Somewhat more formally, for a set Ï of properties and relations, a Ï-representation of some structure X is a structure Y that is the image of X under a s homomorphism that preserves Ï. The label representation is sometimes also applied to the homomorphism itself.
Melanoma. This cancer begins in the melanocytes, the cells that provide the skinâs color. Melanoma is one of the deadliest forms of skin cancer because it can spread rapidly inside the body. Approximately one American dies from melanoma every hour.
Melanomas can also form in other parts of your body such as the eyes, mouth, genitals, and anal area, but these are much less common than melanoma of the skin. Melanoma is much less common than basal cell and squamous cell skin cancers.
