"Lack of information"

I saw my GP a few weeks ago, due to an irregular feeling in my breast. The GP examined me and asked if it was a little lump in an area but proceeded to say he was not worried, but would refer me to the breast clinic, he said he would note on the referral 12kg or so unintentional weight loss I had. 

I phoned the appointments office to find out the waiting time, I was told around 15 weeks but asked if I could accept a short notice appointment in forth valley. 

I have no idea if theirs different urgencies of referrals for the breast but the potential to wait 15 weeks seems a little long.

A suggestion that perhaps it could be explained to patients if there is different levels of referrals to put minds at ease.
