Published On:December 26, 2018
Researchers from Toronto published various facts in the Journal of Neuroscience after a recent study held about the side effects that are caused by a drug that is used to treat breast cancer. The side effects listed by them included memory issues, mood disturbance in short harmful results on the brain that may lead to several similar problems. The study was conducted on the drug called letrozole that is very commonly used to interfere with the production of estrogens in order to avoid the recurrence of breast cancer. The research was conducted on the marmosets of both the genders male and female, marmosets are a primate model of humans but is actually non-human. Researchers from the University of Toronto situated in Canada carried on the study for the duration of four weeks and kept a check of all the behavioral patterns that went under change after injected the drug. Eventually they noticed increased levels of anxiety and that is a very commonly found side effect among females who receive this treatment. The researchers also exclaimed that the cases of breast cancer are increasing with a rapid rate and thus we need to find out what drugs can prevent or treat the rapidly occurring form of cancer. Along with many discoveries doctors realized that letrozole also effected the neurons within the hippocampus, it is an organ in the brain and impacted in the memory loss and difficulties in remembering. The researcher also exclaimed that there will be further investigation and studied in order to understand other drugs and letrozole even more so that they can come across with the best option for the patients suffering with breast cancer. Breast cancer is turning into a bigger threat with time as it is already the most common cancer among women all over the globe specifically among the developed and high income countries as most of the cases there are detected at a very late stage.
