Introduction:
Anemia is one of the most common hematological manifestations occurring in cancer patients, related to a poorer prognosis. Among supportive care in cancer, exercise is emerging as a crucial tool demonstrating reduction in mortality risk and counteracting several diseases and treatment-related adverse events. Nevertheless, the effect of exercise on anemia in cancer is still a relatively unexplored area.
Area Covered:
Six studies investigated the impact of exercise on anemia trajectory in cancer patients, with intriguing results. The potential mechanisms by which exercise may modulate the blood system are heterogenous, including bone marrow stimulation, improvements in the hematopoietic microenvironment, and control of both inflammation and hormone levels. Although training and/or living at high altitudes is a recognized method to increase erythropoiesis, the effect of a hypoxic external environment on tumor progression should be clarified before considering this strategy in cancer patients.
Expert Opinion:
Although the available investigations of exercise in anemic patients with cancer are few, exercise emerges as an important supportive oncological care capable of assisting patients in maintaining their autonomy. Our special report offers several suggestions to address future research in this field and determine the real contribution of an active lifestyle on this condition.

01:24Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
