Lung cancer is caused by disorderly growth of uncommon cells which line the air passage, usually starting off in a single or both lungs. The irregular cells do not mature into healthy lung tissue but instead divide speedily and result in tumor formation.

Causes behind lung cancer:

Smoking: This is considered as the most significant source of lung cancer. As reported by multiple researches and studies, cigarettes contain over 4,000 chemicals, most of which are cancer causing agents. Active smoking is one of the major causes of lung cancer but what may come to you as a surprise is that extended periods of passive smoking is also a major factor.
Pollution and Exposure: There is high risk of lung cancer development when there is occupational exposure to pollution by chemicals released from industrial factories. Chemical exposure of this kind refers to prolonged exposure over quite few months or years. Some examples of these chemicals are asbestos, diesel exhaust among many others.
Radioactive Gas: Radioactive gases naturally occur in small masses present in all soils and rocks. However, if you breathe in radioactive gases your lungs will damage and may cause the development of abnormal tissue which can cause lung cancer.
Family history: A family history of cancer, especially lung cancer will also put you at high risk of developing lung cancer.
Treatment methods of lung cancer:

Chemotherapy: Chemotherapy is a method in which drugs are injected through veins in your arm (intravenously) or orally or in a combination of both. These drugs kill cancer cells and help to stop it from spreading any further as well.
Clinical Trials: These trials are experimental lung cancer treatment studies. You may have to try out this clinical therapy if other treatment methods aren t working and only if you are accepted into it.
Surgery: A surgeon will help remove affected areas of the lung including cancerous tumors via surgery. The surgeon may need to remove parts of the lung along with the cancerous growth. In certain cases, one side of the lung may also be completely removed to stop the spread of the malignant tissue.
Radiation Therapy: This is a therapy where high energy electromagnetic waves are passed through your body to destroy cancer cells with the help of high-powered energy beams.
Can you prevent lung cancer?

Nutrition -- A  healthy diet with lots of fruits and vegetables may also help reduce your risk of lung cancer. Some evidence suggests that a diet high in fruits and vegetables may help protect against lung cancer in both smokers and non-smokers. But any positive effect of fruits and vegetables on lung cancer risk would be much less than the increased risk from smoking.
Exercise -- Even moderate amounts of exercise can aid in lung cancer prevention. Studies suggest that even something as simple as gardening twice a week is associated with a lower risk of developing lung cancer.
Smoking Habits -- If you stop smoking before a cancer develops, your damaged lung tissue gradually starts to repair itself. No matter what your age or how long you ve smoked, quitting may lower your risk of lung cancer and help you live longer. 
Avoidance of Air Pollution -- Long-term exposure to ambient air pollution and, in particular, particulate matter with absorbed polycyclic aromatic hydrocarbons and other genotoxic chemicals has been suspected to increase the risk for lung cancer. So, avoid air pollution as much as possible.

Lung Cancer - Ways You Can Prevent It!

As much as you want to avoid, there are things you have no control over. Lung cancer (Bronchogenic Carcinomas) is one such nemesis that can throw life in shambles. The malignant tumor that originates in the lungs slowly spreads onto the other distinct and vital organs as well. Thought to be mostly affecting men who are chain smokers and into severe tobacco consumption, incidences of lung cancer in women are rising at an alarming rate over the past few years. Non-smokers may also be susceptible (to a lesser extent though) to lung cancer.

Lung cancer can be either

Non-small cell lung cancers: The NSCLC, accounting for ~85% of the lung cancer is one of the most common types of lung cancer affecting people, NSCLC may further be divided into
Adenocarcinoma: This type of NSCLC originates mostly in the peripheral regions of the lungs and may affect (spread) the lymph nodes. Non-smokers and women are mostly at the receiving end (other than the chain smokers).
Squamous Cell Carcinoma: Also known as Epidermoid Carcinoma, often affects men, epidermoid carcinoma may originate in the tissues that line the bronchial tubes. The lymph nodes are often affected by Epidermoid Carcinoma.
Large-cell Undifferentiated Carcinoma: The point of origin of large-cell undifferentiated carcinoma is the surface of the lungs. They have a higher probability of spreading to the lymph nodes.
Bronchioalveolar Carcinoma: Though rare, bronchioalveolar carcinoma originates close to the air sacs.
Small Cell Lung Cancer (SCLC, accounting for ~25% of the lung cancer): As the name suggests, SCLC is marked by the rapid proliferation of small cells into large malignant tumors. SCLC can move throughout the body (affecting vital organs).
Radiotherapy to treat Lung cancer:
Radiotherapy plays a pivotal role in the treatment of lung cancer. The radiation therapy is mainly of two types

External beam radiation therapy (EBRT)
Internal radiation therapy (Brachytherapy)
In external beam radiation therapy, high-energy rays are focused on the cancer cells (thereby resulting in the apoptosis of the cancer cells) externally, from outside the body. EBRT is particularly helpful in case of Non-small cell lung cancers.

