Cancer's exploits are titillated by personality traits, contemplates a new school of thought, after experiments conducted on unwitting rodents. The idea that personality types may increase the susceptibility to cancer is the cornerstone of this research.
Researchers at the University of Chicago have said that timid rats provided the right entry point for cancer as compared to the rats that portrayed an adventurous nature. The findings leave a clue of such occurrences in humans as well, which would need to be researched further.
AdvertisementFor this study, the Chicago group chose a class of rodents that were vulnerable to breast and pituitary tumors. Female rats which were anxious and frightened by nature succumbed to breast and pituitary cancer, as compared to aggressive and bold rats. The timid rats also experienced irregular reproductive cycles than the rats made of sterner stuff. The interruption in the reproductive cycle could trigger hormone imbalances, which might be one important reason for the development of cancer at an earlier age, the researchers conjectured.
The average life span of the timid rats was 573 days, compared to 850 for the brave ones.
