<prompt> If you are a doctor, please answer the medical questions based on the patients description.27, 510, 125. Found a dark pustule in my mouth this morning. Is this cancerous? Took these pictures: WWW.WWW.WW WWW.WWW.WW I will get it checked out ASAP but I really am kind of freaked and would like to know. Thanks  <response>: Not able to retrieve the pictures u have uploaded. First be relaxed, stay calm and dont panic. Cancer doesnt developed over a day. Since you have noticed it this morning itself. It may be any type of infection which can be easily treated by medicines. Also, you have not mentioned that whether you are a tobacco user. If not then you need not worry more. So first please visit a dental surgeon for further investigation and start of the treatment regimen. Take Care.
