When cells continue to multiply which the body do not need, it results to a mass, or growth which is called tumor that could either be malignant or benign. The malignant tumor is the one that is cancerous while the malignant tumor is non-cancerous. (Fayed, 2006).
Several changes occur in the body before a cancer develops Mayoclinic.com enumerates such changes as follows: (1) an initiator to cause a genetic mutation sometimes caused by forces within the body, such as hormones, viruses and chronic inflammation; or forces outside of the body, such as ultraviolet (UV) light from the sun or cancer-causing chemicals (carcinogens) in the environment; (2) a promoter to cause rapid cell growth which could lead to a tumor. The promoters could be inherited, could come from inside or outside the body; and (3) a progressor to cause cancer to become aggressive and spread.
There are many facts about cancer. Fayed in an article enumerated the facts that: (1) one in three people will develop cancer; (2) one in four people will die of cancer; (3) in 2005, about 1.4 million new cases of cancer were diagnosed; (4) more than 1500 Americans died each day of cancer this year; (5) over 1,000,000 cases of skin cancer will be diagnosed this year; (6) cancer is the leading cause of death among Americans under the age of 85.
Considering such facts, it is important therefore to have a comprehensive understanding of what the disease is all about, and to find out the extent of damage it can cause to a person in order to be enlightened on what it should be done to help in the prevention and possible treatment of the disease. This paper then shall investigate on cancer, its types, its risk factors and causes, and its treatment. Specifically it aims to enlighten the general public why it is considered a disease of the old.
Before discussing the several factors that causes cancers it is imperative to be cleared on some important information that confused many people about cancer. The US National Health Institute thinks that it is important for all to keep in their mind the following;
Not everything causes cancer.
Cancer is not caused by an injury, such as a bump or bruise.
Cancer is not contagious. Although being infected with certain viruses or bacteria may increase the risk of some types of cancer, no one can "catch" cancer from another person.
Having one or more risk factors does not mean that you will get cancer. Most people who have risk factors never develop cancer.
Some people are more sensitive than others to the known risk factors.
As to the risks factors of cancer the MedicineNet.com presented the following: (1) growing older (2) tobacco, (3) sunlight; (4) ionization radiation; (5) certain chemicals and other substances; (6) some viruses or bacteria, (7) family history of cancer; (8), alcohol, (9) poor diet, (10) lack of physical activity; or (11) overweight.
It is most likely that a person who is aging and growing older has higher risk of cancer. In a study about yeast, scientists at Fred Hutchinson Cancer Research Center found out that aging is a potent carcinogen. Gottschilling (as cited by TodaySeniorNetwork, 2003) states:
While yeasts don't get cancer, they do have one of the major hallmarks of malignancy, which is genetic instability, we
