Hello, I think, I have answered your query few times. Firstly the appearance itself is not diagnostic. It can be indicative. Do not fear or panic, please meet an ENT surgeon and do a biopsy. It might not be malignant. Then you will be relaxed. If at all it turns positive, you are already mentally prepared, treatment can be started.
Next Steps
Meet an ENT specialist locally
