Contacting your GP
One in 10 people would not contact their GP even if they had a lump or a new mole which did not go away after a week, the survey found.
Another third of people would worry about seeking help, according to polling carried out by Portland.
Getting coronavirus or giving it to their family were among the top reasons that people would not come forward when they have cancer symptoms along with fears that they could be a burden to the health service.
Waiting to get help could have serious consequences for patients and put a greater burden on the NHS, Prof Johnson said.
Online consultations mean people do not necessarily need to go to GP surgeries for check-ups while COVID-free cancer hubs have been set up to provide surgery along with independent sector hospitals who have signed an unprecedented deal with the NHS.
Virus protected hubs are up and running in 19 areas of the country to date so people can have their operation safely with thousands of patients already having treatment through a hub.
"Don't put it off"
Lynda Thomas, Chief Executive at Macmillan Cancer Support, said:
“We urge you not to put it off, and don’t think you’re not a priority during coronavirus. Safeguard your own health and get any concerns checked out. Not diagnosing and treating many cancers fast makes treatment harder and can reduce the chance of survival.”
