Discover the key symptoms and causes of squamous cell skin cancer. Learn how sun exposure and DNA errors contribute to this common skin condition, and understand the importance of early detection and treatment to prevent serious health risks.
Understanding the Signs and Causes of Squamous Cell Skin Cancer
Squamous cell carcinoma is a prevalent type of skin cancer originating from the squamous cells forming the outer and middle skin layers. Typically considered less dangerous by medical professionals, this cancer can still pose serious health risks if not addressed early. Without treatment, it may grow substantially or spread, leading to severe health issues characteristic of advanced cancers.
Indicators of Squamous Cell Carcinoma
- A firm, red bump on the skin
- A sore that is flat, scaly, and crusted
- A new sore or recurring raised area on a scar or ulcer
- A rough, scaly patch on the lip that may turn into an open ulcer
- A red or rough patch inside the mouth that may itch
Origins of Squamous Cell Carcinoma
Normally, new skin cells replace old ones, pushing them towards the surface, where they die and shed. When DNA errors occur, this process malfunctions, causing uncontrolled cell growth that results in cancer.
Contributors like UV Radiation and Other Factors
Ultraviolet (UV) rays from sunlight or artificial sources such as tanning lamps can damage skin cell DNA. Interestingly, skin cancers may also develop in areas not commonly exposed to sunlight, suggesting other risk factors may contribute.
While less aggressive than other cancers, squamous cell carcinoma requires prompt medical attention upon noticing symptoms. Early diagnosis and treatment are vital to prevent serious health consequences.
