How Does Cancer Occur?

Cancer occurs when the cells of a certain part of the body start growing in number at a faster rate, due to several unknown reasons. Later on those growing cells take an odd shape and encumber that part of the body to which they belong from performing its normal functions.

Nevertheless cancer is not incurable anymore. Advancements in technology have enabled medical science to help a person get rid of the disease on a convenient basis. However there are some restraints to this solution. The first and foremost is the stage of cancer that the patient is enduring. If the person is at an early stage, the cancer lump could be removed by surgery or killed by treatment of X-rays or gamma rays. Otherwise the growing number of cells start spreading through the entire body and start creating trouble in other parts of the body too, resulting in serious consequences.

Cancer can be any malignant growth or tumour caused by abnormal and uncontrolled cell division. It may spread to other parts of the body through the lymphatic system or the blood stream. Cancer refers to any one of a great number of diseases characterized by the growth and development of the abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissues. Cancer has an ability to spread throughout your body. Being diagnosed with cancer can be scary.

But a thoughtful understanding about what's going on inside your body can aid you feel more in control of your disease. Cancer starts with the damage (mutations) in your DNA. Your DNA is just like a set of instructions for your cells, telling them how to grow, nurture and divide. The normal cells mostly develop mutations in their DNA, but they have an aptitude to repair most of these mutations. Or, if they can't make the maintenance and repairs, the cells can often die. Though, certain mutations aren't repaired, causing the cells to breed and become cancerous. Mutations also cause the cancer cells to live beyond a normal cell life span. This causes the cancerous cells to build up.
