What Is a Lipoma?

A lipoma is a benign, non-cancerous growth made up of mature fat cells that forms beneath the skin. Lipomas are enclosed within a thin capsule, which separates them from surrounding tissue. This structure is what makes them behave differently from normal body fat.

Lipomas typically:

• Feel soft and rubbery
• Move easily under the skin when pressed
• Grow slowly over time
• Are usually painless

They most commonly appear on the arms, shoulders, back, neck, or thighs but can develop almost anywhere on the body. 

What Is a Fat Deposit?

A fat deposit refers to normal body fat that accumulates in specific areas due to genetics, hormones, or weight changes. Unlike lipomas, fat deposits are not encapsulated and are part of the body’s natural fat distribution.

Fat deposits typically:

• Feel diffuse rather than well-defined
• Do not move independently under the skin
• Change with weight gain or weight loss
• Are symmetrical across the body

Common areas for fat deposits include the abdomen, hips, thighs, and upper arms.

Key Differences Between Lipomas and Fat Deposits

• Structure

Lipomas are encapsulated growths with clear boundaries, while fat deposits blend into surrounding tissue without a defined edge.

• Movement

A lipoma usually moves when you press on it. Fat deposits feel fixed and spread out rather than mobile.

• Response to Weight Changes

Fat deposits increase or decrease with weight gain or loss. Lipomas remain largely unchanged, even after significant weight loss.

• Location

Lipomas often appear as isolated lumps in areas not typically associated with fat accumulation. Fat deposits tend to occur in predictable patterns.

Why Lipomas Are Often Mistaken for Fat Deposits

Lipomas are frequently mistaken for fat deposits because they are made of fatty tissue and often feel soft. Many people assume a lump is related to weight gain or aging, especially if it develops gradually.

However, because lipomas do not respond to diet or exercise, they tend to persist even when other areas of the body change. This is often when patients seek professional evaluation.

When a Lump Should Be Evaluated

Any new or changing lump should be assessed by a medical professional, especially if it:

• Grows steadily over time
• Feels distinct or well-defined
• Moves independently under the skin
• Causes discomfort or pressure
• Raises uncertainty about what it might be

In some cases, ultrasound imaging may be used to confirm whether a lump is a lipoma or another type of growth.

Can Lipomas Be Treated Like Fat Deposits?

No. Because lipomas are encapsulated, they cannot be reduced through weight loss, exercise, massage, or topical treatments. Fat deposits may change with lifestyle adjustments, but lipomas do not.

The only effective treatment for a lipoma is excision surgery, which removes the growth and its capsule completely. This minor, in-office procedure provides permanent results and prevents recurrence.

Why Excision Surgery Is Recommended for Lipomas

Excision surgery allows for precise removal of the lipoma while preserving surrounding tissue. At Calgary Vein & Laser, this procedure is performed under local anesthesia and typically involves minimal downtime.

Removing the entire capsule is essential, as partial removal can lead to regrowth. Excision surgery ensures both medical clarity and long-term peace of mind.

Making the Right Decision for Your Skin Health

Understanding the difference between a lipoma and a fat deposit can help you decide when professional care is needed. While fat deposits are part of normal body composition, lipomas are distinct growths that require medical assessment.

Calgary Vein & Laser provides expert evaluation to help patients determine whether monitoring or excision surgery is the appropriate next step.
