My hematology oncology Dr said straight-faced i would not lose my hair. HA! Read side effects of Melphalan and BMT conditioning chemo.
I just googled Tagrisso. Interestingly, it does not say for sure. Thinning does not mean gone. I met women on breast cancer .org who used cold capping and ended up with loss but hair that was noticeably thinner with one having patches done. Most were glad they did it. ME? I do not like BALD. But i did take pictures and found way more acceptance the 2nd time around.
I will say that nearly 5 years into this cancer stuff i have a GREAT hat collection. I wear them all the time or have one with me. My sister on her cancer journey wore baseball caps and the hair things with the scarf that fell across the shoulders or down her back. Choices.
Ultimately your medical team has no idea. That is my Med Oncologist Dr. Patel said just allow it to happen. Your hair nearly always grows back. Mine did twice.
