Conversation: The conversation between human and AI assistant.
[|Human|] I am a twenty-one year old female, smoker about 1-1.5 packs a day, do not consume alcohol. I do have Hashimotos Disease, and some dental issues such as abscess in the past. I developed a dark red circular patch on the roof of my mouth through the course of a week and after gargling salt water and possible trauma by touching it with my tongue , it has increased in size to slightly smaller than a dime. I am petrified that it may be oral cancer , as my dentist said he wants to refer me to an Oral Surgeon. There is no white present on the spot, and the dentist commented that the tissue (bone) on the roof of my mouth feels slightly softer. Does this signify cancer?
[|AI|]  Madam, as per of your given history, there are very little (almost negligible) chances of this redness to be oral cancer. This redness may be attributed to heat and tobacco effects of smoking which may be at maximum an erythroplakia patch, it has nothing to do with Hashimoto disease. Erythroplakia is a reversible pre-cancerous condition, caused due to tobacco, having limited potential of turning into cancer, hat also, if it persists for more than 3 weeks period, increases in size or presents with numbness of that area. First you must quit or at least minimize smoking, second you maintain a good oral hygiene, and keep a watch for another 3/4 weeks related to all above sign. Lastly, you can see an oral surgeon who can do simple test like exfoliating cytology or biopsy to verify above findings. At such a young age, it is very rare to get Oral cancer. This red patch will definitely fade away within few weeks, IF YOU QUIT SMOKING
