Chemotherapy resistance

Chemotherapy resistance occurs when cancer cells adapt and become less vulnerable to the drugs designed to kill them. This can happen due to genetic changes in the cancer cells, enabling them to withstand treatment, or through the activation of mechanisms that help them survive despite drug exposure. As a result, the chemotherapy becomes less effective, making it more challenging to control or eliminate the cancer. Researchers are continually studying this phenomenon to develop better treatment strategies that can overcome resistance and improve outcomes for patients.
