Frequent question: What cells and tissues are affected by melanoma?

·

What cells type does melanoma affect?

Melanocytes: These are the cells that can become melanoma. They normally make a brown pigment called melanin, which gives the skin its tan or brown color. Melanin protects the deeper layers of the skin from some of the harmful effects of the sun.

What type of tissue does melanoma occur within?

The skin’s layers include the epidermis (outer layer), dermis (inner layer) and hypodermis (subcutaneous tissue). Melanoma typically develops in the epidermis, which contains melanocytes.

What body systems does melanoma affect?

Melanoma can spread to parts of your body far away from where the cancer started. This is called advanced, metastatic, or stage IV melanoma. It can move to your lungs, liver, brain, bones, digestive system, and lymph nodes. Most people find their skin cancer early, before it has spread.

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 does melanoma affect the tissue?

Treating melanoma

How deeply a melanoma has invaded nearby tissues affects the outlook. If it has invaded only nearby tissue, it can be cured. But if melanoma cells have broken away and traveled through the lymph vessels to nearby lymph nodes and then spread (metastasized) to other organs, the disease can be deadly.

Does melanoma show up in blood tests?

Blood tests aren’t used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.
