Welcome! No-one really wants to be here, and not the Christmas surprise you want but it’s a warm and friendly place on the network, with good advice from people who have first hand experience.
First advice is, don’t Google! Breast cancer is not one thing, it’s a mixture of many facets and many complexities. Treatment is therefore individual. Two people with apparently the same diagnosis may have different treatments, because other factors may come into play. Reports on Google are not moderated - they may reflect one person’s view but they may not be accurate or up to date.
Second, your medical team will be very important. You need to feel comfortable with them and trust their advice. Have you someone who can go with you on your first appointment? Can be really handy to have someone to take notes (also useful to make out a list of questions beforehand) as this can feel like a whole new language and it’s easy to forget things in the rush of new information.
Others on the network can give good advice on how you keep your children informed but not scared.
Once you know what treatment is recommended and have a plan, things do become a bit clearer and it’s easier to focus on each step. It’s hard but try not to think too far ahead - you would not be the first to worry about something that never happens! One step at a time. Best wishes.
