      Venous thromboembolism (VTE) is a major common complication in cancer patients. Risk-adapted thromboprophylaxis and antithrombotic therapy for patients diagnosed with VTE can reduce the recurrence of VTE events. Thrombotic risk varies according to cancer type, stage, and comorbidities. The current review analyzes most recent data and provides clinical guidance for the management of women with cancer-associated thrombosis.
