Risks and protective factors for triple negative breast cancer with a focus on micronutrients and infections
Abstract
Triple negative breast cancer (TNBC) is an aggressive form of breast cancer (BC) with a poor prognosis. Second, patients cannot benefit from targeted therapy, except for those with BRCA1/2 mutations, for whom poly (ADP-ribose) polymerase (PARP) inhibition therapy using olaparib has recently been approved. As global priorities continue to be epidemiological analysis of BC risk factors and early diagnosis, this review focuses on the risks and protective factors associated with TNBC. A PubMed keyword search for new knowledge on the risks and protective factors for TNBC was carried out. We also found statistical information from current online databases concerning the estimated incidence, prevalence and mortality worldwide of this cancer. Traditional risk factors for BC and TNBC are those related to reproduction such as the age of menarche, age of first birth, parity, breastfeeding and age at menopause. Attention needs to be paid to familial BC, weight control, alcohol consumption and regular physical activity. Epidemiological studies on TNBC provide evidence for protective factors such as regular consumption of soya, seafood, green tea, folic acid and vitamin D. Potential risk factors may include night work and viral infectious ag...Continue Reading

Breast Cancer Triple-N
Breast cancer cells have receptors for estrogen, progesterone, HER2 receptors (also called ERBB2). Triple-negative breast cancers do not have any of these receptors. Here are the latest discoveries pertaining to triple-negative breast cancers.
Breast Cancer: BRCA1 & BRCA2
Mutations involving BRCA1, found on chromosome 17, and BRCA2, found on chromosome 13, increase the risk for specific cancers, such as breast cancer. Discover the last research on breast cancer BRCA1 and BRCA2 here.
