Today, lung cancer is the third most common cancer in the UK. Cases peaked in the 1980s and have been decreasing slowly since then thanks to recent advances in the management of lung cancer. How has the government helped the fight against lung cancer in Britain? Let's find out!
The meaning of lung cancer is that it is a disease that affects the lungs when cells abnormally divide to form tumours. There are different causes of lung cancer, but many cases are preventable.
Lung cancer is a result of mutating cells forming tumours and can affect anyone. However, certain factors and lifestyle choices can increase the risk of lung cancer. Let's look at some causes of lung cancer.
These reasons demonstrate how physical and environmental factors can increase the risk of lung cancer. Reducing exposure to these causes can help the fight against lung cancer in the UK.
Public health challenges with lung cancer are often associated with the economic costs of limiting the causes. Dangerous chemicals, poor air quality, and smoking are the top 3 preventable causes of lung cancer, and yet they are the result of beneficial economic development in the UK. Let's find out the difficulties with legislating against the causes of lung cancer.
Asbestos became a major concern after it was linked as one of the causes of lung cancer because it was a commonly used substance. Let's look at how asbestos was used, its dangers, and the legislations put in place to prevent against its exposure.
Asbestos
A natural substance made from silicate. It is resistant to corrosion, heat, and electricity. When incorporated into fabrics and other substances, asbestos can add strength, fire resistance, and insulation properties to materials.
Asbestos was an incredibly useful substance that was used on a mass scale during the Industrial Revolution (1760-1840). It was used to make:
The versatility of asbestos meant that it was used widely in the UK's industries and had a massive benefit to the economy. Even as of 2021, it is estimated that 20% of workplaces and 75% of hospitals and schools have asbestos-containing materials in them.
Although asbestos was an incredibly useful substance, there are dangers associated with exposure to it.
Asbestos exposure became one of the key public health challenges with lung cancer. Let's look at the government acts that have aimed to reduce exposure to asbestos for factory workers and users of the products.
Even though asbestos was eventually banned for the severe health problems it caused, this process was slow because of the usefulness of the substance in industry.
Did you know? In 2018, the World Health Organisation (WHO) suggested that a global ban on asbestos would not have a negative effect on economies due to the reduction in asbestos-related healthcare.
Air pollution often contains particulate matter, such as soot, which is released from the fumes of factories and exhausts from vehicles. Along with the poisonous gases, these substances increase the risk of certain health conditions. In particular, polluted air is one of the causes of lung cancer.
Although polluted air is a major public health concern, the processes causing it were beneficial to the British economy.
Air pollution itself did not directly affect industries or the economy but became one of the significant public health challenges, with lung cancer being a result. Such problems with polluted air include:
The 1956 Clean Air Act was a major turning point for controlling harmful emissions. Air Quality Legislation throughout the 20th and 21st centuries has attempted to reduce the potential risks of lung cancer and other diseases.
Smoking is particularly difficult to legislate against because the habit is a personal choice, smoking is addictive, and there was pushback from the tobacco industry.
Although smoking is bad for your health, the tobacco industry was booming because of the habit. Below are some of the "benefits" of smoking.
Despite its relaxation effects, smoking causes considerable health problems.
Carcinogens
Substances that cause cancer.
As smoking is a personal choice rather than an effect of other industries (like asbestos and air pollution), legislation to reduce smoking in the UK came through public health anti-smoking initiatives and taxation and legislation against tobacco companies.
Throughout this process of legislation, the tobacco industry pushed back hard against the economic changes to their industry. Often tobacco companies would publish conflicting reports on the health benefits of smoking, which made turning public opinion difficult. The economic pushback from these companies contributed to the many public health challenges with lung cancer.
Lung cancer was first identified in the mid-19th century and was considered relatively rare at the time. But what has the trend in the rate of lung cancer been like since? Let's look at the history of lung cancer.
WHO (World Health Organisation) is a United Nations agency established in 1948 and is responsible for global public health. WHO cannot pass legislation but has had the ability to declare global health emergencies as of 2007.
Differences between male and female risk of lung cancer
The above graph shows how lung cancer has been decreasing in the last half-century. But what does it tell us about the differences between male and female risks of lung cancer in the UK?
The blue line shows that on average, fewer men have been dying of lung cancer as time has progressed, reducing from 16 million deaths in 1971 to around 7 million deaths in 2018, which can be attributed to a decrease in smoking habits among other causes.
However, the death rates for women have risen from around 2.5 to 5 million in the same time period. Scientists do not know why increasingly more women are dying from lung cancer. It appears that biologically women are more susceptible to developing lung cancer than men.
In the US, some 20% of female lung cancer patients have never smoked, which raises questions about the potential risks of lung cancer in relation to sex.
The decrease in smoking habits after the 1980s shows that the rate of lung cancer deaths has increased overall (the purple line), but the seemingly unexplained risk to women means the field requires more research.
The public health challenges with lung cancer have largely been helped by WHO's declaration that tobacco consumption is a global health emergency and the organisation's subsequent campaigning. So how did WHO help to reduce the rate of lung cancer?
WHO's comprehensive research, campaigns, and reports have demonstrated how health warnings, banning tobacco advertising and taxes are effective at reducing tobacco consumption. They have also campaigned for effective public health initiatives to help smokers to quit due to addiction issues.
Did you know? Since WHO's campaigns, the number of cases of lung cancer began to reduce after the 1980s. Between 1990 and 2018 the rate of lung cancer has decreased by around 9% in Britain.
The treatment of lung cancer has changed in recent years due to highly funded cancer research charities. This has helped to reduce the number of deaths from the disease. Let's look at some recent advances in the management of lung cancer.
Metastatic cancer
When one form of cancer spreads throughout the patient, affecting other areas of the body.
The fight against lung cancer has been a major public health challenge since cases of the disease began to rise significantly in the early 20th century. Due to advances in medical technology, the mortality rate has dropped, but the rate of cases is still a concern to public health. As lung cancer is considered a preventable disease, more work is needed to reduce the risk of the disease.
Lung cancer is a disease that affects the lungs when cells abnormally divide to form tumours.
Lung cancer is the third most common cancer in the UK. It is caused by many preventable issues such as exposure to harmful chemicals, air pollution and smoking. Lung cancer is estimated to have cost the UK economy around £2.4 billion in 2012.
The World Health Organisation has created many campaigns to reduce the consumption of tobacco throughout the global population. In 1970, WHO released a report called "the limitation of smoking" which caused cigarette use to drop by 5%. They create campaigns and conduct comprehensive research which urges governments to legislate harmful practices that can cause lung cancer.
Lung cancer was first identified in the mid-19th century by doctors. It is unclear who was first to make the discovery as lung cancer has been a human condition for centuries but was only very rare. After the Industrial Revolution, cases of lung cancer rose rapidly, raising major concerns for Public Health, and research into the causes of the condition.
