Anxiously Awaiting Colonoscopy/Gastroscopy Results

Hello everyone. I don't want to write out a novel for you all, but I do want to write out as many facts as I can, so please bear with me.

To start, let me say that I am a healthcare worker...a lab technician specifically. I have a pretty good understanding of the how the human body works and disease processes, etc. This may be to my detriment, as I am pretty sure that many of my physicians over the years have considered that I am a hypochondriac, when really, I just feel that I am either fortunate or unfortunate enough to know what could possibly be wrong with me when I experience symptoms.

It has only been in the last couple of years that my concerns about cancer started to really be something that I thought about. No concerned that I HAVE cancer, but that I will, eventually. The reason I say this is because my family history, frankly, is terrifying. To start, 3 grandparents died of colon cancer in their 60's/70's. My fourth grandparent had cancer, but died to hear disease first. On my maternal side, I had an Uncle who died of cancer (possibly stomach) at the age of 33, and in the past 3 years I have had three Aunt's diagnosed with cancer, two with breast cancer and one with Lymphoma. I also had two cousins diagnosed this past year with Lymphoma and breast cancer. On my paternal side, one Uncle lost a kidney to cancer and one of my cousins survived breast cancer in her 20's.

So...you can see with a family history like that, it is hard not to consider that cancer runs strongly in my genes. 

Anyhow, what really brings me here is that about 2.5 years ago, my iron deficiency (that I had for several years prior) finally turned into anemia. My hemobglobin started to drop over a course of a few months to the point that I was referred for a course of iron infusions before I became in need of a blood transfusion. The infusions worked well, I was no longer anemic. My GP has continued to monitor my iron and ferritin levels and over the last years, they have once again depleted. I have currently on week 4/5 of another round of iron infusions. Although my hemoglobin had not yet dropped significantly, I have experienced debilitating chronic fatigue over the past year and my GP had hoped that getting my iron and ferritin levels up would help. My ferritin was checked this week and is going up nicely, but my fatigue has not improved in the slightest. She is also concerned because after evaluating my diet, she feels that there is no explanation as to why my iron/ferritin levels are so unstable. 

I also have severe GERD. Being that my last gastroscopy was over 3 years ago and my last colonoscopy was over 9 years ago (both completely normal), she felt it was a good idea to refer me for both. 

I went this past Tuesday for my scopes and I am not entirely too sure what to think. On one hand, the pathology was not sent as urgent and the surgeon made no mention of any tumors or anything of significance, so that surely must be good news? However, during the colonoscopy, the doctor removed one polyp and made a comment to the nurse while taking a biopsy that "that is not the colon". During my gastroscopy, he removed what both he and the nurse stated was a large polyp. I was told to make a telephone appointment with him in 4 weeks time, so my initial thoughts are that everything must be okay if there in no hurry. But I can't help but be concerned by his comment when taking the biopsy.

Aside from the iron deficiency, I have had diarrhea or loose stools with urgency several times a day for the past several months. I have also experienced nausea occasionally off and on for the past several month and of course have severe fatigue that has gotten worse over the past year. The only time I have any bleeding from the rectum is when I get constipated (which I believe is due to an anal fissure that I have had for years). I have always had difficulty with bowel movements, though for years the difficulty was constipation...now  of course, it is diarrhea. 

With all of this information...I am aware that all I can do is wait for the pathology results to truly know anything. But are my experiences at all similar to anyone here? Can anyone give me reassurance and help to ease my anxiety?
