What is lung cancer?
Malignant tumors on the other side increase aggressively and other tissues of the body, so that the infiltration of tumor cells in the bloodstream or the lymphatic system, and then in other places in the body to penetrate. This process is called metastasis. Tumor growth in these distant places are called metastases. Because it tends to grow or metastasize very early after they form, it is to treat a very life-threatening cancer and one of the most difficult types of cancer. Although lung cancer to any organ of the body,… spread out – especially the adrenal glands, liver, brain and bone – specific locations are the most common sites of metastases from it.
Signs and symptoms
It is the most common type of cancer in men and the fifth most common in women, even causes more cancer deaths in women than breast cancer. The incidence of it is a correlation with smoking, with 90 percent of cases as a result of tobacco use. Rare before the early 1930, incidence of lung cancer began to rise during the Decade of 1930, as tobacco was known. Awareness about the dangers of smoking and smoking setting programs effective led to rate cuts of the lung cancer in many developing countries.
Symptoms of it are different according to the exact location of the tumor and the extent of its increase. A person with lung cancer have the following symptoms:
• No symptoms-up to 25% of people who have lung cancer found no symptoms of cancer. In these cases, the cancer is routine is first chest X-ray discovered or performed with computer tomography (CT) for any other reason.
•
• Symptoms related to metastasis (spread to other organs) – lung cancer, which is on the bone has bone cause excruciating pain on sides of participation. Cancer that has spread to the brain can many neurological symptoms that look blurred, headaches, convulsions, confusion or thought processes change included can or the stroke cause symptoms.
• Paraneoplastic symptoms lung cancer is often accompanied by so-called Paraneoplastic syndromes resulting from the manufacture of hormonal substances such as tumor cells, which are released into the blood. Common paraneo plasticsyndrome associated with a type of lung cancer is the production of a hormone called Adrenocorticotrofica hormone (ACTH) of cancer cells leads to the secretion of a different hormone cortisol by the adrenal glands (Cushing’s syndrome).
• Non-specific symptoms witnessed with many cancers, such as lung cancer, non-specific symptoms are weight loss, weakness, and fatigue.It is important to consult a doctor, always when a person develops symptoms with lung cancer, in particular:
• Pain in the chest
• Blood in the sputum Bronchitis
• Unexplained weight loss or tiredness
• Prolonged or repeated respiratory tract infections
• Breathing difficulties such as lack of air or wheezing
• One new permanent cough or the aggravation of an existing chronic cough
How is lung cancer treated?
Its treatments set according to the type of cancer, the stage of the cancer (how far it has spread), age, health condition and additional personal characteristics. There of usually no single treatment for cancer, patients often receive a combination of therapies and palliative care. The most important lung cancer treatments are chemotherapy, surgery and radiation. However, there were also recent developments in the fields of gene therapy, hormonal therapy and immunotherapy.
Surgery
Radiation
Radiotherapy destroys also known as radiation therapy or cancer tumors by focusing high-energy rays on the cancer cells reduce lung. This causes damage to the molecules of the cancer cells, and leads them to commit suicide. Radiation therapy uses high-energy gamma rays, which are emitted by metals such as radium or high-energy x-rays created in a special machine. Radiation can as the main treatment for it, used to kill the remaining cells after surgery or to kill cancer cells, have the Mets.
How can lung cancer be prevented?
Cancers that are certain behaviors in closely related are easier to avoid. Reduced not to smoke choice tobacco or alcohol, for example, the risk of several types of cancer-most especially lung, throat, mouth, and liver cancer. Even if you can stop a current user of tobacco, your chances of getting cancer is still significantly reduce. The most important preventive measure you can take to prevent lung cancer is to quit smoking.
