Question: Is Merkel cell cancer hereditary?

Does Merkel cell carcinoma run in families?

MCC does not seem to run in families, so the DNA changes that lead to MCC are not likely passed on (inherited) from a person’s parents. Instead, these changes probably happen during the person’s life. Sometimes these changes might just be random events that happen inside cells, without having an outside cause.

Is Merkel cell carcinoma fatal?

Merkel cell carcinoma, or MCC, is a rare skin cancer that can be fatal, killing about 700 people per year. It occurs more commonly in people frequently exposed to ultraviolet light. Most cases of MCC show up first with a small red or purple bump on the skin.

How fast does Merkel cell cancer spread?

A lesion of metastatic MCC may appear as a 1-3 cm, flesh-colored to red-purple bump that feels firm, is deeper compared to the primary lesion, and grows rapidly over a period of 2-4 weeks.

What causes Merkel cancer?

The risk factors for Merkel cell cancer are: Being exposed to a lot of ultraviolet (UV) rays from the sun or other sources such as tanning beds or PUVA treatments. Not protecting your skin from the sun. Having light-colored skin.

Why is Merkel cell carcinoma so rare?

Merkel cell carcinoma (MCC) is 40 times more rare than melanoma, with an estimated one case per 130,000 people in the U.S. Risk factors for MCC include sun exposure, fair skin, age over 50 and a weakened immune system.

What viruses causes Merkel cell carcinoma?

Researchers recently discovered that a common virus plays a role in causing most cases of Merkel cell carcinoma. The virus (Merkel cell polyomavirus) lives on the skin and doesn’t cause any signs or symptoms.

What is the mortality rate of Merkel cell carcinoma?

Merkel cell carcinoma (MCC) is an aggressive neuroendocrine tumor of the skin with a rising incidence. MCC has metastatic potential regardless the size of the primary tumor and a 5-year disease associated mortality rate is 46 %.

Is Merkel cell curable?

Merkel cell carcinoma is highly treatable with surgical and nonsurgical therapies, particularly if caught early. Treatments are often highly individualized, depending on a patient’s general health, as well as the tumor’s location, size, depth, and degree of spread.

How bad is Merkel cell cancer?

Any distant metastatic Merkel cell carcinoma is very serious and has a very poor prognosis. Treatment of the metastatic disease is aimed at improving quality of life. In some cases, radiotherapy and/or systemic chemotherapy may be administered for treatment.

What type of cancer is Merkel?

Also called neuroendocrine carcinoma of the skin or trabecular cancer, Merkel cell carcinoma is a very rare type of skin cancer that forms when Merkel cells grow out of control. The disease starts most often in areas of skin exposed to the sun, especially the head and neck, as well as the arms, legs, and trunk.

What is the most aggressive type of skin cancer?

Melanoma is a serious form of skin cancer that begins in cells known as melanocytes. While it is less common than basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage.
