Sorry you have cancer. It’s not what anyone wants.
One of the most helpful things some one told me is that for many people now, cancer is a treatable illness.
Everyone is different but we told everyone we knew. It’s surprising how some people who I thought were very good friends did not provide much support but others, unexpectedly, gave me support. But no one can give you support if they don’t know you need it.
Best wishes. Many of us find with having cancer, it turns out we are much stronger than we realised.
