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!

The sound of the word cancer can be really traumatic and the fact the one may most of the time be unaware of this condition can be hard to handle. The same is the situation in the case of lung cancer as it does not produce any remarkable signs and symptoms in its early stages. However, there are ways in which you can be aware of this life-threatening ailment. Here are some tell-tale signs of an early stage of lung cancer:

A stubborn cough:
Beware when a cough is lingering on for long with no sign of relief. When a cough is related to cold and respiratory infection, it will subside within a week or so. But in case the cough is persistent, it can be a symptom of lung cancer. You should never dismiss a stubborn cough regardless of whether it is dry or producing mucus. You should talk to a doctor right away as he can check the lungs and may order for other tests to determine whether you have cancer.

Breathing problems:
Becoming easily winded or shortness of breath is considered the most prominent symptoms of lung cancers. This may occur when cancer blocks or inhibit the airway or when the fluid from the tumor starts building up in the chest. If you find that it is becoming difficult for you to breathe in doing tasks that you found easy before, you should not ignore it.



Wheezing:
When the airways become inflamed, blocked or constricted, then the lungs would produce a wheezing and whistling sound while breathing. It can be associated with a host of other causes that are easily treatable but could also be due to lung cancer.

Headache:
Even though headaches are considered one of the most common health problems, if there is a persistent headache, then it could be a sign that lung cancer has spread to the brain. It is important to understand that all headaches are not associated with the brain metastases. There are times when the lung cancer creates pressure on the superior vena cava which is in charge of supplying blood to the upper part of the brain. This pressure can also lead to headaches.

Pain in the bone:
If the lung cancer has spread to the other parts of the body, then it may produce mild pain in the back and other parts of the body. It tends to become worse during the night when you are resting on your back. But it can be difficult for a commoner to differentiate between muscle and bone pain. In case you are suffering from bone pain, you will see that it is becoming worse with movement. Moreover, lung cancer is also associated with pain in the shoulder, neck, and arm even though it is very rare. You should be very attentive to the pain and aches in the body and consult with an expert at the earliest.

You can easily combat lung cancer if diagnosed and treatment is started in its early stages. In case you have a concern or query you can always consult an expert & get answers to your questions!

Five Signs That You Might Be Suffering From Early Stage Lung Cancer!

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?

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.

All About Pulmonary Diseases

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! 

Lung cancer is the cancer killer of both men and women in the world. When you think of risk factors for lung cancer, what comes to mind? Most of us think about the risk associated with smoking cigarettes, but did you know that air pollution can also cause lung cancer? Overwhelming evidence shows that particle pollution in the outdoor air we breathe like that coming from vehicle exhaust, coal-fired power plants and other industrial sources - can cause lung cancer. Particle pollution increases the risk of dying early, heart disease and asthma attacks, and it can also interfere with the growth and function of the lungs. 

What is Particle Pollution?

Particle pollution is a mix of tiny solid and liquid particles in the air and can be made up of a number of components, such as acids, organic chemicals, metals, soil and dust particles. It can be emitted directly from wood stoves, forest fires, vehicles and other sources, and it can also form from other types of pollution that come from sources like power plants. 

Why does particle pollution harm our bodies?

While breathing in larger sizes of particle pollution can be harmful to our health, smaller particles are more dangerous. Bigger particles can irritate your eyes, nose and throat, but our natural defenses help us to cough or sneeze them out of our bodies. Unfortunately, those defenses don't keep out smaller particles, which get trapped deep in the lungs and can even get into the bloodstream, causing damage to our health.



Who is most at risk?

As for who is at risk for health problems from breathing in particle pollution. Those who live where particle pollution levels are high is at risk. Some people face higher risk, including children, the elderly, people with lung and heart disease and diabetes, people with low incomes, and people who work or exercise outdoors.

How do we protect ourselves from particle pollution?

Check the air quality index forecast for the day and limit your activity if pollution levels are high. Avoid exercising along heavily traveled highways regardless of the overall forecast.

As individuals, we can play our part in reducing air pollution levels by trying to avoid creating more of it. Choosing  active travel  options where possible, like walking and cycling, can help reduce pollution levels from transport and is also a great way to be more active, which is linked to a reduced risk of cancer and other diseases. In case you have a concern or query you can always consult an expert & get answers to your questions!
