Lung Nodule
Evaluation in Hyderabad
Your CT report says "nodule seen" or "shadow in right lung."You've been told to see a specialist. You don't know what this means or how urgent it is.
Most lung nodules are benign. But the ones that aren't — caught early — are curable. The difference between the two is a structured evaluation, not a waiting game.

Why Patients Come to Dr. Kunal for Nodule Evaluation
Linear + Radial EBUS — tissue diagnosis without surgery or chest wall puncture
One of very few interventional pulmonologists in Hyderabad with dedicated radial EBUS experience
Fleischner Society criteria applied to every nodule — no over-investigation, no under-investigation
Same-week appointments for CT reports with suspicious features
Cryobiopsy available — larger, better-preserved tissue samples than forceps biopsy
What Is a Pulmonary Nodule?
A pulmonary nodule is a small, round or oval-shaped growth in the lung — typically less than 3 cm in diameter. It shows up on a CT scan as a white, coin-like shadow. Anything larger than 3 cm is called a lung mass and treated differently.
Benign causes (most common)
- Tuberculoma — healed TB granuloma
- Fungal granuloma (histoplasma, aspergillus)
- Intrapulmonary lymph node
- Hamartoma (benign lung tumour)
- Scarring from old infection or inflammation
Features that raise concern
- Size above 8mm
- Spiculated (jagged) margins
- Upper lobe location
- Solid density (not ground-glass)
- New or growing on comparison CT
- Smoking history + age above 50
Malignant causes
- Primary lung cancer (adenocarcinoma, squamous cell)
- Carcinoid tumour
- Metastasis from breast, colon, kidney, thyroid
- Lymphoma involving the lung
- Rare primary lung malignancies
How We Decide What to Do — Fleischner Society Criteria
Not every nodule needs a biopsy. Not every nodule can wait. The Fleischner Society — the international authority on nodule management — provides structured criteria that Dr. Kunal applies to every case.
Under 6 mm · Solid · Low risk patient
No routine follow-up CT needed
Under 6 mm · Solid · High risk patient (smoker, family history)
Optional CT at 12 months
6–8 mm · Solid · Low risk patient
CT at 6–12 months, then at 18–24 months if stable
6–8 mm · Solid · High risk patient
CT at 6–12 months. If unchanged, repeat at 18–24 months
Above 8 mm · Solid · Any patient
CT at 3 months, or PET scan, or tissue sampling — based on CT appearance
Ground-glass or part-solid nodule (any size)
CT at 3–6 months to confirm persistence, then annual for 5 years
Growing or new nodule on comparison CT
Urgent evaluation — growth is the highest-risk feature
The Evaluation Process at Respire
CT Review and Risk Stratification
Dr. Kunal reviews your CT images — not just the report. Nodule size, density (solid vs ground-glass vs part-solid), shape (smooth vs spiculated), location (upper vs lower lobe, central vs peripheral), and any associated features (pleural tags, satellite nodules, lymphadenopathy) are assessed against your clinical history. Risk is stratified using Fleischner Society and BTS criteria.
Comparison with Old Imaging
Growth rate is one of the most powerful discriminators between benign and malignant nodules. A nodule stable for 2+ years is almost certainly benign. A nodule that doubled in volume in 3 months needs tissue urgently. If you have older chest X-rays or CT scans from any facility, bring them — they change the management plan more than almost any other factor.
PET Scan (for Selected Nodules)
A PET-CT scan measures metabolic activity. Malignant nodules are metabolically active and light up on PET. Used selectively for nodules above 8mm where CT appearance is ambiguous. Not required for every patient — Dr. Kunal decides case by case to avoid unnecessary cost and radiation.
Tissue Sampling if Needed (EBUS, Cryobiopsy, or CT-Guided)
When tissue is needed: Linear EBUS for central masses and enlarged lymph nodes. Radial EBUS for peripheral nodules in the outer lung — a bronchoscope with a radial ultrasound probe navigates to the nodule without chest wall puncture. Cryobiopsy — freeze-and-extract technique — delivers a larger, better-preserved sample. CT-guided biopsy coordinated with interventional radiology for nodules not reachable bronchoscopically.
Oncology Coordination if Cancer Confirmed
If the biopsy confirms malignancy, Dr. Kunal coordinates with thoracic surgeons, medical oncologists, and radiation oncologists at partner hospitals. Molecular testing (EGFR, ALK, ROS1, KRAS, PD-L1) is sent at the time of biopsy to avoid repeat sampling. The goal is to move from diagnosis to treatment plan within 2–3 weeks.
