The influence of reproductive factors on breast cancer risk in women with pathogenic mutations.

CONCLUSIONS: Breastfeeding represents a protective mechanism only in patients without genetic breast cancer predisposing mutations. Environmental and reproductive factors can impact the risk and the age of onset of breast cancer in patients carrying pathogenic mutations, but the mechanisms of action are not fully understood.

This study evaluated the association between BRCA mutation status and serum anti-Müllerian hormone (AMH) level in young, reproductive-aged patients with breast cancer. Materials and Methods: Patients ≤ 40 years of age with breast cancer and who had known BRCA status and baseline serum AMH level at Samsung Medical Center, Seoul, Korea, were considered for inclusion. A total of 52 BRCA mutation carriers (27 BRCA1 and 25 BRCA2) and 264 non-carriers were selected for analyses. The serum level of AMH was compared according to presence of a BRCA mutation, and linear and logistic regression analyses were performed to eva...

Conclusions We concluded that different races/ethnicities had different breast cancer related reproductive risk factors. Non-Hispanic Caucasians had the most breast cancer related reproductive risk factors, while the minorities had none or few breast cancer related reproductive risk factors and among these few factors only 1 was also risk factor for non-Hispanic Caucasians.

Breast cancer is the most frequent cancer among women especially in the Western world where, despite improved survival, it is one of the leading causes of death (1). Furthermore, for several decades there has been an increase in incidence, though recently there seems to be a stabilization in risk or even a small decline in typical high-risk areas such as Europe and the USA but at the same time a steep increase in typical low-risk societies such as Japan (2). Breast cancer is often regarded as a singular disease, but recent discoveries are pointing to a variety of types of potentially different etiology. Thus, the female...

Estetrol, a fetal selective estrogen receptor modulator, acts on the vagina of mice through nuclear ERα activation. Am J Pathol. 2017 Aug 18;: Authors: Benoit T, Valera MC, Fontaine C, Buscato M, Lenfant F, Raymond-Letron I, Tremollieres F, Soulie M, Foidart JM, Game X, Arnal JF Abstract The genito-urinary syndrome of menopause has a negative impact on quality of life of postmenopausal women. The treatment of vulvo-vaginal atrophy (VVA) includes administration of estrogens. However, oral estrogen treatment is controversial due to its potential risks on venous thrombosis and breast cancer.

The genito-urinary syndrome of menopause has a negative impact on quality of life of postmenopausal women. The treatment of vulvo-vaginal atrophy (VVA) includes administration of estrogens. However, oral estrogen treatment is controversial due to its potential risks on venous thrombosis and breast cancer. Estetrol (E4) is a natural estrogen synthesized exclusively during pregnancy by the human fetal liver and initially considered as a weak estrogen. However, E4 was recently evaluated in a phase I-II clinical studies and found to act as an oral contraceptive in combination with a progestin, without increasing the level of coagulation factors.

The relative frequency of malignant disease varies with sex, age, race and geographic location. The frequency differs among the developed and developing countries. A review of the first 5000 histologically confirmed malignancies seen at the Riyadh Armed Forces Hospital Oncology Department confirmed differences from those encountered elsewhere. With the absence of a National Cancer Registry, only relative frequencies can be reported. In this series, gastrointestinal tract cancers were the most frequent, at nearly 18%, with high relative frequency of cancers of the liver and esophagus. Colorectal malignancies were less frequ...

CONCLUSION: Implementing targeted screening programs of breast cancer for younger women may become a need in the future. Meanwhile, well-education on risks of breast cancer and regular self-examination for early diagnosis need to be emphasized for the prevention of breast cancer and related diseases in young ages.

In this month’s article, I explore issues relating to the health of women in emerging markets. I will recommend that pharma companies wishing to maximize the opportunity in women’s health need to start from an understanding of how women are viewed by society in these markets and challenge awareness, attitudes and access barriers that can lead to their health outcomes being sub-optimal. As a starting point, it is necessary to establish a working definition of women’s health.  This isn’t as straightforward as it might seem, as women’s health can be considered at multiple levels.  The c...
