The main reason for me to have a thermography came about when, on my 50th birthday, I was faced with the choice of having a mammogram every 2 years through the population screening or not.
Mammography is not a good choice for me emotionally but to do nothing about research didn't feel right either.
That's how I ended up with thermography.
I find it reassuring that my breasts are monitored this way every year and if there is a noticeable change in the pictures I can still have a mammogram.
