Tumor response

Tumor response refers to how a cancerous tumor reacts to treatment, such as chemotherapy, radiation, or surgery. It measures whether the tumor shrinks, stays the same size, or grows. A positive response usually means the tumor is shrinking or disappearing, indicating that the treatment is effective. Physicians assess tumor response through imaging tests or other methods to determine the success of therapy and guide future treatment decisions. Monitoring tumor response helps in understanding how well the cancer is being controlled and if adjustments are needed.
