5-ALA-induced fluorescence

5-aminolevulinic acid (5-ALA) is a substance used in medical procedures to help visualize certain cells, like cancerous tumors. When patients take 5-ALA, their abnormal cells absorb and convert it into a fluorescent compound called protoporphyrin IX. Under special blue light during surgery, these cells glow bright red, making them easier for doctors to see and remove precisely. This technique improves tumor detection and removal accuracy, potentially leading to better patient outcomes. Essentially, 5-ALA acts as a targeted marker, illuminating problematic cells to aid in more effective treatment.
