Lung Cancer - Symptom, Treatment And Causes

Lung cancer starts from the lungs and spreads to other body parts. In most cases it starts in the airways of the lungs, known as alveoli and bronchioles. There are over 20 types of lung cancer. The cause of most lung cancers is smoking, both from smoking and passive smoking. People who never smoke are also prone to get it and the cause in such cases isn’t known.

The two major types of lung cancer based on the microscopic appearance are:

  • Small-cell lung cancer: It is the major type of lung cancer and affects smokers exclusively.
  • Non small-cell lung cancer: It is a term for lot of different lung cancer types that have similarities. Large-cell carcinoma, squamous-cell carcinoma and adenocarcinoma all come under this category.

Chemotherapy aims at killing cancer cells. Drugs might be administered by a vein, usually in the arm or through the oral route. Multiple drugs are generally given over few months. A surgeon removes the cancer and some part of the adjacent healthy tissue.

Here are the procedures done to obliterate lung cancer:

  • Wedge resection- A small part of the lung that has the tumour with marginal healthy tissue is removed.
  • Segmental resection- A larger part of the lung is removed.
  • Lobectomy- A whole lobe of the lung is removed
  • Pneumonectomy- An entire lung is removed

Radiation therapy employs energy beams obtained from protons and X-rays for killing the cancerous cells. It can be done externally or may be placed within the body close to the affected area through seeds, catheters or needles. Palliative care, a specialty medicine field, involves a doctor’s help to reduce symptoms and signs.

Alternative and complementary lung cancer treatment options are available to reduce symptoms and signs, even though they may not be able to cure cancer:

  • Meditation- It involves focusing on a thing like an image, sound or idea. It helps reduce distress and improves the life quality of cancer patients.
  • Yoga- It includes stretches with meditation and deep breathing. It helps with sleep. An instructor can guide you through the exercises and movements. Don’t do stretches that strain you or feel uncomfortable.
  • Acupuncture- A trained professional puts in tiny needles in specified points in the body during an acupuncture session. It may reduce pain and the side effects of cancer treatment. However, there isn’t any evidence that acupuncture affects the cancer in any way.
Treatable by medical professional Require medical diagnosis Lab test not required Chronic: can last for years or be lifelong Non communicable
Symptoms
It generally doesnt have any symptoms. When the symptoms start appearing , they can be scary like blood in the mucus. Wheezing with chest pain Swollen face and neck Difficulty in swallowing Severe headaches, body pain and fatigue

Lung Cancer
Lungs are two cone shaped spongy organs of respiration are contained within the pleural cavity of the thorax. They are connected with pharynx through trachea larynx. The base rests on the diaphragm. The primary purpose of the lungs is to bring air blood into intimate contact so that oxygen can be added to the blood carbon dioxide can be removed. Adenosarcoma use ally arise from outer areas of the lungs. Cancer may appear as an ulcer in the windpipe, a nodule or small flattened lump blocking the air tubes. It may invade surface of tubes & extend to lymphatics blood vessels. About 40 to 45% of lung cancers are squamous cell cancers. This cancer, even well advanced, produces no out ward symptoms. Cough is the most common symptom it may also triggger shortness of breath wheezing. Cough can be taken as ordinary symptom & this is way treatment is delayed. By the time, lung cancer is found the patient is nearly dead. 80% about of lung cancers are produced by smoking. Sometimes coal tar asbestos products can also produce it. Smoking causes lung cancer in two ways. First of all smoke inhalation damages the normal cleaning process by which the lung protects itself from the injury. Bronchi tube like structure, conduct inhaled air to the lung tissues. Hair like cilia beat in rhythmic fashion to move the mucous membranes continually upwards from the lung, removing any inhaled particles trapped in the sticky mucus. On account of these changes, the lung cannot keep itself clean. A person who has smoked for about 20 years is at the maximum risk of this type of cancer. Smoking includes passive smoking. All of them are harmful to the lungs. Under the microscope examination of sputum. Examination of the airways is done by passing a tube through the mouth or nose into the airways subdivision of each lung. If an obstructing tumor is seen its biopsy is done. Needle biopsy when the cancer cannot be detected by test no. 2 a fine needle is introduced through the chest wall directly in the tumor with the help of x -ray guidance.

