How long before a mole turns into melanoma?

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.

What are the chances of a mole turning cancerous?

I was Diagnosed with Skin Cancer. (Melanoma)

What does Stage 1 melanoma look like?

Stage IA Melanoma: The melanoma tumor is less than 1.0 millimeter thick (less than the size of a sharpened pencil point) with or without ulceration (broken skin) when viewed under the microscope. Stage IB Melanoma: The melanoma tumor is more than 1.0 millimeter and less than 2.0 millimeters thick without ulceration.

What does early stage melanoma look like?

What to look for: Usually, the most obvious warning signs of early stage melanoma are changes to your moles or spots: in size, shape, colour or in how they look or how they feel. Melanoma can also appear as a new mole (more commonly in people aged 50 years or more)².

What happens if a cancerous mole goes untreated?

In particular, BCCs rarely spread beyond the initial tumor site. However, left untreated, BCCs can grow deeper into the skin and damage surrounding skin, tissue, and bone. Occasionally, a BCC can become aggressive, spreading to other parts of the body and even becoming life threatening.

Does melanoma show up in blood work?

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.

Can melanoma appear overnight?

How thick is melanoma in situ?

This stage is also known as melanoma in situ. The tumor is more than 1 mm thick (T2b or T3) and may be thicker than 4 mm (T4). It might or might not be ulcerated. The cancer has not spread to nearby lymph nodes (N0) or to distant parts of the body (M0).
