Lung cancer is sometimes misdiagnosed as something less harmful, making lung cancer the 4th most claimed malpractice injury. For example a patient with a chronic cough may be diagnosed with bronchitis, without running the proper diagnostic test.
Some symptoms and signs of lung cancer:
- Persistent bouts of coughing.
- Persistant back pain, shoulder pain, or chest pain that worsens with deeper breathing.
- Shortness of breath.
- Hoarse voice.
- Coughing up blood or bloody mucus.
- Neck or facial swelling.
- Swallowing with difficulty.
- Weight loss or appetite loss.
- Feeling fatigue or weak.
- Periodic respiratory infections.
There are four types of lung cancer:
- Small lung cancer, accounts for about 20 to 25 percent of all lung cancer cases. It is found predominantly in people who are heavy smokers and most often develops in the bronchial submucosa. This form of lung cancer spreads rapidly and is more likely to metastasize than the other three forms of lung cancer.
- Squamous cell carcinoma, also called epidermoid cancer, makes up 25 to 30 percent of all lung cancer cases and is the most common form of lung cancer. It often begins in the bronchi and may remain in the lungs without spreading for a longer period of time than the other forms of lung cancer.
- Adenocarcinoma is a form of lung cancer with cancerous cells shaped as cubes or columns, which usually grow in patterns in the glands, along the tissue that lines the bronchi and along the outer edges of the lungs. It makes up 25 to 30 percent of all lung cancer cases.
- Large cell carcinoma is the rarest form of lung cancer, making up approximately 10 to 20 percent of cases. It is found most often in the bronchi and is made up of cancer cells that are not small lung cancer, squamous, or adenocarcinoma.
