This study, which included 27 breast cancer survivors who performed moderate-intensity strength workouts twice per week, revealed that weightlifting appeared to help prevent swelling in the arms and chest, which are common symptoms following the surgical treatment of breast cancer. Study author Dr. Lynn Panton adds, “At one time, women were told they shouldn’t do upper-body activities after surgery and treatment because doctors thought it could actually cause swelling to become worse… But we’re finding that strength training can really help women recover from treatment and help prevent and reduce this swelling.”
