A new study reviews how cancer-associated fibroblasts (CAFs) influence lymph node metastasis. Researchers identified various CAF subsets that interact with the tumor microenvironment, promoting cancer spread. By targeting these specific subsets, new therapeutic strategies can be developed to inhibit metastasis, potentially improving patient outcomes. This breakthrough offers a deeper understanding of CAF heterogeneity and its role in cancer progression, paving the way for more effective cancer treatments.
