09:05 Breast density: What Kiwi women aren't told about their cancer risk

Are New Zealand woman missing out on key information about their risk of developing breast cancer? Some women have higher breast density than others, meaning they have a greater proportion of fibrous tissue in the breast compared to fat. That can indicate a higher risk of developing cancer, as well as making it harder to read a mammogram. In the US, it's now mandatory for breast density to be included as part of a mammography report - but New Zealand doesn't collect such data. Kathryn asks Dr Monica Saini, a senior radiologist and breast cancer expert now based in Wellington, why she believes it should be.

Tensions are rising rapidly after Iran's seizure of a British-flagged ship in the Strait of Hormuz. The foreign secretary, Jeremy Hunt, described the seizure as an act of "state piracy" which demanded appropriate action.  British Royal Marines seized an Iranian tanker off the coast of Gibraltar two weeks ago. Meanwhile, Iran says it has captured 17 spies working for the CIA and sentenced some to death. Washington and Tehran are at loggerheads over Iran's nuclear programme and tensions have been growing.

Probiotics have a number of reported health benefits ranging from improvement of gut health and function, to immune support, but according to some New Zealand researchers clinical trials need to be tightened up to make sure we can rely on their results. Gemma Laws is an assistant research fellow at the University of Otago who also used to work for a New Zealand company that develops probiotics.  She suggests standardising clinical trials and product labeling to make it easier to understand the possible benefits. She'd also like to see an on-line clinical guide to the probiotic products available in New Zealand similar to AEProbio in the US.

Gavin says a US analyst and academic has added her support to the New Zealand media's decision to minimise the coverage of the Christchurch mosque shooter's ideological beliefs. Also Gavin examines the decision by most media not to name a gas fitter before he was interviewed by police over the blast that destroyed a Christchurch home.
