<p>Clinical experience shows us that many of the patients that we see in our clinics present with comorbidities: pain, numbness, a range of motion limitations, reduced joint movement, functional problems, etc. I am part of a group that is conducting a multisite Canadian study, aiming to chart the incidence and course of three types of arm morbidity — pain, range of motion (ROM) restrictions and lymphoedema — in 750 women during the first five years following breast cancer surgery. Members of our group had already raised the question of arm morbidity and its importance (Hack et al, 1999; Kwan et al, 2002). As with any research, we answer a few questions and our eyes are opened to many more.</p>
