What is Cancer?

Cancer is defined as the uncontrolled cell growth of abnormal tissues or cells that might happen anywhere in the body. The group of abnormal cells is referred to as “cancer cells.” These also go by the names like tumor cells or malignant cells. The cancer cells are able to infiltrate the surrounding normal body cells & tissues. 

Frequently, it has been observed that cancer or tumor cells might break from the original mass of cells or tissue, travel across the lymph & blood systems, and find a home in other organs wherein they continue with the uncontrolled cellular growth. The process of the tumor cells leaving the source or origin and growing exponentially in other body parts or organs is referred to as “metastasis.”

Some of the causes of cancer are still unknown while other forms of cancer might be triggered due to lifestyle or environmental changes. Cancer might also develop due to more than one cause. 

Here is a listing of the major causes of cancer as per the research advances:
