Please help, I am sick to my stomach with worry. My mom had double mastectomies and sentinel node biopsy performed. While she was in the recovery room, I was holding her hand. I noticed blood on her wrist band with a small chunk of tissue that looked like a blood clot or piece of the breast tissue. I was squishing it with my fingers to see what it was. It disintegrated to practically nothing. However I have been having panic attacks since then because I feel terrible that I could have been spreading cancer cells. What if she got it in her mouth, eyes or bloodstream? Also I was touching my family after including my 4 month old daughter. I cannot stop crying with guilt that cancer cells could have been in the tissue, whether it was lymph node or blood clot or other. What if I caused her cancer to metastasize to places it wouldn't have. Please help me, I feel terrible and all I was doing was trying to see what it was to give myself some reassurance. Is it possible that I caused metastasis for my mom or anyone else could have gotten cancer this way. Please help me! I should also mention that it was invasive ducal carcinoma with probable lymph node involvement.