How Hyderabad Patients Arrive at This Decision
Three common presentations — each needs a different response.
Presentation
A 58-year-old man from Banjara Hills went for a routine health checkup. CT chest — done because his employer insisted — showed a 9mm right upper lobe nodule with spiculated margins. He had smoked 20 cigarettes a day for 25 years before quitting 5 years ago.
What Was Done
CT features (spiculated, upper lobe, >8mm) combined with the ex-smoking history placed him in high-risk category. A PET-CT was done to assess metabolic activity — the nodule lit up. Radial EBUS was performed; cryobiopsy confirmed adenocarcinoma, Stage 1A. He was referred to thoracic surgery. Surgical resection was curative.
Outcome
5-year survival for Stage 1A lung cancer: 80–90%. This is the best outcome possible — caught before symptoms, before spread.
Presentation
A 45-year-old woman from Secunderabad with a history of pulmonary TB 18 years ago was referred after a chest X-ray showed a 12mm nodule in the right upper lobe. She had never smoked and had no respiratory symptoms.
What Was Done
CT showed a calcified nodule with central calcification — classic tuberculoma pattern. Stability was confirmed by comparing with an old CT done 4 years previously at a government hospital — zero growth. No biopsy was needed. She was reassured with a single follow-up CT in 12 months to confirm continued stability.
Outcome
Unnecessary bronchoscopy avoided. Correct reassurance given. One follow-up CT was all that was required.
Presentation
A 52-year-old construction worker from LB Nagar was referred with a persistent 6-week cough. Chest X-ray reported as normal. HRCT showed two 7mm ground-glass nodules in the left lower lobe, not visible on plain X-ray.
What Was Done
Ground-glass nodules at this size follow a longer surveillance schedule. A baseline CT was done for precise measurement. CT at 6 months showed no growth. Annual CT surveillance was scheduled for 5 years per BTS guidelines. Occupational exposure history (silica, cement dust) was documented for the record.
Outcome
No biopsy at this stage. Lung cancer excluded at current probability. Surveillance programme initiated — if growth occurs, tissue can be obtained promptly.

Frequently Asked Questions
My CT scan shows a lung nodule — does this mean I have cancer?
No. The overwhelming majority of pulmonary nodules are benign — granulomas from old TB or fungal infection, intrapulmonary lymph nodes, or scarring. Studies show that 96–98% of nodules found on routine CT scans in low-risk individuals are not cancer. Certain features raise concern and need evaluation — but a nodule on a CT report is not a cancer diagnosis.
What does a 6mm, 8mm, or 10mm lung nodule mean?
Size is the most important initial factor. Nodules under 6mm in low-risk patients typically need no follow-up CT. Nodules 6–8mm need a repeat CT in 6–12 months to check for growth. Nodules above 8mm need CT in 3 months, PET scan, or biopsy depending on appearance. Your smoking history, age, and nodule characteristics all modify this.
I had TB 15 years ago. Could this nodule be from old TB and not cancer?
Very likely yes. Tuberculoma — a healed TB granuloma — is one of the most common causes of pulmonary nodules in India. On CT, TB granulomas typically appear calcified and stable. Patients with a TB history also have a slightly elevated lung cancer risk due to post-TB inflammation. Comparison with old CT scans is the most useful first step.
How is a lung nodule biopsied without surgery?
Linear EBUS samples nodules adjacent to the central airways or enlarged lymph nodes. Radial EBUS reaches peripheral nodules in the outer lung via a bronchoscope with an ultrasound probe. Cryobiopsy gives a larger, better-preserved tissue sample. CT-guided biopsy is used when nodules are peripheral and not reachable bronchoscopically. Dr. Kunal chooses the method based on nodule location, size, and patient fitness.
Can I wait and watch, or do I need to act immediately?
It depends entirely on the nodule. Nodules under 6mm in a non-smoker — watchful waiting is appropriate. Nodules above 8mm, rapidly growing nodules, or nodules with suspicious features need urgent evaluation — ideally within 2–4 weeks. A single specialist consultation to review your CT images will tell you exactly which category you fall into.
Is EBUS available in Hyderabad for lung nodule biopsy?
Yes. Dr. Kunal Waghray performs both linear and radial EBUS at Respire Airway Clinics. Radial EBUS — the method used to reach peripheral lung nodules — is available at very few centres in Hyderabad. Dr. Kunal has performed over 100 radial EBUS procedures.
