Thank you for the opportunity to help you with your question!
Cancer is caused by mutations in your cells (which can be caused by any number of things, including radiation, carcinogens, and genetics ). These cells are flawed in such a way that they reproduce uncontrollably, ignoring your body's natural blueprint, forming tumors. These cells interfere with your bodily functions and will even attack good cells, eventually killing you.
some cancers with causes.................
excessive exposure to ultraviolet radiation is the most frequent cause of basal cell carcinomas.
the most common cause of lung cancer is long-term exposure to tobacco smoke.
human papillomavirus infection is the most frequent cause of cervical cancer.
