What Is a Skin Lump?

Signs and Symptoms of Skin Lumps

Skin lumps can have many causes that affect how they look or feel. The following are some signs and symptoms that define a skin bump, says Rebecca Hartman, MD, MPH, a cutaneous oncologist at Dana-Farber Cancer Institute in Boston. Keep in mind that a single lump can’t match all the descriptions on this wide-ranging list.

A lump that feels soft, mushy, or squishy
A lump that feels mobile
A lump that’s fixed
A firm lump
A lump that feels hard
A lump that’s red and inflamed
A painful lump
A lump that has a central pore
A lump that looks well-defined under the skin
A lump that has an irregular contour
A lump that is growing

In addition, depending on the cause, you could experience other symptoms along with the skin lump. For instance, one sign of lymphoma, or cancer of the lymphatic system, is enlarged lymph nodes in your armpits, neck, or groin, along with fever and night sweats.

Causes and Risk Factors of Skin Lumps

A “skin lump” is a specific symptom of a medical condition, so the cause behind it depends on exactly what the skin lump is.

“Skin lumps” can be divided into three different categories, says Dr. Seminario-Vidal:

Benign: The lump is noncancerous and may not require any treatment.
Inflammatory or infectious: The lump requires treatment but is not life-threatening.
Malignant: These are cancerous and would require treatment in the short-term (rather than a wait-and-see approach).

Skin Tag

This is one of the most common causes of a skin lump, says Dr. Hartman, and they often appear on the face or back. “These are smooth and mobile, are oval with a defined border, and they aren’t entirely squishy, but they’re not firm and hard either,” she explains.

The giveaway sign of a cyst is a lump with a central pore.

This happens when skin does not mature properly and folds into itself, forming the pore. Dr. Hartman advises that not all cysts will have a visible pore. Cysts might become red and painful or secrete fluid if inflammation or an infection develops. If you suspect you have an infected cyst, seek medical care.

Wart

These are skin growths that develop because of human papillomavirus (HPV).

More than 100 different types of HPV can pass between humans, and they don’t cause symptoms in most people.

But when HPV causes symptoms, they develop in the form of warts. Many types of warts can develop, often appearing on the hands, feet, or genitals.

They are contagious, meaning that contact with a wart can transmit HPV. The most common type of wart has an almost cauliflower-like appearance.

Dermatofibroma

Lymph nodes are part of your body’s immune system and are located in certain parts of the body, such as your armpit, groin, or below your chin in your neck.

These can swell if you get sick, as immune cells gather there to fight off an infection. Common infections that lead to swollen lymph nodes include strep throat, measles, ear infections, a dental abscess, mononucleosis (mono), skin infections, and human immunodeficiency virus (HIV).

Seminario-Vidal adds that lymph nodes in the groin may also enlarge and become inflamed due to extreme exercise, such as participating in a long endurance event like a marathon. You should seek medical attention if your lymph nodes feel or appear swollen.

Lymph nodes shrink to their normal size after recovery from an infection. They should still feel smooth and mobile. But a lymphoma, or cancer in the lymph node, may become firm or hard and fixed. Cancer may cause symptoms alongside swollen lymph nodes like decreased appetite, weight loss, fever, and chills.

Diagnosis of Skin Lumps

Your dermatologist can perform a physical exam to diagnose your skin lump. If they note something concerning (for example, a skin lump or bump growing), they will likely recommend a biopsy, says Seminario-Vidal.

A dermatologist can take the biopsy depending on the lump’s location or how deep it is under the skin. In areas where the skin is particularly thick, like the back, a plastic surgeon may have to open up the skin under local anesthesia, she says. If the lump is extremely deep, an individual may need general anesthesia for the biopsy.

Doctors may first evaluate deeper lesions or potentially cancerous lumps with imaging, such as a computed tomography (CT) scan, magnetic resonance imaging (MRI) scan, or ultrasound scan.

Prognosis of Skin Lumps

The outlook of a skin lump depends on the cause and whether it is benign, potentially cancerous, or cancerous. “When patients notice a lump, they’re often understandably concerned, but most are benign,” says Dr. Hartman.

Benign:

Skin tags
Cysts
Lipoma
Warts
Dermatofibroma
Enlarged lymph node, if caused by a viral infection, like the common cold

Possibly cancerous:

New, changing, itching, or bleeding spot, lesion, or bump on the skin, which could point to a nonmelanoma or melanoma skin cancer

Cancerous:

Dermatofibrosarcoma
An enlarged lymph node, if caused by lymphoma, or cancer of the lymph system

But even people with cancerous skin lumps can improve their outlook if they seek treatment before it has a chance to spread. The outlook for cancers that cause skin lumps, including lymphoma, depends on:

The type of lymphoma
A person’s age
A person’s overall health status

According to Cleveland Clinic, lymphoma treatment often reduces lymphoma symptoms for long periods or cures lymphoma.

Duration of Skin Lumps

How long skin lumps stick around and recovery time completely depends on what has caused the skin lump and whether removal is necessary.

Some issues, like skin tags, will be lifelong and typically do not need treatment unless they cause a problem like catching on clothing.

A red, painful inflamed cyst may shrink over a few days as inflammation subsides,

but a cyst will need treatment if the patient would like to get rid of it permanently, says Hartman.

