“…However, randomized studies have shown the substantial improvement in QoL of cancer patients due to an adequate program of physical activity [23][24][25]34] and impact the cancer survival [7], since it reduces the peak oxygen consumption, improves physical capacity, increases self-esteem, reduces accumulated stress, and promotes relaxation [8,11]. Consequently, physical activity is strongly recommended for healthy individuals to improve cardiorespiratory and muscular fitness, bone health, and in general to reduce the risk of non-communicable diseases, depression, and cognitive decline [11] The correct application of an exercise program may have a beneficial effect in onco-hematologic patients, since it may improve the function of the immune system (regulation of macrophages and natural killer cells interacting with cancer cells) [9,10] and provide a protective effect against cancer progression. In our clinical center, we encourage cancer patients, to progressively increase their physical activity, depending on their abilities and attitudes, according to the Cancer Patient Support Organizations such as the Lymphoma Action and includes walks, planned exercises, sports activities, domestic activities, and professional activities [26].…”
