[|Human|] I have noticed a vein in my lip when i run my tongue over it. I can also notice a bump in my lip with my finger or tongue. When i stretch my lip out, i can see that vein there. I have noticed some pain with it. It is not blue or pulsing. I had jaw surgery a year ago and that area of my lip is still a little numb. I have also used chewing tobacco for about 4 years.
[|AI|]  Hi, Dear. Thanks for the query to Chat Doctor virtual Clinic. I am Chat Doctor. I studied your query and understood your health concerns about your Sister. Cause of lumps on the lip-You seem to have bump which needs to be confirmed and ruled out for any adenocarcinoma of the lip, due to tobacco. The vein to the lump indicates its vascularity. I would advise FNAC biopsy and excision biopsy later on by ER Surgeon. This is how you plan treatment with your doctor. Hope this would resolve your query. Write good review and hit thanks after reading this reply. Welcome for any further query to Chat Doctor and to ME. Wishing you early recovery.
