Many of the deadliest cancers receive the least amount of research funding Posted: 18 Jul 2019 01:48 PM PDT Many of the deadliest or most common cancers get the least amount of nonprofit research funding, reports a new study. 'Embarrassing' or stigmatized cancers, like lung and liver, are underfunded. Colon, endometrial, liver and bile duct, cervical, ovarian, pancreatic and lung cancers were all poorly funded compared to how common they are and how many deaths they cause, the study found. In contrast, breast cancer, leukemia, lymphoma and pediatric cancers were all well-funded, respective to their impact on society. |