How The Rising Pollution Is The Cause Of Cancer?
Are you aware of the link between air pollution and cancer? Air pollution refers to the mixture of several harmful substances, which lead to various serious health hazards on exposure. The primary sources of air pollution are man-made, including fumes from automobiles and the smoke from burning fuels. Desert dust, radon gas, and several other natural sources of air pollution are equally dangerous. Air pollution is classified into outdoor and indoor air pollution. It is highly associated with increased risks of developing cancer. Smoking is considered to be one of the major agents, which pollute the air and increase the chances of cancer to a large extent. Outdoor air pollution Outdoor air pollution is strongly linked with cancer development. As every person is exposed to some form of air pollution, it has a more harmful effect on the whole population across the globe as a general threat. A certain part of outdoor air pollution referred to as PM 2.5, or solid dust particles, are highly responsible for the development of cancer. The chances of cancer increase with the increase in PM 2.5 levels in the air. Indoor air pollution There are several sources of indoor air pollution that are closely associated with an increased risk of cancer. The sources include fuels used for heating homes and for cooking, radon, and tobacco smoke. Second hand smoke is another harmful indoor air pollutant that causes cancer. Second hand smoke Secondhand smoke increases the risk of cancer development, along with the risk of developing other diseases such as stroke and lung disease. A lot of people all over the world get exposed to second hand smoke. A lot of deaths occur due to cancer because of second hand smoke exposure which is common every year, all over the globe. Radon Radon is a natural radioactive gas, which is associated with increased risks of developing lung cancer. It is found at low levels outdoors. It may also build in high concentrations indoors. Although radon exposure does not pose a huge threat for cancer, a lot of radon-associated cancers develop due to exposure to radon, along with tobacco smoke. Benzene This is a flammable liquid having no color and with a sweet odor. It is closely associated with the development of leukemia and cancers affecting other cells of the body. Cigarette smoking and tobacco smoke are major cancer causing elements that are found in the air commonly. Both of these are quite harmful. It is recommended that you not only quit smoking, but also keep away from passive smoking.

Early Warning Signs Of Cancer That We Often Ignore!
Cancer has been regarded as one of the most deadly diseases. It is a non-communicable chronic disorder, caused by uncontrolled growth of cells in the human body. Every year over 7 million people succumb to this disease globally and over 12 million people are diagnosed with cancer. Indian Council of Medical Research (ICMR), estimated that India will observe over 8 lakh deaths and over 17 lakh new cancer cases annually by the year 2020. The survival expectancy of a cancer patient depends upon the stage of diagnosis. There are some forms of cancer which show noticeable symptoms only during the final stage, while there are others with subtle symptoms which if paid attention to can help save a number of lives. Some common signs of cancer: Unexplained weight loss: This is one of the earliest noticeable symptoms of cancer and is particularly common in patients of lung and breast cancer. Weight loss has been observed in over 40% of cancer patients at the time of diagnosis. Losing over 10% of body weight in a span of 6 months or less could be a cause of concern. Wheezing: This is associated with lung cancer, which is also the most common form of cancer. When the airway in the lungs is pressed or narrowed by a tumor, it creates a wheezing sound while breathing. Frequent infections: Frequent infections and fever may indicate that something is not right with the internal organs of the body. This could be because of cancerous conditions such as leukemia or lymphoma. Loss of appetite: Cancer impacts the metabolic process of the body, hence often leads to a loss of appetite. This is particularly a symptom of colon, stomach, ovaries and pancreatic cancer. Blood in stool/urine: Traces of blood while passing stool or urine could be a symptom of cancer. Though, this could be attributed to many other infections and conditions as well. Chronic cough: Flu and cough along with symptoms like chest pain, hoarseness, weight loss and fatigue could be because of lung cancer. Night sweats: Though night sweat could be attributed to many more reasons, it is also one of the many early warning signs of cancer. Cancer symptoms specific to men: Blood in semen Pain during ejaculation Lump in testicles Cancer symptoms specific to women: Lump in the breast Lump under arm Bleeding after menopause or in between periods Early detection is the key to success in your fight against cancer. So, if you witness any of the above symptoms get yourself diagnosed at the earliest. In case you have a concern or query you can always consult an expert & get answers to your questions!

