-Health related quality of life (HRQOL).	- Value of Upper Limb Lymphedema 27 (ULL-27), specific instrument for patients with Breast Cancer-Related Arm Lymphedema, transculturally adapted and validated in its Spanish version in 2016 [48]. (The result is calculated as a percentage of social, physical and psychological dimensions in which the higher the result obtained, the greater the disability or symptom/poorer the HRQOL). - Health Questionnaire EQ-5D-5L by EuroQol Group, generic and standardized instrument used to describe and value the HRQOL of a group or population and validated in Spain by Badia X. et al. in 1999 [49].
