Skin Cancer 101: Types, Causes, and Risk Factors

Skin cancer is the most common type of cancer, but with early detection and prevention measures, it is also one of the most preventable and treatable forms of cancer. To protect yourself and your loved ones, it's essential to understand the basics of skin cancer, including its types, causes, and risk factors. Dr. Heather Layher at Idaho Dermatology Mohs Collective in Boise, ID, can explain what to know about skin cancer.

Understanding the Basics of Skin Cancer

There are different types of skin cancer that you might deal with, and it’s important to understand each one and how it could manifest in your body. The sooner you recognize signs of skin cancer, the easier it is for your dermatologist in Boise, ID, to treat. The three types of skin cancer include:

• Basal Cell Carcinoma (BCC) is the most common type of skin cancer. It typically appears as a small, shiny bump or pinkish patch on the skin. It often develops on skin areas frequently exposed to the sun, such as the face, scalp, ears, and neck.
• Squamous Cell Carcinoma (SCC) is the second most common type of skin cancer. It usually presents as a red, scaly patch or a firm, raised bump. Like BCC, this form often occurs on sun-exposed areas of the skin but can also develop on scars, sores, or chronic skin conditions.
• Melanoma: Melanoma is less common but more aggressive than BCC and SCC. It typically appears as a dark, irregularly shaped mole or lesion, but it can also develop from existing moles or appear as new growths on the skin. If left untreated, melanoma has the potential to spread to other parts of the body, making early detection crucial.

The primary cause of skin cancer is exposure to ultraviolet (UV) radiation from the sun or tanning beds. UV radiation damages the DNA in skin cells, leading to mutations that can trigger the development of skin cancer over time.

Common risk factors for skin cancer include:

• Sun exposure without protection
• Fair skin
• History of freckles or sunburn
• Family history of skin cancer
• Personal history of skin cancer
