Can simple breathing exercises boost health for cancer patients?

This study is testing whether adding a special breathing exercise routine to standard physical therapy can improve heart and lung health in people with multiple myeloma, a type of blood cancer. Twenty-six patients currently receiving treatment will be split into two groups: one doing physical therapy alone, and another doing physical therapy plus daily breathing exercises at home. Researchers will measure heart rate and other health markers before, during, and after the 6-week program to see if the breathing exercises make a difference.
