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!

Cancer is the abnormal, uncontrolled growth of cells in a particular body part. With continued growth, pieces of this tissue travel through the blood to different body parts and continue to grow in the new area. This is known as metastases. Breast cancer is one of the most common forms of cancer and affects about 1 in 8 women in the USA. Read on to know more details of breast cancer   breast anatomy, causes, symptoms, risk factors, detection, prevention, and of course treatment.

Anatomy: The main function of the breast is lactation through its milk-producing tissue that are connected to the nipple by narrow ducts. In addition, there is surrounding connective tissue, fibrous material, fat, nerves, blood vessels and lymphatic channels which complete the structure. This is essential to know as most breast cancers develop as small calcifications (hardened particles) in the ducts or as small lumps in the breast tissue which then continues to grow into cancer. The spread can happen through lymphatic or blood flow to other organs.

Warning signs/symptoms: The following are some symptoms that need to be watched out for if you have a predisposition to breast cancer.

    A lump in either of the breasts or armpits
    Change in size, shape, or contour of either breast
    Redness of your breast or nipple
    Discharge of clear or bloody fluid
    Thickening of breast tissue or skin that lasts through a period
    Altered look or feel of the skin on the breast or the nipple (dimpled, inflamed, scaly, or puckered)
    One area on the breast that looks very different from the other areas
    Hardened area under the breast skin

Either one or a combination of these should be an indication to get a detailed checkup done. Early diagnosis results in controlling the disease with minimal treatment and reduced complications.

Causes and risk factors: The exact cause for breast cancer is yet to be pinned down. However, risk factors are clearly identified, and women with risk factors need to watch out for warning signs.

    Family history: Of all the risk factors, the family history is the most important. Breast cancer runs in families, and if there is a first-degree relative with the breast cancer, the chances of developing it are almost double. Two genes BRCA1 and BRCA2 are the carriers of the disease, and this testing can be done in women to identify if they are at risk.
    Family history of other cancers: Even if there is no breast cancer, if there are other cancers that run in the family, watch out.
    Age: Women over 50 are at higher risk of developing breast cancer.
    Race: Caucasian and Jewish women are at higher risk of breast cancer than African-American women.
    Hormones: Greater exposure to the female hormone estrogen increases the chances of developing breast cancer. Women who use birth control pills for contraception and hormone replacement after menopause are at a higher risk of developing breast cancer.
    Gynecologic milestones: Women who have abnormal menstrual milestones need to watch out. These include those who attain menarche before 12 years of age, get pregnant after 30, attain menopause after 55, and have menstrual cycles shorter than 26 days or longer than 29 days.
    Obesity and alcohol abuse are also likely to increase a woman s chances of developing breast cancer.

Stages: Starting from stage 0, higher stages indicate advanced disease.

    Stage 0: The growth which has begun in the milk-producing tissue or the ducts has remained there (in situ) and not spread to any other area, including the rest of the breast.
    Stage I: The tissue slowly becomes invasive and has begun to affect the surrounding healthy tissue. It could have spread to the fatty breast tissue and some breast tissue may be found in the nearby lymph nodes.
    Stage II: The cancer at this stage grows considerably or spreads to other parts. There are chances that cancer may grow and also spread.
    Stage III: It may have spread to the bones or other organs but small amounts are present in up to 9 to 10 of the lymph nodes in the armpits and collar bones which makes it is difficult to fight.
    Stage IV: The cancer is widespread to far-flung areas like the liver, lungs, bones, and even the brain.

Screening: This is one of the most effective ways to identify the disease in its early stages. This will help in controlling cancer from spreading with minimal treatment.

    Self-examination: A thorough self-examination to look for changes in terms of shape, size, colour, contour, and firmness should be learned by all women. Watch for any discharge, sores, rashes, or swelling in the breasts, surrounding skin, and nipple. Examine them while standing and when lying down.
    In most women, annual screening mammograms are advised after the age of 40. However, in women who have a strong family history or genetic makeup, it is advisable to have screening mammograms starting at age 20 every 3 years and then annually from the age of 40.
    Women in high-risk categories should have screening mammograms every year and typically start at an earlier age.
    Ultrasound screening can also be given in addition to mammograms.
    Breast MRI is another way to screen for breast cancer if the risk is greater.

