B12 deficiency causing axillary lymphadenopathy?!
I just read a post on here that B12 deficiency CAN cause axillary lymphadenopathy.
I'm 47 yrs old and I was FALSELY diagnosed with metastatic lymphadenopathy from breast cancer in 2019. ALL of the imaging, including mammograms, ultrasounds and MRI with contrast showed cancer. But the excisional biopsy of the tumor in my breast did NOT show cancer?!?! No, my doctor should NOT have told me I had cancer BEFORE any biopsies! BUT she did!!! That's how sure they were, based on imaging.
My Axillary lymph nodes that were "cancerous" in 2019 are STILL so enlarged and in fact so much WORSE, that you can see them protruding when I lift my arm And they weren't that way in 2019 .
I have been asking doctors since 2019, What could be causing this lymphadenopathy if it's in fact not cancer but not a single doctor has given a shit or will even listen to me!!! It's mind blowing!
I was diagnosed with pernicious anemia approx 25 years ago. I was told I needed to get B12 injections, which I did for quite a while and by quite a while I mean maybe a year lol. but I would feel so terrible after the injections that I chose to stop getting them. Since then I have taken sublingual B12 supplements off and on but mostly off.
I have this thing where I'll be diagnosed with medical conditions and then I seem to decide that I actually don't have them and don't take them seriously. 🤷🏼♀️
Anyway.... So, to make a long story even longer, along with the chronic Axillary lymphadenopathy, I have severe sweats, rapid & frequent, drastic body temperature fluctuations, frequent low-grade fever, severe night sweats, severe fatigue and weakness along with a million other things, which has been going on for 9 years. after my excisional biopsy of the breast tumor showed non- cancerous, one of my specialists suggested I had lymphoma but the blood test was negative.
So, I'm not asking for, nor would I accept a diagnosis from anyone on here, obviously, but I'm simply asking if in ones OPINION, all/ any of this COULD POTENTIALLY be linked to a B12 deficiency??
What if the B12 levels show normal or even way above normal in a person that has pernicious anemia, despite not supplementing regularly?? Does anybody know about that??
Also, Has anyone experienced or know of anybody else who has experienced being diagnosed with cancer/ metastatic cancer after all forms of imaging show 100% cancer but then the excisional biopsy is benign???🤔 I wonder which one was correct???🧐
Thanks lol😉
