Northwestern Medicine Study Uncovers Mechanism for Accelerated Tumor Growth Post-Immunotherapy

A new study from Northwestern Medicine, published in *Cancer Discovery*, has identified a biological mechanism that may explain why some tumors exhibit accelerated growth after certain immunotherapies. The research suggests that blocking the TGF-beta pathway, which can act as a growth suppressor in some advanced cancers, might inadvertently remove a critical brake on tumor growth. These findings could help refine precision therapy strategies for cancer patients.
