A s a cancer survivorship researcher, I have been wondering for 2 decades about the use and misuse of the concept of cancer survivor. "Controversies in defining cancer survivorship" have been raised before. 1,2 This editorial is based on a recent experience after conducting a scoping review on the use of telehealth in cancer survivorship and struggling to find articles that distinguish between cancer patients in treatment and cancer survivors after treatment was completed.The first definition of the concept of cancer survival was in 1985 by Mullan, 3 a physician and cancer survivor, who presented the 3 "seasons of survival" that included acute survival (period after the diagnosis, where the focus is on surviving treatment), extended survival (period after the end of treatment, often known as remission, where the focus is on dealing with the short-term consequences of treatment), and permanent survival that refers to long-term survival (5 years after the end of treatment, when the patient is "cured" but needs to deal with the late effects of treatment). 3 Today, 5-year survival for all patients with cancer has increased because of advances in cancer screening and effective cancer treatment, although differences exist between types of cancer and stage at diagnosis. 4 Worldwide, there are more than 32 million cancer survivors, and this number is projected to increase in the following decades. 4 Certainly, we should acknowledge the survival statistics of cancer if health management is to be effective. However, we also should focus on the concept of cancer survival that is practical in the real-world setting.Here is where the problem lies. Many researchers and institutions used interchangeably the term cancer survivor to refer to anyone who received a diagnosis of cancer no matter where they are in the course of the illness. 5 I agree on the importance of having a holistic perspective of the cancer trajectory. However, this approach limits the understanding of a cancer survivor as a person who has completed treatment, is disease free, and may be dealing with the challenges associated with cancer survivorship, including chronic pain, fatigue, chemobrain, organ toxicity, depression, fear of recurrence, financial toxicity, and insurance problems, among others. 3 Furthermore, it is important to distinguish between short-term and long-term cancer survivors to help ensure healthcare services are better tailored to suit their needs. "Short-term survivor" refers to the person who finished treatment 1 to 5 years ago and is in remission with no signs and symptoms of cancer (the extended survival according to Mullan). "Long-term survivor" refers to the person who completed treatment 5 or more years ago (the permanent survival according to Mullan). 6 Why is it important to make time distinction when referring to cancer survivors? The answer is both simple and complex: to enable practitioners, researchers, managers, and policymakers to meet the specific [physical, psychological, social, spiritual, financial] needs of survivors aft...
