My mum (69) has breast cancer for the past 5 years and on 2 previous occasions prior to that. It has now  spread to her lungs. It can't be cured but has treatment every 3 weeks and so far has only moved a little. Since last November she has been having high temperature, infections (chest and urinary and has lost around 3 stone, as well as muscle mass loss. She is exhausted just going upstairs.. no one seems to say anything about her weight and muscle loss but it is so dramatic and she looks amaciated despite a good appetite.. it is so hard to see her struggle.. anyone else out there seen this happen with their loved ones?
