When Should a Lipoma Be Removed?

A soft lump under the skin can be concerning, especially when it appears to grow over time. One common cause is a lipoma, a benign growth made up of fat cells. Lipomas are generally harmless, but that does not mean they should always be ignored.

For patients wondering when a should a lipoma be removed, the answer depends on several factors, including its size, location, growth pattern, symptoms, and whether the diagnosis is certain. Understanding these factors can help patients make informed decisions about evaluation and treatment.

What Is a Lipoma?

A lipoma is a noncancerous growth of fatty tissue that develops between the skin and the underlying muscle. Lipomas are typically soft or rubbery and may move slightly when touched. They can occur almost anywhere on the body but are commonly found on the shoulders, arms, back, thighs, and torso.

Most lipomas grow slowly and do not cause pain. Some remain small, while others can gradually become larger over many years.

Although lipomas are usually benign, a new or changing lump should still be evaluated by a qualified medical professional. Not every lump under the skin is a lipoma, and an examination may be necessary to determine what is causing it.

When Should a Lipoma Be Evaluated?

A lipoma should be evaluated if it is new, changing, painful, or causing concern. Evaluation is particularly important when a lump grows quickly, feels unusually firm, is fixed to surrounding tissue, or appears deeper beneath the skin.

A physician may be able to identify a typical lipoma through a physical examination. Depending on the characteristics of the mass, imaging such as an ultrasound or MRI may sometimes be recommended.

The goal of evaluation is not only to determine whether the growth is a lipoma but also to make sure another type of soft-tissue mass is not being overlooked.

When Should a Lipoma Be Removed?

A lipoma does not necessarily need to be removed simply because it exists. However, removal may be appropriate when the growth causes symptoms, interferes with daily activities, continues to enlarge, or creates significant cosmetic concerns.

Pain is one reason patients may consider removal. While most lipomas are painless, a larger lipoma can sometimes press on nearby nerves or other tissues and contribute to discomfort.

Location can also matter. A lipoma near a joint, for example, may interfere with movement depending on its size and position. A growth in an area exposed to pressure from clothing or physical activity may also become irritating.

Some patients choose removal because of the appearance of the lump. Even when a lipoma is medically harmless, a visible or prominent growth can affect how a person feels about their appearance.

Does a Growing Lipoma Need to Be Removed?

Growth does not automatically mean that a lipoma needs to be removed, but a growing lump should be evaluated.

Typical lipomas generally enlarge slowly. A mass that is increasing in size, particularly if the growth seems rapid or is accompanied by pain or other changes, deserves medical attention.

The important distinction is between deciding whether a known lipoma is bothersome enough to remove and determining whether a growing mass is actually a lipoma. A physician can help make that distinction through an examination and, when appropriate, diagnostic testing.

How Are Lipomas Removed?

The most common treatment for a symptomatic or bothersome lipoma is surgical removal. During the procedure, the physician removes the fatty mass through an incision in the skin.

The approach depends on the lipoma’s size, depth, and location. Smaller, superficial lipomas may be relatively straightforward to remove, while larger or deeper growths may require more careful planning.

Once removed, the tissue may be sent to a laboratory for examination. Pathology can help confirm the diagnosis and provide additional information about the tissue.

Can a Lipoma Come Back After Removal?

A lipoma that has been completely removed typically does not return in the same location. However, some people develop additional lipomas elsewhere on the body.

For this reason, discovering another lump after a previous lipoma removal does not necessarily mean the original growth has returned. A new lump should still be evaluated to determine what it is.

What Should You Do About a New Lump?

A new lump under the skin should not automatically be assumed to be a lipoma. While lipomas are common and usually harmless, other types of masses can look similar.

Patients should pay attention to changes in size, shape, firmness, mobility, and symptoms. A lump that grows quickly, becomes painful, feels firm or fixed, or is located deeper in the body should receive prompt medical evaluation.

The most appropriate next step is a clinical examination. Depending on the findings, a physician may recommend observation, imaging, biopsy, or removal.

Is Lipoma Removal Always Necessary?

No. Many lipomas can safely be monitored when they are small, stable, painless, and have characteristics consistent with a benign lipoma.

Removal becomes more reasonable when a lipoma is painful, growing, restricting movement, repeatedly irritated, cosmetically bothersome, or difficult to distinguish from another type of mass.

Ultimately, the decision should be based on the individual patient’s symptoms, the characteristics of the growth, and the physician’s evaluation.

When Should You See a Doctor About a Lipoma?

Any unexplained or changing lump is worth discussing with a medical professional. Prompt evaluation is especially important for a mass that is rapidly enlarging, painful, unusually firm, deep, fixed in place, or associated with other concerning changes.

For patients in need of evaluation for a lipoma or other soft-tissue mass, Dr. Glenn Sandler can assess the growth, determine whether further testing is appropriate, and discuss whether removal may be beneficial.

A lipoma may be harmless, but understanding what a lump is and monitoring changes can provide important peace of mind. When removal is appropriate, treatment can address both medical concerns and symptoms while providing confirmation of the diagnosis.