Breast Cancer Prevention: Now that there is so much awareness about causes and risk factors, there are definitely ways to prevent or delay the onset of the disease.

    Exercise and a healthy diet with reduced amount of alcohol are definitely effective in minimising the chances of developing cancer.
    Tamoxifen is used in women who are at high risk for breast cancer.
    Evista (raloxifene) which is used to treat osteoporosis after menopause. It is also widely used in preventing breast cancer.
    In high-risk women, breasts are surgically removed to prevent the development of cancer (preventive mastectomy).

Treatment: As with all cancers, treatment would depend on the stage at which it is identified and include a combination of chemotherapy, radiation, and surgery. As noted earlier, if you are at risk, look out for warning signs as early diagnosis is the key to maximum recovery.

Breast Cancer - Know More to Say 'No' More!

Cancer today is not as rare as it once was. Today, cancer affects the young and old alike. One of the reasons for this is the pollution in particular air and water pollution that we are exposed to on daily basis.
The air we breathe in today is a mixture of smoke, particulate matter and noxious gases that causes great harm to our bodies. Amongst these, particulate matter that is smaller than 2.5 millionths of a metre is the worst.

These particle matters are emitted into the air from car exhausts, industrial exhausts, coal fires, wood stoves etc. While the body s natural defences help keep larger particle matter out of the system by sneezing or coughing it out, smaller particle matter enters the body easily. These then get trapped in the lungs and enter the bloodstream. Particle matter has in particular been linked to increasing number of lung cancer cases. Apart from lung cancer, coal tar particle matter has been linked to bladder cancer, soot to oesophageal cancer and benzene and other pesticides to leukaemia.

Radon is another source of air pollution that is emitted from the ground. In some cases, radon can also be emitted through the water. As this gas decays, it releases tiny particles that when inhaled bombard the lung cells with radiation that can cause radiation. Smoking can worsen this effect and increase a person s risk of suffering from lung cancer. Both first-hand and second-hand smoking have also been linked to breast cancer. Apart from trying to reduce emissions to lower air pollution, it is also important to clean filets of air conditions, etc. regularly to lower indoor air pollution. Preventing the smoking of tobacco in public spaces can also help improve air quality.

All pollutants emitted by us eventually find their way into the water we drink. Even if you are not drinking contaminated water, merely, showering or swimming in contaminated water can make your body more vulnerable to the carcinogens in it. Common water pollutants include arsenic, hazardous waste, animal waste, radon, chemicals and asbestos. Drinking water with concentrated amounts of arsenic has been linked to cancer of the lungs, liver, kidney and bladder while the chlorine used to treat drinking water increases the risk of bladder and rectal cancer.

To reduce the risks of cancer caused by polluted water, it is essential to reduce disinfectant by products by keeping water treatment facilities updated and promote green chemistry and alternative assessments to reduce pollution as a whole.

Pollution - How It Has Increased the Risk Of Cancer?

Irrfan Khan's saddening revelation about his health and diagnosis of Neuroendocrine tumour (NET) has undoubtedly created a rage amongst his fans, which is now being followed by good wishes for speedy recovery from his supporters all across social media.  

The actor shared in an emotional Twitter post that he s been diagnosed with NET, a rare tumour that develops from cells of the neuroendocrine system and grows predominantly in the digestive or respiratory tract - lungs, appendix, small intestine, rectum, and pancreas - it can occur in any part of the body.

Here is more on Irrfan s disease:

What is NET?

A neuroendocrine tumor is characterized by a rapid and abnormal growth that happens in the nerve cells which produce hormones. Hormones control how different organs in the body work.

It is a condition wherein, endocrine cells, the hormone-producing cells of the body, develop a tumor in any part of the body - while it can can grow in lungs or the thymus, or more rarely, in the ovaries, kidneys, or testicles - the most common is lung, intestines, and pancreas.

What causes NET?

A neuroendocrine tumour is quite a rare disease, occurs in less than one per million cases. The exact cause is not known.

