Working With Lasers

I have been working with A Class 4 Laser Hair Removal system for several years.I developed Metatastic Papillary Thyroid Cancer and have had surgery and radiation for treatment. I have been told by 2 Phycians that they feel my cancer is related to my working with the Laser. This has been my primary job for no less than 30 hours each week. Does anyone out there have a simular situation or know of anyone that does. Of course it is imposible to find anything on the internet ,as the Laser companys will not do or say anything that might cause a decrease in sales. As far as I'm concerned this isn't about money, it's about the safety of other health care providers and if this is a possibility, the Lasers should be regulated as a possible cancer causing device. At this point the only protection advised is...always wear your protective goggles. Looking forward to any help out there and thanks for you time,

I spent some time working in a therapy clinic and we used the new laser therapy. I know that we had to be careful with cancer patients not to use the laser near any know or potential cancer sites as the laser stimulates cell growth and regeneration and could cause the caneer cell to grow faster and possibly spread. I don't know if this helps but I hope it does.