Sometimes, Hartman may suggest leaving a cyst alone if the location of the lump, such as the face, means that treatment could be more disfiguring than the cyst itself. Surgeons also typically do not remove lipomas, adds Hartman, unless they are large, growing, or bothersome.

Treatment for Skin Lumps

Many skin lumps won’t resolve without treatment. Often, however, the lump is not dangerous and does not need treatment if it does not cause functional problems.

Skin Tag Skin tags are benign and do not need to be removed, but a dermatologist removes skin tags using one of three methods:

Snip excision
Cautery
Cryosurgery, or the use of a cold liquid, like liquid nitrogen, to freeze the skin tag

It’s best not to remove a skin tag yourself, as they can bleed when taken off.

Cyst Removal is necessary to get rid of a cyst, says Hartman. She advises against taking matters into your own hands. “I tell people not to pop them. Squeezing it may press out keratin, but that does not eliminate the problem and may make it worse by causing more inflammation,” she says.

Your doctor can cut out the cyst to remove its wall, or lining, as this prevents it from coming back.

They may delay surgery if the cyst shows signs of inflammation.

Doctors can also drain cysts as a temporary solution and give a cyst a steroid injection to help calm the inflammation.

Wart It may take quite a while (potentially years), but your wart will eventually resolve without treatment.

At home, you can use an over-the-counter wart removal kit that includes salicylic acid.

At the doctor’s office, they can freeze off warts with liquid nitrogen.

Dermatofibroma (DFSP) These are benign, but surgical removal is an option.

If dermatofibrosarcoma develops, surgery can remove it, although a doctor may also request radiation or targeted therapy drugs to destroy any cancer cells that remain after surgery.

Lipoma If a patient has many lipomas, doctors usually recommend not removing them, says Hartman. If the lipoma is large, growing, or bothersome, a doctor can use surgery to remove it.

The minor procedure requires an injection to numb the area but takes just 30 minutes, she says.

Enlarged Lymph Node You don’t need to treat an enlarged lymph node itself, but treatment is necessary for the underlying cause. If lymph nodes have swollen because you have a viral infection like a cold, they should return to their standard size once you recover, says Hartman. That said, if you find an enlarged lymph node that’s 1 centimeter (cm) or less in diameter, it’s soft, and you can move it around, that’s less concerning, says Seminario-Vidal. Doctors may take a wait-and-see approach and follow up to make sure it’s gone down.

If you receive a lymphoma diagnosis, then you will receive the appropriate cancer treat, which may include chemotherapy, radiation, targeted drugs, and a bone marrow transplant.

Integrative and Complementary Approaches

For many lumps, there is little you can do at home. But a warm compress on a red and angry cyst can relieve inflammation and ease soreness, says Hartman.

When it comes to warts, many alternative treatments have circulated, some mainstream (duct tape), while others are more radical (distance healers that channel energy into the wart).

None of the homeopathic remedies are effective, and warts should resolve without treatment once the body develops an immune response.

Prevention of Skin Lumps

Many skin lumps, like lipomas, may have a genetic cause, says Hartman. That’s one reason why you won’t be able to take steps to actively prevent all skin lumps. To avoid skin lumps or bumps that could be a type of skin cancer, it’s crucial to wear a broad-spectrum sunscreen with at least SPF 15 every day.

When it comes to cysts, you won’t be able to prevent them from forming, but make sure you don’t try to “pop” a cyst yourself, to avoid infection and scarring.

Skin tags aren’t always preventable, as they can have genetic causes. But controlling conditions like diabetes and obesity that increase the risk of skin tags will discourage their formation.

This is achievable through body weight management and effective blood glucose control.

Research and Statistics: Who Has Skin Lumps, and How Common Are They?

“Skin lumps” are a common symptom. Here are some statistics related to various types:

Skin Tag Between 50 and 60 percent of the general population have skin tags, with males and females being equal.

Cyst Epidermoid cysts are most common in people who are in their thirties and forties and occur twice as often in men than women.

Wart One-third of children and teenagers have warts, while just 3 to 5 percent of adults have warts.

Dermatofibroma These are most common in people in their twenties, thirties, and forties and may be more likely to occur in females.

Lipoma One in every 1,000 people will develop a lipoma, according to Cleveland Clinic.

You can get them at any age, but they are more likely in adults aged 40 to 60 years.Clinic.

Lymphoma In the United States, around 4% of people with cancer have non-Hodgkin lymphoma (NHL), making it one of the country’s most common cancers.

The American Cancer Society predicts that about 80,620 people will receive an NHL diagnosis in 2024.

Men account for more NHL diagnoses than women.

The Takeaway

Skin lumps take many forms, but the vast majority are noncancerous. Skin tags, lipomas, and cysts only need treatment if they’re causing significant problems, and warts tend to heal by themselves over time. Enlarged lymph nodes can point to an underlying infection or disease but tend to resolve when a person manages the disease, and dermatofibromas are generally benign.

Swollen lymph nodes may sometimes point to lymphoma, but treatment can help to send the disease into remission or cure it completely. If lumps are causing concern, seek a clinical opinion — even if the lump is harmless, it’s best to rule out anything more serious.
