Cancer

Cancer is a disease of the genes. It can also be defined as a group of diseases that are categorized by uncontrolled growth of the cells in the human. Cancer also has the ability to make these uncontrolled growths of cells travel from the original site to other parts of the body. The genes are a small part of DNA, which on the other hand, are the master molecules of the cell. The genes are the ones responsible for making proteins in the body which serves as workhorses of the body’s cells. The proteins made by the genes permit the body carry out all of the many processes, for instance, thinking, moving and breathing. As an individual grows, the cells in one’s body grow, divide and replace themselves. A lot of genes produce protein that plays a vital role in controlling the processes of cell growth and cell division. The disruption caused by alteration or disruptions on the DNA molecule can cause the genes to produce faulty proteins. When this happens, the cells become abnormal and the cells also get to lose the restraints on its growth. This is when the abnormal cells start to divide rapidly and uncontrollably. The growth that the abnormal cells form is called tumor. Not all tumors are cancerous. Tumors can either be benign or malignant. The cancerous tumors are the one that spreads out to any part of the body. Cancerous tumors are called malignancies. Cancer can occur to anyone and at times, can also be inherited. Certain behaviors and environmental risk factors are also known to cause cancer. Both nutrition and diet play a significant role in preventing and treating cancer.
