There have been many improvements in our understanding of cancer. However, we still have not figured out the exact causes of cancer. Although we understand the basic mechanism in which the disease operates, there are many pieces of the puzzle that need to be solved. Some scientists think that cancer may be caused by a specific cocktail of environmental factors, genetics and cell mutations in combination with an individual's unique makeup. The increase in sophisticated treatments includes immunotherapy which focuses on harnessing the immune system from within to fight the disease. Chemoimmunotherapy attaches chemotherapy drugs to antibodies that are specific for cancer cells.
