Why LOOK for mets?

Everyone is different, but you asked the question.
The reason I have scans done every two months is because I had bone mets. And although my markers are normal and I have no symptoms (currently on herceptin alone after 1 yr tax/carbo) there is always the possiblity that the cancer cells will spread to the organs and that just ups the ante in this battle.
Prior to having been dx with mets, my dr only did annual scans and had tumor markers done every 3 mos. This was supposed to go on for 2-3 years, but unfortunately I only made it a year before bone mets were suspected and then confirmed.
If your not dealing with mets, then just report anything unusual to your dr.

I requested and am receiving Zometa to strengthen my bones anyway. As for liver function, the routine blood test is quite sensitive to liver problems. I am just saying.

Ruth,
All information here is valuable. I was having the same question (why tests?) as my onc isn't prescribing any. With the responses here at least I am getting different viewpoints pro and con. I think it would be better to find met earlier on rather than later to avoid a more severe treatment.
Thanks for posting your thoughts and all the best to you.
