It can be any type or subtype of lung cancer that began in the bronchi and bronchioles, the passageways to the lungs.

Symptoms of Bronchogenic Carcinoma

Early symptoms of bronchogenic carcinoma can be so mild that they don’t ring any alarm bells. Sometimes, symptoms are not noticeable until the cancer has spread.

Most common Symptoms of lung cancer:

Persistent or worsening cough
Wheezing
Coughing up blood and mucus
Chest pain that gets worse when you take a deep breath, laugh, or cough
Shortness of breath
Hoarseness
Weakness, fatigue
Frequent or persistent attacks of bronchitis or pneumonia

Symptoms that cancer has spread may include:

Hip or back pain
Headache, dizziness, or seizures
Numbness in an arm or leg
Yellowing of the eyes and skin (jaundice)
Enlarged lymph nodes
Unexplained weight loss

Causes of Bronchogenic Carcinoma

It begins when cells in the lung start to mutate. Instead of dying off as they should, the abnormal cells continue to reproduce and form tumors.

The most common cause is

1. Smoking.

2. Exposure to radioactive gas that can come up through soil and into buildings.

3. Breathing in hazardous chemicals such as asbestos, arsenic, cadmium, chromium, nickel, uranium, and some petroleum products

4. Exposure to exhaust smoke and other particles in the air

5. Genetics; a family history of lung cancer may place you at higher risk

6. Previous radiation to the lungs

7. Exposure to high levels of arsenic in drinking wate

Diagnosis of Bronchogenic Carcinoma

Imaging tests.
Sputum cytology.
Biopsy.

If cancer is detected, the pathologist will also be able to identify which type of lung cancer it is. Then the cancer can be staged. This may require additional testing such as:

Biopsy of other organs with suspicious areas
Imaging tests, such as CT, MRI, PET, or bone scans on other parts of the body
