'Our results suggest that the simple strength home exercise program may effectively contribute to cancer prevention in combination with supplemental omega-3s and also in combination with both supplemental omega-3s and vitamin D,' the study’s authors added. They also pointed out that three years may be too short when talking about cancer prevention. Researchers said the number of participants may be considered small. 'We saw a cancer risk reduction when all three interventions were combined,' the study’s authors noted. The risk was a bit higher for those who were assigned to two out of the three steps. Researchers said the health risk for cancer was very low among the participants who took vitamin D, omega-3 and exercised.
