Ear cancer is when abnormal cells in the ear start to grow and divide in an uncontrolled way. Most of these cancers start in the skin of the outer ear. Between 6 and 10 out of 100 skin cancers (between 6 and 10%) develop on the outer ear.

Ear cancer often starts as a skin cancer on the outer ear that then spreads throughout the various ear structures, including the ear canal and the eardrum. This rare cancer can also start from within the ear.
Ear cancer can affect both the inner and external parts of the ear. It often starts as a skin cancer on the outer ear that then spreads throughout the various ear structures, including the 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. The temporal bone also includes the mastoid bone. This is the bony lump you feel behind your ear.
Ear cancer is very rare. Only about 300 people in the United States are diagnosed with it each year. In contrast, more than 250,000 new cases of breast cancer are expected to be diagnosed in 2018, according to the National Cancer Institute.
Skin cancers
•Basal cell carcinoma affects the basal layer cells of the epidermis, or the outermost layer of skin. •Squamous cell carcinoma affects the squamous cells of the epidermis. It’s the most common 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 a 15 percent chance of spreading, according to a 2016 case report. •Melanoma affects the skin’s melanocyte cells. These cells give the skin a brown color when you’re 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. It’s considered the most serious form of skin cancer. Melanoma of the ear accounts for 1 percent 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 only 5 percent 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.
Outer ear
The outer ear 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 the ear canal include: •lump in or near the entrance to the ear canal •hearing loss •discharge from the ear
Middle ear
Signs of skin cancer in the middle ear include: •discharge from the ear, which may be bloody (most common symptom) •hearing loss •ear pain •numbness on the affected side of the head
Researchers aren’t exactly sure what causes ear cancer. So few cases exist, it’s 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. This increases your risk of skin cancer in general.
•Spending time in the sun without (or with inadequate amounts of) sunscreen. This puts you at greater risk for skin cancer, which can then lead to ear cancer.
•Having frequent ear infections. The inflammatory responses that accompany ear infections may somehow impact cellular changes that prompt cancer.
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 a biopsy. A biopsy may be done under local or general anesthesia (so you don’t feel any pain), depending on the location of the affected area.
Treatment generally depends on the size of the cancerous growth and where it’s 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.
Ear cancer is exceedingly rare. Survival rates vary depending on the location of the tumor and how long it’s progressed.
It’s 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 a long-term (or recurrent) ear infection, especially one without a cold or other congestion.
Many doctors misdiagnose ear cancers as ear infections. This misdiagnosis gives the tumor opportunity to grow. Thus, it becomes harder to effectively treat.

It includes the soft part of the roof of the mouth (soft palate), the base or the back of the tongue (the part you cannot see), the tonsils and the side walls of the throat. The most common type of oropharyngeal cancer is squamous cell cancer.
Overview. What is an ear tumor? 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.
1 means that less than half (50%) of the cancer is dying tissue (necrosis). 2 means that more than half (50%) of the cancer is dying tissue (necrosis). Grades. The scores for differentiation, mitotic count and necrosis are added together to give the grade.
