Skin Cancer Types and ABCDE Rule

These flashcards cover types of skin cancer and the ABCDE rule for identifying concerning skin lesions.

Squamous Cell Carcinoma

A type of skin cancer that affects the epidermis, characterized by red inflammation and uncontrollable division of cancer cells.

Basal Cell Carcinoma

The least malignant skin cancer primarily affecting the stratum basale of the epidermis.

Melanoma

A highly malignant skin cancer arising from melanocytes, often diagnosed using the ABCDE rule.

ABCDE Rule

A method for evaluating skin lesions based on Asymmetry, Border, Color, Diameter, and Evolving characteristics.

Asymmetry (A)

If one half of the mole or spot is unlike the other half, it may indicate melanoma.

Border (B)

When the spot has irregular, scalloped, or poorly defined borders, it could be a sign of melanoma.

Color (C)

A mole with varying colors from one area to another, including shades of tan, brown, black, red, or blue, is concerning.

Diameter (D)

A mole larger than 6 millimeters (about the size of a pencil eraser) is more likely to be melanoma.

Evolving (E)

If a mole looks different from the rest or is changing in size, shape, or color, it may signal melanoma.
