Told just over a week ago I have her 2postive. Totally scared, trying to be very positive . On letrozole, staring herceptin within two weeks. Trying to get through the fear every day .going on bike rides to challenge my strength. 

Welcome to the forum, Biker, sorry to see you’re here, but glad you found us.
Just being diagnosed is a huge shock, but there’s no reason not to be positive about it all, as you say.
Although you could certainly do without it, thankfully you can now be treated to get it sorted out.
Do look at the other parts of the forum, such as ‘going through treatment’ where you will be able to chat & get support from others where you are now & further down the line.
