Today, oncological diseases are a leading cause of death. Experts in medicine, chemistry and biology are hard at work developing medications and treatment methods. The fight against cancer is made difficult by the fact that it’s not just an illness with specific symptoms and causes. Oncological diseases are caused by DNA mutations that lead to malfunctions of various systems inside people’s bodies. Essentially, a specific set of mutations represents a separate disease that needs to be tackled. Personalized treatment is considered the most promising approach: a specific set of medications aimed at preventing tumor growth is developed for each patient.
