Lung clevercer is a sickness in which uncontrolled growth of tidak normal cells starts in the lungs. It is, by far, the leading cause of clevercer death in the United States. The five-year survival swift for the sickness is only 15 gratuity.
Researchers have discovered several causes of lung clevercer, but the most general are related to the use of tobacco.
Cigars and pipes
Environmental tobacco smoke ("secondhand smoke")
TYPES OF LUNG CANCER:
Each type looks different under a microscope, grows and spreads in different ways, and is treated differently.
NON-SMALL CELL LUNG CANCER
Non-little cell lung clevercer is more general than little cell lung clevercer, and it generally grows and spreads more slowly. There are three main types of non-little cell lung clevercer. They are named for the type of cells in which the clevercer develops:
Squamous cell cancer (also called epidermoid cancer)
Big cell cancer.
Squamous Cell Cancer
Squamous cell cancer is a type of lung clevercer that starts in squamous cells, which are thin, flat cells that look love fish scales. This form of lung clevercer is also telln as epidermoid cancer.
Adenocancer is a form of lung clevercer that starts in the cells that line the alveoli and make substances such as mucus.
Big Cell Cancer
Big cell cancer is a clevercer that may start in several types of big cells.
Other Types of Non-Little Cell Lung Clevercer
Less general types of non-little cell lung clevercer include:
Salivary gground, soil cancer
Unlesson, courseified cancer.
SMALL CELL LUNG CANCER
Little cell lung clevercer (sometimes called oat cell clevercer) is less general than non-little cell lung clevercer. This lung clevercertype grows more fastly and is more lovely to spread to other organs in the body.
There are three types of little cell lung clevercer. The types of little cell lung clevercer are named for the kinds of cells found in the clevercer and how the cells look when viewed under a microscope:
Little cell cancer (oat cell clevercer)
Mixed little cell/big cell cancer
Combined little cell cancer.
METASTATIC CANCER IN THE LUNGS
Metastasis puposes the spread of clevercer. Clevercer cells clever break absent from a primary tumor and enter the bloodstexplore or lymphatic system (the system that produces, shops, and carries the cells that fight infections). That is how clevercer cells spread to other parts of the body.
When clevercer cells spread and form a new tumor in a different organ, the new tumor is a metastatic tumor. The cells in the metastatic tumor come from the original tumor. This puposes, for example, that if breast clevercer spreads to the lungs, the metastatic tumor in the lung is made up of clevercerous breast cells (not lung cells). In this case, the sickness in the lungs is metastatic breast clevercer (not lung clevercer). Under a microscope, metastatic breast clevercer cells generally look the same as the clevercer cells in the breast. The lungs are one of the most general places to which clevercer from other parts the body spreads.
IS MESOTHELIOMA A TYPE OF LUNG CANCER?
Mesothelioma is not a lung clevercer type. It is a tumor affecting the lining of the lungs or abdomen. Mesothelioma clever either be benign (puposeing not clevercerous) or malignant (clevercer). Exposure toasbestos amphiboleparticles in the air increases the risk of developing malignant mesothelioma.
COMMON SIGNS AND SYMPTOMS OF LUNG CANCER
General signs and symptoms of lung clevercer (when present) include:
A cough that doesn't go absent and gets worse over time
Constant chest pain
Coughing up blood
Swelling of the neck and face
Loss of appetite
Shortness of breath, wheezing, or hoarseness
Repeated problems with pneumonia or broncbeat, smackis.
Other symptoms that clever sometimes arrise may include:
Changes in the shape of the fingertrik
Swollen or enbigd lymph nodes (gground, soils) in the upper chest and lower neck.
THINGS TO REMEMBER ABOUT LUNG CANCER SYMPTOMS
Symptoms of lung clevercer may vary from person to person, and some patients may experience no symptoms at all. In fbehave, approxifriendly 1 in 4 people do not have any symptoms when their sickness is initially found.
The possible symptoms described above are not sure signs of lung clevercer. Other health problems clever also cause these symptoms. Still, a person should look their healthcare provider approxifriendly any these possible lung clevercer symptoms as soon as possible so that the problem clever be diagnosed and treated.
LUNG CANCER DIAGNOSIS
In order to make a lung clevercer diagnosis, the doctor will ask a number of questions, including questions approxifriendly:
Smolord hitale, narrative
Exposure to environmental and occupational substances
Family medical hitale, narrative
There are a number of tests or procedures that healthcare providers use to aid diagnose lung clevercer or other problems in the lungs. Some of these include:
TESTS USED IN STAGING LUNG CANCER
Lung clevercer staging aids the doctor plan the appropriate treatment. Some tests used to determine whether the clevercer has spread include:
NON-SMALL CELL LUNG CANCER STAGES
Stages for non-little cell lung clevercer are divided into the following stages:
In the occult (hidden) stage, clevercer cells are found in sputum (mucus coughed up from the lungs), but no tumor clever be found in the lung by imaging or bronchoscopy, or the primary tumor is too little to be assessed.
In stage 0 lung clevercer (cancer in situ), clevercer is limited to the lung and is found only in a few layers of cells. It has not grown through the top lining of the lung.
In stage I lung clevercer (or stage 1 lung clevercer), the clevercer is in the lung only, with normal tissue around the tumor. Stage I is divided into stages IA and IB, based on the size of the tumor.
