Sister recently diagnosed

Hi, New to this forum but my sister has found it and is finding it a life saver! My sister has recently been diagnosed with Stage 2b cervical cancer. Has just been given her 5 week treatment plan just waiting on a PET scan. Will be having radiotherapy and chemotherapy and then also Brachytherapy. I guess what Iā€™m searching for on this forum is what can we do as a family to support her. Looking for any advice/helpful tips to help her get through the next few months and beyond. Thanks :pray:
