Is oral melanoma a cancer?

·

What is oral melanoma?

An oral melanoma is an abnormal proliferation and replication of the cells called melanocytes). Melanocytes are cells in the skin that produce pigment, typically black in color. Amelanotic melanoma is a type of tumor arising from melanocytes, but these do not produce pigment.

Can you survive oral melanoma?

The prognosis for patients with oral malignant melanoma is poor, with the 5-year survival rate at 10-25%. Early recognition and treatment (surgical ablation) greatly improves the prognosis.

How common are oral melanomas?

Oral blue nevi are not reported to undergo malignant transformation. Oral melanomas are uncommon (1.2 cases per 10 million population per year in the United States), and, similar to their cutaneous counterparts, they are thought to arise primarily from melanocytes in the basal layer of the squamous mucosa.

How do you get rid of oral melanoma?

Treatment options for oral melanomas include: Surgery. Radiation therapy. Chemotherapy.

Chemotherapy

  1. Non-surgically excisable tumors.
  2. Tumors with the presence of metastatic disease (spread to other organs)
  3. After surgery or radiation therapy.

How do I know if I have oral melanoma?

Oral melanomas are often silent with minimal symptoms until the advanced stage. The lesions can appear as pigmented dark brown to blue-black lesions or apigmented mucosa-colored or white lesions on physical examination. Erythema may be present if inflammation is present.

Can melanoma be cured?

A cure is often possible. Melanoma is found in the outer layers of skin and in the lower layers of the dermis. The likelihood of a cure is still good. The cancer cells have spread beyond the skin and are found in a lymph node(s) or lymph vessel(s) closest to where the melanoma began.

Can you get melanoma in mouth?

In the oral cavity, malignant melanoma almost exclusively occurs in the palate and maxillary gingiva with an incidence of 80% and 91.4%, respectively. [18,19] There are very few reported cases of malignant melanoma on the mandibular gingiva.

What causes oral mucosal melanoma?

It arises primarily from melanocytes found in the basal cell layer of the epithelium, but may sometimes arise from melanocytes residing in the lamina propria. The pathogenesis is complex, and few of the molecular mechanisms underlying the development of oral mucosal melanoma have been defined.

Can you get melanoma on your tongue?

Melanoma of the tongue is specifically uncommon and represents less than 2% of all oro-nasal melanoma cases. A review of literature revealed fewer than 30 reported cases of primary malignant melanoma of the tongue.

How many years does it take for melanoma to spread?

Melanoma can grow very quickly. It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.

Can you have melanoma for years and not know?

How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.

How do you know if melanoma has spread?

For people with more-advanced melanomas, doctors may recommend imaging tests to look for signs that the cancer has spread to other areas of the body. Imaging tests may include X-rays, CT scans and positron emission tomography (PET) scans.

How long can you live with melanoma untreated?

Survival for all stages of melanoma

almost all people (almost 100%) will survive their melanoma for 1 year or more after they are diagnosed. around 90 out of every 100 people (around 90%) will survive their melanoma for 5 years or more after diagnosis.
