Skin Cancer
Skin cancer is one of the most common types of cancer, affecting millions of people worldwide. It occurs when skin cells grow abnormally, often due to damage from ultraviolet (UV) radiation caused by sun exposure, tanning beds, or other factors such as radiation therapy or contact with harmful substances. There are several types of skins cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma, each with unique characteristics and varying levels of severity.
While anyone can develop skin cancer, certain factors can increase the risk:
-
Sun exposure
-
Use of tanning beds
-
Exposure to radiation/radiation therapy
-
Fair skin
-
Family history and genetics
-
Risk increases as age increases
-
Weakened immune system
-
Pregnancy in women

Basal Cell Carcinoma
Basal cell carcinoma is the most common type of skin cancer. It often develops in areas exposed to the sun, like the face and neck.
It usually appears red or pink in color as a pearly or waxy bump, a flat lesion with a raised edge, or a scar-like lesion.
Basal cell carcinoma rarely spreads to other parts of the body but can grow deeply, potentially causing damage to nearby tissue.

Squamous Cell Carcinoma
Squamous cell carcinoma is the second most common type of skin cancer, often occurring on sun-exposed areas, such as the ears, face, and hands.
It often presents as a firm red nodule, a scaly lesion, or a sore that heals and reopens. Squamous cell carcinoma can spread to nearby tissues and, in some cases, other body parts, underscoring the importance of early detection and treatment.
Factors such as prolong sun exposure and a family history of squamous cell carcinoma can increase your risk.

Melanoma
Melanoma is the most dangerous type of skin cancer, capable of developing anywhere on the body, even in areas not exposed to the sun.
It often begins as a mole that changes in size, color, or shape and may appear as a black or brown spot with irregular edges.
Melanoma can spread quickly to other organs, making it the deadliest form of skin cancer if not detected and treated early.
A family history of melanoma is a factor in 7-15% of cases, so it is essential to ask direct family members about any history of this condition. Early awareness and proactive measures can be lifesaving.
Understanding the Risk Factors

The Importance of Prevention and Early Detection
Prevention through sun protection, regular skin checks, and dermatologist visits is crucial. Most skin cancers are highly treatable, especially when detected early, making routine monitoring essential for long-term skin health.
