What is the invasive characteristic of malignant melanoma?

Answer 1

Early signs of melanoma are changes to the shape or color of existing moles or in the case of nodular melanoma the appearance of a new lump anywhere on the skin (such lesions should be referred without delay to a dermatologist). At later stages, the mole may itch, ulcerate or bleed. Early signs of melanoma are summarized by the mnemonic "ABCDE":

• Asymmetry
• Borders (irregular)
• Color (variegated), and
• Diameter (greater than 6 mm (0.24 in), about the size of a pencil eraser)
• Evolving over time

These classifications do not however apply to the most dangerous form of melanoma nodular melanoma which has its own classifications:

• Elevated above the skin surface
• Firm to the touch
• Growing.

Answer 2

Melanoma usually looks like a dark brown or black blotch on the skin, 6 mm (3/8") or more in size, that grew in less than a year. It is usually irregular in size (not oval) and its color is irregular.

A lesion that fits this description should be removed by a dermatologist and examined by a pathologist.

Answer 3

There are several symptoms of melanoma cancer. Some of these include: unusual moles and changes in the unusual mole, itching, oozing, or bleeding of the mole. Hidden melanomas are more common in darker people.

Answer 4

The characteristics of melanoma are Asymmetry, Border irregularity, Color, Diameter

Answer 5

Melanomas typically have a combination of colors, including tan, brown, black, or gray; there may also be a dull pink or rose pigmentation within a small area of the lesion.

Answer 6

The locally invasive characteristic of this tumor involves vertical penetration through the skin and into the dermis and subcutaneous (under-the-skin) tissues of the malignant melanocytes.
