Over twenty different types of cancer have been found to exist in the world today. Cancer kills over thousands of people in the United States alone every year. The news constantly contains reports of the many different types of ways a human can get cancer. The main reasons one can get cancer are smoking, dietary factors, exercise, occupation, genetics, pollution, radiation, and even prescription drugs. Out of all the main causes of cancer obesity and smoking are the leading causes. Cancer affects a person when abnormal cells within a tissue of a certain part of the human body continue to divide out of control. Normal cells stop reproducing after about fifty cycles. Since many types of cancer exist, anyone at any age has a risk of being diagnosed.
In an effort for people to speed up the process of finding a cure for cancer, people came up with urban legends and myths to preventing or getting rid of cancer. In the spring of 1999 many people began to believe that antiperspirants could cause cancer. The Canola oil, which is said to by scientists to be one of the healthier food oils, was also once rumored to be toxic and cancer causing.

One may wonder if cancer is a disease that travels through a family because of genes. The answer is that cancer will be more likely to occur in those who have close family members who have also had cancer. Breast and Ovarian cancer are the cancers that are most likely to be hereditary. A person can be tested to see if they are likely to inherit cancerous cells from a family member. Genetics are very important because they play a roll in finding a cure for cancer. Currently, scientists are trying to find and learn about the sequences of genes of types of cancer. Finding a pattern is important because later scientists will be able to change this pattern and prevent cancer that is hereditary. The main goal of scientists now is to discover a genome map, which is the body's materials list. These are the direct instructions to each human body. It is similar to a blueprint. Scientists are very excited because the first working draft of the human genome has been completed. Scientists are able to research these cures through a lot of time, complicate machinery and extensive research of the human body.
Today cancer is affecting more people than it ever has before. Scientists hope to make many advances in the future. Doctors ho
