My 21-yr-old daughter has a swollen tongue on the lower right-hand side. She says it has been like this for about a month. She has noticed some occasional discomfort swallowing food but apart from that, there is no pain. As a mom who has a best friend recently diagnosed with oral cancer, I am really concerned about my daughters condition!Sorry to waste your time - didnt realize there was a charge for this.  As a Canadian, Im not on-board with this type of medical service delivery.Regards, Cathy
Hi Cathy and welcome to Chat Doctor Thank you for your querry.it is unlikely to be cancer, almost impossible, but it can be sign o allergic reaction, insect bite or respiratory infection. She should try to find food which can be allergen. In some cases tongue swelling may be very dangerous as it can block breathing. She needs ENT examination to rule our throat and mouth, teeth infections. Wish you good health.
