Firefighting's forever chemical legacy

<description>&lt;p&gt;Anne Dyer is a trailblazer - becoming the first female Bishop in the Scottish Episcopal Church when she was appointed more than seven years ago.

<description>&lt;p&gt;File on 4 Investigates discovers a world of lies and blame within adoption in the UK. The BBC has conducted the most extensive Freedom of Information request ever into adoptions that have broken down, finding that more than 1,000 adopted children in the UK have returned to care in the past five years. That is much higher than the figure in a recent government report - but the true number is likely to be even larger, as only a third of authorities said they collected this data as standard practice. Some adoptive parents say they’ve been given so little support that they’ve been forced to return their children to the care system. &lt;/p&gt;&lt;p&gt;This programme explores the scale of the crisis as we hear from parents pushed to the limit, a teenager returned to care and a social worker giving a rare view of the system from the inside.&lt;/p&gt;&lt;p&gt;Producer: Ashley Kennedy &amp;amp; Claire Kendall

Adoption: The Blame Game

<description>&lt;p&gt;Multi cancer detection tests or MCDs can detect many cancers through a simple blood test. Many detect fragments of cancerous DNA that have broken off a tumour and are circulating in the blood. They can often then identify where the cancer may be.
 
The NHS is currently involved in the words largest trial of one such test. The Galleri test is made by US firm Grail and the company says its mission is to detect cancer early when it can be cured. Heavyweight investors include Jeff Bezos and Bill Gates.&lt;/p&gt;&lt;p&gt;More than 140,000 volunteers took part in the trial and the results will be known next year. If successful, the test may be rolled out further. &lt;/p&gt;&lt;p&gt;File on 4 Investigates looks at how effective such tests are and whether the trial will show it can save lives.&lt;/p&gt;&lt;p&gt;Medical journalist Deb Cohen speaks to one woman whose cancer was found by the test and successfully treated.

Multi-Cancer Testing - Hype or Hope?
