Catching cancer early – how people make decisions about their symptoms and seeking help from their GP
By Susanne F Meisel, on 26 January 2015
Catching cancer early is important because it gives a better chance of survival. Although the UK has one of the best heatlhcare systems in the world, it still does worse for cancer survival one year after diagnosis than other countries with a similar standard of care. One reason for this is that cancer is often found at a later stage, and is therefore more difficult to treat.
Researchers are trying to work out what contributes to a late cancer diagnosis. One factor could be delays in the time it takes the GP to refer a patient to see a specialist. This is why guidelines have been developed to make sure that patients are seen within a reasonable time period . However, for the GP to make a referral, the patient has to present with a symptom in the first place. For that to happen, people need to recognise their symptoms as serious enough to make an appointment to get it checked out. A big part of our research at the HBRC tries to find out what factors stop people from going and seeing their GP when they have symptoms that might be signs of cancer.
In studieswhere people are specifically asked about cancer and cancer symptoms, they are usually pretty good at listing at least a few. They are even better if the symptoms are already listed and they just have to recognize them as potential signs of cancer. However, in studies where cancer patients have been asked about what led to their diagnosis, many have said that they did not recognise their symptom as a sign of cancer at first and therefore saw no need to go and see the GP; although fear of a cancer diagnosis was also sometimes mentioned as a reason not to go and see a GP .
This shows that, as often, the research studies may not actually reflect what happens in the ‘real world’. Given that many cancers have quite varied symptoms that could be due to lots of causes, such as bloating, change in bowel habits, unexplained bleeding or a persistent cough, it is not surprising that many people may not link these to something as serious as cancer. Others, such as lumps, may be more recognisable.
It appeared that once people had thought about cancer, they could tell which symptoms were related. However, our researchers tried to find out whether people would think of cancer as a potential cause for a symptom without any prior prompting.
This study was part of a larger survey study, where people answered lots of questions about their health, including any symptoms that would not go away within the last three months. Our researchers were especially interested in responses of people who were over the age of 50. This was because cancer risk goes up with age. Therefore, it is more likely that symptoms are caused by cancer.
Our researchers selected 48 men and women of different ages, ethnicities and social backgrounds who had agreed to be interviewed. They were asked to describe the experience of their symptoms, why they thought it was happening, who they had asked for advice and what they had done about it. Crucially, cancer was never mentioned, to make sure that people would not be set up to think about it. However, the researchers would point out to people that they should get their symptoms checked after the interview.
Only about half of the people interviewed had seen the GP about a symptom. People were most likely to seek help from the GP when they had persistent bleeding. Fewer people sought help for a sore that does not heal or a persistent cough. People sought help because they thought that a symptom was serious, out of the ordinary, and because they had a ‘gut-instinct’ that something wasn’t right. Often, they also mentioned that they had talked about their symptoms to friends and relatives, and that they had encouraged them to see a GP. For example, one participant described how his persistent coughing woke up his wife who told him to go and do something about it. However, how people defined ‘persistent’ varied a lot – sometimes they had a symptom for many years, before they went and sought help for it. People also went to the GP once they had thought about cancer as a possible cause for their symptom. For example, they saw cancer awareness campaigns, which then made them realise that their symptom may be serious.
People who did not seek help for their symptom thought that it was nothing serious. Often they just attributed it to getting older, and there was an assumption that the body wasn’t as good at repairing itself. Many also had a stoic attitude (“stiff upper lip”) to their symptom, and there was a perception that going to see the doctor would be a sign of weakness, and that they would be seen as ‘timewasters’. This attitude often led people to tolerate quite severe symptoms, such as severe diarrhoea, or visible lumps. To a lesser extent, some had negative attitudes towards the healthcare system, and did not believe that the doctors could do anything about their symptom.
Interestingly, the findings did not differ between men and women and between people from different social backgrounds; although this might have been because we only asked a small number of people about their opinions.
This study thus offers some potential explanations for UK’s struggle with early detection of cancer. Cultural norms (‘stiff upper lip’), lack of knowledge about symptoms, putting symptoms down to old age, as well as fear of a cancer diagnosis, are all contributing factors. It is important to continue making people aware about the warning signs of cancer. The recent campaigns by the major cancer charities therefore seem to be on the right track. It may also be important for GPs to encourage their patients to come and see them if a symptom doesn’t go away, to counteract concerns by patients that they may be seen as ‘timewasters’. This may be especially true for the elderly, who may be more prone to avoid medical care unless absolutely necessary.
