Which risk increases as platelet counts markedly drop during chemotherapy?

💡 Explanation

A sharp decline in platelet counts causes an increased risk of spontaneous hemorrhage, due to thrombocytopenia. Because the blood coagulation cascade cannot properly initiate with insufficient platelets, therefore even minor injuries can lead to severe bleeding, rather than controlled hemostasis.
