Today, cancer constitutes a major health problem. In the United States, it is the second leading cause of death. Approximately one out of every two men and one out of every three women get cancer at some point during their lifetime. Furthermore, the risk of getting cancer has been further increasing due to the change in the habits of people in our century such as the increase in tobacco use, deterioration of dietary habits, and lack of activity.
Fortunately, the recent advances in medicine and technology have significantly increased the possibility of curing cancer. However, the chance of curing cancer primarily relies on its early diagnosis and the selection of its treatment depends on its growth level.
