High age often results in loss of muscle mass (sarcopenia) as illustrated in the left panel.  Cancer is also often associated with loss of muscle mass (cancer cachexia) resulting in pronounced weakness and ultimately in death (right panel).  Other conditions resulting in muscle wasting […] - [Publications](https://www.per-olofhasselgren.com/publications/): Per-Olof Hasselgren • Research Publications   2020s Hasselgren PO.
