I have received a letter from an oncologist referring me to a specialist hospital, as I have some time of rare lump that is undiagnosed after ultrasound and MRI, do the hospital know more than they are letting on? I haven’t been told anything about what this lump may be  but would this be because they are expecting it is cancer but can’t say anything until they know for sure? Also the lump has been growing for two years and I do have lymph nodes up on my neck which I haven’t told the hospital about if I had had cancer for 2 years would I be feeling ill by now?
