Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.

Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.

What Causes Lung Cancer?

The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.

Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).

Lung Cancer Symptoms

Early symptoms and signs of lung cancer

There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:

Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
Fatigue: It is common to feel weak or excessively tired.
Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer

Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:

Bone pain
Swelling of the face, arms or neck
Headaches, dizziness or limbs that become weak or numb
Jaundice
Lumps in the neck or collar-bone region
Treatment

Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.

Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.

Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

Lung Cancer: Causes, Symptoms and Treatments

International Childhood Cancer Day is celebrated annually on 15 February to raise awareness and to express support for children and adolescents with cancer, survivors and their families.

Why is Cancer the biggest Threat to the YOUNG in India?

There are fewer Indians who have successfully battled Cancer and have emerged successful. Yuvraj Singh, the legendary cricketer, who was diagnosed with a rare cancer at 29, survived due to an early detection. Cancer cases in India are not as many as they are in the developed world. However, due to late detection the survival rate in the country is far worse. Particularly, we are losing our youth to Cancer. Most tobacco (pan masala) related cancers and child cancers go undetected until very late.

Few cancers like cervical cancer and breast cancer which affect women of any age, are curable, however, due to lack of awareness and timely screening, many Indian women succumb to these cancers. The most common sites for cancer among men are lung, prostate, colon, rectum, stomach and liver while that among women are breast, colon, rectum, lung, cervix and stomach.

In proportion to our population, we lack the right infrastructure nationwide. esp in the northern and north eastern region, there is a dearth of good cancer facilities, where radiation, care or treatment can be given. Not even one third of cancer patients are alive beyond 5 years after their diagnosis in India, and about 71% of cancer deaths occur in patients in their prime productive years   between the ages of 30 to 69 years.

 Most Indians believe that cancer is generally incurable and that it should be kept secret from neighbors and family.  -  Dr Paul Goss, MD, Harvard University.

All these factors have contributed to a very high mortality rate. No wonder Cancer is dreaded in the country. Investment, infrastructure, lifestyles as well as mindsets need to change if we were to contain the Cancer mortality rate. While you need to watch out for early signs of cancer, here are the lifestyle changes every individual esp. all youth must adopt to avoid cancer.

Avoid Tobacco - both smoking and chewing.

Reduce alcohol intake - Save your organs from deteriorating.

Limit UV ray exposure from the sun - Keeps your skin safe.

Maintain a healthy diet - Include foods rich in Vitamins, minerals and fiber which nourish your body and build immunity.

Increase your level of fitness - Maintain a good bodyweight. Additional flab invites a host of troubles, that includes variety of cancers.

Seeking regular medical checkup or screening - This is the only way to prevent and get detected early on.

International Childhood Cancer Day - Why Cancer Is A Threat For Young?

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!

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!

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.
