Cancer is a disease in which abnormal cells divide at an uncontrollable rate. These fast developing cells crowd normal cells and destroy body tissues. When this happens it makes it hard for your body to work the way it should. Cancer is not just one disease, but infact many different diseases that are alike in some way, but are different in the ways they grow and spread.
What Causes Cancer Cells Growth? To broadly explain it, there are three main things that cause the growth of cancerous cells. One is if something causes damage to your DNA. Another is if something were to stimulate your cells to divide at a fast rate. Lastly if something messed with the control rate in which your body produces cells like. Those are the three main things that promote or cause cancer growth. What are the Stages of Cancer? The initial term “stage of cancer” refers to what stage the cancer was at when it was first diagnosed. There are five different stages of cancer they go from zero to four. Stage Zero: Stage zero cancer is called in situ cancer. In situ cancer will usually form in one spot. In situ cancer poses little to no threat to life. Stage One: Stage one cancer is referred to as localised cancer. This is when the cancer remains in a single lump inbetween the tissues where it formed and neighboring tissues. This is considered a serious step in the cancer growth. In this stage the growth normally doesn’t threaten life. Stage Two and Three: Stage two and three fall hand in hand, these stages are called regional spread. In these stages cancer has spread within the region in which it formed, but not in any other body parts yet. Also in this stage, cancer can get caught in the lymph node, divide and form more cancer lumps. Stage Four: Stage four is known as distant spread. In stage four cancer cells from the cancer lumps may spread further through lymph vessels into more distant lymph nodes or into your bloodstream. Once cancer cells have made their way into your bloodstream they are free to move anywhere in your body, form new colonies, and spread further. |