The EBRT may be of the following types

3D-CRT (Three-dimensional conformal radiation therapy): An advanced radiation therapy, 3D-CRT accurately marks the position of the cancer cells (using advanced computers). The treatment ensures minimum damage to the other healthy cells and tissues (energy rays are directed at the affected cells from different positions).
SBRT (Stereotactic body radiation therapy): This is a radiation therapy used in the treatment of NSCLC, when it is at a nascent stage.
IMRT (Intensity modulated radiation therapy): As the name suggests, in IMRT, the intensity of the radiation reaching the normal tissues and cells can be modulated. Like 3D-CRT, the radiation in IMRT is directed from different angles (for maximum results).
Internal radiation therapy (Brachytherapy): This type of radiation therapy is generally used to deal with lung cancers that tend to block the airways. In this therapy, the radiation process is carried out through a narrow tube, thereby, shrinking and collapsing the tumor.
The effect, dosage, and duration of radiation therapy depend on the stage and severity of the condition. In some cases, radiation therapy may be given together with chemotherapy.

Radiotherapy - Is It Beneficial For Lung Cancer?

Cancer like most other diseases has the best rates of recovery with early detection and intervention. As there are no regular health screenings for blood cancer, only the awareness about the early warning signs can save your life. November is designated as the Lung Cancer Awareness Month, to ensure every individual is equipped to fight against lung cancer right from the start. Here are 4 vital facts you must know to win your fight against blood cancer.
Lung cancer is also known as pulmonary carcinoma or cancer of the lung. It occurs when DNA mutations develop in the cells/ tissues of the lungs leading up to uncontrolled growth in the tissues of the lung. By far, it is known to be the most common cancer in Asia.

1. Type: lung cancers can present as one of the following types: 

Non-Small Cell Lung Cancer (NSCLC): Most common type of lung cancer and constitutes nearly 85% of all lung cancers. The sub-types of NSCLC are as follows:
Large cell carcinoma
Squamous cell carcinoma (SqCC) (Epidermoid)
Adenocarcinoma   accounts for majority of the NSCLC.
Small Cell Lung Cancer (SCLC): It is also known as oat meal cancer and tends to spread (metastasize) quickly. This constitutes about 15% of the lung cancers.
Mesothelioma: It is a rare cancer that develops in the mesothelial cells of the pleural or peritoneal surfaces. It usually arises in the pleural membrane lining the lungs, known as pleural mesothelioma. One that arises from the peritoneum is called the peritoneal mesothelioma and the one that arises from the pericardium is known as pericardial mesothelioma. Lastly, it can also arise from the tunica vaginalis known as testicular mesothelioma. People working with or prior exposure to asbestos are mostly at risk of developing mesothelioma. The latency period between time of exposure and development of mesothelioma can be somewhere between 20 to 40 years. Maximum of the patients who develop mesothelioma are men.
2. Gender: It affects the male populace predominantly. It is more common in men than in women and in those of lower economic status. However, the incidence of lung cancer, in women too, is on the rise of late.

3. Etiology: Cigarette/ Tobacco smoking remains the most important cause of lung cancer accounting for 85   90% of the cases. Incidence/ risk is proportionate to the number of cigarettes smoked irrespective of the age. Also, environmental toxins including smoke from burning black tar, exhaust gases from automobiles etc. too contribute actively to various lung diseases including cancer. People working in asbestos manufacturing factories who are exposed to asbestos dust are also likely to get lung cancer. Tuberculosis too is an additive risk factor. Again, people who have received ionizing radiation especially to treat Hodgkin Lymphoma or other malignancies also run the risk of developing lung cancer. Above-mentioned causes apart, genetic factors may also play a role.

