Lung Cancer Symptoms and Signs
What are the lung cancer signs and lung cancer symptoms ? The symptoms of lung cancer vary widely depending on the location and extent of the tumor. Warning signs of lung cancer are not always present or readily identifiable. A person with lung cancer May of the following types of symptoms:
- No symptoms
It’s up to 25% of people who develop lung cancer, the cancer is discovered at a routine chest X-ray or CT scan as a solitary small mass sometimes called the currency of an injury, given as two dimensions X – ray or CT scan, the tumor-round as a coin. These patients often report only small masses have no symptoms when the cancer is discovered.
- The symptoms associated with cancer
Tumor growth and invasion of lung tissue and surrounding tissues can cause breathing, causing symptoms such as cough, dyspnea, wheezing, chest pain and coughing up blood (hemoptysis). If the cancer has invaded nerves, for example, can cause pain in the shoulder on the outside of the arm (called Pancoast’s Syndrome) or paralysis of the vocal cords leading to hoarseness. Invasion of the esophagus may cause difficulty in swallowing (dysphagia). If an airway is obstructed large, the collapse of part of the lung may occur and cause infections (abscesses, pneumonia) in the blocked area.
- Symptoms related to metastasis
Lung cancer that has spread to the bones may produce excruciating pain in areas of bone involvement. Cancer that has spread to the brain can cause a range of neurological symptoms may include blurred vision, headaches, seizures or stroke symptoms as weakness or numbness in parts of the body.
- Paraneoplastic symptoms
Lung cancers are often accompanied by symptoms resulting from the production of the hormone-like substances by tumor cells. These paraneoplastic syndromes occur most often with SCLC in may, but should be viewed with any type of tumor. A common paraneoplastic syndrome associated with SCLC is the production of a hormone called adrenocorticotropic hormone (ACTH) by the cancer cells, resulting in the hypersecretion of cortisol, a hormone of the adrenal glands (Cushing’s syndrome). Most common paraneoplastic syndrome with NSCLC is the production of a substance similar to parathyroid hormone, which causes high calcium levels in the blood.
- No specific symptoms
No specific symptoms seen with many cancers, including lung cancer, including weight loss, weakness and fatigue. Psychological symptoms such as depression and mood swings are also common.
