As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more.

What body system does melanoma affect?

Melanoma is a cancer of melanocytes, cells that produce the pigment melanin. Although most melanomas develop on the skin, they can originate in almost any organ including the eye, brain, and lymph nodes. It is not unusual for patients or their spouses to recognize cutaneous (skin) melanomas.

Are skin cancers always dark?

Melanomas are usually brown or black, but some can appear pink, tan, or even white. Some melanomas have areas with different colors, and they might not be round like normal moles. They might grow quickly or even spread into the surrounding skin.

Stage I melanoma is no more than 1.0 millimeter thick (about the size of a sharpened pencil point), with or without an ulceration (broken skin). There is no evidence that Stage I melanoma has spread to the lymph tissues, lymph nodes, or body organs.

Does skin cancer hurt to the touch?

It may feel itchy, tender, or painful. Basal cell and squamous cell skin cancers can look like a variety of marks on the skin. The key warning signs are a new growth, a spot or bump that’s getting larger over time, or a sore that doesn’t heal within a few weeks.

Where does Melanoma usually spread to first?

Normally, the first place a melanoma tumor metastasizes to is the lymph nodes, by literally draining melanoma cells into the lymphatic fluid, which carries the melanoma cells through the lymphatic channels to the nearest lymph node basin.

How can you tell melanoma?

Spread of pigment from the border of a spot into surrounding skin. Redness or a new swelling beyond the border of the mole. Change in sensation, such as itchiness, tenderness, or pain. Change in the surface of a mole – scaliness, oozing, bleeding, or the appearance of a lump or bump.
