According to the World Health Organization, early cancer detection and screening are essential components of a comprehensive cancer control response. Early diagnosis is targeted at people with pre-existing symptoms and signs of cancer. Its goal is to detect the disease as early as possible, quickly make an accurate diagnosis and start the right treatment. Cancer screening is the search for a malignant neoplasm in a person who does not have any symptoms of a tumor. Such tests in some cases help to detect diseases at an early stage, when many types of cancer can be completely cured. Remember! Timely detected disease is the key to successful treatment!
