In lung cancer, time is the variable that matters most. The interval between a suspicious shadow and a confirmed diagnosis with an accurate stage often determines which treatments remain possible. Lung cancer diagnosis in Rewari at Vaayu Care is built to shorten that interval: bronchoscopy, endobronchial ultrasound and thoracoscopy are performed in house by Dr. Ajit Yadav rather than referred onward.
Warning signs
Lung cancer frequently causes no symptoms until it is well established, which is why an incidental finding on a scan should never be ignored. Warning signs include:
- A cough lasting more than three weeks, or a change in a long-standing cough
- Coughing up blood, even once, in any quantity
- Breathlessness or wheeze that is new and persistent
- Chest, shoulder or back pain that does not settle
- Unexplained weight loss and loss of appetite
- Persistent fatigue
- Hoarseness of the voice
- Repeated chest infections in the same area of lung
- Swelling of the face or neck, or new prominent veins on the chest
- Finger clubbing
Any single episode of coughing up blood in an adult over forty who smokes warrants a chest X-ray and, in most cases, a CT scan.
Risk factors
Smoking remains the dominant cause, and risk rises with both the amount and the duration — but a substantial and growing proportion of patients have never smoked. Other factors include second-hand smoke; biomass and cooking smoke; occupational exposure to asbestos, silica, arsenic, chromium and diesel exhaust; radon; long-term outdoor air pollution; previous tuberculosis or COPD, both of which independently raise risk; previous radiotherapy to the chest; and a family history of lung cancer.
How lung cancer is diagnosed and staged
Two questions must be answered: what is it, and how far has it spread. Both are needed before treatment can be planned.
- CT chest with contrast defines the lesion and looks at lymph nodes, the pleura, liver and adrenal glands.
- PET-CT identifies metabolically active disease and often detects spread not visible on CT.
- Tissue diagnosis is essential — no cancer treatment begins without it. The route depends on where the lesion sits:
- Flexible bronchoscopy for lesions in or near the airways, with washings, brushings and biopsy.
- Endobronchial ultrasound (EBUS) to sample mediastinal lymph nodes and central masses with a needle under real-time ultrasound guidance.
- CT-guided biopsy for peripheral lesions near the chest wall.
- Medical thoracoscopy where fluid has collected around the lung, allowing diagnosis and drainage in one sitting.
- Molecular and immunohistochemical testing on the sample identifies EGFR, ALK, ROS1 and other mutations, and PD-L1 expression. These results determine whether targeted therapy or immunotherapy is possible and are now as important as the cell type itself.
- MRI brain and bone imaging where clinically indicated.
Why EBUS matters for staging. Whether mediastinal lymph nodes contain cancer decides whether surgery is appropriate or whether chemoradiotherapy or systemic treatment is the better route. EBUS samples these nodes with a needle passed through the airway wall, as a day-case procedure under sedation. Before EBUS this often required mediastinoscopy — a surgical procedure under general anaesthetic.
Treatment
Treatment is decided by cell type, stage, molecular profile and how fit the patient is, and is planned jointly with oncology and thoracic surgery colleagues.
Surgery offers the best chance of cure in early-stage disease confined to the lung, provided lung function is adequate — which is assessed formally before any operation.
Radiotherapy, including stereotactic radiotherapy for small tumours, is used curatively where surgery is not suitable, and for symptom control in advanced disease.
Systemic therapy — chemotherapy, targeted therapy against a specific mutation, or immunotherapy — is chosen on the molecular profile. Targeted and immune treatments have changed outcomes substantially for suitable patients.
Interventional pulmonology manages the complications of advanced disease and can transform symptoms: debulking tumour blocking a major airway, airway stenting to relieve breathlessness from obstruction, controlling bleeding, and draining recurrent pleural fluid with talc pleurodesis or an indwelling catheter.
Supportive care — pain control, nutrition, breathlessness management and psychological support — runs alongside treatment from the beginning, not only at the end.
The role of the chest physician
The pulmonologist is usually the first specialist involved and stays involved throughout: securing the diagnosis quickly, staging accurately, assessing whether lung function permits surgery, managing airway complications, and treating the COPD or fibrosis that so often coexists.
When to seek assessment in Rewari
Book a consultation urgently if you have coughed up blood, if a scan has shown a nodule, mass or shadow needing explanation, if a chest infection has not cleared after treatment, if you have a persistent cough with weight loss, or if you have been told you need a biopsy or staging and want it done without delay.
Bring all previous CT films and reports. Book an appointment at Vaayu Care, Rewari.
Frequently asked questions
Does a lung nodule on a scan mean cancer?
Usually not. Most small nodules are benign — old infection, scarring or healed tuberculosis are common explanations in India. What matters is size, shape, edge characteristics, growth over time and your risk profile. Many nodules are managed with interval CT scans to confirm stability; only those with concerning features need a biopsy.
I have never smoked. Can I still get lung cancer?
Yes. A significant and rising proportion of patients have never smoked. Second-hand smoke, biomass and cooking smoke, occupational exposure to asbestos and silica, radon, air pollution and previous tuberculosis or COPD all contribute. Never having smoked should not delay the investigation of persistent symptoms.
Why do I need EBUS if the CT already shows the cancer?
A CT scan shows where abnormalities are but cannot confirm what they are. Enlarged lymph nodes may be reactive rather than cancerous, and normal-sized nodes can still contain cancer. EBUS samples them directly, which determines the stage — and stage determines whether surgery is possible. Treating on imaging alone risks both over- and under-treatment.
How quickly can a diagnosis be reached?
Where bronchoscopy, EBUS and thoracoscopy are available in the same place, tissue diagnosis is often obtained within days of the first consultation, with molecular results following in one to two weeks. The delay in most patients' journeys comes from referral between centres, which is exactly what an in-house service avoids.
Is a biopsy risky, and can it spread the cancer?
Biopsy does not spread cancer — this is a persistent myth that causes harmful delay. Bronchoscopic and EBUS biopsies are performed under sedation as day cases and are generally very safe. The main risks are minor bleeding and, with needle biopsy through the chest wall, a small chance of lung collapse, which is explained and monitored for.
What if fluid keeps collecting around my lung?
Recurrent pleural fluid is common in advanced disease and causes considerable breathlessness. Medical thoracoscopy allows the fluid to be drained, the pleura inspected and biopsied, and talc pleurodesis performed to stop it reaccumulating — often in a single procedure. An indwelling drainage catheter is an alternative for some patients.
