  5. Melanoma stages vs. survival rate

  6. Melanoma types • Superficial spreading melanoma -commonly found on the arms, legs, chest and back. The melanoma cells usually grow slowly at first, and spread out across the surface of the skin. • Nodular melanoma - can grow more quickly than other melanomas. It is also more likely to lose its colour when growing, becoming red rather than black. It is more commonly found on the chest, back, head or neck. • Lentigo maligna melanoma - usually found in older people, in areas of skin that have had a lot of sun exposure over many years. It is often found on the face and neck. • Acral lentiginous melanoma - usually found on the palms of the hands, soles of the feet, or under fingernails or toenails. It is more common in people with black or brown skin. It is not thought to be related to sun exposure.

  7. Pie chart demonstrating the percentagedistribution of genes with clinically-relevant and recurrent driver mutations in individuals with melanoma, including non-V600 BRAF alterations (left), interrogated on the Vanderbilt melanoma SNaPshotassay. BRAF fusionsoccur in approximately 4–8% “pan-negative” cases (right).
