It has been found that saturated fatty acids may cause malingnant mammary gland tumors in females who happen to be in the postmenopausal stage of their lives.
The presence of fatty acids in the mammary glands of women may be an indication of cancer risk. This is especially so if the females have covered the menopause phase in their lives.

The study was published in the journal Radiology recently. These findings may help scientists pick up clues as to what causes breast cancer among females.
Fat has a large role in the etiology of breast cancer. BMI and fat intake in the diet both matter in the long run for females. BMI in particular seems to play a crucial role.
In premenopausal women, it has a protective effect. Yet in postmenopausal women, it increases the chances of contracting breast cancer. The rationale behind this biochemical sequence remains a mystery to most researchers.
Some say that the production of the female hormone, estrogen as well as adipokines are responsible for the nasty results of fat intake. Adipokines give the go ahead signal to proteins that are a secretion of adipose tissue.
Breast fat seems to have a significant role in the development of tumors. A new MRI (magnetic resonance imaging) method was developed at a medical center in NYU.
It is termed gradient-echo spectroscopic imaging. It measures various types of fat in breast tissue. The study involved 89 patients. The BMI of each subject was noted at the beginning.
58 women were premenopausal and 31 were postmenopausal. 49 of the females had benign breast tissue, 12 had ductal carcinoma in situ and 28 had invasive ductal carcinoma.
The results showed that more saturated fatty acids and less monounsaturated fatty acids were present in the breast tissue of postmenopausal women with invasive ductal carcinoma.
Also in the women with benign breast tissue, the postmenopausal women had higher polyunsaturated fatty acids and lower saturated fatty acids than the premenopausal women.
These findings speak for themselves. Thus BMI and fatty acids in breasts had no correlation whatsoever. It is the type of fat in the breast tissue that determines the outcome of a benign or malignant tumor.

The research on the matter is still not complete. Sometime in the future, breast cancer will have been conquered and females will be free of this scourge that haunts their lives in the present times.
