Every year, “World Cancer Day” is celebrated on 4 February, to increase awareness of cancer and the techniques for prevention and treatment. Chemotherapy has been used as a main treatment for years. It uses drugs to kill fast-growing cancer cells, but also damages healthy cells, like those of skin, hair and intestine. These damages may cause side effects.
Scientists try to approach new methods to minimize negative effects. Among various methods, “Targeted Cancer Therapy” has been extremely efficient for many types of cancer. Targeted therapies are drugs designed to block specific molecules, such as proteins or genes, that help cancer cells grow and spread. This way, the normal cells are survived. The development of targeted therapy drugs has led to encouraging survival rates.
