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!

Whooping Cough (another name for Pertussis) can be termed as an infection to the respiratory system caused by the bacterium Bordetella Pertussis (B. pertussis). It generally affects infants (below one year of age) and who have not yet been immunized; also kids between 11 to 18 years of age whose immunity graphs are on a downward spiral.

What are the Signs and Symptoms?
Initially, whooping cough produces signs and symptoms that may just seem to overlap with those exhibited during the average cough and cold; mild coughing, sneezing, runny nose, low fever, etc. These persist for about a week or two and then slowly, there is the onset of the dry, irritating cough which again turns to prolonged coughing spells. The child s face may seem flushed with a purple hue. The child may also vomit or make the distinctive whooping sound at the end of one such spell. Breathing difficulty can be another issue.

What is the Diagnosis?
The doctor performs an initial check-up followed by tests of mucus sample from the nose or throat. The mucus is checked for the presence of the Bordetella pertussis bacteria. To make a more thorough diagnosis, a blood test is also advisable.

What is the Treatment?
Hospitalisation might be required in case of acute distress. Respiratory support may also be provided if required. If there is intense dehydration, intravenous (IV) fluids may also be administered. As this disease is on account of a bacterial infection, antibiotics will be needed. But these will just treat the immediate effects and the cough cannot be completely done away with.
What can be the Possible Complications?

The possible immediate complications include:

Brain Damage
Pneumonia
Convulsion
Haemorrhaging in the brain
What can be the Prevention?
Vaccination is needed in order to prevent whooping cough. The vaccines are advised to be administered at the age of two months, four months and six months respectively. The 1st booster dose is to be given at 16 to 18 months age and 2nd booster dose is given on 5 year completion of age. An optional booster may be given at 10 year age.

Whooping Cough in Kids - How It Can Be Treated?

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?

Automatic Implantable Cardioverter Defibrillator is an electronic device that is located in the chest of the patient suffering from arrhythmia. Arrhythmia is a condition which causes abnormal rhythm of heartbeat in the patients. It is a life-threatening condition. The device is located in the chest to correct the rhythm of a heartbeat.

AICD device works in two ways:

Firstly, it tries to correct the abnormal heartbeat rhythm and release high- speed heartbeat pace. This is called cardioversion. Patients with AICD generally do not feel the process.

However, if the effect of cardioversion is null then the device will give a mild electric shock to the patient's heart to correct arrhythmia and reset the rhythm.

This second method is called defibrillation. The patient can feel the defibrillation.

The modern-day AICD device is programmed to store the data about the patient s heart rhythm. Doctors use the programmed device which contains your condition and provides medically correct therapy.

Preparation for AICD Implantation

The patient is required to fast six hours before undergoing the surgery. On admission, prescribed medicine is given to the patient and the latest heart condition is measured by an ECG test. If the patient is on blood-thinning medication, then it will be stopped 24 hours before the surgery.

The procedure will be carried out by a cardiologist. The patient will remain under observation in the hospital for at least two days.

Procedure

The entire process of setting up the device in the chest of the patient takes about 2 hours. The patient is sedated, and the area below the collarbone is numbed for the operation. A small incision is made in the chest area. With the help of imaging techniques, cardiologist sets up the device in the chest. The device is then connected to the veins and the heart. After the surgery, the patient is kept under observation. Heart rate, blood pressure, and overall health condition are observed by the doctors to determine successful implantation of Automatic Implantable Cardioverter Defibrillator (AICD). Post Procedure After the successful recovery of the patient, doctors usually discharge the patient with AICD attached. The doctors give complete care instructions of the device along with health. Doctors also guide the patient through the list of activities that one can and cannot perform. AICD is a life-saving device. Hence, proper care and regular check-ups are recommended by the doctors. The regular check-up of the device is also essential since the device runs on a battery. The doctors also train the patient about the workings of the device. They will also explain about the mild shocks of the device one may receive to correct the arrhythmia. Before leaving, make sure the site of the surgery is dry and healing, and you do not have a fever for the past 24 hours.

AICD Implantation - Know Procedure Of It!

The festival of Diwali is greeted with great pomp and splendour and along with the regular festivities, the pollution levels in the air also rise due to the ritual of bursting fire crackers. In an analysis, the rise of harmful pollutants such as sulphur dioxide and nitrogen dioxide seemed to reveal a disturbing outcome.

The rise in pollution during Diwali affects you in the following ways:

The PM (particulate matter which is smaller than 2.5mm) enters your lungs and bloodstream and has several health impacts including chronic respiratory symptoms such as painful breathing and shortness of breath which might cause premature death.
High sulphur dioxide levels in the air during Diwali also lead to inflammation of air passages and causes complications in respiration.
A compound called  strontium  found in the atmosphere multiplies by 120 times during the festival and causes bone damage and blood clotting ailments.
Firecrackers contain heavy metals which are toxic to the human body and the amount of magnesium in the air goes up by 22x, which poses a significant threat to all forms of life.
The noise pollution also rises during the festival and in extreme cases, can permanently damage one s hearing.
However, there are a few measures you can undertake to steer clear of the excessive pollutants present in the air:

Limit the amount of time you spend outdoors even while exercising. This is because the air remains contaminated, days after all the festivities get over and the pollutants take a very long time to dissipate.
Even on the road, drive with the windows of your car rolled up to avoid intake of adulterated air and use a face mask if you are a two-wheeler rider.
Plant a lot of green plants inside your house as they purify the air you are breathing and ensure a supply of fresh oxygen.
Install an air purifier in the room to make sure you breathe in fresh, uncontaminated oxygen when you sleep. The air purifier will also help in lessening your respiratory complications.
Also, in case you notice any respiratory or breathing problem, it is advisable that you consult a pulmonologist, to rule out serious health issues. 