Symptoms of Lung Cancer In Hindi - फेफड़ों के कैंसर के लक्षण
फेफड़ों का कैंसर का कारण फेफड़ों की कोशिकाओं का अनियंत्रित रूप से बढ़ना है. इन कोशिकाओं की संख्या धीरे-धीरे बढ़कर एक ट्यूमर का रूप ले लेती है. कैंसर के ज्यदातर खतरनाक मामले जिनमें मौत होने की संभावना होती है उन सभी में मृत्यु के लिए मृत्यु के लिए फेफड़े का कैंसर ज़िम्मेदार है. फेफड़ों के कैंसर को मुख्य रूप से दो भागो में बाँटा गया है स्मॉल सेल लंग कैंसर (एससीएलसी) और नॉन-स्माल सेल लंग कैंसर (एनएससीएलसी). एससीएलसी, नॉन-स्माल सेल लंग कैंसर की तुलना में ज़्यादा आक्रामक होता है. एनएससीएलसी फेफड़ों के कैंसर का अधिक सामान्य रूप है - 80-85% लंग कैंसर के मामलों एनएससीएलसी के होते हैं. फेफड़ों में होने वाले कैंसर का सबसे सामान्य लक्षण खाँसी है, जो धीरे धीरे गंभीर रूप ले तेती है. इसके ठीक होने में लम्बा समय भी लग सकता है. इसके अन्य लक्षणों में निमोनिया या ब्रांगकाइटिस है जो बार-बार होता रहता है, वज़न कम होना, भूख में कमी होना, थकान, सांस लेने में तकलीफ, आवाज़ का बदलना भी इसके अन्य लक्षणों में शामिल हैं. आइए फेफड़ों के कैंसर की गंभीरता को देखते हुए इसके लक्षणों को एक-एक करके समझने की कोशिश करें. 1. पेरानियोप्लास्टिक लक्षण जाहिर है प्रत्येक बीमारी अपने साथ कुछ लक्षणों को भी लाती है जिसके आधार पर हम उसकी पहचान करते हैं. फेफड़े के कैंसर अक्सर लक्षणों के साथ होते हैं, जो ट्यूमर कोशिकाओं द्वारा हार्मोन जैसे पदार्थों के उत्पन्न होने से विकसित होते हैं. ये पेरानियोप्लास्टिक लक्षण सबसे ज़्यादा एससीएलसी में पाए जाते हैं, लेकिन किसी ट्यूमर के प्रकार के साथ भी देखे जा सकते हैं. 2. कैंसर से संबंधित लक्षण फेफड़े और उसके आसपास के ऊतकों पर होने वाले कैंसर के आक्रमण से श्वसन प्रक्रिया में समस्या उत्पन्न हो सकती है. इसमें खाँसी, सांस की तकलीफ, ज़ोर ज़ोर से सांस लेना, सीने में दर्द और खाँसी के साथ रक्त निकलना (हेमोप्टेसिस) जैसे लक्षण हो सकते हैं. यदि कैंसर तंत्रिकाओं पर हमला करता है, तो कंधे में भयंकर दर्द होता है. यह दर्द कंधे से लेकर बांह को प्रभावित करता है या इसके कारण स्वरतंत्री भी पैरालाइज हो सकती हैं. कैंसर से प्रभावित भोजन नली द्वारा निगलने में कठिनाई हो सकती है. 3. गैरविशिष्ट लक्षण फेफड़ों के कैंसर के कुछ लक्षण ऐसे भी होते हैं जो गैरविशिष्ट लक्षणों के अन्तर्गत आते हैं. इन्हें कई प्रकार के कैंसरों के रूप में देखा जाता है, जिनमें लंग कैंसर भी शामिल है. इन लक्षणों में हमें वजन घटना, कमजोरी और थकान आदि दिखाई पड़ सकते हैं. इसके अलावा कुछ मनोवैज्ञानिक लक्षण, जैसे अवसाद और मनोदशा में होने वाले परिवर्तन भी आम हैं. 4. मेटास्टेसिस से सम्बन्धित लक्षण मेटास्टेसिस का मतलब है कि कैंसर जिस अंग से शुरू हुआ था, उससे बढ़कर अन्य अंगों तक पहुँच चुका है. फेफड़ों का कैंसर हड्डियों में फैलकर उनके जोड़ों में असहनीय दर्द पैदा कर सकता है. मस्तिष्क में कैंसर के फैलने पर कई न्यूरोलॉजिक लक्षण भी उत्पन्न हो सकते हैं. इनमें धुंधली दृष्टि, सिर दर्द, दौरे या स्ट्रोक के लक्षण जैसे कि शरीर के कुछ हिस्सों में होने वाली सनसनी का कम या खत्म हो जाना शामिल हैं. 5. कोई लक्षण न होना कई बार ऐसा भी हो सकता है कि इसके लक्षण हमें प्रत्यक्ष रूप से नजर न आएं. या बेहद कमजोर नजर आएं. ऐसे में लक्षणों का सामने न आना खतरनाक हो सकता है. इसलिए आपको समय-समय पर जांच कराते रहना होगा. फेफड़ों के कैंसर से पीड़ित को नियमित रूप से छाती के एक्स-रे या सीटी स्कैन द्वारा एक छोटे घाव से कराते रहना चाहिए. द्विआयामी एक्स- रे या सीटी स्कैन द्वारा परीक्षण करने पर ये गोल ट्यूमर एक सिक्के की तरह लगता है. जिन रोगियों में पहली बार लंग काकनेर का निदान कॉइन लेशन से किया जाता है, उनमें लंग कैंसर पाए जाने के समय अक्सर कोई लक्षण दिखाई नहीं देते.

