Dear All, I am about to start Keytruda as my blood tests shows mismatched repair deficiency for which immunotherapy is advised. I have chronic asthma and so am really scared that the treatment may harm my lungs. I have read that keytruda can have bad side effects. Since in my case chemo has not worked I have run out of options. Please let me know if any of you have had keytruda and what was your experience.
