Hi JesseBear
sorry I cant help you with that particular cancer (I've not heard of it) - but I can help you with breast cancer. I was diagnosed 2 years ago and had a mastectomy with full axilla clearance (all lymph nodes removed in underarm and arm as all were cancerous). My initial diagnosis was advanced breast cancer with widespread bony mets (which just means that the cancer has already spread throughout my skeleton - most bones being affected).
Chemo is certainly not the easiest of treatments, but there are drugs that are given to the patients to help combat nausea, etc. Your mum will feel like she has been hit with a Mack truck, the tiredness is 'all consuming' and the emotions 'run riot' - but she will get through it. I used to tell myself that if the chemo was making me feel sick - just imagine what it was doing to the nasty little cancer cells!!
Radiation affects people differently and also depends on the radiation strength - again she will be extremely tired and she may have skin discomfort or some burning - dont be alarmed the radiation staff are wonderful and they have lots of hints and creams for the skin.
I dont want to detract from this site, but there is also the bcna website (just Google it) which is specifically for Breast Cancer. You may find this extremely helpful - Mind you, in having said that, there are wonderful people on this site too.
It's natural for your mum and you to feel overwhelmed, we all do, regardless of what type of cancer we have. Things will settle down eventually and you will find that if you just 'go with flow' you both will get through this.
I hope all goes well.
Di 🙂
