Basal cell carcinomas are the most common type of skin cancer. They appear as red patches or growths, and rarely spread. Because basal cell carcinomas can often resemble other skin conditions, such as eczema or psoriasis, it is important to seek the opinion of a dermatologist as soon as the abnormality is noticed.
Basal cell carcinoma is the least dangerous form of skin cancer, however if not treated in a timely manner, some sores could leave damaging scars. While other types of skin cancer may have a variety of causes, basal cell carcinoma is a direct result of harmful ultraviolet (UV) ray exposure, found in sunlight and tanning beds. You can eliminate the risk of developing basal cell carcinoma by wearing protective clothing, avoiding tanning beds, and applying a broad-spectrum sunblock with an SPF of at least 70.
