Lung cancer is one of the most common and deadly forms of cancer worldwide. It often develops silently, with symptoms appearing only in the advanced stages. However, early diagnosis can significantly improve outcomes and survival rates. Recognizing the warning signs and knowing when to consult a lung oncologist is crucial. In this blog, we’ll explore the early symptoms of lung cancer, diagnostic approaches, and why Dr. Sumant Gupta is regarded as the best cancer doctor in Faridabad.


Understanding Lung Cancer

Lung cancer begins when abnormal cells grow uncontrollably in one or both lungs. These cells can form tumors and interfere with the lung’s ability to provide oxygen to the body. There are two main types:

  • Non-Small Cell Lung Cancer (NSCLC): The most common type, accounting for about 85% of cases.

  • Small Cell Lung Cancer (SCLC): A more aggressive form that spreads quickly.

Smoking is the primary cause of lung cancer, but non-smokers can also develop the disease due to factors like air pollution, occupational exposure, secondhand smoke, and genetic predisposition.


When Should You See a Lung Oncologist?

Early detection saves lives. If you experience persistent or unexplained symptoms that may indicate lung cancer, consult a lung oncologist without delay. Below are the key warning signs.


Early Warning Signs of Lung Cancer

1. Chronic Cough That Doesn’t Go Away

A lingering cough lasting more than 2–3 weeks should not be ignored, especially if it worsens or changes in sound.

2. Coughing Up Blood (Hemoptysis)

Even a small amount of blood in sputum is a red flag and must be evaluated immediately.

3. Shortness of Breath

Breathlessness during routine activities, or while at rest, may signal lung abnormalities.

4. Chest Pain

Persistent pain in the chest, especially when coughing, breathing, or laughing, could be linked to lung tumors.

5. Hoarseness

A tumor pressing on the laryngeal nerve may cause voice changes.

6. Unexplained Weight Loss

Sudden and unintentional weight loss often accompanies cancers, including lung cancer.

7. Fatigue

Ongoing exhaustion not linked to physical activity may be a sign of a serious underlying issue.

8. Frequent Lung Infections

Recurring bronchitis or pneumonia might indicate an obstruction caused by a tumor.


Who is at Risk?

Knowing the risk factors helps determine whether you should undergo regular screening or consult a specialist.

  • Smokers and Former Smokers

  • People over 50 years of age

  • Exposure to asbestos, radon gas, or heavy metals

  • Family history of lung cancer

  • Prolonged exposure to air pollution


Diagnosis: What to Expect When You Visit a Lung Oncologist

If your physician suspects lung cancer, you will be referred to a lung oncologist for further evaluation. The process typically includes:

1. Imaging Tests

  • Chest X-ray

  • CT Scan or PET Scan to detect the size and location of tumors.

2. Biopsy

A tissue sample may be taken using techniques like bronchoscopy, needle biopsy, or surgical biopsy to confirm the presence and type of cancer.

3. Molecular Testing

Advanced testing identifies genetic mutations or biomarkers (e.g., EGFR, ALK), which can guide targeted therapy.

4. Pulmonary Function Tests

To assess lung capacity before planning surgery or other treatments.


Why Early Diagnosis Matters

Lung cancer diagnosed in its early stages (Stage I or II) has a far better prognosis. Many early-stage patients may benefit from curative treatments such as:

  • Surgical Removal of Tumors

  • Targeted Therapy

  • Radiation Therapy

  • Immunotherapy

  • Chemotherapy (in specific cases)

Delaying diagnosis often results in cancer spreading to other organs, making it more difficult to treat effectively.

When to Get Screened for Lung Cancer?

For high-risk individuals, annual screening using a low-dose CT scan (LDCT) is recommended. According to medical guidelines:

  • Adults aged 50 to 80 with a history of heavy smoking

  • Those who currently smoke or have quit within the past 15 years

Early screening can detect tumors before symptoms appear, increasing treatment success.

Yes, about 10–20% of lung cancer cases occur in non-smokers due to pollution, genetic mutations, or secondhand smoke.

Q2. Is lung cancer curable?

Yes, if detected early. Stage I or localized tumors may be cured through surgery and other treatments.

Q3. What is the survival rate of lung cancer?

The 5-year survival rate is over 60% for early-stage lung cancer but much lower if diagnosed late.

Q4. How long does it take to get diagnosed?

The complete diagnostic process may take 1–2 weeks, including scans, biopsy, and pathology reports.

Q5. What is the role of a lung oncologist?

A lung oncologist specializes in diagnosing and treating lung cancers, recommending appropriate therapies, and managing side effects.
