Cancer and Oncology

Cells are the basic units of the human body. They grow and divide to make new cells for the growth and development of human body. These cells die when they get too old or damaged and in this process new cells take their place. But Cancer begins when genetic changes interfere with this process and cells start to grow uncontrollably. These cells may form a mass which is called as tumor. A tumor can be benign or cancerous. A cancerous tumor is malignant, which means it can grow and spread to other parts of the body, where a benign tumor means the tumor can grow but will not spread to the other parts. But some types of cancer do not form a tumor.

Cancer is a disease caused by the unusual division of cells and causes tissues destruction. It is not a single disease but it is the name given to a collection of more than hundred related diseases.

Oncology is the study of Cancer. It is the branch of medicine that specializes in prevention, diagnosis, and treatment of cancer. A doctor or medical professional that deals who practices oncology is an Oncologist.
