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 inflammations of the lining in the bronchial tubes, which are responsible for carrying air from and to your lungs are known as bronchitis. It is a respiratory disease and more than a million cases are reported each year. Bronchitis requires medical diagnosis by your healthcare provider and can be chronic or acute. Cold or other respiratory infections can cause acute bronchitis whereas smoking leads to chronic bronchitis. Acute bronchitis usually lasts for few days but with persistent cough. Whereas, chronic bronchitis can be responsible for chronic obstructive pulmonary disease.

Symptoms of bronchitis:
The symptoms common to both acute and chronic bronchitis are given below:
1. Cough which may form mucus
2. Body aches and breathlessness
3. Headaches, blocked nose and sinuses
4. Fever with chills
5. Wheezing

The diagnosis of bronchitis is done by your doctor who will ask you about your cough. Some other questions may include your medical history, about smoking or whether you have had cases of flu or cold recently.

Treatment for bronchitis:
Your doctor will mainly recommend pain relievers and cough syrup along with warm air to breathe mainly at indoors. However your doctor may prescribe the following medications in cases of severe bronchitis:

1. Cough medicine: These medicines will help to remove mucus and irritants from your lungs. Medicines may not be able to suppress the symptoms completely but will give you relief from pain.
2. Bronchodilators: Which clears out the mucus by opening your bronchial tubes.
3. Mucolytics: These helps loosen mucus in the airways and help to cough up sputum.
4. Oxygen therapy: It will help to improve the oxygen intake when you face difficulty in breathing.
5. Therapy: Pulmonary program will include a therapist who would work to improve your breathing.
6. Medicines: Using anti inflammatory medicines to reduce damage to your lungs tissue and to also avoid chronic inflammation.

Prevention of bronchitis:

Acute and chronic bronchitis can be reduced by the following measures; however, they cannot be completely prevented:
1. Avoiding dust, smoke, and air pollution. You can always wear a mask when you are on the road or in traffic.
2. Washing your hands often to avoid germs and infections.
3. Avoiding smoking as it can cause harmful damage to your lungs.

All About Bronchitis

Pulmonary Function Tests or PFTs are a set of tests that are used to determine, measure or observe the functioning of the lungs. The most common pulmonary function tests used are spirometry, gas diffusion, and lung plethysmography. 

Highlights of pulmonary function tests

A spirometry test is used to measure the amount of air inhaled and exhaled. It also measures the amount of time taken to complete a respiration cycle.
A lung plethysmography measures the amount of air in the lungs after the patient has taken a deep breath. It also measures the amount of air that remains in the lungs after the patient has exhaled as much air as possible.
What does a Pulmonary Function Test measure?
Pulmonary function tests would not only check how well the person is breathing but also how effectively the lungs are able to conduct oxygen to the rest of the body. In addition to air flow, these tests would measure the size and volume of the lung and lung diffusion.

These tests can also be used to measure

Total Lung Capacity   the amount of air present in the lungs after breathing in deeply
Forced Vital Capacity   the amount of air that can be exhaled after breathing in deeply
Minute Volume   the amount of air exhaled per minute
Vital Capacity   the total volume of air that can be breathed out after inhaling as much as possible
Tidal Volume   the amount of air inhaled or exhaled when breathing normally
Maximum voluntary ventilation   the amount of air that can be inhaled and exhaled in one minute
Functional Residual Capacity   the amount of air that remains in the lungs when breathing normally
Forced Expiratory Flow   the flow or volume of air during an exhalation
Peak Expiratory Flow Rate   the rate at which a person can exhale
When are Pulmonary Function Tests recommended?
A physician might recommend a patient undergo a PFT as part of a routine physical check-up. This test would be advised if the patient is experiencing any symptoms associated with lung problems or disorders such as asthma, respiratory infections, chronic obstructive pulmonary disease, COPD. A doctor would also use these tests to monitor and check whether a certain treatment prescribed for a lung disease or condition is working effectively.

