Moles vs. Skin Melanoma
Moles: A mole, also known as nevus, is a benign tumor that doesn’t contain cancerous cells and does not pose any health risk. Most moles typically occur in childhood or adolescence and do not change their size, shape or color.
The nevi can be removed through surgery, but only if they cause discomfort or are unaesthetic. Moles are not a cause for worry; however, if you have more than 50 moles on your body, you are more prone to developing melanoma.
Skin Melanoma: The skin melanoma is an aggressive form of skin cancer. The melanoma is a colored tumor with asymmetrical shape that grows at a fast rate and may spread to other areas of the body. The melanoma may start off by looking just like a mole, but will develop quickly and may change its shape, size and color. Melanomas may bleed.
There are several types of melanomas including superficial spreading melanoma, nodular melanoma (black), lentigo maligna (flat, freckled like spots), acral lentiginous melanoma (dark patch) or amelanotic melanomas (pinkish).
You should check your body for tumors on a regular basis, making sure to look at areas that are less visible; use 1 or 2 mirrors to help you. The sooner a melanoma is detected, the higher chances of recovery.
A good way to distinguish between moles and melanomas is to use the ABCDE rule. This is a guide that should be used whenever you detect a growth on the surface of your skin.
A for asymmetry: If the tumor is asymmetrical, there are high chances that it is a melanoma. Moles usually have a regular shape
B for border: Melanomas may have irregular borders, while moles have rounded and regular edges
C for color: Melanomas have uneven coloration and may change their color. Moles are typically pink or brown and evenly colored and will not change their coloration
D for diameter: Melanomas are typically larger than 6 millimeters (the size of a pencil eraser) and may expand. Moles are smaller in size and will not grow
E for evolution: Melanomas evolve in a short period of time (within weeks). Moles remain constant for years and rarely if ever grow.
The ABCDE guide is a good starting point. There may be some deviations so dermatologist is the person to guide you.
