<s>[INST] Hi doctor, This is regarding the health of my 57 year old father. He is a non-smoker, vegetarian, and a non-drinker. He had a complaint of a low voice since the last 10 days. Yesterday, he had to visit an ENT for a check up. They did a video laryngoscopy and found a small lesion at the vocal junction. I am attaching the photos for your understanding. The doctor suggested medication. He told that there is a 90 % chance, it will be normal in a week. If not, we have to plan for a minor surgery. Could you please let me know how serious it is? Is surgery required? If yes, how painful will it be? [/INST] Hello. I have seen the pictures (attachment removed to protect patient identity). For further queries consult an internal medicine physician online --> </s>
