[|AI|]  Hi, Welcome to Chat Doctor, I have gone through your question and understand your concerns.  There are several factors (environmental- excessive smoking, alcohol intake, excessive sun exposure, fatty diet, dye exposure, industrial wastage). Hereditary-runs in families. Survival rate depends on the stage (stage 1- live longer, stage 4- less survival due to metastasis (other organs' involvement).  Early detection, early stage, early treatment - survival is good. Hope, I have answered your query. Wishing you good health.
