What cellular mechanisms in aggressive tumors allow them to evade therapeutic success?
Answer
They frequently possess genetic mutations that allow them to rapidly evade cell death signals or quickly repair DNA damage caused by therapy.
The resilience of highly aggressive cancers often stems from their sophisticated internal biology, frequently driven by specific genetic mutations. These mutations grant the cancer cells a survival advantage by enabling them to actively ignore or bypass the molecular instructions that would normally trigger programmed cell death (apoptosis). Additionally, these resilient cells are often highly efficient at repairing the structural damage, such as DNA breaks, that cytotoxic therapies like chemotherapy or radiation are designed to inflict, thereby nullifying the intended effect of the treatment.
