Waiting Time.

Hi all, I have been told I require a total duct excision due to bloody discharge from right nipple. I am unable to feel any lump and mammogram and sonogram are clear but the consultant feels it is the only way to rule out cancer and should it be down to other causes ie papilloma etc surgery would be the best option.  I did have a cyst drained from the same breast 18 months ago. I am very worried but understand and am glad they are being so thorough. 

My question may seem silly but my initial consultation where I was informed I would need an excision was on the 10th. The Dr told me the follow up letter will take a few days and surgery within 4 weeks. 

I called today as can not see any follow up letter in my NHS app. The admin staff was great but told me they could not see any letter or referral and gave me the number for the surgeons secretary. The number rings out with no option to leave a voice mail.

my question is how long did was your wait between consultation and surgery? I don’t want to be a pain by calling etc if this is a normal wait etc as I know everyone is very busy. I am just worried as you can imagine. 
many thanks
