If ovarian cancer has lymphatic metastasis, it means it has reached advanced stage. The survival period of advanced stage ovarian cancer is relatively short, but if treated actively, it can prolong the life of patients and the 5-year survival rate can reach 20%-40%, but the prognosis is relatively poor. However, if ovarian cancer is detected at an early stage and treated with surgery, the prognosis is better and the 5-year survival rate can reach 70%-90%. Ovarian cancer is a kind of malignant tumor that seriously threatens women’s health and has a very high mortality rate. In the late stage, because cancer cells spread easily and very fast, the main reason for death of patients with late stage ovarian cancer is that their bodies cannot accept the encroachment of cancer cells and therefore their lives are in danger.
