Causes of Oral Cancer

What are the causes of Oral Cancer?

Oral cancers can grow or occur when the cells in the lips and mouth get mutated. The mutation occurs in their DNA. The DNA of a cell contains valuable information about the work process of that cell as well as the replication cycle. With the mutation in the picture, the cell continues replicating itself even when not required. It slowly depletes the healthy cells, and those healthy cells are, over time, replaced by the tumorous cells.

These tumorous cells later form cancer and can spread throughout the body in the later stages. Oral cancers usually begin to grow from the thin, flat cells called squamous cells that form the lips and inside of the mouth. Most of the oral cancers are squamous cell carcinomas. The actual cause of the mutation occurring in the cell has not been identified yet.