Diwali - How the Rise in Pollution Level Affects Your Health?

Pulmonary hypertension mainly occurs due to narrowing of the arteries of the lungs as a result of which the flow of blood is restricted. In this kind of condition, blood fails to carry oxygen to your heart and thus your heart gets adversely affected. The blood pressure of your body will get increased to a great extent if this situation remains untreated, thus leading to bdreadful consequenses, specifically situation like heart failure, serious pulmonary diseases, blood clots in lungs and congenial heart defects, etc.

There are certain forms of pulmonary hypertension, which are serious in nature and worsen with time, so much so that they are even fatal at times. It also includes forms which are non curable in nature, however, in order to improve the quality of life, symptoms can be reduced with proper treatment. The treatment for pulmonary hypertension is often complex and it takes some time to find the most appropriate treatment and requires extensive follow-up care. Your doctor might also need to change your treatment if it's no longer effective. However, when pulmonary hypertension is caused by another condition, your doctor will treat the underlying cause whenever possible.

Common treatments for pulmonary hypertension:

Medications

1. Blood vessel dilators (vasodilators): vasodilators open narrowed blood vessels. They are one of the most commonly prescribed vasodilators for pulmonary hypertension is epoprostenol (flolan, veletri). The drawback to epoprostenol is that the effect lasts only for few minutes. This drug is continuously injected through an intravenous (iv) catheter via a small pump that you wear in a pack on your belt or shoulder.

2. Ventavis: another form of the drug, iloprost (ventavis), can be inhaled six to nine times a day through a nebulizer, a machine that vaporizes your medication. Because it's inhaled, it goes directly to the lungs.

3. Treprostinil (tyvaso, remodulin, orenitram): it is another form of the drug, which can be given four times a day and can be inhaled or can be taken as an oral medication and can also be administered through injection.

4. Endothelin receptor antagonists: these medications reverse the effect of endothelin, a substance in the walls of blood vessels that causes them to narrow. These drugs may improve your energy level and symptoms. However, these drugs shouldn't be taken if you're pregnant. Also, these drugs can damage your liver and you may need monthly liver monitoring.

6. Sildenafil and tadalafil: sildenafil (revatio, viagra) and tadalafil (cialis, adcirca) are sometimes used to treat pulmonary hypertension. These drugs work by opening the blood vessels in the lungs to allow blood to flow through more easily.

6. High-dose calcium channel blockers: these drugs help relax the muscles in the walls of your blood vessels. They include medications, such as amlodipine (norvasc), diltiazem (cardizem, tiazac, others) and nifedipine (procardia, others). Although calcium channel blockers can be effective, only a small number of people with pulmonary hypertension respond to them.

7. Soluble guanylate cyclase (sgc) stimulator: soluble guanylate cyclase (sgc) stimulators (adempas) interact with nitric oxide and help relax the pulmonary arteries and lower the pressure within the arteries. These medications should not be taken if you're pregnant. They can sometimes cause dizziness or nausea.

8. Anticoagulants: your doctor is likely to prescribe the anticoagulant warfarin (coumadin, jantoven) to help prevent the formation of blood clots within the small pulmonary arteries. Because anticoagulants prevent normal blood coagulation, they increase your risk of bleeding complications. Take warfarin exactly as prescribed, because warfarin can cause severe side effects if taken incorrectly. If you're taking warfarin, your doctor will ask you to have periodic blood tests to check how well the drug is working. Many other drugs, herbal supplements and foods can interact with warfarin, so be sure your doctor knows all of the medications you're taking.

9. Digoxin: digoxin (lanoxin) can help the heart beat stronger and pump more blood. It can help control the heart rate if you experience arrhythmias.

10. Diuretics: commonly known as water pills, these medications help eliminate excess fluid from your body. This reduces the amount of work your heart has to do. They may also be used to limit fluid buildup in your lungs.

11. Oxygen: your doctor might suggest that you sometimes breathe pure oxygen, a treatment known as oxygen therapy, to help treat pulmonary hypertension, especially if you live at a high altitude or have sleep apnea. Some people who have pulmonary hypertension eventually require continuous oxygen therapy.

Surgeries

1. Atrial septostomy: if medications don't control your pulmonary hypertension, this open heart surgery might be an option. In an atrial septostomy, a surgeon will create an opening between the upper left and right chambers of your heart (atria) to relieve the pressure on the right side of your heart.

2. Lung transplantation: in some cases, a lung or heart lung transplant might be an option, especially for younger people who have idiopathic pulmonary arterial hypertension.

Reducing complications

1. The complications need to be reduced by taking proper health care. Healthy diet needs to be taken regularly along with proper medications. Smoking should be stopped and exercising sessions should be attended daily without any fail

2. Overweight or obesity needs to be controlled properly for reducing the complications. Specialized caring strategies need to be maintained for avoiding severe kinds of health complications that are quite annoying.
