I think the chemo, whilst making your friend feel poorly, shrinks the tumor and therefore is a less invasive operation. (Don't quote me) My mum has had breast cancer, which leads to 'secondary' ones and she has back and stomach and is currently awaiting outcomes on x-rays.. but she doesn't tell me everything as she thinks I'm better off not knowing - which by the way I'm not as my sister, who lives near her (I'm 200 miles away) gets chapter and verse and then spills to me, making me feel useless being so far away - anyhoo - end of non-uplifting thread!! Sorry....
