My mum dies of cancer and I remember that the chemo and radiotherapy were horrific. I am glad that she tried them but she always said that she would rather die than go through treatment again.
I know someone who's wife is also suffering immensely due to chemo. It just seems odd that the drug kills non-cancerous cells too. I believe that one needs a strong immune system to fight cancer but chemo and radiotherapy seem to weaken the body.
OK they are our best chance atm but I do hope that someone invents something mopre cell specific soon.