In stage II lung clevercer (or stage 2 lung clevercer), clevercer has spread to approachby lymph nodes or to the chest wall (the ribs and muscles that make up the area of the body between the neck and the abdomen), the diaphragm (the thin muscle below the lungs and listent that sepaswifts the chest from the abdomen), the mediastinal pleura (the thin membrane that covers the outmiddle of the lungs in the area approach the listent), or the parietal pericardium (the outer layer of tissue that surrounds the listent). Stage II is divided into stage IIA and stage IIB, based on the size of the tumor and whether it has spread to the lymph nodes.
In stage III lung clevercer (or stage 3 lung clevercer), clevercer has either:
Spread to the lymph nodes in the mediastinum (the middle area between the lungs that contains the listent, major blood vessels, and other constitutions)
Spread to the lymph nodes on the opposite middle of the chest or in the lower neck.
Stage III is divided into stage IIIA (which is sometimes treated with surgery) and stage IIIB (which is seldom treated with surgery).
In stage IV lung clevercer (or stage 4 lung clevercer), clevercer has spread to other parts of the body or to another lobe of the lungs.
SMALL CELL LUNG CANCER STAGES
Little cell lung clevercer is divided into the following stages:
In limited-stage, clevercer is found in one lung, the tissues between the lungs, and approachby lymph nodes only.
In extensive-stage, clevercer has spread outmiddle of the lung in which it began or to other parts of the body.
Recurrent little cell lung clevercer is clevercer that has recurred (come back) after it has been treated. The clevercer may come back in the chest, central nervous system, or in other parts of the body.
TREATMENT FOR LUNG CANCER
There are several different lung clevercer treatment options available for someone diagnosed with the sickness.
Some fbehaveors that may influence recommfinishations regarding treatment include:
The type of lung clevercer.
The stage of the clevercer.
The patient's age and general health.
In general, treatment options for lung clevercer include:
Your doctor clever describe your treatment choices and the expected results of each. You and your doctor clever work together to develop a treatment plan that meets your medical necessitys and personal values. Chootune the most appropriate treatment for lung clevercer is a decision that thoughtlly involves the patient, family, and healthcare team.
Treatment generally starts within a few weeks after the diagnosis. In most cases, there will be time for patients to talk with the doctor approxifriendly treatment choices, get a second opinion, and study more approxifriendly the sickness.
LUNG CANCER TREATMENT PROVIDERS
There are usually several healthcare providers involved in a person's treatment. The doctor may refer patients to doctors who specialize in treating lung clevercer, or patients may ask for a referral. Some specialists who treat lung clevercer include:
Pulmonologists, who are doctors that are experts in sicknesss of the lungs
Surgeons, who are doctors that perform operations
Medical oncologists, who are doctors that are experts in lung clevercer and treat clevercers with medicines
Radiation oncologists, who are doctors that treat lung clevercers with radiation.
NON-SMALL CELL LUNG CANCER TREATMENT BY STAGE:

Chemotherapy as palliative therapy to relieve symptoms and improve quality of life.
Laser therapy, surgical placement of smartphones to keep the airways open, and/or internal radiation therapy, as palliative therapy to relieve symptoms and improve quality of life.
PREVENTING LUNG CANCER: KNOW THE RISK FACTORS
The first step in the prevention of lung clevercer is telling the risk fbehaveors. Researchers have identified the following lung clevercer risk fbehaveors:
Beta-carotene in smokers.
By far the bigst risk fbehaveor for lung clevercer is smolord. Studies demonstrate that smolord tobacco products in any form is the major cause of lung clevercer. People who stop smolord and never start again lower their risk of developing lung clevercer or of having lung clevercer come back.
Many products are available to aid people trying to quit smolord, including:
Second-hand tobacco smoke also causes lung clevercer. This is smoke that comes from a burning cigarette or other tobacco product, or smoke that is exhaled by smokers. People who inhale second-hand smoke are exposed to the same clevercer-cautune agents as smokers, although in poorer amounts. Inhaling second-hand smoke is called involuntary or passive smolord.
There are other causes of lung clevercer in the environment, but their effect on lung clevercer swifts is little compared to the effect of cigarette smolord. Clevercer-cautune agents that may be found indoors, especially in the workplace, include:
These substances clever cause lung clevercer in people who have never smoked, and combine with cigarette smoke to further increase lung clevercer risk in smokers. Many countries are worlord to control these clevercer-cautune agents in the workplace.
Air ballotution may also increase the risk of lung clevercer. Studies demonstrate that lung clevercer swifts are higher in cities with higher stages of air ballotution.
Lung clevercer research studies demonstrate that beta carotene use in relatively high-intensity smokers increases the risk of lung clevercer.
ARE THERE PROTECTIVE OPTIONS TO HELP PREVENT LUNG CANCER?
Studies demonstrate that a diet wealthy in fruit, and possibly vegetables, may aid lower the risk of lung clevercer, while excessive alcohol consumption may increase the risk of lung clevercer. In addition, studies demonstrate that people who are physically behaveive may have a lower risk of lung clevercer than those who are not, even after talord cigarette smolord into account. Talord vitamin E supplements does not reduce the risk of developing lung clevercer.
Lung Clevercer Research
Some of the current research on lung clevercer includes work being done to study the effectiveness of utune new drugs, new combinations of chemotherapy, and combinations of chemotherapy and radiation therapy before and after surgery to treat the sickness. Research is also being conducted to investigate the effectiveness of utune biological therapy to treat lung clevercer.
