Dont let 'fear' hold you back from reclaiming your life with something that might help you live a better quality life.
I dont think anyone can give any guarantees at this stage with regards to the safety of stems long term. From what I remember, the risk of cancer was much higher with the use of embryonic stems.
I can reassure you that I have had cancer markers done for another reason recently, and they are all totally normal. ( I received adipose stems May 2017)
There are conflicting reports of the role of antioxidants in the development of cancer in the literature. So, there are always risks with everything we try to throw at t and h. However, I guess you want to take a calculated risk when it comes to experimental medicine, which is what stem cell therapy still is. Very hard at this stage to ascertain the risk when there are limited/ no studies to put your mind at ease. All you really have to go by are ancedotal reports and commonsense.
I received my adipose derived stems from here ..... >

You could possibly email Dr Ralph Bright about your concerns and questions.
For transparency, I will mention that I ended up with a heart arrythmia 2 days post the stems, and felt a bit weird (heart wise) on the table when injecting the lignocaine (probably contained adrenaline). However, I have a history of heart problems, so on reflection, I dont think this was necessarily a complication of the stems directly. Just my screwed up health at it again.
I had spoken to one former patient of the clinic I attended who had a dramatic improvement in his tinnitus and hyperacusis as a result of receiving intrarticular adipose derived stems for his hip pain (his original intent was to avoid a hip replacement). He mentioned that he had a hearing loss, and that his h was such a problem that he used headphones everywhere he went. Months after the procedure, he no longer has h and barely hears his t. He has also successfully avoided surgery.
I didnt have the stems for my tinnitus. I had severe joint pain at the time. I hoped my t and other health issues would be helped, but honestly didnt have high expectations that my tinnitus and hyperacusis would improve so significantly.
I was habituating at the time of the stems, but I can say confidently that:
One of my noises has completely vanished (a bothersome, vibrating engine noise that I would hear at night)
The reactivity of my tinnitus has significantly improved; hence my hyperacusis
My t has backed off, but as I said I was already habituating.
My spikes have dramatically effed off. I would average a nasty spike every few months, which made habituating very difficult.
Ive had further hearing tests that havent demonstrated an improvement in my hearing thresholds, so I tend to agree with Sam at this point, that stems havent repaired my cochlea (but I didnt expect it to).
I think any doctor dabbling in medicine outside the box is going to attract media and medical watchdog attention. I dont know the particulars, but I wouldnt let that deter you from considering stems. The clinic I attended was involved in a case involving an elderly woman, whose demise came days after a stem cell procedure. The way the story was portrayed in the media made it seem it was stem cell related, but it was NOT.
I spoke to Chloe Sohl a few times prior to my procedure. As Sam has mentioned, her hearing loss and t was due to an autoimmune condition of her ear, which responded beautifully to the adipose derived stems, with no complications. She sometimes hears her tinnitus, but is very mild and easily ignored. Her hearing in one ear was completely restored and the other ear improved significantly also. I agree that I think it depends on the underlying cause of your t and h as to whether stems will help you.
At the end of the day, you wont know if they are going to help you unless you give it a try. As long as the risk for harm is minimal, what have you got to lose?
I hope this helps
