There is no single visual feature that defines all skin cancers, but there are patterns to be aware of. By becoming familiar with the natural appearance of your skin and regularly checking for changes in moles, freckles, and other skin features, you can increase your chances of catching warning signs early.
Three Common Types of Skin Cancer
There are several types of skin cancer, but the three most commonly diagnosed are:
Basal Cell Carcinoma (BCC)
Squamous Cell Carcinoma (SCC)
Melanoma
Each presents with unique characteristics. Let’s break down what to look for and when to see a healthcare professional.
Common Features:
Appears most often on sun-exposed areas: face, ears, neck, and shoulders.
Often looks like a pearly or translucent bump, sometimes with visible blood vessels.
Can also present as a flat, scaly patch or a sore that won’t heal or keeps returning.
May bleed, crust, or appear shiny and raised.
Important: While BCC is slow-growing and rarely spreads, delayed treatment can lead to local tissue damage. Always consult a healthcare provider if you notice a suspicious lesion.

Common Features:
Most often develops on sun-exposed areas such as the face, scalp, ears, and hands.
Presents as a thick, scaly, or crusty lesion, or a rapidly growing red nodule.
May bleed, itch, or become tender to the touch.
Can spread to nearby tissues or lymph nodes if left untreated.
SCC is more likely to affect individuals over 50 and those with fair skin. According to the CDC, prompt diagnosis and treatment offer excellent outcomes.
Key Warning Signs:
May appear as a new mole or a change in an existing mole.
Often has irregular borders, asymmetry, and multiple colors (brown, black, blue, red, or white).
Can develop on any area of the body, including areas not frequently exposed to sunlight.
Can be flat or raised, and sometimes feels itchy or bleeds.