Know About Common Lungs Diseases!
Lung diseases are some of the most common diseases suffered by human beings throughout the world. Smoking and infections are responsible for most lung diseases. The lungs perform one of the most important functions of the body. It is also one of the most active organs in the human body and hence lung problems can arise due to problems in any other part of the body. Some of the most common and infectious lung diseases are discussed below... 1. Asthma Asthma is a common long term disease which is characterized by reversible airflow obstruction and bronchospasm. The symptoms of asthma include coughing, shortness of breath and tightness of chest. These symptoms may occur frequently during a day and depending on the person, it may become worse during night or during a certain exercise. 2. Pneumonia Pneumonia is another common lung problem which is suffered due to inflammation in the microscopic air sacs in the lungs known as alveoli. Symptoms of pneumonia include dry cough, chest pain, breathing problem and fever. Pneumonia is caused most commonly by viruses or bacteria. It is also caused by certain medications and conditions which are popularly known as autoimmune diseases. There are a number of vaccines available to prevent certain types of pneumonia. Other methods include hand washing and refraining from smoking. 3. Tuberculosis Tuberculosis is a very infectious disease which is caused by the bacteria Mycobacterium tuberculosis. Although tuberculosis generally affects the lungs, but it has been known to affect other parts of the body as well. Symptoms of tuberculosis include cough containing sputum with blood, night sweats, fever and weight loss. Air is an active medium for spreading tuberculosis. This happens when people who already have tuberculosis sneeze, cough or speak. Infection occurs more in those who have HIV/AIDS or those who smoke. Prevention of tuberculosis includes staying away and keeping those who are at high risk, early detection and treatment and vaccination. 4. Mesothelioma Mesothelioma is a type of cancer which affects the lungs. It affects the lining of the lungs and chest wall. Symptoms of mesothelioma include shortness of breath, swollen abdomen, cough, chest pain, weight loss and general lethargy. Mesothelioma is caused mainly due to exposure to asbestos. Those people who mine asbestos, produce products from asbestos, work with asbestos products are at high risk. Mesothelioma also results from genetical problems and due to infection caused by the simian virus 40. 5. Pulmonary Embolism This is a disease caused due to blockage of an artery in the lungs by a substance which has travelled from another part of the body by the bloodstream. Symptoms of this disease include chest pain, breath shortness and coughing up of blood. There may also be signs of blood clot in the legs.

Hi... Ideally the answer is yes it can be.. but is not the only disease having the same symptoms... so instead of directly reaching on to such grave conclusion you should get properly examined... and get diagnosed... even cancer is curable now a days if diagnosed and treated in time...