4. Features: Lung cancer clinically presents in the following ways mainly. Signs & symptoms of malignant mesothelioma are as enumerated below

Difficult/ labored breathing (Dyspnea)
Chest pain
Palpable chest wall mass
Discordant chest wall expansion
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Night sweats
Signs & symptoms of non-small cell lung cancer (NSCLC) are as enumerated below. Majority of patients are symptomatic at diagnosis

Chronic cough
Difficult/ labored breathing (Dyspnea)
Chest pain
Blood stained sputum (Hemoptysis)
Hoarseness
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Weakness
Bone pain
Pleural or pericardial effusion
Superior vena cava syndrome
Brachial plexopathy
Neurologic pain
Hypercalcemia of malignancy
Signs & symptoms of small cell lung cancer (SCLC) are as enumerated below

Symptoms as per the points 8   18 depicted above for NSCLC are applicable for SCLC as well. Additionally, patients suffering from SCLC may have:

Fever associated with chest infections like bronchitis/ pneumonia that refuse to go away or keep coming back
Horner syndrome
Paraneoplastic syndromes including encephalitis/ sub-acute sensory neuropathy, hyponatremia, acromegaly, cancer associated retinopathy, ectopic corticotropic syndrome etc all.
5. Screening: is generally recommended for asymptomatic/ symptomatic populations as surveillance for high-risk individuals   who are either current or former smokers (quit smoking within the last 15 years) have at least a 30 pack-year smoking history and those who do not have any prior history of lung cancer. The goal of screening, as usual, is to be able to detect & diagnose lung cancer at an early stage which is potentially curable. It is mostly radiologic with a low dose helical computed tomography (CT) scan being more effective in detecting early-stage lung cancer than a chest radiograph can.

6. Diagnosis: Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for an accurate diagnosis. Following are the diagnostics employed mainly:

Blood: Hb may be low, TLC, ESR and polymorphs increased. Adenocarcinomas are likely to express thyroid transcription factor 1 (TTF-1) or carcinoembryonic antigen (CEA). On the other hand, mesotheliomas are likely to express Wilms Tumor -1 (WT-1) protein and Calretinin.
Imaging: Thoracoscopy, Bronchoscopy, X-Ray, CT Scan etc all. Positron Emission Tomography (PET) / CT scan and Magnetic Resonance Imaging (MRI) scan help detect metastasis if any.
Biopsy: It clinches the histologic diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, chemotherapy and radiotherapy as contextually appropriate. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as would be feasible contextually.

8. Prognosis: Preventive measures, earlier diagnosis and right early treatment are key for effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for early-stage lung cancer are more. The cure/ recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all. The primary determinant of prognosis in NSCLC is the stage at which the cancer is diagnosed. For non-metastatic cancers, however, it is the nodal status that determines the stage and hence the prognosis.

9. Prevention: Rightly said, prevention is always a better choice. Cigarette smoking is to be avoided by all means as it is the single major cause of lung cancer. Even exposure to cigarette smoke (passive or secondhand) is also an established cause of lung cancer and is known to increase the risk of lung cancer in non-smokers as well. Preventing exposure to secondhand smoke can be helpful in decreasing the incidence and mortality of primary lung cancers. Above-mentioned apart, other important risk factors such as exposure to ionizing radiation, environmental carcinogens like smoke from burning black tar, exhaust gases from automobiles, outdoor air pollution, and occupational exposure to asbestos, arsenic, beryllium, nickel, cadmium, chromium etc all too are known to increase the risk for lung cancer and mortality thereof. In fact, cigarette smoking is known to potentiate the effect and hence the lung cancer risk of many of the above-mentioned carcinogens, multi-fold, in smokers. Thus, either eliminating or reducing the exposure to the above-mentioned carcinogens can lead to a decrease in the risk of lung cancer and incidences thereof. Furthermore, randomized clinical trials indicate that high-intensity smokers (only) who take supplementation of beta-carotene have an increased risk/ incidence of lung cancer. Vitamin E supplementation, on the other hand, does not affect the risk of lung cancer as indicated by the trials.

Lung Cancer Awareness Month - Lung Cancer In Nutshell!

Lungs are the most important organ of our body that has the responsibility of taking in the oxygen and releasing out carbon dioxide. When cancer develops in it, the entire body gets imbalanced. Lung cancer leads to more death than any other type of cancer, which is why identifying the symptoms and knowing the causes are instrumental in obtaining a timely diagnosis as well as in prevention of lung cancer.

Symptoms of Lung Cancer

In the early stages:

Persistent coughing

Chest pain

Bleeding

Fatigue

Loss of appetite

Sudden weight loss

Headaches

Coughing up blood

In the later stages:

Bone pain

Joint pain

Facial paralysis

Neck swelling

Blood clotting

Weakness

Sever chest pain

Causes of Lung Cancer:

