Identifying mutant genes capable of causing breast cancer

Australian scientists are getting closer to the finish line in understanding the cause of breast cancer, when it is the first time to accurately identify mutations of BRCA1 and BRCA2 genes that may be the cause of human transmission. developing the aforementioned dangerous disease.

In a study published June 21, scientists at the University of Melbourne and Peter MacCallum Cancer Center have discovered that BRCA1 and BRCA2 , which are tumor suppressor genes , once mutated are possible. The ability to significantly increase the risk of developing breast or ovarian cancer.

Women with these mutant genes are at lower risk when they are under 30 years old.

The study showed that women with BRCA1 mutation had a 72% chance of developing breast cancer until the age of 80, while the rate of developing ovarian cancer in this group was 44%. For women with BRCA2 mutation, this ratio is 69% and 17%, respectively.

The Australian scientists obtained this result based on the analysis and assessment of the health risks of 10,000 women around the world carrying the mutant gene over a period of 20 years. This is also considered to be the most successful research, because it is more accurate and convincing than long-term studies that are only done based on the results of medical records assessment.

The study also showed that women with the mutated genes are at lower risk when they are under 30 years old.

In addition, it is important that scientists want to assert that the risk of developing the disease in the same genetic gene carriers grows from the age of 50. Therefore, scientists recommend regularly. conducting a cancer screening test to detect the disease early, thus providing effective prevention and appropriate treatment.
