As I said in your other post and which you acknowledged: keep in the front of your mind that it is the POLYP that is cancerous. When the Surgeon removed my breast lump he told me "I had in my hand what I expected to find" and I thought "Lucky you!"
..... however, at histology the lump was found to have 'changes within' so lymph glands were removed which were clean. Preventative treatment followed.
I suggest that you make notes B4 the next appt with all your worries. That way you won't forget to ask the important questions to sort things in your mind, my Surgeon insisted on my having a list each morning when he did the Ward round: he was so thorough with his explanations that I didn't need the list
. Some medics do not have the foresight to put themselves into where the patient might be: because they are dealing with similar situations they often don't make an effort to put the patient's mind at rest! So do ask.
Don't feel that you are being pushed into any procedure or treatment that you aren't comfortable with. Even if there is spread don't feel that you have to start treatment until you are ready to proceed. 24/hours of going home to think won't make any difference. Once I got into the swing of treatment and apps. I felt that I was tackling any problems sooner rather than later.
Do ask when you are at the appt. which support web-sites are the best to access, hopefully you will have a dedicated Nurse who you will be able to contact when necessary. If this isn't offered, do ask.
If you have delayed reaction to medication, ring as soon as you get the appt. to make sure that the Staff are aware. It may require medication the night B4 for example, or a different relaxant to what is used. I find
Ativan good at relaxing me .... a small blue tablet and I was away, didn't care who saw my beautiful body