Smoking: People who smoke are more prone to lung cancer. With the increase in the number of cigarettes you smoke, your chances of getting lung cancer increase too. People who don't smoke but are surrounded by the smokers also have high chances of being affected by this form of cancer.
Exposure to Asbestos: Asbestos is a group of mineral, which is present naturally in the environment. Lung cancer can occur due to the inhalation and ingestion of asbestos fibers.
Exposure to Ranon Gas: Ranon is a radioactive gas, which is formed naturally on decaying of radioactive elements. It is found in low levels in the air that we breathe and the water that we drink. Consumption of air and water having this gas leads to lung cancer.
High Levels of Air Pollution: Presence of high levels of dust particles and pollutants in the air that we breathe can cause lung cancer. 1-2% of lung cancer is caused because of it.
High Levels of Arsenic in Drinking Water: Consuming water with arsenic content is harmful as it directly affects the lungs and when the arsenic content is too high, it may lead to lung cancer.
Exposure to Chemicals: Exposure to certain chemicals like uranium, coal products, gasoline, diesel exhaust and mustard gas can also cause lung cancer.
Family History of Lung Cancer: Chances of getting lung cancer increase if your parents, child or siblings are already prone to lung cancer. In case you have a concern or query you can always consult an expert & get answers to your questions!

Lung Cancer - Symptoms & Causes! 

Lungs are very important organs of your body as they play a pivotal role in respiration. Lung cancer refers to the gradual development of cancerous cells in the lungs. Many common symptoms can help you to identify lung cancer. They are stated below:

A) persistent cough
B) change in your voice
C) pain in the chest region
D) breathing problem
E) fatigue
F) loss of weight and appetite
G) sometimes a person may also cough up blood
H) cough accompanied by a wheezing sound

Lung cancer is very fatal and has less chances of getting cured. However, ayurveda offers effective and natural remedies for treating lung cancer. They are mentioned as follows:

1. Practice breathing exercises regularly: breathing exercises can help you to deal with the problem of lung cancer in an effective manner.

2. Quit smoking and avoid drinking alcohol: this is absolutely essential for treating lung cancer. Both smoking and consuming alcohol can cause severe damage to your lungs.

3. Practice meditation. According to ayurveda, meditation is known to have great healing powers for any health problem. This can help you to cope up with cancer as well.

4. Avoid junk foods and carbonated drinks: consuming these foods frequently can worsen your condition.

5. Massage therapy: sometimes massage therapy can work wonders in ayurveda. Massaging certain essential oils can be very helpful.

6. Aromatherapy: aromatherapy can also prove to be effective in treating lung cancer. It is a procedure in which essential oils are not only used for massaging your body but also for inhaling.

7. Ayurvedic herbs: there are many ayurvedic medicines and herbs also which can treat lung cancer efficiently.

Since lung cancer involves very less survival rate, it is of utmost importance that you go the doctor immediately once you start noticing any of the above mentioned symptoms.

Treating Lung Cancer With Ayurveda

Pulmonary diseases are some of the most commonly experienced health conditions all over the world. Millions of people suffer due to various causes including genetics, smoking, pollutants and infection. Now lungs are one of the most important and complex organs of the body. They are the apparatus through which oxygen enters and carbon dioxide gets expelled. 

Lungs expand and contract on a constant basis to ensure that we can breathe properly. Let us find out more about lung or pulmonary diseases.

Asthma: This is one of the most common and potentially fatal conditions that affect children and adults. It grips the airways formed by the bronchi which branch off into smaller tubes from the main trachea that holds them. This condition causes inflammation, and even spasms, which can lead to wheezing and breathlessness. The main triggers of asthma attacks include allergies, infections and pollutants that may escape into the airways.
COPD: This is also known as Chronic Obstructive Pulmonary Disorder. It is an umbrella term used for various lung conditions that cause breathing difficulties due to an obstruction of the airways. Chronic bronchitis is one of the conditions that falls under COPD, and is usually characterised by persistent, hacking coughs.
Cystic Fibrosis: This is another condition that affects the airways by causing poor passage of mucus from the bronchial tubes. This condition is a genetic one where the mucus that gathers eventually becomes a lung infection.
Pneumonia: This is a condition that causes an infection in the alveoli, which are the tiny tubes that the airways branch into. These are air sacs that can catch myriad infections like pneumonia.
Tuberculosis: This is also a kind of pneumonia, which is caused by bacteria called Mycobacterium Tuberculosis. This condition usually attacks the air sacs of the lungs and can be a potentially fatal disease if it is not treated on time. The patient will require immediate hospitalisation.
Pulmonary Edema: This condition is caused by fluid leaks from the tiny blood vessels into the surrounding air sacs within the lungs. It can also be caused due to heart failure as well as back pressure which falls on the lungs. Direct injury to the lungs can also lead to this condition.
Lung Cancer: This is a fatal disease which can be found in any part of the lungs. It has many forms and the type as well as the location usually determines the kind of treatment option that will be followed.
Acute Respiratory Distress Syndrome: When the lungs suffer a sudden injury which is usually caused by a bout of serious illness, it is called ARDS. Treatment involves the use of life support ventilation.
