Determinants of physical activity in young adult cancer survivors
Objectives:
To examine the determinants of physical activity (PA) in young adult cancer survivors (YACS).
Methods:
A survey of 588 YACS in Alberta, Canada, assessed PA, medical and demographical factors, and theory of planned behavior variables.
Results:
Path analysis explained 38% (P<.001) of the variance in PA with significant contributions from intention, planning, affective attitude, education, and general health. In turn, 56% (P<.001) of the variance in intention was explained by perceived behavioral control, instrumental attitude, and affective attitude.
Conclusion:
PA interventions in YACS should focus on developing strong intentions by targeting perceived behavioral control, instrumental attitude, and affective attitude.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
