What Is Melanoma?

Melanoma is the most serious type of skin cancer . Often the first sign of melanoma is a change in the size, shape, color, or feel of a mole. Most melanomas have a black or black-blue area. Melanoma may also appear as a new mole. It may be black, abnormal, or "ugly looking." Thinking of "ABCDE" can help you remember what to watch for: Asymmetry - the shape of one half does not match the other Border - the edges are ragged, blurred or irregular Color - the color is uneven and may include shades of black, brown and tan Diameter - there is a change in size, usually an increase Evolving - the mole has changed over the past few weeks or months Surgery is the first treatment of.

Pathophysiology, Underlying Causes & Clinical Presentation

In Melanoma (C43.9), physiological disruption stems from tumor-suppressor loss enabling in Melanoma (C43.9: clonal proliferation), Cross-referenced with NIH MeSH (Melanoma), informing Cancer, Oncology & Supportive Care protocols that track Comprehensive Metabolic & in Melanoma (C43.9: Organ Function Panel) (Preserved renal/hepatic clearance (C43.9)).

Common Symptoms & Clinical Signs

  • • Asymmetry - the shape of one half does not match the other
  • • Border - the edges are ragged, blurred or irregular
  • • Presentation of Melanoma (C43.9): unintended weight loss [Melanoma C43.9]
  • • Secondary Melanoma clinical sign: unexplained bleeding, chronic in Melanoma (C43.9: hoarseness/cough, or progressive)
