Morrisons is adding labels in boxer shorts and bras urging buyers to contact their GP if they notice possible signs of breast or testicular cancer.

Packaging will feature QR codes that can be scanned using a phone to access further advice online.

Men’s boxers and crop top bras sold by the supermarket in its own-brand Nutmeg range will carry the first set of labels.

NHS guidance about early symptoms including changes to the look and shape of breasts or painless swellings in testicles will be accompanied by a QR code linking customers to more detailed information on the NHS website.

“This is the first time the whole of the NHS has worked with a national supermarket brand to put health messaging on clothing, with the aim of encouraging thousands more people to be body aware, so they can spot new or unexplained changes that might be cancer symptoms early,” said NHS England’s national director for cancer Cally Palmer.

The NHS chief said overall cancer survival rates were at an all-time high but stressed that the earlier the disease is detected the higher the chances of successful treatment.

The UK government said last week that cancer treatment targets in England would be streamlined from October with the objective of diagnosing and treating patients’ cancer faster.

The new strategy aims to diagnose 75 percent of people at an early stage.

Some cancer charities welcomed the treatment shake-up but others warned steps still need to be taken to tackle the country’s “current disastrous cancer performance”.

Oncologist Pat Price, co-founder of the #The CatchUpWithCancer campaign said the target needed to be 95 percent not 75 percent.

“The only measure that will ‘move the dial’ is the development and implementation of a radical new plan backed up with smart investment in people and kit,” she stated.

Research published last month by the Swedish Institute for Health Economics found cancer survival rates in the UK lagged behind those of other European countries.
