Ear tumors can form on your outer ear (skin cancer), inner ear or middle ear. Most ear tumors are benign (not cancerous), but they may cause hearing loss. While small benign tumors may not require treatment unless they’re causing symptoms, all cancerous tumors do. Treatments include Mohs surgery, radiosurgery and radiation therapy.

An ear tumor is a mass or lump of abnormal cells that forms in your ear. Most ear tumors are benign, or noncancerous. But some ear tumors are malignant (cancerous).

Ear tumors can form in any part of your ear, including your inner ear, middle ear or outer ear. They may affect your hearing. It’s important to get tumors checked early on, before they potentially cause long-term issues.
Both cysts and tumors can cause a bump or lump on or in your ear:
Noncancerous ear tumors can block your ear canal, leading to earwax buildup. Some types that form inside your ear can grow big enough to harm the organs that help you hear and balance:

Cancer can form inside or on the outside of your ear. But ear cancer is rare.
Most cancer that affects your ear is actually skin cancer. Approximately 6% to 10% of skin cancers start on the outer ear. Skin cancers that may affect your ear include:
Cancers that directly affect your middle or inner ear are even more uncommon:
Symptoms of an ear tumor vary depending on the tumor type and the part of your ear it affects. Signs of an ear tumor include:
Ear tumors occur when your body makes new cells faster than usual. Sometimes, old, damaged cells don’t die off the way they should. Clumps of old and new cells group together, forming a tumor.
Cancerous ear tumors occur when the cells grow uncontrollably. Untreated, these malignant cells may spread to other locations in your body (metastatic cancer).
People of all ages, including children, can get ear tumors. Factors that increase your chances of developing an ear tumor include:
Ear tumors, even ones that aren’t ear cancer, can cause hearing loss. They can cause frequent infections and impact the organs inside your ear that help you hear and balance.
Your healthcare provider can advise you on when it’s safe to monitor a tumor versus when you’ll need treatment to prevent issues like these.
Your healthcare provider may notice a tumor by examining your ear during a physical exam. They may refer you to an audiologist (hearing specialist) for a hearing test. You’ll likely also see an ear, nose and throat doctor (an ENT or otolaryngologist) who specializes in ear disorders.

If your provider suspects your ear tumor may be cancerous, they’ll perform a biopsy. This procedure removes the tumor or cells from the tumor. A pathologist (a doctor who studies diseases) examines the samples in a lab to make a diagnosis.
Because inner ear tumors are difficult to reach and biopsy, your provider may order a CT scan or MRI to learn more about them. In rare cases, you may need surgery to remove the tumor before a provider can diagnose it.
Some noncancerous ear tumors don’t need treatment unless the tumor affects your hearing or balance. Your healthcare provider may monitor the tumor to keep an eye on its growth and check in with you about any symptoms you’re experiencing.
The most common treatments remove the growth through surgery or other methods. For example, providers often use radiosurgery (gamma knife surgery) to remove benign ear tumors like acoustic neuromas. This procedure directs high doses of radiation directly to the tumor. It’s not surgery, but it removes tumors with surgical-like precision.
To treat keloids, your healthcare provider may inject the tumor with a corticosteroid. Some keloids require surgical removal followed by radiation therapy to destroy any remaining cells.

Dermatologists (doctors who specialize in skin diseases) treat skin cancer on the outer ear. Treatment for cancerous ear tumors depends on the cancer type and location. Treatment might include:
Small ear tumors that aren’t causing symptoms may not need treatment at all. But if a tumor is causing hearing loss or other issues, you may need surgery to remove it. Most people who get surgery or other treatments for benign ear tumors recover well.
The prognosis for ear cancer depends on things like the type of tumor, where it’s located and its stage (how much it’s spread). But even with melanoma (the deadliest form of skin cancer), the five-year survival rate is 99% when surgery removes the cancer before it’s spread.
Skin cancer on your outer ear can sometimes come back and spread to other parts of your body. You’ll need regular skin exams to keep an eye out for returning cancer.

A note from Cleveland Clinic
Most ear tumors are benign (not cancer) and don’t need treatment. But if a benign ear tumor affects your hearing or balance, you may need radiosurgery to get rid of it. Most cancerous ear tumors are actually skin cancers. These cancers require treatment. You should contact a healthcare provider if you notice changes in your hearing, feel a lump in or on your ear, or notice skin changes to your ear.
