Breast Cancer

Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

HER-2 Positive Breast Cancer

Human epidermal growth factor receptor 2 (HER2) is a gene that can play an important role in the development of some types of breast cancer. This gene is also sometimes referred to as Erc-B2 receptor tyrosine kinase 2 (ERBB2). This gene is involved in the production of HER2 proteins, which are present on breast cells as receptors to control the growth, division, and repair of the cells.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

Friends play a direct role in encouraging regular cancer screening

Friends may play a direct role in whether people keep up with cancer screening regularly, while family influence appears to operate more through knowledge and attitudes towards screening, according to new research by Singapore Management University's (SMU) Center for Research on Successful Ageing (ROSA).

Dual-targeted therapy shows promise against metastatic triple-negative breast cancer

A new preclinical study suggests that attacking triple-negative breast cancer (TNBC) in two ways at once can kill cancer cells, slow tumor growth and limit the cancer's spread. Researchers at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) developed the approach.

Rice, fish and pickles: Is the traditional Japanese diet as healthy as we think?

A systematic review of 37 studies found that greater adherence to predefined Japanese-style dietary patterns was associated with lower all-cause and cardiovascular mortality, based on pooled evidence from three cohort studies. However, health associations varied according to dietary composition, suggesting that traditional Japanese diet scores alone may not adequately distinguish the potential benefits and risks of different food combinations.
