Does melanoma pop up overnight?

While some skin cancer lesions appear suddenly, others grow slowly over time. For example, the crusty, pre-cancerous spots associated with actinic keratoses can take years to develop. Other forms of skin cancer, like melanoma, can appear very suddenly, while at other times, the lesions can vanish and reappear.

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 is melanoma treated if caught early?

Treatment for early-stage melanomas usually includes surgery to remove the melanoma. A very thin melanoma may be removed entirely during the biopsy and require no further treatment. Otherwise, your surgeon will remove the cancer as well as a border of normal skin and a layer of tissue beneath the skin.

How long does it take for melanoma to spread?

Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun.
