At Fall Creek Skin and Health Clinic, we believe that understanding health conditions is the first step toward prevention and treatment. Skin cancer is one of the most common forms of cancer today, yet many people are unsure about how it develops. In this comprehensive guide, we’ll explore the formation of skin cancer, the types of skin cancer, and how you can protect yourself.
Skin cancer primarily occurs when the DNA of skin cells becomes damaged, usually due to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. This damage leads to mutations that affect how skin cells grow and divide. Under normal circumstances, the body regulates cell growth and repairs damaged DNA. However, when the damage is extensive or the repair mechanisms fail, mutated cells begin to proliferate uncontrollably, forming a tumor.
The development of skin cancer can be categorized into three main types:
This is the most common type of skin cancer, typically arising in the basal cells found in the outer layer of the skin. BCC usually develops on sun-exposed areas such as the face, neck, and arms. It grows slowly and is less likely to spread than other forms of skin cancer.
This type develops in the squamous cells, which make up the middle layer of the skin. Like BCC, SCC commonly occurs in areas exposed to the sun. It can grow larger and may spread to other parts of the body if not treated.
Melanoma is the most aggressive form of skin cancer. It develops in the melanocytes, the cells responsible for producing melanin—the pigment that gives skin its color. Although melanoma accounts for a smaller percentage of skin cancer cases, it is responsible for the majority of skin cancer deaths. Early detection and treatment are critical for improving outcomes.
Several factors increase the likelihood of developing skin cancer:
Prolonged exposure to UV rays from the sun or tanning beds dramatically increases the risk of skin cancer.
Individuals with fair skin, light hair, and blue or green eyes are at a higher risk.
A family history of skin cancer can indicate a genetic predisposition.
Older individuals are more prone to skin cancer due to cumulative sun exposure over the years.
Conditions or medications that weaken the immune system can elevate the risk of skin cancer.
While not all skin cancers can be prevented, there are several steps you can take to reduce your risk:
Apply broad-spectrum sunscreen with an SPF of at least 30 daily, even on cloudy days.
Avoid direct sun exposure, especially during peak hours (10 a.m. to 4 p.m.).
Long sleeves, hats, and sunglasses can shield the skin from harmful UV rays.
Conduct self-examinations and schedule regular check-ups with a dermatologist to catch any suspicious changes early.
