Ear Cancer Symptoms and Treatment, can affect both the inner and external parts of the ear. It often starts as a skin cancerĀ on the outer ear that then spreads throughout the various ear structures, including theĀ ear canal and the eardrum. Ear cancer may also start from within the ear. It can affect the bone inside the ear, called the temporal bone. TheĀ temporal bone also includes the mastoid bone. This is the bony lump you feel behind your ear. Ear cancer is very rare. Only aboutĀ 300 peopleĀ in the United States are diagnosed with it each year. In contrast, more thanĀ 250,000 new cases of breast cancerTrusted SourceĀ are expected to be diagnosed in 2018, according to the National Cancer Institute.

Several different types of cancer can affect the ear. These include the following:
Skin cancers
- Basal cell carcinomaĀ affects the basal layer cells of the epidermis, or the outermost layer of skin.
- Squamous cell carcinomaĀ affects the squamous cells of the epidermis. Itās theĀ most commonĀ type of ear cancer. It grows deeper into the cells of the body and is more likely than basal cell carcinoma to spread to other tissues. Squamous cell carcinomas that affect the outer cartilage of the ear have about aĀ 15 percentĀ chance of spreading, according to a 2016 case report.
- MelanomaĀ affects the skinās melanocyte cells. These cells give the skin a brown color when youāre exposed to the sun. While melanoma is a less common form of skin cancer than basal or squamous cell carcinoma, it tends to be aggressive. Itās considered the most serious form of skin cancer. Melanoma of the ear accounts forĀ 1 percentĀ of melanoma cases, notes a 2006 review.
Adenoid cystic carcinoma
This very rare type of cancer typically affects the salivary glands, but can also be seen in the ear. A 2013 case report estimates that these tumors account for onlyĀ 5 percentĀ of cancers of the external auditory canal (the passageway from the outside of the head to the eardrum).
Parotid tumors
Malignant growths of the parotid gland can spread to the ear canal. This gland is the largest salivary gland in the body.
The symptoms of ear cancer vary depending on what part of your ear is affected.
Outer ear
TheĀ outer earĀ includes the earlobe, ear rim (called the pinna), and the outer entrance to the ear canal.
Signs of skin cancer in the outer ear include:
- scaly patches of skin that remain, even after moisturizing
- pearly white lumps under the skin
- skin ulcers that bleed
Ear canal
Signs of skin cancer in theĀ ear canalĀ include:
- lump in or near the entrance to the ear canal
- hearing loss
- discharge from the ear
Middle ear
Signs of skin cancer in theĀ middle earĀ include:
- discharge from the ear, which may be bloody (most commonĀ symptom)
- hearing loss
- ear pain
- numbness on the affected side of the head
Inner ear
Signs of skin cancer in theĀ inner earĀ include:
- ear pain
- dizziness
- hearing loss
- ringing in ears
- headache
Researchers arenāt exactly sure what causes ear cancer. So few cases exist, itās hard to figure out how it may originate. But researchers do know that certain things may increase your chances of developing ear cancer. These include:
- Being light-skinned.Ā This increases your risk of skin cancer in general.
- Spending time in the sun without (or with inadequate amounts of) sunscreen.Ā This puts you at greater risk for skin cancer, which can then lead to ear cancer.
- Having frequentĀ ear infections.Ā The inflammatory responses that accompany ear infections may somehow impact cellular changes that prompt cancer.
- Being older.Ā Certain types of ear cancer are more common in older individuals. InĀ one studyTrusted Source, data suggested that squamous cell carcinoma of the temporal bone is most common in the seventh decade of life.
If you have any suspicious growths on the outside of your ear or in your middle ear, your doctor can remove some of the tissue and send it to a lab to check for cancer cells.
This procedure is called aĀ biopsy. A biopsy may be done under local or general anesthesia (so you donāt feel any pain), depending on the location of the affected area.
Cancerous growths on the inner ear can be more difficult to reach. This makes it harder for your doctor to biopsy without damaging surrounding tissue. Your doctor may have to rely on imaging tests, such as anĀ MRIĀ orĀ CT scanĀ to get an idea if cancer is present.
Treatment generally depends on the size of the cancerous growth and where itās located.
Skin cancers on the outside of the ear are generally cut out. If large areas are removed, you may need reconstruction surgery.
Ear canal or temporal bone cancers require surgery followed by radiation. How much of the ear is removed depends on the extent of the tumor.
In some cases, the ear canal, bone, and eardrum have to be removed. Depending on how much is removed, your doctor may be able to reconstruct your ear.
In some cases, hearing isnāt significantly affected. In other cases, you may need to use a hearing aid.
Ear cancer is exceedingly rare. Survival rates vary depending on the location of the tumor and how long itās progressed.
Itās important to have any growths around your ears examined by a healthcare provider. Do the same for any ear drainage or unexplained ear pain.
Seek the advice of an ear, nose, and throat specialist (ENT) if you have what seems to be aĀ long-term (or recurrent) ear infection, especially one without a cold or other congestion. Ear Cancer Symptoms and Treatment
Many doctors misdiagnose ear cancers as ear infections. This misdiagnosis gives the tumor opportunity to grow. Thus, it becomes harder to effectively treat. Ear Cancer Symptoms and TreatmentĀ
Get a second opinion if you suspect ear cancer. Early detection is key to a good outlook.
