Understanding the Different Types of Skin Cancer

Written By Chasadea Potter

Understanding the different types of skin cancer can help you recognize warning signs and seek treatment early. While all forms of skin cancer involve abnormal skin cell growth, their behavior, appearance, and risk factors vary.

Basal Cell Carcinoma (BCC)

The most common skin cancer. It typically appears as:

  • A pearly or shiny bump

  • A persistent sore that doesn’t heal

  • A pink patch that may crust or bleed

BCC grows slowly and rarely spreads, but if left untreated, it can cause significant local tissue damage.

Squamous Cell Carcinoma (SCC)

SCC is the second most common type. Look for:

  • Scaly, red patches

  • Firm bumps

  • Crusted or bleeding lesions

SCC can grow faster than BCC and has a slightly higher risk of spreading if untreated.

Melanoma

The most serious type of skin cancer. Melanoma can appear as a new dark spot or develop from an existing mole. Early detection is crucial because melanoma can spread rapidly.

Use the ABCDE rule to evaluate moles and spots:

  • Asymmetry

  • Border irregularity

  • Color variation

  • Diameter >6mm

  • Evolving

    There are additional, less common types of skin cancer beyond these three. However, basal cell carcinoma, squamous cell carcinoma, and melanoma make up the vast majority of diagnoses.

Recognizing the differences between these types can save lives. Professional skin exams complement self-checks and help detect dangerous lesions early.
