With the growing number of cancer survivors worldwide, it has become
increasingly important to create non-pharmacological approaches that support
long-term health and promote better survival outcomes. While physical activity
(PA) is widely recognised for its health benefits, and sedentary behaviour (SB) is
known for its detrimental effects in the general population, evidence on their
independent and especially joint associations with health-related quality of life
(HRQoL) and survival outcomes in cancer survivors has been limited. This
literature review examines findings from recent prospective cohort studies and
systematic reviews, drawing on a nationally representative sample of US cancer
survivors, as well as specific populations by cancer type. The review highlights that
both prolonged sitting and lack of leisure-time physical activity (LTPA)
independently increase mortality risks among cancer survivors. Their combined
occurrence is linked to the greatest risk of both overall and cancer-specific mortality.
At the same time, engaging in regular physical activity—even at modest levels—has
been shown to improve HRQoL, reduce cancer-related fatigue, and enhance
physical fitness in various groups of cancer survivors. The findings highlight the
importance of promoting LTPA and reducing SB as key elements of cancer
survivorship care, with meaningful implications for clinical practice and public
health guidelines.
