Bilateral breast cancer w sentinel node removal: Lymphedema prevention

The first time I had breast cancer...DCIS with 2 nodes removed...I was instructed to NEVER have BP, blood draws or shots in the affected arm because of the possibility of lymphedema. Last year I had IDC in the other breast with one lymph node removed. I have asked for blood draws from other parts of the body, but I have been unsuccessful finding a place that will accommodate me. Neither my Dr’s office nor the two cancer centers that I have gone to provide this service. It surprises me that this is not routinely provided at cancer centers. The ones that I have gone to are respected companies, not second rate places. I would like to find a lab that can accommodate me. I see that there are a significant number of ladies that are in the same boat as me. I wonder if the cancer centers are only considering their expense and/or liability in providing this service. At one place I asked the Dr what they would do if I did not have arms and she told me I was carrying the issue too far. To me it is obvious that there is a need, not only in the breast cancer community, but in the health field as well, for this service. I feel that even though these cancer centers advertise how wonderful and up to date they are, they are not really interested in the welfare of the survivor as they advertise themselves to be. I would appreciate anyone else’s thought on this issue.
