I would be interested to hear people's experiences (good and bad) of how employers have and are supporting you through your treatment. I was so lucky that I worked for an understanding employer when going through my treatment for breast cancer but I am not sure other people have good support.
Since my treatment, I have now set up a HR consultancy and I am working for myself - it's both scary and exciting but I don't think I would have taken the plunge if I hadn't have seen that life is too short not to give something a go if you really want to.
