What is Melanoma? Melanoma, a grave variant of skin cancer originating from melanocytes, is less prevalent compared to basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), but it presents a heightened threat due to its proclivity for rapid metastasis if not addressed promptly in its initial stages. Emerging from pigment-producing cells, melanoma manifests as irregular moles or dark patches on the skin. The urgency of early detection cannot be overstated, as this cancer possesses the potential to disseminate swiftly to other organs. Unlike the more common BCC and SCC, malignant melanoma demands heightened vigilance and timely intervention. Regular skin examinations and prompt medical attention are crucial in mitigating the risks associated with this formidable form of skin cancer.
There are many types of Melanoma Skin Cancer, such as...
Represents about 70% of skin melanomas.
Typically grows outward on the skin surface initially.
May originate from existing moles or appear as a changing dark spot.
Nodular Melanoma:
Accounts for approximately 20% of skin melanomas.
Appears as a distinct, raised bump on the skin.
Often dark brown or black, but can also be pink or red.
Tends to grow downward into deeper skin layers early, often detected at an advanced stage.
Lentigo Maligna Melanoma:
Commonly seen in older individuals.
Initially presents as an abnormally shaped tan or brown spot in sun-exposed areas.
Shows slow growth or other changes over time.
Acral Lentiginous Melanoma (Acral Melanoma):
Originates in areas with minimal sun exposure, such as palms, soles, or under the nails.
Particularly prevalent in individuals with darker skin tones.
Represents a significant proportion of melanomas in this population.
Signs of Melanoma Skin Cancer: the ABCDE rule
The primary and crucial indication of melanoma involves the appearance of a new spot on the skin or a spot undergoing alterations in its size, shape, or color.
This ABCDE rule serves as a guide to recognize the common signs of melanoma, providing specific criteria to be mindful of when assessing skin spots.
A is for Asymmetry:
One half of a mole or birthmark doesn't match the other.
B is for Border:
Edges are irregular, ragged, notched, or blurred.
C is for Color:
Color variations with different shades of brown or black, or patches of pink, red, white, or blue.
D is for Diameter:
Spot larger than 6 millimeters across (about ¼ inch), although melanomas can occasionally be smaller.
E is for Evolving:
The mole undergoes changes in size, shape, or color.
