The cancer is a neoplastic disease, which converts the c élulas of the body in carcinomas that at a given time will become malignant tumors. It is said that a person has Cancer when the affected cells begin to cause significant changes in human metabolism, causing symptoms closely related to the direct deterioration of the organism. All this concludes in the invasion of neighboring tissues and the spread of cancer throughout the body until metastasis is created, which is when cells of another type are also affected by carcinomas.
Cancer disease is the cause of the death of more than 13% of the world's population per year. The causes of cancer are unknown, basically, they are due to the lack of care of the body, poor diet is one of the causes, but the most common for which millions of campaigns have been made to combat it is the use of smoking.
