Diagnosed with anal cancer.

I have many on going health issues which have been going for years and now I have just been diagnosed with anal cancer. I am finding this very hard to cope with. I have spent the last two weeks going fot different scan and other appointments and am completely exhausted from  them.Treatment is going to difficult due to my other health issuies. I am finding it difficult to explain to people about my cancer and being completely honest a bit embarrassing.
