While having a positive attitude in life has it's owns benefits, a latest research by Israeli scientists claimed that positive emotions can also be helpful in fighting cancer.
"Given the central role of the reward system in positive emotions, these findings introduce a physiological mechanism whereby the patient's psychological state can impact anti-tumor immunity and cancer progression," the study said.
According to the study, some immune cell subsets like Myeloid Derived Suppressor Cells (MDSCs), support tumor growth by suppressing the anti-tumor immune response and by generating a favorable environment for the tumor. MDSC is one of the regulator of the immune system's activity in the body.
After 14 days of continuous treatment, the researchers identified a 50 per cent reduction in the size of the tumors," reported The Times of Israel while quoting the study.
The scientists added that though many of similar studies have given inconsistent results and most research in this field has been done focusing negative emotional states, such as stress and depression on health but the impact of positive mental state on cancer biology is largely unknown.
