Many individuals are delaying investigations into potential cancer symptoms, a new survey suggests, often due to difficulties securing GP appointments or underestimating the seriousness of their health concerns.
Research by Cancer Research UK, polling 6,844 individuals across the UK via YouGov, found that 53 per cent anticipated trouble booking a GP slot, 47 per cent actually encountered issues, 44 per cent assumed symptoms were not serious, and 43 per cent believed they could manage them independently.
In light of these findings, Megan Winter, health information manager at Cancer Research UK, emphasises that any unexplained change should be flagged to your GP.
“Our message is that you need to get everything checked out if it’s not normal for you because there are so many different signs and symptoms of cancer and they can manifest differently for different people,” says Winter. “Listen to your body and if you notice something unusual that doesn’t feel right, talk to your doctor.”
Here are eight signs that should always be evaluated by a professional.
1) Unusual lump or swelling
“If you’ve noticed any unusual lump or swelling anywhere on the body, that is something that you should get checked out by a GP,” advises Winter.

2) Unexplained weight loss or tiredness
“Some of the more general symptoms of cancer that can affect the whole body are unexplained weight loss or tiredness,” says Winter. “For example, if you’re losing weight without trying, that’s something to talk to your doctor about.”
3) Unexplained bruising
“Unexplained bruising can be another more general symptom,” says Winter. “For example, if you are bruising more easily, but you haven’t hurt yourself.”
4) Change in bowel habits
“If you’ve noticed a change in your bowel habits, such as you’re constipated more or are pooing more than normal, that’s something to talk to your GP about,” says Winter. “In addition, blood in your poo or wee, or unexplained bleeding from your vagina in between periods and after sex is also something to flag.”
5) Breathlessness
“If you are feeling breathless doing your usual day-to-day activities, like doing housework and feeling breathless for no apparent reason, then that’s something to flag up with your GP,” says Winter.
6) Persistent cough

7) Unexplained pain
As we get older, it’s more common to experience aches and pains, but any unexplained or persistent pain anywhere in the body could be a sign of something more serious, highlights the health information manager.
8) Skin changes
“If you’ve noticed any changes to an area of skin – for example, you have an area of skin that’s perhaps isn’t not healing – get that checked out by a doctor,” advises Winter. “A detailed list of specific symptoms of melanoma skin cancer can be found on Cancer Research UK’s website.”
Who should you go to first?
Your GP should always be your first port of call about any health concerns.
“We often hear from people that it’s difficult to get an appointment with their GP, but it’s important to keep persisting,” says Winter. “There’s lots of different ways that you can contact your GP now, including over the phone, online, or by popping into your GP surgery.
“It’s not the public’s job to know what’s wrong with them, that’s what the doctor is there for, so you won’t be wasting their time by bringing these concerns to them.”
Why is it important to flag these symptoms early?
“It’s important to flag any symptoms early because cancer that’s diagnosed at an early stage is more likely to be treated successfully,” says Winter. “When a cancer is smaller and hasn’t spread, there’s more treatment options and it’s more likely to be treated successfully.
“If you can listen to your body and talk to your doctor about any change, that can make all the difference in terms of outcomes. In most cases, it’s not going to be cancer, but if it is, spotting it early makes all the difference.”
