National Cancer Week, which is held every year between 1 and 7 April, was announced in our country to raise public awareness about cancer. Thus, increasing public awareness about; screening methods, correct lifestyle, diagnosis, and treatment possibilities.

Cancer, one of the most common diseases of modern times, is a disease in which certain cells divide uncontrollably and spread to other parts of the body. (one). The two main characteristics of cancer cells are uncontrolled cell division and the ability to invade other tissues. Genetic and epigenetic changes play an essential role in these processes. (2-4)

Patients diagnosed with cancer are increasing day by day around the world. In industrialized countries, the number of patients diagnosed at some point in their lives is much more severe (5). According to the 2020 data of the World Health Organization, 20 million new cancer cases were diagnosed annually on a global basis, while 10 million deaths occurred due to the disease. Approximately 162 thousand people in Turkey are diagnosed with cancer annually (6). The most common cancers in 2020 are breast, lung, colon and rectum, prostate, skin, and stomach cancers (7).

Due to the lack of awareness among the public about cancer, the interest in screening methods is not at the desired level. The late manifestations of some types of cancer due to their course adversely affect the chance of treatment. Current cancer treatments include surgery, radiation, and chemotherapeutic drugs. The development of molecular methods in recent years has helped to apply the right targeted therapies by better defining the diagnosis and prognosis of patients (8-9).
