Ovarian cancer is the seventh most common cancer among women in the world. It accounts for only 4% of all cancers in women, but the devastating information is that it is the deadliest of all gynecological tumors. The reason for this is its late detection in an already advanced stage when treatment options are already very limited. The cause of ovarian cancer is unknown. Among the factors that have an impact on development, the following are important: age, the occurrence of cancer in the family, the reproductive function of a woman, and environmental factors. The symptoms of ovarian cancer are non-specific and often go unrecognized, even though they appear even in the early stages of the disease. Because of this, a large number of cases, even 70%, are discovered when cancer has already spread.
