The cure for cancer is still some way off but it is something that science expects to happen possibly within the next few decades; although cancer rates have not dropped, the number of people that die from it have declined in recent years. I wonder if you can imagine a time when this disease is no longer a problem or when a visit to the doctor for some routine tests does not bring the fear that it does at the moment? The causes for cancer seem to be many but despite all the knowledge we gain, it is still almost impossible to know if or when a person will contract it.
If someone were to ask you what cancer was, would you be able to give them a definition like the one in this article? Well, it is a disease that's characterized by a large number of cells that continue to grow and divide; they invade and destroy adjacent tissues and may even spread to other anatomical sites through a process called metastasis.
The difference between a cancerous tumor an a benign one is that malignant tumors continue to grow whereas benign ones limit their growth an many of us live comfortably with them during out lives without even knowing. The risk of contracting this condition increases with age even though it can also affect the young; thirteen percent of people die from one of it's many strains every year around the world. Cancerous cells may have been transformed by radiation or poison for example and this creates genetic abnormality in those cells which then continue to grow and divide.
The cause can also be the responsibility of faulty DNA replication or a genetic trait inherited from parents which means a person can be born with them. Complex relationships between carcinogens and a person's genetic makeup may explain why only some develop it after exposure to a known carcinogen.
Long term research has given a better picture of what cancer is and the study of cancer is one of the top ten diseases being researched throughout the world. Much of the world's research into diseases is to try and find the reason why some people do not contract certain diseases whilst others do. By understanding the origins of cancer, perhaps we will be able to avoid contracting it until we come up with a cure.
Over recent years, concern has been made public over the possibility that our dietary habits may be partly to blame for the incidence of the condition. There are certain foods that are considered risky such as excess salt in the diet, too much saturated fat and overindulgence in dairy foods. In particular, excess calcium is believed to have a direct effect on the incidence of prostrate cancer amongst men around the world.
Cancer can strike anywhere in the body and each is a specialist type to the organ or part of the body it has infected. Some people can have cancer for several years before they have any symptoms and this does not help their chances of being cured. However, mortality rates from cancer are decreasing and although a cure may not be possible, there are treatments available to slow its spread. All this research is gradually leading towards more effective treatments for cancer and it is not always the terminal disease it used to be.
