Stage 0 basal cell carcinoma is caused by problems with certain skin cells. Normally, DNA controls the growth cycle of cells in the skin, causing new cells to replace older cells at a regular pace. However, when the DNA is damaged, it causes an overgrowth of skin cells. These cells build up over time and eventually form a tumor. The most common way that the DNA is damaged is by excessive sun exposure, although other factors like exposure to toxic chemicals and certain genetic disorders may also cause basal cell carcinoma in some people.
