Lump in Butt: Top 4 Causes

Having a lump in butt isn’t a common symptom. It can be scary reaching behind and feeling a lump beneath the skin of your butt cheek.

First and foremost, don’t panic. It’s most likely a cyst or some other benign growth.

Dermatofibroma

Dermatofibromas are harmless skin masses that are reddish-brown in color.

While they most commonly appear on the arms and legs, they can also appear on the butt cheek.

Dermatofibromas are round, usually painless, and are found just beneath the skin.

Unfortunately, doctors aren’t entirely sure what causes them. Since they aren’t a medical emergency, you don’t need to remove them unless it’s bothering you.

Removing a butt lump that’s a dermatofibroma is relatively straightforward.

The doctor will either freeze it with liquid nitrogen (which makes it fall off) or they’ll surgically remove it with local anesthetic.

The only way to know if it is in fact a dermatofibroma is to visit a dermatologist.

Cyst

Your butt cheek lump is most likely due to a cyst. The important thing to know about cysts is that they are noncancerous.

Due to their benign nature, they won’t spread to other parts of the body or kill you. What’s inside a cyst? They are usually filled with pus.

They can appear pretty much anywhere on the body, including the butt. Another key characteristic about cysts is that they usually grow very slowly.

They are also smooth to the touch and painless. If your butt lump turns out to be a cyst then try not worry about it.

Cysts form whenever a sebaceous gland gets clogged or can be caused by an infection. If the cyst ruptures, keep it sterilized.

Otherwise, it can get infected. The only downside to cysts is that they don’t go away on their own. You will need to get it cut out by a dermatologist if you want it removed.

Epidermoid Cyst

Epidermoid CystEpidermoid cysts, also called sebaceous cysts, are noncancerous masses that can appear in various parts of the body.

They can develop during the outpouching of hair follicles. Epidermoid cysts are most commonly seen in areas like the chest, back, calves, and genitals.

If you have a lump on your butt, an epidermoid cyst isn’t the most likely cause. Still, you shouldn’t rule it out as a possibility.

The only way to know for sure if you have it is to get an official diagnosis. If an epidermoid cyst gets infected, then it can release pus as well as become red and tender.

Never try to drain the cyst yourself. If will simply refill if you don’t remove the entire sac (which requires a medical professional who knows what they are doing).

Lipoma

A lipoma is nothing more than a soft tissue tumor. Don’t let the word “tumor” scare you- it’s a benign growth that isn’t cancerous.

Patients often find them on their shoulders and neck. They can also appear on the butt. They’re soft, squishy, movable, and painless.

You don’t need to get a lipoma removed unless it’s bothering you. For example, while rare, some lipomas press up against nerves and cause pain.

If this is the case with your butt lump, then you may want to get it surgically removed.

While lipomas vary in size, they usually don’t get larger than 5 centimeters in length. What causes lipomas? Doctors don’t really know.

They believe that it’s largely dependent on genetics, but recent evidence is showing that it can also be linked to other factors like diet, activity level, and stress.

Does Your Lump in Butt Hurt?

Most lumps that appear thorugout the body don’t cause any pain.

Unfortunately, this might not be the case with a butt lump. Due to its location, whenever you sit, you will be putting a lot of pressure on the lump.

This may or may not be painful depending on its exact location. It’s also possible to pop open the lump if it’s close enough to the surface of the skin.

Lumps that are deeper beneath the skin of your butt cheek aren’t as likely to break open due to all the extra cushioning.

If your lump is causing you pain, then it’s recommended that you see a dermatologist as soon as possible.

Bottom Line

If you feel a lump in your butt, then don’t panic. It’s most likely not cancerous. It’s more likely to be a benign skin growth like a lipoma or cyst.

Skin growths happens for a variety of reasons and it can be difficult to trace the exact cause.

If your lump hasn’t gone away after a week or two, then schedule a visit with a medical professional. They’ll look at and palpate your lump to determine what it is.

If they suspect cancer, then they’ll give you a biopsy. Fortunately, it’s very rare that a butt cheek lump is going to be cancerous.
