Cancer continues to be one of the most serious diseases and the second leading cause of death around the globe: Each year more than 11 million people are diagnosed with some kind of tumor and over half of them die from cancer. The global cancer rates are increasing due to the aging population and longer life expectancy, as well as changes to the lifestyle of the developing world. The most common cancer types are currently colorectal cancer, lung cancer, prostate cancer and breast cancer. Not all cancer diseases are terminal. An early detected tumor can be treated effectively using chemotherapy, surgery or radiation therapy.
