I had multiple visits (over an extended period of time) with my dentist, my GP and finally an oral pathologist at a major dental school, all of whom told me the very visible, growing, and painful lump on my tongue was nothing serious and I didn't need to worry about it. They assured me I didn't fit the risk profile for oral cancer, and the pathologist said the fact that the lump was painful was almost certainly proof that it wasn't cancer! However, when I finally insisted on seeing an oral surgeon, he was the one who recognized the immediate need to get a biopsy, and he then put me in touch with a medical oncologist who has been in charge of my care ever since. (This was way back in the days before the internet, and information on OC was really scarce.)

I guess this illustrates that sometimes you can get a series of wrong opinions, and if collectively they don't make sense, you have to keep pushing for reasonable answers.
