I am now even more confused as when my friend told me they had metastatic cancer I presumed the reason I had noticed them deteriorate so much in the past two months was due to the cancer, but they have just told me they had radiation treatment in 2018 and that the cancer is slow growing and stable, so I am guessing it can't be that?

Even since I posted this just over a week ago they have continued to go downhill and are sleeping even more and eating even less and are on Zomorph due to pain and even walking a short distance around the house exhausts them.

He has been having numerous blood tests and scans over the past two weeks and an X-Ray showed what the doctor called puffy/fluffy bones - so on Monday he had a bone scan. The doctor mentioned a drug they could use to treat it and I looked it up and it was a cancer drug, so I am presuming that the likelihood is the cancer has spread to his bones.

He has lost two stone in two months - around 15% of his bodyweight and with no appetite I can't see him regaining that anytime soon, has definitely lost muscle and has chronic anemia (he has an emergency blood transfusion a week ago and for a day he felt better - but then a couple of days later he was even worse than he was before).

Could this still be cachexia even though his cancer is stable and all seems good there?
