Keytruda is an immunotherapy treatment that may help the immune system recognize and fight certain cancer cells. Possible signs that Keytruda is working include reduced tumor size, stable disease, improved symptoms, longer disease control, and stronger immune activity.
Still, every patient responds differently. Some people may notice symptom improvement, while others may need imaging scans and medical tests to confirm response. Always discuss your progress, side effects, and treatment expectations with your oncologist.
