I’ve been diagnosed with breast cancer three years ago, and after complete mastectomy and radiation the cancer was gone - i was lucky it was caught in stage I. All my check-ups with oncologist since then have been ‘all clear’, but my mind is not at all at rest, especially since I’ve started experiencing almost constant left shoulder pain (and my left breast was where the cancer was first found) for the last few months. I don’t have an appointment with an oncologist until June, so if anyone could help me with advice if I should call up the oncologist’s office and schedule the appointment sooner, or is this shoulder pain completely unrelated to breast cancer?