Pulmonary function tests are safe as they are non-invasive but it is important to follow the instructions of the doctor or technician before, after and during the test. It is important to make your doctor aware of any surgeries, respiratory infections, chest pains or heart attacks that you might have experienced before the test. If you are taking any medications you might need to follow the advice of the doctor as to whether you can take them before the test.

Your doctor would also advice you on how to prepare for the test such as not eating a large meal, avoiding caffeine and wearing loose-fitting clothes. If you have any doubts, concerns or queries discuss them with your doctor.

Pulmonary Function Tests - Why Is It Required?

Bronchial asthma is a medical condition. It happens when the airways of your lungs swell up and become narrow. This limits the amount of air that can pass through the passages and this leads to respiratory distress. Asthma can affect anyone and usually, it starts from childhood.

What are the Symptoms of Bronchial Asthma?
Some common symptoms of bronchial asthma are-

  Wheezing and breathlessness
  Tightness of the chest
  Frequent bouts of coughing which are more common at night or in the early morning, making sleep difficult. 

Bronchial asthma does not go away on its own. It requires treatment.

What is Siddha?
Siddha is a very ancient system of medication and treatment that originated in Tamil Nadu. According to Siddha, the individual is a microcosm of the entire universe. And it is made up of some fundamental elements- earth, air, fire, water and ether as well as three humours- Vata, Pitta and Kapha. An imbalance of these components causes an ailment. So, the chief goal of Siddha is to restore the right balance to root out any illness.

Types of Asthma according to Siddha -
We find mention of asthma in Siddha literature. It is called Eraippu Noi. There are five types of asthma -

  Vazhi Eraippu Noi - Digestive troubles may lead to accumulation of Vata. This is not a grave form of asthma and can easily be cured.

  Iya Eraippu Noi - Exposure to cold climes or freezing winds or being drenched in rain can cause Kapha to build up in the system, which triggers this form of asthma. It is accompanied by symptoms such as the runny nose, nasal congestion, breathing trouble when lying down.

  Iyavazhi Eraippu Noi - Both Vata and Kapha accumulate to trigger this kind of asthma. Its symptoms include breathlessness, bloating, indigestion, disorientation, etc.

  Mukkuttra Eraippu Noi - An imbalance of all three humours- Vata, Pitta and Kapha are the culprits behind mukkuttra Eraippu Noi. A person who has contracted it might experience severe chest pain, constipation and even loss of consciousness.

  Mel nokku Eraippu Noi - This is the gravest form of bronchial asthma and requires extensive treatment.

Treatment of Asthma according to Siddha -

Siddha will first try to understand what kind of imbalance has caused your asthma. The medication depends on the type of asthma. Siddha medicines are made from particular parts of herbs that will induce you to either vomit or defecate to get rid of the excess humour that has accumulated in your body. Thus, the balance of Kapha, Pitta and Vata is restored.

You might also be suggested a few breathing exercises to strengthen your lungs and diaphragm.
Siddha follows a holistic way to curing bronchial asthma and targets it at its source. Unlike allopathic medication, medicines prescribed by Siddha are herbal and have no side effects.

Siddha Approach In Treating Bronchial Asthma!

Sinuses are cavities in our skull behind the nose which spread out in a pattern. These cavities are lined with tissues and mucosal membranes and are essential for our breathing process. Sinusitis is a condition where the tissues within the cavities become inflamed which results in the sinus cavities being blocked due to a buildup of fluid.

What are the conditions that can lead to sinusitis?
Some of the conditions that can cause nasal polyps are explained as follows:

Nasal polyps are small growths of tissue within the lining of the nose which may block the sinuses, resulting in sinusitis.
Common cold is also a culprit which may result in sinusitis
If your septum or the bridge between the holes of the nose is deviated (this condition is referred to as a deviated septum), you may be prone to developing sinusitis.
The lining of the nose may swell in a condition known as allergic rhinitis and cause sinusitis as well.
Types of sinusitis
There are multiple types of sinusitis which may affect people and also on how long they last. The various types of sinusitis are explained below:

