How can machine learning benefit the healthcare sector?

Machine learning is one aspect of the AI portfolio of capability that has been with us in various forms for decades, so it's hardly a product of science fiction. It's widely used as a means of processing high volumes of customer data to provide a better service and hence increase profits. Yet things become more complex when the technology is brought into the public sector, where many decisions can greatly affect our lives. AI is often feared, particularly around removing the human touch that could lead to unfair judgements or decisions that could cause injury, death or even the complete destruction of humanity. If we think about medical diagnoses or the unfair denial of welfare for a citizen, it's apparent where the first two fears arise.
