wow a very interesting story about our journey dealing with breast cancer. I only had 3 lymph nodes removed from my affected arm which is left arm. I had bilateral mastectomy as prophylactic measure to prevent recurrence to my right breast. Luckily i can take BP and draw blood from my right arm since no lymph nodes removed, I have to remind the nurses at my oncologist office even though they have my record in front of their face. We need to be ambassador of our own health and not allow them to touch the affected arm. If they have to they can take BP on the lower leg which is okay to do so as long as you don't have any problem with lower leg. Always ask for a second opinion if possible before taking a major decision such as having surgery or starting a new treatments.
