Researchers have made advancements in cancer treatment, with one approach involving the use of photoresponsive nano-PROTAC to reprogram cancer metabolism and enhance immunotherapy. A new nanoparticle has been developed that can reportedly cross the blood-brain barrier, and another treatment has been found to eradicate breast cancer tumors without harming healthy cells. However, the specifics and outcomes of these treatments are not entirely clear, with some reports focusing on related technological breakthroughs.
