I am a 37 year old female. I have a slight bump on the roof of my mouth ( smaller than a tooth) also have a red patch that is behind bump. This patch fades, gets smaller, larger, darker, and fades again... Lately the red patch hasn t gotten any bigger or darker, and with the lump on my hard palate, I don t know if it has grown, as I just noticed it.... What could it be?? What should I do??
