ALL YOU NEED TO KNOW ABOUT CANCER

 

Cancer can be referred to as any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer often has the ability to spread throughout your body. It is the second-leading cause of death in the world. But survival rates are improving for many types of cancer, thanks to God for the improvements in cancer screening and cancer treatment.

Causes of cancer

Cancer is caused by accumulated damage to genes. Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide. Errors in the instructions can cause the cell to stop its normal function and may allow a cell to become cancerous.
