Lung Cancer – Causes, Treatments, and Prevention

Lung cancer is a condition which begins in the cells that line the lungs. It can also spread to other parts of the body. The most common treatment options are surgery, chemotherapy, and radiation therapy.

Most lung cancer case cancer treatments can’t cure the cancer but can help control it. Your doctor might recommend chemotherapy, radiation therapy or another option based on the type and severity of your lung cancer.

What is lung cancer?

Cancer occurs when cells expand uncontrollably, and then form tumors that spread throughout the entire body. Lung cancer starts in the lungs, and can develop to other organs in the chest or to other body parts. There are two major types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

NSCLC makes up about 80-85% of lung cancer cases. It is less aggressive than SCLC and isn’t likely to cause symptoms at the early stages. NSCLC is further classified according to epithelial cell type, such as squamous-cell carcinoma and Adenocarcinoma. Other less common types are Adenosquamous cancer and adenocarcinoma.

Some people develop a rare form of NSCLC that develops in the cells that line the lungs’ passageways called bronchioles. A rare type of NSCLC called pulmonary adenocarcinoma appears in the lining of the lungs in the mediastinum.

Smoking tobacco is a common cause of SCLC, which is responsible for 15 percent of lung cancers. It develops more quickly than NSCLC and can welding cause lung cancer spread to other areas of the body. This kind of cancer may also cause fluid to accumulate in the chest area around the lungs (pleural effusion). Treatment options for lung cancer can welding cause lung cancer vary depending on the stage at which it is diagnosed.

What causes lung cancer?

The lungs are the cone-shaped organs located in the chest. They release carbon dioxide when you exhale and provide oxygen to your body. Tiny air sacs called alveoli and tubes referred to as bronchi make up the inside of each lung cancer mesothelioma (Recommended Looking at). There is a risk of increasing the risk of developing lung cancer smoking cigarettes, cigars, or pipes, or exposing yourself to secondhand smoke. Other risk factors include a family history of lung cancer or other forms of cancer, suffering from an infection like pneumonia, being diagnosed with a condition called emphysema, or having a medical condition like chronic obstructive respiratory disease (COPD).

Lung cancer is typically caused by bronchioles – small airways which carry oxygen throughout the body. Non-smokers can also be at risk for lung cancer, but the incidence is lower than that of smokers. Daniel Boffa, a Yale Medicine thoracic surgeon, says that if nonsmokers develop lung cancer, the cancer tends to occur within the outer areas of the lungs, in cells that produce mucus, or in the linings of the small airways of the lungs. It can also start in the pleura, which is a thin membrane that protects the exterior of each lung and runs along the chest’s inner cavity.

Doctors make use of a variety tests to detect lung carcinoma and determine if it has spread to other parts of the human body or not. These tests include a physical examination, imaging tests like CT scans, CT scan, MRIs and blood tests such as a complete blood counts (CBC) or an examination of the blood chemical. A Molecular test is a lab technique that makes use of special techniques to detect specific modifications in chromosomes, genes and genes in certain types of lung cancer.

What are the symptoms?

There are a myriad of types of cancer that can be affecting the lung. Non-small cell lung carcinoma and small cell cancer are two of the most common types. More than 80% of lung cancers are non-small cell tumors. It may begin in the lungs or may spread from another part of the body (metastasis). Non-small-cell carcinoma can be classified as a number of kinds of tumors, including Adenocarcinoma squamous cell carcinoma and the adenosquamous carcinoma. Small cell cancer on the other hand is not as common and usually starts in the outer layers of cells that line the lungs. It can also spread to the brain and the bones.

Early lung cancer symptoms are not always evident. If symptoms do develop, they’re usually coughing and chest discomfort. Other signs include fatigue, breathing difficulties and weight loss. These symptoms may also be caused by an illness, so be sure to consult your doctor if you notice any of these symptoms occur.

There are treatment options for the majority types of lung cancer occupational cancer. They can be used in isolation or in combination. The best treatment will depend on the stage and type of cancer. There are also newer types of treatment that could aid patients suffering from lung cancer live longer. Immunotherapy, for example, can assist in controlling the growth of tumors.

What are the treatment options for lung cancer?

Treatments for lung cancer aim to eliminate the cancer or limit its spread or growth. Radiotherapy, surgery and chemotherapy may be used as a whole or in combination. Certain treatments can also enhance your quality-of-life and ease symptoms.

Your doctor will determine the most effective treatment plan for you depending on the nature and location of your lung cancer. If you have early or locally advanced non-small cell lung cancer (NSCLC), surgery may be considered as a first option. Surgery can be paired with radiotherapy and chemotherapy for advanced NSCLC. For a few small tumors, a special technique called stereotactic radiotherapy can be used instead of surgery.

Some people with NSCLC may have mutations that cause their cancer to expand. These cancers can be treated using targeted cancer drugs like the drugs alectinib and osimertinib.

Other types of cancer, such as sarcomas and mesothelioma start in different parts of the body and can spread to the lungs. These are more difficult to treat than NSCLC.

Your doctor may recommend palliative care if your lung cancer has spread to other areas of the body, such as the brain. These treatments can lessen the pain and other symptoms such breathing problems or weight increase. They may include medications such as diet and exercise changes techniques for relaxation and spiritual and lung cancer mesothelioma emotional assistance, as well as other therapies.