Acute sinusitis: This is the most common form of sinusitis that lasts usually between 2 to 4 weeks. It starts with a cold, blocked nose and turns into facial pain that usually starts very suddenly.
Chronic sinusitis: This is a form of sinus infection which can have a debilitating effect on your life and may last for 12 weeks or longer.
Sub-acute sinusitis: This is somewhere between acute and chronic sinusitis and may last from anywhere between 4 to 12 weeks.
Recurrent sinusitis: This form of sinus infections tend to be a variation of acute or sub-acute sinusitis which tends to occur multiple times a year.
Symptoms of sinusitis
The manifestation of the symptoms of sinusitis may be different from person to person and also on the type of sinusitis you are suffering from. However, there are some generic symptoms that are common to all forms which are mentioned as follows:

Smelling senses may be dulled
Facial pain
Congestion accompanied by a cough
Nose may be blocked, stuffy and may also be runny
Other symptoms may also include bad breath, fatigue, or even dental pain
Nasal cavity may have pus and it may drain from time to time
It is best to consult a doctor quickly, if you have been having any of these symptoms. The doctor can prescribe nasal decongestants and antibiotics which can help. If you have chronic or recurrent sinusitis, then more aggressive and advanced treatments may be required.

Sinusitis - Conditions That Lead to It!

Cardiac or Heart Arrhythmia is a condition which results in disruption of heart s normal rhythm. Due to this, the heart may beat too quickly, too slowly or have an irregular rhythm. Though most of the arrhythmias are not harmful but at times they can have serious consequences, which might turn to be fatal. Differences in heart beats can lead to the restriction of blood, that gets pumped around the body, hence causing damage to the brain, heart and other organs of an individual.

Now we would take into account the causes behind the occurrence of this heart condition.

Causes

Interruption to the electrical impulses in any form that lets the heart to contract can result in arrhythmia. A person with a healthy heart should have a heart rate of anywhere between 60-100 beats per minute while the body is at rest.

There are a number of factors which can cause the heart to work inefficiently, which include:

Alcohol Consumption: If you are used to drinking alcohol varying from light to moderate, the chance of irregular heartbeat increases. A recent study has shown that with every drink consumed per day, the risk of atrial fibrillation increased by 8 percent. Men and women both are at equal risk for irregular heartbeat. Irregular heartbeat is caused because drinking leads to damage of the cells, which in turn leads to causing damage in small areas of fibrous tissue within the heart.

Anxiety: Arrhythmia from anxiety is when the heart feels like something happened due to which it tries to overcompensate and beat quickly. This leads to heart skipping a beat, getting squeezed or undergoing heartbeats at a rapid pace.

Excessive Cosumption of Coffee: Caffeine is a stimulant and tends to speed up heart rate, so consuming too much coffee can lead to the problem of arrhythmia.

Deficiency of Magnesium and Potassium: Magnesium and Potassium deficiencies in one s body can cause Arrhythmia. The deficiencies can be caused due to less intake of citrus fruits and vegetables like potatoes, kiwi, papaya etc.

Symptoms

Arrhythmia can produce a broad range of symptoms which affect the proper functioning of heart. Some of the most serious symptoms are:

Fatigue: If you feel that you are getting fatigued quite easily, then it s a clear symptom of arrhythmia.

Dizziness: A sense of dizziness creeps in when you are having the problem of irregular heartbeat.

Lightheadedness: Feeling light on the head is another symptom of Cardiac Arrhythmia, as there is fluctuation in the amount of blood that reaches the brain through the heart.

Treatment Options

Problem of irregular heartbeats, especially if it s on the slower side, can be solved through the placement of certain devices like pacemaker, which can speed up one s heart rate.
Faster heartbeats can be treated through blood-thinning medications, which would help keep threatening blood clots from getting formed.
Doctors can even go for Catheter ablation, wherein they would thread one or more catheters through the blood vessels of one s heart. Electrodes at the catheter tips can make use of extreme heat, cold or radiofrequency energy to damage a small sport of heart tissue and create an electrical block along the path, that s causing one s arrhythmia.
