Detailed Answer:
Warm Welcome. I appreciate your trust in HCM and assure you are on best portal on the globe for expert online medical services.
I have thoroughly reviewed health query you raised, and well realize all of those concerns. Being your physician, I will take care all of them today and will extend my expertise to solve the problems.
Based on your report, current risk of nodule being malignant is around 15% which is higher than 5% when there is less than a centimeter size. So size has definitely an impact on chances of malignancy.
You didn’t mention your age so I can’t comment on whether you are in menopausal state or not though hot flashes does indicate a sign of hot nodule which most of the time is not cancerous. You also need to comment on any other symptoms you are experiencing along with hot flushes.
Regardless of your symptoms, you are advised to get a FNAC (fine needle aspiration cytology) test to confirm whether is benign or cancerous. Additionally
thyroid function tests, if not done, are necessary to be done.
Hope I addressed all the concerns you have. Let me know if you have further questions. I will be more than happy to clear any doubts. Keep a follow up to see how you doing.
