Definitely every day that ticks away give the cancer a chance to spread ( assuming that's what it is) those two weeks can mean a big difference in treatment some drs will tell you cancer doesn't move that fast - the truth is - they don't know. My cancer was deemed well differentiated - (slow growing) it took my biopsy 10 days for the results (GP told me - dumbass ENT he sent me to wanted me to wait until he got back from vacation - January 4 - my biopsy was dec10) that was unacceptable - anyway at that point other than the tumor in my tongue - my lymph nodes were clear - confirmed by a ct of head and chest - dec 21- by dec 27 I could feel a lymph node under my chin - my MRI on jan 6 came back clear - but it was there because I pointed it out to my dr. The morning of surgery and he was surprised..it didn't matter as he told me straight up on our first meeting - you're having surgery and I'm removing part of your tongue and 40 nodes. That lymph node did have cancer in it and had broken through the capsule. Because of this i was recommended for rads and chemo despite him being certain he got it all - my point is every week that passes is time you could already have started the process if it is cancer. My GP was priceless as he gave me the results - set up all my tests for the next day and had my results the same afternoon. Had I waited for the ENT to get back from vacation... I wouldn't even have started the process and as it stands the first MRI date they'd scheduled me for was the day I had my surgery via a different ENT. Push. Make noise find out as soon as you can - this is potentially cancer - time is of the essence. And making you wait three weeks is not only insensitive but negligent. IMHO ... Take care.
