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

COPD, also known as Chronic Obstructive Pulmonary Disease is a chronic medical condition that triggers extensive damage to the lungs, interfering with its functioning. In COPD, the lungs and the air sacs or the alveoli undergo severe inflammation that gives rise to a host of complications including wheezing, shortness of breath and other related breathing troubles. While an early medical assistance is instrumental in proper management and treatment of COPD, in most cases, the associated symptoms and discomfort appear at a later stage (when the lungs have already undergone damage and inflammation). Thus, a proper awareness about COPD is necessary. In this article, we will discuss some important points related to COPD to help people understand the condition better.

While there can be a plethora of triggers, two of the medical conditions that elevate the incidence of COPD are Chronic Bronchitis and Emphysema. The bronchial tubules functions as a carrier transporting the air (oxygenated and deoxygenated) from the lungs to the different body parts and vice versa. 

In case of Chronic Bronchitis, the lining of these tubules undergo severe inflammation. 
In the case of Emphysema, the inner walls of the alveoli may rupture resulting in deleterious consequences including breathlessness.
For long people were of the opinion that COPD only affects people who smoke. However, various surveys suggest that COPD does affect non-smokers as well. While smoking does make a person more susceptible to the condition (COPD as well as Chronic Bronchitis and Emphysema), other factors such as chronic and severe neonatal lung ailments or prolonged exposure to the harmful gases and lung irritants can also act as triggers.

Though the incidences of COPD are relatively higher in people above 45 years, the young adults or the middle-aged can also be affected. Also, COPD is not limited to males and can affect females as well. Some of the symptoms associated with COPD include chest tightness, wheezing, breathlessness, chronic cough (often with mucus). These symptoms are quite similar to those of Asthma with people often confusing between the conditions. Thus, a proper diagnosis is vital. Spirometry is a lung test used in the diagnosis of COPD. This test evaluates the functioning of the lungs by measuring the amount of air inhaled and exhaled.

When we talk about the treatment or management of COPD, quitting smoking does improve the condition. For people with breathing troubles and chronic cough, the Bronchodilators (can be long-acting or short-acting Bronchodilators depending on the extent of the discomfort) comes as a great relief. The use of corticosteroids (inhaled) can go a long way to alleviate the inflammation of the airways.

In extreme cases with reduced oxygen reaching the blood, a person may need Oxygen Therapy to improve the condition. Of late the Pulmonary rehabilitation program have been benefiting people in dealing with COPD better. The program involves an amalgamation of counselling sessions to educate the people about the diet and nutrition, precautions to be followed along with some healthy lifestyle changes.

COPD - Things You Must Always Remember!

Doctors believe that tonsils and adenoids have a hand in helping the body fight infections. A common problem children face is enlargement of these organs.

Even though most cases of adenoid and tonsil enlargement subside naturally after a few days, in some instances of the disorder, severe symptoms may force you to seek treatment for your child. Here is a look at some complications from an enlarged adenoid and tonsils.

Complications:

  Hearing loss and chronic infection in the ear is a common complication. This occurs when the enlarged lymph tissue blocks fluid transfer in the ear.
  Sinus infections that recur over time
  Sleep apnoea is a common side effect of adenoid and tonsil disorders. This leads to difficulty in breathing while your child sleeps.
  Weight loss is an indirect consequence of enlargement in these lymph tissues. Your child may not be able to eat properly due to the pain experience while swallowing

In case of severe complications, doctors will recommend getting the adenoid and tonsils removed from your child s body. Coblation is the best option in such a case.

What is coblation surgery?

Coblation stands for controlled ablation. It is a minimally invasive surgical procedure where an electrical handpiece is used to  burn  the affected tissue in the throat of children. Extremely low temperatures rectify the problem by  burning  the affected tissue. When the coblation method is used to remove both the tonsil and the adenoid lymph tissues, the procedure is known as Coblation Adenotonsillectomy.

The coblation method has replaced the older method where metallic surgery instruments were used for the removal of these tissues. Such crude methods often resulted in post-operative complications, especially in children.

Here are some benefits of Coblation Adenotonsillectomy:

  Less bleeding during the surgical procedure, limiting dangers to the child s health
  Less pain and discomfort post the surgery for the child, which leads to faster recovery
  Decreased risk of haemorrhage post-surgery

Consult an ENT specialist to know more about Coblation Adenotonsillectomy. They will be able to clarify any doubts you have regarding your child s safety during the procedure as well.

World TB Day Special - How to Prevent Tuberculosis

Myth: COPD is an incurable chronic lung disease mainly affecting the aged people (above 60 years).
Fact: There is no denying the fact that COPD is indeed a chronic disorder that severely affects the lungs and its functioning. However, with timely diagnosis and treatment, the condition and the deleterious consequences can be managed and controlled significantly. Since COPD triggers breathing problems (the airflow from the lungs gets obstructed), the use of bronchodilators, oxygen therapy or corticosteroids can be highly beneficial. Though COPD is rare among young adults, the condition can affect people in their late 30's or early 40's as well.

Myth: COPD only affects people who smoke.
Fact: Smoking is one of the triggers for COPD, but the condition can also affect people who have never smoked in their lifetime. Factors such as neonatal chronic lung disease or prolonged exposure to substances that cause lung irritation and damage (toxic industrial fumes and chemicals) can play a pivotal role in triggering COPD. COPD can also be a genetic predisposition.

Myth: People with COPD should avoid exercise and physical activities.



Fact: Mild to moderate exercise (especially breathing exercise) are indeed helpful and go a long way in the effective management of COPD. Exercising regularly (for 20-30 minutes or as the doctor recommended) help to lower the blood pressure and improve the circulation that provides fruitful results for people with breathing problems. However, doctors do advise people with shortness of breath to avoid strenuous exercise.

Myth: COPD only affects the lungs.
Fact: With time and left unmanaged and untreated, COPD acts as a catalyst making a person more susceptible to heart ailments. In some cases, the condition can also trigger depression and anxiety.

Myth: In the case of COPD, giving up on smoking will not produce any positive results.
Fact: Giving up on smoking may not help to reverse the damage that has already been caused by COPD. However, quitting smoking along with proper medications and lifestyle changes does help to control the condition better. In some instances, there were also significant improvements in the associated symptoms (such as shortness of breath, fatigue, wheezing, a chronic cough).

Myth: COPD is another name for Asthma.
Fact: Many people confuse COPD with Asthma. Though some symptoms may appear identical (such as wheezing, shortness of breath), the conditions are different and so are their treatments. In case you have a concern or query you can always consult an expert & get answers to your questions.
