<s>[INST] Hello doctor, I have had this lump on my hard palate for about three months now. It is located near the middle line and a few millimeters to the left. It is about 2 x 2 mm in size, pretty round and it does not hurt. I thought this might be torus palatinus. But, I heard that this torus is mostly symmetrical and my lump is only on one side of the palate. In the picture, it looks a little red because I scratched it with my finger nail. It was just a little bit more red than the other side of my palate as I scratched it. So, what could this be? I am scared that it might be some kind of cancer. [/INST] Hi. Torus palatinus. If torus palatinus, then it is completely harmless and require no further investigations. Revert back with the answers to the above questions to a dentist online.---> </s>
