‘Reward-system plays an essential role in positive emotions which can help fight cancer.’
The scientists explored the possibility of the brain's reward system fighting the tumor in mice. Some immune cell subset like Myeloid-Derived Suppressor Cells (MDSCs)

50 Percent Reduction in the size of the tumors was observed
after 14 days of continuous treatment.
The impact of positive thinking is unknown because most of the earlier studies focused on the negative emotions like stress and depression.
