Nodules???

[Alice]

Hi, I have been away from the board for a while and I just have a question. My onc doesnt want tests done until there are symptoms and I understand and agree mostly with this. One of the women in the group I go to didn't have any symptoms but had a scan done and now will be on chemo forever. i also had a scan done but for another area of the body ,and another reason, that just happened to catch a portion of the lungs and it showed that there were multiple nodules in both lung fields. I know there are other things that may show up but in reading some posts I see some people reffering to micro-mets. How big are these and are they confirmed as cancer or could they be something else? My nodules are stated to be .5 mm in size and can not be determened as carcinoma. They have not changed in a 3 month period so I am optimistic but at the same time if it was an infection or something else it should have been gone by now.
