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

If you are experiencing difficulty in breathing or rapid breathing, shortness of breath and low blood pressure, you might have been affected with acute respiratory distress syndrome or ARDS. This is a fatal lung condition in which the supply of oxygen to the lungs and into the blood gets prevented. The symptoms of this syndrome develop within two days of the illness. Here are 10 important facts about ARDS you should know about:
Because of the low level of oxygen in the blood, the organs of the body may not function properly. The kidneys and brain require constant oxygen-rich blood supply and there are chances of organ failure due to ARDS.
Commonly, people who get ARDS are already in hospital for some other health problem. People who are not hospitalised may get ARDS because of conditions such as pneumonia.
In ARDS, the tiny blood vessels of the lungs leak more fluid than usual into the air sacs of the lungs. This happens because of infections, injuries or some other condition. The lungs cannot get filled up with air and sufficient oxygen is prevented from getting pumped into the bloodstream.
Several factors also lead to ARDS. These include sepsis, severe bleeding due to any injury on the head or chest, breathing in harmful smoke, or inhaling vomited content of the stomach from the mouth.
People who are prone to ARDS have some condition that may injure their lungs directly or indirectly.
The initial symptoms of ARDS include a feeling of not getting sufficient air in the lungs, low oxygen levels in the blood and rapid breathing. The diagnosis of ARDS depends on your medical history and the results from several tests and physical examinations.
The treatment of ARDS is undertaken by oxygen therapy, medicines and fluids. A patient with ARDS is likely to develop some other health condition while in the hospital, such as lung scarring, blood clots, infections and pneumothorax.
Many people recover from ARDS completely while others keep on facing certain health problems, such as shortness of breath, muscle weakness, depression and fatigue. Problems related to memory and clear thinking are also indicated.
By improving your quality of life, you can recover from ARDS. You need the support and encouragement of your family and friends. You must avoid smoking and keep away from any kind of lung irritant.
The treatment for ARDS has showed progress in the recent years. Hence, more people are recovering from this condition. New treatment procedures are being researched on.


10 Facts About Acute Respiratory Distress Syndrome

Tuberculosis refers to an infectious disease associated with the lungs, which is mostly caused by bacteria. There are two types of tuberculosis, that are pulmonary tuberculosis and extrapulmonary tuberculosis. There are various types under each type of tuberculosis. Here are some the possible treatments for both pulmonary and extrapulmonary tuberculosis.

What is pulmonary tuberculosis?
Pulmonary tuberculosis is a type of disease in which bacteria invade your lungs. It is possible that the bacteria in your lungs could kill you. However, fortunately if you have been taking the right medicines for your bacterial infection you can get cured immediately. The name of the bacteria which causes tuberculosis is known as the Mycobacterium tuberculosis. However, Mycobacterium tuberculosis can attack other parts of the body as well. When this happens, it is known as extrapulmonary tuberculosis.

What is extra-pulmonary tuberculosis?
Extrapulmonary tuberculosis is when tuberculosis affects in parts of the body other than the lungs. There are many parts of the body which tuberculosis can affect, including the lymph nodes, nervous system as well as the bone and joints. Luckily, it is easily curable.

Treatment for pulmonary tuberculosis
Firstly, it is worth noting that latent tuberculosis has no symptoms and there is no way you can pass it to another person either. However, it is still crucial that you take treatment for it. If you do not complete your treatment, then your tuberculosis will progress to a very dangerous form of tuberculosis. This is known as multidrug-resistant tuberculosis. Multidrug-resistant tuberculosis is sometimes abbreviated as MDR TB. There are plenty of medicines which people are recommended to cure tuberculosis. These include:
1. Isoniazid
2. Rifampin
3. Ethambutol
4. Pyrazinamide

Treatment for extrapulmonary tuberculosis
Extrapulmonary tuberculosis has pretty much the same symptoms as pulmonary tuberculosis. This is because extrapulmonary tuberculosis is the exact same disease which occurs to the patient, it is just that it affects a different body part. Therefore, the exact treatment recommended for pulmonary tuberculosis can be used to cure extrapulmonary tubercul

Types Of Tuberculosis: Pulmonary and Extra-Pulmonary and Treatment For Them

Without our lungs, it would be impossible to breathe. People suffering from chronic lung diseases have compromised lung functioning. This leads to shortness of breath, fatigue and weakness. In turn, this can make the person avoid anything that exerts the lungs such as exercise. While this may seem like a good idea, it is actually detrimental. Not exercising can further weaken the lungs and muscles and make this a vicious cycle. This is where physiotherapy can help with lung rehabilitation or pulmonary rehabilitation.

Physiotherapy is a branch of medicine that treats diseases and health conditions with exercise and manual therapy. Physiotherapists may also use radiation, sound waves, electric therapy, prosthesis and assistive devices. The aim here is not to cure the disease but to improve lung functioning and the patient s quality of life. Pulmonary rehabilitation can help in a number of ways.

