Tinara, I hear you. Of course you are scared right now, and you don't have enough information as to what is going on to be able to deal with this yet. It is very scary to think that once again you may have to deal with a cancer again. But, you don't yet know this. Wait for the biopsy and then the results. Try not to let your mind wander to that dark space. Tell your self to STOP. Then redirect your thoughts elsewhere.
Believe me, you will handle whatever comes your way. It is the only thing to do. We all just carry on, even though it can be very difficult.
By the way, my husbands cancer returned within the first year. He had surgery and 12 months later is doing fine.
Keep yourself busy, and let us know how things turn out,
Tammy
