As we reach peak summer temperature, we all relish the opportunity to soak up the sun and enjoy the great outdoors. However, with increased sun exposure comes the heightened risk of skin cancer, a concern that cannot be taken lightly. Understanding the dangers of skin cancer and how it develops at the cellular level is crucial in taking preventive measures.
Skin cancer is one of the most common types of cancer in the United States and worldwide. According to the American Academy of Dermatology (AAD), one in five Americans will develop skin cancer in their lifetime. Each year, more than 5 million cases of skin cancer are diagnosed in the U.S. alone. The three main types of skin cancer—basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma—vary in prevalence and severity:
-
Basal Cell Carcinoma (BCC): The most common form of skin cancer, accounting for approximately 80% of all cases. BCC is usually slow-growing and rarely spreads but can cause significant tissue damage if left untreated.
-
Squamous Cell Carcinoma (SCC): The second most common type, representing about 20% of cases. SCC can be more aggressive than BCC and has a higher risk of spreading to other parts of the body if not treated promptly.
- Melanoma: Although less common, melanoma is the most dangerous form of skin cancer. It accounts for about 1% of all skin cancer cases but is responsible for the majority of skin cancer deaths due to its high potential to spread
Understanding Skin Cancer
at the Cellular Level
at the Cellular Level
Skin cancer begins when the DNA in skin cells becomes damaged, often due to ultraviolet (UV) radiation from the sun or tanning beds. This damage can cause mutations in the genes that control cell growth and division, leading to uncontrolled cell proliferation. The primary types of skin cancer include:
Skin cancer begins when the DNA in skin cells becomes damaged, often due to ultraviolet (UV) radiation from the sun or tanning beds. This damage can cause mutations in the genes that control cell growth and division, leading to uncontrolled cell proliferation. The primary types of skin cancer include:
The damage to skin cells from UV radiation can cause oxidative stress, leading to an imbalance between free radicals and antioxidants in the body. This oxidative stress can further exacerbate cellular damage and contribute to the development of skin cancer.
1. Basal Cell Carcinoma (BCC):
Originating in the basal cells, which produce new skin cells as old ones die off. BCC often appears as a pearly bump or a flesh-colored mole.
2. Squamous Cell Carcinoma (SCC):
Arising from the squamous cells that make up the middle and outer layers of the skin. SCC may look like a red, scaly patch or a sore that doesn’t heal.
3. Melanoma:
Developing in the melanocytes, the cells responsible for producing pigment. Melanoma is the most dangerous form of skin cancer and often resembles a mole that changes shape, color, or size.

How Skin Cancer Develops
Basal Cell Carcinoma (BCC):
- Cellular Origin: BCC originates in the basal cells, which are located in the lower part of the epidermis. These cells produce new skin cells as old ones die off.
- Development: When DNA in basal cells is damaged by UV radiation, mutations can occur. These mutations disrupt the normal cell cycle, leading to uncontrolled growth and the formation of cancerous lesions.
- Appearance: BCC typically appears as pearly or waxy bumps, often with visible blood vessels. It can also manifest as flat, flesh-colored or brown scar-like lesions.
- Danger: Although BCC rarely spreads (metastasizes) to other parts of the body, it can cause significant damage by growing and invading surrounding tissues, including nerves and bones.
Squamous Cell Carcinoma (SCC)
- Cellular Origin: SCC begins in the squamous cells, which are found in the middle and outer layers of the skin.
- Development: Similar to BCC, SCC develops when UV radiation causes DNA damage in squamous cells. The mutations lead to abnormal cell growth and the development of cancerous tumors.
- Appearance: SCC often appears as red, scaly patches, open sores, or wart-like growths that may crust or bleed. These lesions can occur on sun-exposed areas like the face, ears, neck, and hands.
- Danger: SCC is more likely than BCC to spread to other parts of the body, including lymph nodes and internal organs, making it potentially more dangerous if not treated promptly.
Melanoma
- Cellular Origin: Melanoma originates in melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color.
- Development: UV radiation can cause mutations in the DNA of melanocytes, leading to uncontrolled cell division and tumor formation. Melanoma can develop in existing moles or appear as new, unusual-looking growths.
- Appearance: Melanomas often resemble moles but with asymmetrical shapes, irregular borders, multiple colors, and a diameter larger than a pencil eraser. They can also change in size, shape, or color over time.
- Danger: Melanoma is the most dangerous form of skin cancer because it is more likely to spread (metastasize) to other parts of the body, including the lymphatic system and internal organs, making early detection and treatment critical.
How Skin Cancer Spreads and Its Impact
METASTASIS: THE SPREAD OF CANCER
Metastasis is the process by which cancer cells spread from the primary site (where the cancer started) to other parts of the body. This occurs in several stages:
- Local Invasion: Cancer cells invade nearby normal tissue.
- Intravasation: Cancer cells enter the bloodstream or lymphatic system.
- Circulation: Cancer cells travel through the bloodstream or lymphatic system to other parts of the body.
- Extravasation: Cancer cells exit the bloodstream or lymphatic system and invade new tissues.
- Proliferation: Cancer cells grow and form new tumors at the secondary site.
IMPACT ON ORGANS AND CELL FUNCTION
Once skin cancer spreads, it can affect various organs and disrupt their normal function. The impact depends on where the cancer has metastasized:
- Lymph Nodes: Cancer in the lymph nodes can impair the immune system’s ability to fight infections.
- Liver: Metastasis to the liver can lead to liver dysfunction, impacting detoxification and metabolism.
- Lungs: Cancer in the lungs can cause respiratory issues and reduce oxygen supply to the body.
- Brain: Metastasis to the brain can cause neurological symptoms, such as headaches, seizures, and cognitive changes.
Cancer cells can disrupt normal cell function by competing for nutrients and space, leading to organ failure and other serious complications. This makes advanced skin cancer extremely dangerous and underscores the importance of early detection and treatment.
Symptoms of Skin Cancer
- New growths or sores that don't heal
- Changes in existing moles: Asymmetry, irregular borders, multiple colors, or changes in size
- Red, scaly patches: Often on sun-exposed areas
- Waxy or pearly bumps: Particularly for BCC
- Sores that bleed or crust: Common in SCC
Treatments for Skin Cancer
- Surgical Excision: Removing the cancerous tissue and some surrounding healthy tissue.
- Mohs Surgery: A precise surgical technique used primarily for BCC and SCC, where layers of cancer-containing skin are progressively removed and examined until only cancer-free tissue remains.
- Cryotherapy: Using extreme cold to destroy cancerous cells, often used for superficial skin cancers.
- Radiation Therapy: Using high-energy radiation to kill cancer cells, typically used when surgery is not an option.
- Chemotherapy: Topical or systemic drugs to kill cancer cells, generally used for more advanced cases.
- Targeted Therapy: Drugs that target specific genetic mutations within cancer cells, commonly used for melanoma.
