If this was a recent study you read, they were talking about culture petri dishes that were being "fed" vape. The amount of vapor they were exposed to (for cell tissues) was likely MUCH much more than a live human being would be exposed to over a life time, not to mention that petri dishes DON'T function the same way as live tissues let alone live animals let alone human beings.
I know what I'm talking about, both my parents were geneticists and I also worked in that field for a while after college. So it's easy for me to spot "junk" science, vs. "actual" science.
Vaping is currently politicized, with big tobacco trying to save itself, the states and federal government trying to figure out who to "choose" and how to "tax." Britain, which ALSO already has established, cultural regulations for vaping IN PLACE has been studying vaping for quite some time. The figures you are hearing about 95% safer than smoking, well many of those studies were completed by the Royal College of Medicine and have been ongoing for some time.
There are lots of researchers who are refuting this kind of "junk" science nowadays, overseas but also here. There are not yet TRUE longitudinal studies done yet of vaping as it is still relatively new.
There have been NO cases (that I know of) where "vaping" has been conclusively determined as a cause for cancer, and if there were, we would have HEARD about them, as big tobacco would GENUINELY want to TRUMPET that to the skies.
As a former smoker you are already at risk for a cancer diagnosis, as well as heart attacks, COPD, etc. Unless you stay switched to vaping. Vaping does not cause cancer, and as someone who ALMOST got the dreaded COPD diagnosis, I will tell you that my lung tissue has recovered nicely over the past 7 months. That tells me my body is healing from smoking, and my doctors concur. They do not believe that vaping causes cancer, and nor do I. They do inform me that my YEARS of heavy SMOKING place me at risk for cancer and that the best thing I can do is to continue vaping.
Also, I would take cancer over COPD any day of the week. You can BEAT cancer, you can mostly merely HALT the progression of COPD although some folks DO see some lung function recovery IF THEY VAPE.
Do not let a single study (that it sounds like you don't really understand) let you go back to smoking.... Unless you would like to die of COPD and/or a heart attack like your ancestors.
Tell me.... If vaping is 95% less risky than smoking, (and that would INCLUDE cancer diagnoses) why would you return to something that is 95% MORE likely to give you cancer AND COPD and a heart attack? That makes no sense.
Of course, you can let the media and junk science control you if you want. Or do a little more research.
Much of "media" nowadays is simply not the truth. You do understand that just because "the media" says it, doesn't make it true, right?
