Welcome back to Rad Onc Smart Review. This is Episode 4, Mechanisms of Cell Death & Response.Last time, we explored how radiation can cause major structural damage to chromosomes. Today, we're diving into the consequences of that damage, looking at the diverse ways cells respond when faced with radiation injury – focusing on the distinct pathways leading to cell death or dysfunction, including apoptosis, necrosis, mitotic catastrophe, autophagy, and senescence. Knowing how to differentiate these is key for understanding treatment response.
