Hi. It sounds like youve just been diagnosed and are trying to get mire info. Usually you get allocated a clinical nurse specialist who you can talk through worries with. Iso you know who yours is and how to contact them. The nurses on the forum or the phone lines here may be able to help. But each person is different so any advice would be general i would think.

It may help to give a bit more detail about the type of cancer you have so that others with the same type can offer some suport. 

You also said in you post that the hospital has said the grade has changed. Did you mean grade or stage. Grades describe how different and fast growing the cancer cells are. Staging describes extent of the cancer. Sometimes as mote tests are done more is known about both which can help inform treatment plan.  

I hope you get the kind of answers you are looking for.
