The Right Mix: Antihypertensives Can Decrease Drug-Induced Lung Injury in Cancer Therapy

Scientists reveal that high blood pressure increases lung damage risk in patients with cancer who receive bleomycin chemotherapy. Bleomycin is a drug used to treat certain cancers, such as Hodgkin lymphoma and germ cell tumors. But, bleomycin chemotherapy can cause near-fatal lung damage, a condition called bleomycin-induced lung injury. Now, […]
