bronchus carcinoma

Bronchus carcinoma, also known as lung cancer or bronchogenic carcinoma, refers to tumors originating in the lung parenchyma or within the bronchi. It is a type of cancer that starts when abnormal cells grow in an uncontrolled way in the lungs.

Types of Bronchus Carcinoma

There are several types of bronchus carcinomas, including:

• Squamous cell carcinoma: This type of cancer starts in squamous cells, which are flat cells that line the inside of the airways in the lungs. It is often linked to a history of smoking and tends to be found in the central part of the lungs, near a main airway (bronchus) [1].
• Small cell lung cancer (SCLC): This fast-growing cancer grows in lung tissue and has two subtypes: small cell carcinoma and combined small cell carcinoma (which has a mix of small and non-small cells.) SCLC accounts for about 15% of lung cancer diagnoses [11].
• Non-small cell lung cancer (NSCLC): NSCLC accounts for most bronchogenic carcinomas (around 80% to 85%) [11].

Symptoms

The symptoms of bronchus carcinoma can include:

• Chest pain
• Cough that does not go away
• Shortness of breath
• Wheezing
• Hoarseness
• Loss of appetite
• Weight loss

These symptoms may vary depending on the type and stage of the cancer [7].

Diagnosis

To diagnose bronchus carcinoma, doctors may order imaging tests such as X-rays or CT scans to identify and evaluate possible tumors. They may also recommend a biopsy to confirm the diagnosis [12]. An experienced lung pathologist will determine the specific type of lung cancer.

Prevalence

Lung cancer is a leading type of cancer, equal in prevalence to breast cancer [14]. It is the leading cause of cancer mortality worldwide; accounting for ~20% of all cancer deaths [14].

Common Signs and Symptoms of Bronchus Carcinoma

Bronchus carcinoma, also known as lung cancer, can manifest in various ways, making it challenging to diagnose early on. Here are some common signs and symptoms associated with this disease:

• Persistent or worsening cough: A cough that doesn't go away after 3 weeks or gets worse over time is a common symptom of bronchus carcinoma [1][2].
• Chest pain: Chest pain, especially when deep breathing, can be an indication of lung cancer [3][4].
• Shortness of breath: Feeling short of breath even when sitting still or engaging in light physical activity can be a sign of advanced lung cancer [5][6].
• Weight loss and loss of appetite: Unexplained weight loss and decreased appetite are common symptoms of many cancers, including bronchus carcinoma [7][8].
• Coughing up blood: Coughing up blood or rust-colored mucus is a serious symptom that requires immediate medical attention [9][10].

Other Possible Symptoms

In addition to the above-mentioned symptoms, some people may experience:

• Arm or shoulder pain
• Headaches
• Bone pain or fractures
• Blood clots

It's essential to note that these symptoms can be subtle and easily mistaken for minor health issues. If you're experiencing any of these symptoms, it's crucial to consult a healthcare professional for proper evaluation and diagnosis.
