i totaly understand my mom had breast cancer her tumer was 6 inches around with an aggeresion of 9 they removed the brest and her lympnodes she went through radition chemo. we were all very sad for her and she was still our back bone she had the most amazing attiude toward her cancer.she was very positive. she did not use any pain meds just weed and she says if it wernt for weed she dosent kno what she would have done.just keep her smileing and thinking positive and dont let her get all stond and sleepy on pain meds caus thats were shell just lie ther and be depressed and thats not the way to beat cancer.you must keep her moving and happy and keep positive.the ons that lie there all stond up on pain meds felling sorry for themselves and constinly wanting pitty are the ons that dont beat cancer.YOU MUST BE POSITIVE NO MATTER WHAT! weed will helpm with nasia and help her eat and keep her happy. best of luck
