8 Shocking Signs of Lung Cancer That People Miss

Lung cancer affects millions of people around the world becoming one of the biggest risks to someones life. The early signs of lung cancer can be subtle but experts agree knowing how to spot them is critical.

Understanding Lung Cancer

Lung cancer is a disease in which malignant cells grow uncontrollably within the lungs, with the potential to spread rapidly to other parts of the body, including the lymph nodes. The disease usually originates in the bronchi cells, responsible for transporting oxygen to the lungs from the windpipe.

Who Faces Higher Risk of Diagnosis?

Lung cancer is considered quite common, affecting 1 in 16 individuals during their lifetime and numbers in America show one is diagnosed every two and a half minutes.¹ It takes the lives of nearly three times as many men as prostate cancer and three times as many women as breast cancer. Though slightly more prevalent in men, the difference is minimal. The risk of lung cancer increases with age, with those aged 65 and older being the most susceptible group. Additionally, African Americans face a heightened risk, with a 15% greater likelihood of developing the disease.¹²

Identifying Risk Factors

The primary risk factor for lung cancer is well-established and revolves around cigarette smoking, responsible for 80% of lung cancer deaths globally. Other contributing factors include exposure to harmful substances in work environments, such as radon gas, secondhand smoking (passive smoking), asbestos inhalation, air pollution, diesel and fuel exhaust, and toxic metals like arsenic, chromium, and cadmium. Family history also plays a role, elevating an individual’s risk of developing the disease. Regular screening is highly recommended for those with a genetic history of lung cancer.

Major Symptoms of Lung Cancer

Detecting lung cancer in its early stages can be challenging, as symptoms may not manifest until the disease has progressed. If you experience any of the following symptoms and have a history of smoking, it is strongly advised to consult your doctor immediately:

Chest pain
Shortness of breath
Unintentional weight loss
Persistent headache and dizziness
Coughing up blood
Fluid in the chest
Chronic cough
Bone pain

Diagnosing Lung Cancer

Lung cancer can be diagnosed through three primary methods. The most common approach involves a CT scan, which uses X-rays to visualize the internal structures of the body. Computed tomography is particularly effective in detecting nodules and small tumors in the early stages. Alternatively, MRI scanning provides similar results with less impact on the body. Following a positive CT scan result, biopsies are often performed, involving the insertion of a needle into the affected area to collect cell samples for lab analysis.³

Treatment Options

Treatment for lung cancer varies based on the stage of the disease. Surgery is typically considered a last resort if the cancer has spread to surrounding organs. For early-stage cases, chemotherapy and radiation therapy are the preferred treatment methods, effectively targeting cancer cells while preserving healthy ones. In some cases, patients may also have the opportunity to participate in clinical trials.

Who Is At Higher Risk of Lung Cancer?

Individuals with certain risk factors are at a higher risk of developing lung cancer. The primary risk factor for lung cancer is smoking cigarettes. It is responsible for about 80% of lung cancer cases worldwide. Other risk factors include:

Smoking: Current or former smokers have a significantly higher risk of lung cancer compared to non-smokers. The risk is directly related to the number of cigarettes smoked and the duration of smoking.
Secondhand Smoking (Passive Smoking): Non-smokers who are regularly exposed to secondhand smoke in their environment, such as living with a smoker or spending time in smoky environments, are also at an increased risk.⁴
Exposure to Harmful Substances: Occupational exposure to carcinogens like asbestos, radon gas, arsenic, chromium, and cadmium can elevate the risk of lung cancer.
Air Pollution: Prolonged exposure to air pollution, particularly in urban areas with high levels of pollutants, can contribute to an increased risk.
Family History: Individuals with a family history of lung cancer may have a higher likelihood of developing the disease, indicating a possible genetic predisposition.
Age: The risk of lung cancer increases with age, and it is more commonly diagnosed in older individuals, particularly those over 65 years old.

Reducing the Risk

The most effective way to reduce the risk of lung cancer is by quitting cigarette smoking, which remains the leading cause of the disease in both men and women worldwide. Adopting a well-balanced diet, rich in quality meats and vegetables, can strengthen the immune system and reduce inflammation, potentially helping to prevent cancer. Omega-3 fatty acids found in certain fish, such as salmon and sardines, are known to lower inflammation, offering potential protective benefits against cancer development.

Understanding the Stages of Lung Cancer

Lung cancer can be categorized into four stages, depending on the extent of its spread, time of diagnosis, and severity of the disease:

Stage 0: Cancer remains localized and asymptomatic, often leading to remission if detected early.
Stage 1: Cancer has spread within the lungs but remains contained, resulting in higher survival rates.
Stage 2: Cancer has spread to surrounding tissues and lymph nodes on a small scale, with good chances of recovery if detected early.
Stage 3: Cancer has extended to nearby tissues, organs, and lymph nodes on one or both sides of the chest.
Stage 4: Cancer has spread to other organs and systems in the body, such as the brain and bone marrow, making survival less probable.

Prioritize Lung Cancer Screening

If you experience any symptoms, have a history of smoking, or have a family history of lung cancer, it is essential to consult your doctor for screening. Early detection remains the most effective means of combating lung cancer and can significantly impact your chances of survival. For information on nearby professional screening centers or common symptoms, conduct a search to stay proactive about your health.
