Stage 4 basal cell carcinoma is caused when earlier stages of basal cell carcinoma advance. Initially, 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 that build up over time and eventually form a tumor. When these tumors are left untreated, the cancerous cells begin to invade nearby tissue and eventually spread throughout the body. The most common way that the DNA is damaged is by a lot of sun exposure over the years, although other factors like exposure to toxic chemicals and certain genetic disorders may also lead to stage 4 basal cell carcinoma in some people.
