But size is not a sure sign of melanoma. A healthy mole can be larger than 6mm in diameter, and a cancerous mole can be smaller than this. Credit: See a GP as soon as possible if you notice changes in a mole, freckle or patch of skin, particularly if the changes happen over a few weeks or months.
What does a small melanoma mole look like?
Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders. C is for Color. Multiple colors are a warning sign.

Can a 1mm mole be melanoma?
Melanoma stages are described as: Stage 0 – the melanoma is on the surface of the skin. Stage 1A – the melanoma is less than 1mm thick. Stage 1B – the melanoma is 1mm to 2mm thick, or less than 1mm thick and the surface of the skin is broken (ulcerated) or its cells are dividing faster than usual.
How small can a skin cancer mole be?
The edges are irregular, ragged, notched, or blurred. The color is not the same all over and may include shades of brown or black, sometimes with patches of pink, red, white, or blue. The spot is larger than ¼ inch across – about the size of a pencil eraser – although melanomas can sometimes be smaller than this.
What is considered a small melanoma?
The observational arm of the Collaborative Ocular Melanoma Study defined a small choroidal melanoma as being 1–3 mm in thickness and 5–16 mm in LBD; tumors smaller than this were regarded as probable nevi.
Is melanoma raised or flat?
The most common type of melanoma usually appears as a flat or barely raised lesion with irregular edges and different colours. Fifty per cent of these melanomas occur in preexisting moles.
What does Stage 1 melanoma look like?
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.
Can melanoma be 2mm?
In this paper, the term “micromelanoma” is coined to represent melanomas under 2 mm. The presentation is also unusual because of the age and clinical presentation of this lesion not being clinically different to the patient’s other nevi. Further this patient had <5 nevi overall.
Can melanoma be 1 mm wide?
Melanomas are often larger than 6 mm (1/4 inch) in diameter. However, with increased awareness about early detection, about 30% of melanomas are found when they are less than 6 mm in diameter.
How do you know if a mole is melanoma?
What Should I Look for When Examining My Moles?
- Asymmetry: One half of the mole does not match the other half.

Can a melanoma be very small?
Such small melanomas have a reported frequency of 11.4–38.2% of all melanomas [3–6]. One review in particular, published in 2004, found that small melanomas include less than 1 to 38% of all invasive melanomas  and it recommended that the ABCD acronym be modified to ABCDE with “E” to stand for “evolving.”

Melanoma with irregular shape and colour
Below is a very small melanoma. It is only about 4 or 5 millimetres across. But you can see clearly that it is not the same colour throughout. It also has an irregular shape.
