Introduction to Lung Cancer

With an incidence of lung cancer, a disease with an acute edge, no one will generally see a warning bell for it. All you need to do is know it very well as a silent killer—how to see it from the early signs so that chances can be increased to treat success.
Lung cancer occurs from the rapidly replicating abnormal cells in the lungs whose offshoot is the formation of tumors. These tumors could probably spread elsewhere in the body; hence, an early indication is crucial. Smokers are at the highest risk; however, other factors, like inhaling secondhand smoke, air pollution, and some occupational hazards, also contribute to the disease.
Lung cancer is generally silent, and for this reason, diagnosis usually comes very late. Proper checkups and timely health screenings, including CT scans, are instrumental in the early detection of lung cancer. Early detection has made important improvements in life expectancy and lung cancer treatment outcomes. Awareness of lung cancer symptoms and all those aspects related to delays in detection will support individuals in taking proactive steps toward their lung health.
Until now in 2024, lung cancer occupies a prominent place as a health problem in Qatar, being one of the most common cancers. Although, there are often no clear statistics regarding its dominance and severity.
Through this blog, we will be guiding you to understand the signs and symptoms of lung cancer, how to find them at the earliest stage, and how to protect your health and safety as well as the health and safety of your family.

What is Lung Cancer?

Lung cancer is a tumor in the lungs formed by hyperplasia of lung cells. It can invade adjacent and distant tissues, making it more fatal. Lung cancer metastasizes and spreads by infiltrating surrounding tissues and also through blood and lymphatic vessels to invade other organs.
  • Genetic predisposition: Variation of genes or genetic conditions can manifest lung cancer even among nonsmokers. 
  • Environmental exposures to all hazardous materials in the workplace as asbestos, radon, air pollutants, and man-made chemicals can impose a risk. 
  • Secondhand: Secondhand smoke is burning your lungs and making you likely to get lung cancer. Even if it is the main cause, the study finds that the cases among those who never smoked keep on increasing besides being the No. 1 cause. Therefore, it is essential to look for risk factors and preventive avenues.
The rising trend in lung cancer prevalence among non-smokers in Qatar makes it sensible to popularize awareness of these risk factors, promote regular screenings, and preventive strategies such as minimizing exposure to harmful agents and smoking prohibition programs.
In addition, public health interventions aimed at reducing air pollution and shielding people from secondhand smoke will also contribute significantly to alleviating the burden of lung cancer within the country.

Types of Lung Cancer

Lung cancer is one major serious disease of two main types:
  • Non-small Cell Lung Cancer-  
It is the most common form, comprising close to 85 percent of all lung cancers. Compared to SCLC, NSCLC has relatively slow growth and spread.
  • Small Cell Lung Cancer- 
Although a less common form of lung cancer, SCLC is more aggressive. This form grows fast and spreads to infect other parts of the body. It is usually diagnosed in the bodies of long-term smokers.
The severity of lung cancer depends upon the lung cancer stages, varying from stage 1 to stage 4.

Symptoms of Lung Cancer

A dangerous health condition called lung cancer tends to manifest symptoms that seem to be normal illnesses to this extent and other possibilities. These also depend on the lung cancer stages. A few of the lung cancer symptoms include:
What are the steps you can take to alleviate your risk of contracting STDs?
    •  Persistent Cough or Coughing Up Blood 
    A cough that occurs for the same time period every day on a daily basis and no improvement is seen is the warning sign. Coughing blood out, which is also referred to as hemoptysis, is another disturbing symptom.
    •  Chest Pain and Difficulty Breathing 
    Chest pain is often, especially in the ones where the pain is doubled when breathing deeply or coughing, a distinct indicator of lung cancer. Breathing cannot be done comfortably, a condition referred to as dyspnea, when a person is experiencing that situation even in the cases when they are making no hard movements.
    •  Fatigue and Unexplained Weight Loss  
    The feeling of tiredness unnaturally and observing unexpected weight loss, even in the absence of changes in diet or exercise routine, might be due to the existence of some health problems, including lung cancer.
    •  Hoarseness or Changes in Voice   
    A constant change in voice pitch can be an indication of an issue in the vocal cords or nearby areas and might result from lung cancer.
Furthermore, recognizing early lung infection symptoms, such as persistent coughing, shortness of breath, or chest discomfort, is crucial for timely intervention.
By fostering a proactive approach to respiratory health, individuals can not only address potential infections early such as symptoms of lung infections like persistent cough, chest pain, shortness of breath, and fever, but also improve the likelihood of detecting lung cancer at a treatable stage, ultimately enhancing overall health outcomes in Qatar.

Early Detection of Lung Cancer

The early detection of lung cancer is vital for improved survival rates. Screening tools such as CT and PET scans play an essential role. Recognizing lung infection symptoms, such as chest pain, shortness of breath, and persistent cough, can also aid early diagnosis.

Lung Cancer Screens

Regular screening is highly recommended for high-risk populations, such as individuals with heavy smoking habits or exposure to environmental pollutants. Lung cancer screening also depends on the causes of lung cancer.
In Qatar, advanced diagnostic tools and screening tests are available to support the early detection of lung cancer, along with lung infections symptoms, especially considering the region’s environmental factors, such as dust and air quality:
  • CT Scans: CT scans provide detailed images of the lungs, helping to detect abnormalities such as tumors.
  • PET Scans: PET scans assess the metabolic activity of cells, which can help identify cancerous tissues and early-stage tumors.

Recommendations for At-Risk Individuals

Family history of lung cancer, exposure to secondhand smoke, or exposure at work demands proactive assessment to reduce risks of contracting the disease by following all the steps below:
  • Quit Smoking: It is the primary cause of lung cancer. The best thing is to stop smoking completely. 
  • Routine Health Access: Conducting routine health access consults is very important in health access especially when one’s family has a background of lung cancer or when the person in consideration has any history of smoking. 
  • No Exposure to Secondhand Smoke: Then exposure to secondhand smoke will also escalate the risk of lung cancer. 
  • Health Check-Ups: Routine health check-ups take a very crucial role in maintaining health especially when the family has surpassed any heredity of lung cancer or when the person has any history of smoking.
  • Routine health check-ups at home and access to lab tests at home enhance the chances of identifying issues early. In Qatar, services like these are making proactive health management more accessible with First Response Healthcare Center, connect with us at [+971 5050 3388] 

Lung Cancer Treatment Options

Some of the many available treatments for lung cancer vary with the type of the disease and its stage, but their main goals will include cure or control of cancer in the lungs and symptomatic relief.
  • Surgery: Whenever it is possible, the surgical removal of cancerous tissues into the lung offers hope against early lung cancer.
  • Chemotherapy: The treatment course uses agents that by coming together destroy cancer cells and the application of this chemotherapy can be done on all parts of the body.
  • Radiotherapy: The cells with the highest energies kill the tumor cells and reduce tumor size.
  • Immunotherapy: it is a procedure that employs the immune system to destroy those malignant cells.
