Cancer affects those diagnosed with it but it also affects the caregivers of those individuals. In my years practicing oncology I have learned that the caregiver is equally, although sometimes differently, impacted. One thing I love about practicing oncology is that I often get to know patients’ caregivers as well as the patient. I asked one of my patient’s sisters to put into writing how her sister’s diagnosis has impacted her. Her words, written below, are poignant and I think will strike a cord with caregivers, who can relate to the ways in which cancer has impacted her.
