Not wanting to eat protein may be early herald of cancer cachexia

A majority of people with advanced cancers endure cachexia, a muscle-, fat-, and organ-wasting condition that is currently incurable and can be life-threatening. Detecting and intervening early can slow progression, but poor understanding of how cachexia first arises in the body makes it difficult for doctors to identify the warning signs of impending wasting other than an overall loss of appetite (anorexia).

Molecular subtypes of human skeletal muscle in cancer cachexia - Nature

Unbiased clustering analysis of the skeletal muscle RNAome in patients with cancer identifies two molecular subtypes, one of which distinguishes individuals with cachexia and indicates potential target pathways for future research.

Cancer Cachexia: Liver Identified as Driver of Body Wasting

Muscle weakness in cancer survivors may be caused by treatable weakness in blood vessels – new research

Many cancer survivors struggle with muscle weakness, which can be so profound that they may have difficulties walking up a couple of flights of stairs or going shopping for groceries on their own.

Keto diet in cancer: A double-edged sword?

The ketogenic diet—on its own—may accelerate cachexia, a disease that leads to weight loss and muscle wasting, in cancer patients, a mice study finds.