The Symptoms-

It can cause a myriad of symptoms, depending on where in the body the NET is.

If it is in your digestive system, it can cause pain or discomfort in the abdomen area that comes and goes. You may feel sick, nauseated, vomited, or there may be a change in how often you pass stools.
If the NET is in the lung, it can cause shortness of breath, chest infections, or you can even have a cough up blood.
Weight loss and loss of appetite may also be some common signs of a neuroendocrine tumour.
Some NETs may overproduce a hormone-like substance called serotonin. This causes a group of symptoms called carcinoid syndrome. Symptoms include wheezing (like asthma), flushing of the skin and diarrhoea.
Who can be affected with NET?

These tumours, depending on the type, are more common in certain age or sex. And few have very strong family history too.
People who have a rare condition called multiple endocrine neoplasia 1 have an increased risk of developing a NET.
Did You Know?

Apple founder  Steve Jobs  died from the same disease in 2011. The tumour affected his pancreas.

Know The Different Types of NET:

Based on the organ that is affected, NET can vary a lot. When the chromaffin cells that produce adrenaline are affected, it is called Pheochromocytoma, and it is related to the stress levels of the body.

When a cell is formed abnormally under the skin and the hair follicles, it is called Merkel cell cancer. This is also called neuroendocrine carcinoma of the skin and the condition can occur anywhere in the body. The commonly occurring places include lungs, gastrointestinal tract, and brain.

The status of the tumour, cancerous (malignant) or noncancerous (benign), decides the survival rate. Often slow-growing and noncancerous, they can invade surrounding parts of the body and at times, turn cancerous and spread across the body. However, you can still choose to live a good quality life with strict modifications in diet and lifestyle. The changes are made after taking into consideration the symptoms of the tumor. The organ where the tumor is formed also matters.

How Is It Treated?

Treatment depends on the location of the tumour, its type, how severe it is and whether it has spread to other parts of the body. Usually, the first treatment choice is surgery to remove the tumour. And, if the NET cannot be removed, your will prescribed with a treatment that will not only relieve the symptoms but will also improve the quality of your life.

How can a NET be prevented?

The first thing you need to do for the prevention of NET is to curb stress. Stress affects the entire body severely.

Lifestyle modifications:

A healthy lifestyle is what you need to stick to if you want to manage its symptoms during the treatment cycle. Your doctor will prescribe you to do exercises at least 4 days a week for a minimum of 30 minutes. You can also try a walk instead of strenuous exercises.

People with carcinoid syndrome may be advised to avoid food or activities that may trigger flushing, such as eating spicy food or drinking alcohol.

Indulge yourself in therapies that help in gaining more positive energy. If you are already affected by NET, eliminate all the sources of stress and get a good night's sleep every day. Join the support groups that make you grow strong and happy. After all, the mind is devised to do miracles when it is full of life and positive thoughts.

Is Irrfan Khan's tumour curable?

Dr Saumitra Rawat, HOD, Surgical Gastroenterology & Liver Transplant, Sri Ganga Ram Hospital, said, "NeuroEndocrine Tumour is an abnormal growth of Neuroendo cells which are present in bodies. When there is an abnormal growth, then it forms a tumor - Normally seen in intestine, pancreas, lung, thyroid and other parts of the body".

On commenting on Khan's case, he said, "It depends on the location of tumour, its size, and what is its mitotic index".

"Depending on where the tumour is localized, you can take it out surgically and the chances of cure are very high", Dr Rawat explained.

Actor Irrfan, who has been diagnosed with the disease is one of the most versatile actors in India, has also made a name for himself in the west, where he has been an important part of critically-acclaimed films such as  The Namesake ,  Jurassic World , and  Life of Pi . At home, the actor has delivered remarkable performances in films such as  Haasil ,  Paan Singh Tomar ,  Maqbool ,  Lunch Box ,  Piku , and the most recent  Hindi Medium .

Irrfan Khan is not just a disarmingly natural actor, but also an endearing human being -- honest and humble to the core. It s time to stand together and pray for him a speedy recovery!

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! 

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.
