Breast Cancer Triple Negative
Sub-population of the total population of breast cancer patients.
The cancerous growth in the patients belonging to this population does not reflect the receptors of HER2, estrogen, and progesterone. Breast cancers are currently being cataloged according to the presence of these receptors
It is considered a particularly aggressive, with a very low curability index and is treated, for the most part with chemotherapy which has a response rate of only 1-2%. This cancer constitutes approx. 15% of all breast cancer cases.
The link between vitamin D and an increased risk of developing a triple negative breast cancer
Results of a comprehensive review of 13,135 women with breast cancer showed that low levels of vitamin D in the blood appeared in 88% of triple negative breast cancer, compared to only 37% in non-triple negative breast cancer patients.
Although more studies are needed to confirm this, this work certainly indicates a close link between low blood levels of vitamin D and an increased risk of developing triple negative breast cancer, a subtype of breast cancer that is more violent than other types of breast cancer.