It reduces breathlessness: As the lung muscles weaken, their ability to pump oxygen and transport it to the other parts of the body reduces. This can make a person feel breathless even with the slightest exertion. Lung rehabilitation works on strengthening the lung muscles to reduce this breathlessness.
It increases muscle strength in the arms and legs: When oxygen does not reach the limbs, they, in turn, get weaker. By strengthening the lungs, lung rehabilitation increases the muscle strength in the patient s arms and legs.
It increases stamina and endurance: Stamina is directly linked to lung functioning. By helping the patient breathe more comfortably, lung rehabilitation increases the patient s stamina and helps him or her endure more physical exercise.
It helps patients understand your condition: Physiotherapy is part exercise and part education. By helping patients get an insight into their condition, physiotherapy helps them come to terms with their limitations and motivates them to work harder towards overcoming them.
It increases self-confidence: Feeling breathless and tired all the time can make people feel frustrated. This is especially so because these things cannot be controlled without help. Physiotherapy teaches patients how to deal with these issues and thus increases their confidence in dealing with their medical issues.
It makes patients more independent: A lack of energy can make people dependent on others. Even simple tasks like getting a bottle of water from the fridge can seem like a tiring task. Physiotherapy improves lung functioning and hence makes the person feel less tired doing everyday tasks. This makes the person more independent and improves their quality of life.

Tuberculosis is a highly infectious and potentially fatal disease which primarily affects the lungs. It is highly contagious and can infect other people via the tiny water droplets released by an infected person while coughing or sneezing. Some strains of this disease have the potential to resist drugs, which are commonly used to cure tuberculosis.

Read more to find all about the different causes, symptoms, preventive measures and the treatment of tuberculosis:

Symptoms: Tuberculosis, also known as TB, can be both latent and active. In latent condition TB is not contagious and it does not harm the infected person. But latent TB can change to an active form so treating it in its latent condition is highly advisable. Active TB can be diagnosed due to the prevalence of certain symptoms such as a cough, which lasts for more than 3 weeks, coughing up of blood, unintentional weight loss, chills, chest pain, loss of appetite and fever. Tuberculosis mainly affects the lungs, but can also affect your kidneys, brain and spinal cord.
Causes: Tuberculosis in general is caused by infection. It spreads from person to person by ultra-small droplets, which an infected person releases while coughing or sneezing. Tuberculosis is highly contagious but it is not very easy to catch TB as the immune system of your body fights it off. Also if a patient of TB is under treatment, the person 's disease is no more contagious.
Risk factors: Potentially everyone can be infected with TB but certain factors increase the chances of infection such as a weakened immune system, living in or travelling to certain areas and substance abuse. TB can also cause complications such as spinal and joint damage, liver or kidney problems and heart disorders.
Treatment: Administering medical drugs is the most convenient way of treating TB. But TB is more persistent than normal bacterial infections and utmost care and caution must be taken to treat it. Completion of treatment is highly essential to fully cure TB. Some of the side effects of TB medication include loss of appetite, nausea or vomiting, dark urine and jaundice.

World Tuberculosis Day - Know More About It!

The term asthma and bronchial asthma are often used interchangeably. Bronchial asthma refers to the chronic inflamation of the airways either due to some internal or environmental allergen. This leads to the narrowing of airways, which makes breathing difficult and blocks air from entering the lungs. Children are most affected by this condition as the immune system is still in the process of maturity and often grows out of it as they age. However, if not treated, this can lead to many complications like respiratory failure and can prove to be fatal. Asthma cases often spike in winter months and in the flowering season. It can also be triggered by second hand or passive smoke, stress, sudden unaccustomed physical exercise, food additives, dust, house mites, perfumes, certain drugs and many other allergens. A family history of asthma, allergic rhinitis, atopic dermatitis and other allergic conditions can also increase a child s risk of suffering from this condition.

Some of the most noticeable symptoms of bronchial asthma include:

1. Wheezing 
2. Shortness of breath 
3. Excessive coughing that worsens at night 
4. Tightness of the chest 
5. Lowered energy levels 
6. Rapid breathing 
7. Tiredness 
8. Indrawing of chest and lower neck

These symptoms often worsen after exercising. Lung function test and Chest X-ray are often used to confirm a diagnosis of bronchial asthma. Once diagnosis is being confirmed, it should be categorized as per severity. Your doctor may prescribe medication in the form of pills and inhalants as per the category of disease. It is important to note that these cannot cure asthma, but can help manage it. Inhalers deliver low doses of steroids directly to the lungs to reduce inflammation and other inhaled medication like Beta 2 agonist will open the airway by relaxing the muscles of airway. Children suffering from asthma must be taught how to use the inhalers and should always have it with them. In the case of school going children, their teachers should also be informed about the condition. Parents should also know how to keep it, use it and clean the device in a proper and hygienic way.

In very small kids those inhalational medication can be given by face mask and spacer, but as the age grows or in case of elder children above 6 years of age, they can directly take the medication from spacer. Those children who are already on inhalers, but still face asthma attack , for them nebuliser is the better choice to manage the emergency. It will make the liquid medicine into mist and enters into the air passage easily and work promptly.

In addition, certain lifestyle changes can also help reduce the frequency of asthmatic attacks. Avoid going outdoors on windy days or days when air pollutant level is high. Reduce the child s exposure to allergens like pet hair, dander and dust by dusting and vacuuming on a weekly basis. Avoid the use of humidifiers inside your house as moist air can promote the infestation of dust mites. Try to keep the child in a room with adequate air and sunlight. Take plenty of green leafy vegetables and fruits, which contain lots of vitamins and minerals. If possible get your child to wear cover his or her nose and mouth while in outdoors.
