Some of the most typical malignancies of the chest cavity include:

• Non-small cell lung cancer: Non-small cell lung tumor make up about 85% of lung cancer cases. These malignancies include adenocarcinoma, which starts in the lung’s mucus-secreting cells, squamous cell carcinoma, which begins in the cells that line the lungs, and big cell carcinoma (which can begin in any part of the lung).
• Small-Cell lung cancer: The percentage of small-cell lung malignancies is between 10%-15%. Since it can develop anywhere in the lung and usually spreads quickly, this type of cancer is both easier to cure and more likely to come back over time.
• Mesothelioma: In the pleura, peritoneum or other tissues that line the abdominal cavity, mesotheliomas first appear.
• Thymic Malignancy (sometimes known as a thymoma):The thymus is a tiny organ in the chest that controls the lymphatic system and is located directly below the breastbone (which makes white blood cells). Thymomas or thymic malignancies are terms used to describe cancers that develop in the thymus.
• Other malignancies:Thoracic cancer can occasionally develop from cancers that started elsewhere in the body and spread to the lungs or other organs in the chest cavity. These cancers include breast cancer, pancreatic cancer and a few others.

What are the signs and symptoms of thoracic cancer?

Signs and symptoms of throat cancer are listed below as:

• Severe Cough
• Chest pain
• Night sweats
• Fever
• Unexplained weight loss
• Bloody or rust colored mucus
• Shortness of breath
• Weakness
• Shoulder pain

• Noticing one or more of these symptoms does not necessarily indicate that you have cancer because they are equally frequent in other illnesses. Some patients receive a diagnosis with no warning symptoms at all. The only way to be certain is to go to a doctor.

Causes of Lung Cancer

•   Cellular DNA has been repeatedly damaged, which leads to cancer. Genes may mutate if they sustain harm. The resulting aberrant cell development might go throughout the body as a result of these abnormalities. When this unnatural growth takes place in the chest cavity, thoracic malignancies are the result.
  
    The exact cause of any diseases including thoracic cancer, is unknown to medical professionals. Age, hormones and genetics (certain cancer tend to run in families) are biological elements that can cause cell damage and raise the risk of developing cancer.
  
    Environmental risk factors include exposure to radiation from the sun or cancer-causing chemicals like asbestos and radioactive materials.
  
    Lifestyle changes, particularly nutrition, body weight and smoking are particularly important for thoracic malignancies. In actuality, smoking significantly raises the risk of esophageal cancer and is associated with 90% of instances of lung cancer.

Risk Factors

• Smoking is the major risk factor for thoracic cancer. Nearly all lung cancers are caused by smoking wither currently or in the past. Particularly small cell lung cancer is extremely uncommon in non-smokers.
  
  Your risk increases with the length of time and number of cigarettes you smoke. Your risk increases with the length of time and number of cigarettes you smoke. Your risk also rises when you are around smokers. Each year, thousands of cases of thoracic cancer are brought on by this “second-hand” smoke.

Other typical risk elements include:

• Exposure to radiation and radioactive materials:Radiation and radioactive material exposure, prior cancer therapy, radon exposure and excessive UV radiation are all risk factors for thoracic cancer.
• Workplace exposures:Exposure to asbestos, which is frequently found in shipyards, factories and mines, for example increases the risk of lung cancer
• Exposure to additional carcinogens:In addition to silica, coal, air pollution and diesel fumes, other carcinogens include heavy metals including arsenic, beryllium and cadmium.
• Family lung cancer history.

Diagnosis

• Lung cancer diagnosis may involve several steps. During your initial visit to a healthcare professional, they will listen to your symptoms, inquire about your medical history and conduct a physical examination. Your doctor, ay begin by ordering blood tests and chest X-ray because the symptoms of lung cancer are similar to those of many other, less serious conditions.
