In 1928, Showa University founded the University Hospital; it has provided high quality medical education for a long time. Subsequently, several affiliated hospitals were established with various functions to meet the needs of the local community. Following a unique conception, these hospitals aim towards a true medical education involving neighboring fields such as pharmaceutics, dentistry, and nursing. The role of Showa University affiliated hospitals has steadily increased in importance in an era of transition in Japan.

Re: Angelina Jolie’s double mastectomy and the question of who owns our genes2 June 2013It is estimated that at least 60% of the world’s 7 billion people are Asians, but yet less than 5% of the known BRCA carriers that have been identified are Asians [1]. In order to share knowledge of and improve the quality of hereditary breast and ovarian cancer patients in Asia, we have established the Asian BRCA consortium in October 2011. The consortium has members in 12 Asian countries and welcomes new members with a shared vision of collaborating for research in Asia. We urgently need to advocate for change in the legal protection against genetic discrimination, and to advocate that governments should at least pay for testing fees, surveillance and risk reducing strategies so that we are able to offer the best strategies for BRCA carriers regardless of where they live.Authors: ABRCA Consortium1.
