Minor trauma can cause the area to bleed. Other presentations include one which appears as a rough, red patch. They can be mistaken as pimples or rashes. The bloodstream is not invaded by basal cell carcinoma except in extreme cases. It can destroy and deform the area if it is not treated. The second most common form of skin cancer, squamous-cell carcinoma is also the second most prevalent. The outermost layer of skin is affected. The most common places for squamous-cell carcinoma to occur are the arms and face. In sun-exposed skin, it can appear as a bump or opaque patch. It may also be confused with a wart. Squamous cells can spread to the blood and lymph nodes, and even threaten a person's life. It is most common with large and aggressive squamous cells carcinomas, cancers of the upper head, lips, genitals, ears or skin that has been previously treated. Overall, the chance that a squamous-cell carcinoma will spread outside of the local area is 2%. However, this number can rise depending on where the cancerous tissue or features are located.
