Smartphone apps that test for skin cancer are inaccurate and could lead to preventable deaths, scientists from Queen Mary University of London.
The researchers found that two apps for detecting skin cancer – unnamed for legal reasons – identified rare and aggressive cancers as low risk.
Based on user photos, apps alert if they identify a possible sign of skin cancer, such as unusual moles or discolored spots.
Research has shown that the apps, which claim a detection rate of 95%, classify up to one-fifth of certain cancers as benign rather than malignant, such as amelanotic melanoma and Merkel cell carcinoma.

Easy aches blackcurrant
According to a study, black currants may relieve sore muscles after training.
Research from the University of Surrey has shown that black currant concentrate halved muscle pain in those who frequently exercised vigorously.
The study involved men and women undergoing intensive exercise for eight days, including movements to build muscle, known as resistance training.
Half of the participants took a 300 mg capsule of black currant concentrate each day, while half did not. They then assessed their muscle pain over four days. The blackcurrant group saw their muscle pain decrease three times faster than those who did not take the pill.
Scientists say the “marked” improvement is due to the fact that black currant is rich in anthocyanins, a natural compound that reduces inflammation.
Stigma against people with schizophrenia is rife, according to a survey. Almost half of the 1,500 respondents to a national survey would not let someone with schizophrenia look after their children.
A third wouldn’t want a schizophrenic to be a doctor, and a tenth wouldn’t want them as a friend or neighbor, according to the survey for the Esomar charitable foundation.
Schizophrenia is a serious, long-term mental health problem in which people with schizophrenia find it difficult to distinguish their own thoughts from reality.
However, patients receiving treatment – drugs and psychological therapy – are able to live healthy and stable lives.
Doctors can now diagnose life-threatening brain and head injuries at the bedside with Swoop, the UK’s first portable MRI scanner.
Usually MRI scanners, which use magnetic fields and radio waves to create detailed images that can show tumors or traumatic brain injury, are so large that they need their own dedicated rooms.
Dr Khan Siddiqui, of the medical technology company Hyperfine behind Swoop, which produces a lower level of radiation than large MRI scanners, says patients can get a scan result in 90 minutes.
