Late detection of diseases is one of the reasons complicating the treatment process. For example, according to WHO, about 9 million people die of cancer each year. The main problem is that many cases of cancer are diagnosed too late. Even in countries with optimal health systems and services, many cases are detected late, when treatment success is more difficult.
This problem has to be faced not only in cases of diagnosing cancerous tumors, but also in a number of other tasks, such as: detection of pneumonia, various skin diseases, and others.
Often the diagnosis of these diseases is done on the basis of visual analysis.
