Incapacity Benefit and my local helpful job center

I was on SSP from my employer for 28 weeks then applied for Incapacity Benefit, I have been on it six weeks and have been called to attend a work based interview in 2 weeks, they said that they left me until I had finished all my treatment ( had my last radiotherapy 6 days ago) how kind of them! I guess they assume that now treatment is finished I am 100% fit and healthy and ready to get a job!!! the thing is I have a job that is being held open for me by a fantastic employer and more so its a job that I love. When I feel fit and healthy ( which is not at the moment, all I want to do is sleep) and my GP says I am well enough to return to work then I will. I thought that the government was sympathetic and understanding to people with cancer, when I asked them this I was told they were and that there were allowances but not for my type of cancer!!!! I have worked since my daughter was 8 months old she is now 20. my husband works full time and we never asked for anything until now, but as I seem to have the "wrong" type of cancer it feels like I am going to be bullied back to work. I now feel even worse, am feeling stressed and am finding it hard to manage the pain........... so thank you to my local job center for helping me recover from my breast cancer!!! I have a letter to fax to Mr Gordon Brown tomorrow and have contacted my local MP. I just wonder how many other people are going through the stress of cancer and are being treated the same when we all know at least one person who has fiddled the system for years!!!
