Some lipomas can take years to reach this stage.

Lipomas lumps have the following characteristics:

  • Soft, doughy and rubbery to the touch
  • Located beneath the skin
  • Most measure less than 2 inches in diameter
  • Take the shape of a dome
  • Move readily when pressed with finger
  • Develop slowly
  • Most are painless. However, if a lipoma presses against a nerve or has blood vessels running through it, it can cause pain. You can for example have a painful lump in the breast caused by a lipoma.

Lipomas usually cause a lump in fatty tissue on the shoulder, thighs, abdomen, neck, arms and back. They can however grow in any other soft tissue in the body such as on the breast or on the forehead. A painful lump on the back of leg behind the knee can be caused by lipoma.

Large lipomas or ones occurring deep in fatty tissues require imaging tests. This is common when diagnosing a lipoma lump in fatty tissue on the stomach. Imaging tests are usually performed with MRIs and CT scans. An ultrasound may also be taken.


Treatment is usually not required for a lipoma. If it however tends to keep growing, is painful or bothers you in any other way, you can have it removed. Available treatment options include:

Surgical removal

During liposuction treatment technique, a needle and a large syringe will be used to get rid of the lump. Liposuction may not completely get rid of a lipoma but will greatly reduce its size.

Steroid injections

People with a history of skin cancer or from family lines with a history of cancer are advised to go for treatment immediately after they notice lipoma-like lumps. Although cancerous lumps are in most cases hard and firmly fixed on tissue, some can start in form of soft lumps. The fact that both lipomas and cancerous lumps are not painful makes it a bit hard to differentiate between the two. Also, cancerous lumps rarely cause any symptoms in their early stages. The main difference between the two is that lipomas grow slowly while cancerous lumps grow more rapidly.
