extra axillary lymph nodes

Last month I started with night sweats,, nausea, weight loss and headachesand some stomach pain. No other issues. I went to my primary which precribed me Cipro x 7 days. She also requested labs to be drawn. My WBC was 2.3 Everything elsa WNL. Recommended ultrasound of stomach. Results; mildly enlarged liver, speen and a gallstone. She recommended I see a specialist. Made an appointment 3 weeks later.  Blood drawn WBC WNL and Hemoglobin 10.1. Weight loss 4 lbs. Still with sweats, headaches, low grade temp. He ordered CT scan of pelvic,stomach and chest area. Returned for results; Extra Axillary lymph nodes, small. Specialist recommended wait and see, can't garantee not cancer. Return in 6 months. What is you opinion. I am 37 years old, female, 3 kids,(c-section,tubal ligation) Hypothyroidism, (Synthoid 288 mcg,)  Lap band 1/2008, Hx of nephrotic syndrome. Very High family risk of Cancer. Father died age 50 with Colon CA. Do CT scans really see everything,? Should I get a mamogram (mammogram) or  other ultrasounds? What about removal of nodes? I am upset because I waited 3 hours in the specialist office, only to be rushed out. He really seemed annoyed and my questions really weren't answered.
Thanks
