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 - Symptoms At Early & Later Stages!
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 this disease. 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.

Lung Cancer and Outdoor Air Pollution - Understanding The Risk!
Lung cancer is the cancer killer of both men and women in the U.S. When you think of risk factors for lung cancer, what comes to mind? Most of us think about the risk associated with smoking cigarettes, but did you know that air pollution can also cause lung cancer? Overwhelming evidence shows that particle pollution in the outdoor air we breathe like that coming from vehicle exhaust, coal-fired power plants and other industrial sources can cause lung cancer. Particle pollution increases the risk of dying early, heart disease and asthma attacks, and it can also interfere with the growth and function of the lungs. What is Particle Pollution? Particle pollution is a mix of tiny solid and liquid particles in the air and can be made up of a number of components, such as acids, organic chemicals, metals, soil and dust particles. It can be emitted directly from wood stoves, forest fires, vehicles and other sources, and it can also form from other types of pollution that come from sources like power plants. Why does particle pollution harm our bodies? While breathing in larger sizes of particle pollution can be harmful to our health, smaller particles are more dangerous. Bigger particles can irritate your eyes, nose and throat, but our natural defenses help us to cough or sneeze them out of our bodies. Unfortunately, those defenses don't keep out smaller particles, which get trapped deep in the lungs and can even get into the bloodstream, causing damage to our health. Who is most at risk? As for who is at risk for health problems from breathing in particle pollution. Those who live where particle pollution levels are high is at risk. Some people face higher risk, including children, the elderly, people with lung and heart disease and diabetes, people with low incomes, and people who work or exercise outdoors. How do we protect ourselves from particle pollution? Check the air quality index forecast for the day and limit your activity if pollution levels are high. Avoid exercising along heavily traveled highways regardless of the overall forecast. As individuals, we can play our part in reducing air pollution levels by trying to avoid creating more of it. Choosing active travel options where possible, like walking and cycling, can help reduce pollution levels from transport and is also a great way to be more active, which is linked to a reduced risk of cancer and other diseases.

Lung Cancer - How Radiotherapy Treatment Can Help?
Radiotherapy is a kind of treatment that kills the cancer cells by using high-energy beams. Specialists use radiotherapy to treat a wide range of lung cancer. For early stage lung cancer, the radiotherapy may get rid of the cancer totally. For the small cell lung cancer you may have radiotherapy only. Then again you may have it with another treatment, for example, chemotherapy or surgery. For small cell lung cancer, radiotherapy is used with or after chemotherapy. Chemotherapy makes the tumor in the lung shrink. You may have radiotherapy to your cerebrum, which tackles any cancer cells that may have spread to the brain. This is called prophylactic cranial illumination (PCI). In case of advanced lung cancer, the treatment contracts the tumor and controls it for a while. It additionally decreases symptoms like shortness of breath. The types of radiotherapy used for the lungs include: Outer radiotherapy This kind of radiotherapy comes from a machine and is administered to the body through an external source. It depends on the kind of cancer and the progression of the same. You may have three radiotherapy sittings every day for around 12 days. This sort of radiotherapy is known as CHART ceaseless hyperfractionated quickened radiotherapy. A few people with small cell lung cancer may have treatment twice a day. If you are getting radiotherapy to control the side effects of lung cancer, you may have a single treatment or day by day medications for up to 3 weeks. Inner radiotherapy This is called brachytherapy or endobronchial treatment. This will be administered during a bronchoscopy. The radiation is given through a thin tube that the specialist puts inside your aviation route for a few of minutes. Specialists use this sort of treatment to shrink a tumor that is blocking or pushing your breathing track and making breathing troublesome for you. These are some of the procedures that take place while you are having lung cancer radiotherapy: 1. Radiotherapy machines are enormous. The machines are fixed in one position or are sometimes ready to go around your body to give treatment from various angles. 2. Prior to your first treatment, your radiographers will clarify what you will hear and see. The treatment rooms normally have docks for you to connect to music players. So you can listen to your own choice of music. 3. You cannot feel radiotherapy when you really have the treatment. It takes anything from one second to a few minutes. It is essential to lie similarly situated every time, so the radiographers may take a short time to get you prepared. 4. Once you are in the right position, the staff will allow you to sit in the space for a couple of minutes. They watch you constantly on a closed circuit TV screen. They may request that you hold your breath or take shallow breaths during the treatment.

Thoracic Ultrasound - What You Can Expect After Undergoing It?
When your doctor suspects of the presence of extra fluid in your lungs, you might be advised for a thoracic ultrasound. What is a thoracic ultrasound and why do you need it? With a thoracic ultrasound, your doctor will be able to look at everything in the thoracic cavity and can know if your lungs, heart, and other structures in the chest are working fine. The pulmonologists can efficiently determine the lung condition even in critically ill patients using a non-invasive ultrasound technique. And, since the method is based on sound, there is no risk of exposure to potentially harmful ionizing radiation or nephron-toxic contrast dye in this case. Hence, a thoracic ultrasound has become the most preferred technique for conducting a preliminary examination or to further check and confirm a finding noted using other imaging techniques for thoracic diseases. Reasons to have a chest ultrasound The doctor usually refer an ultrasound when he or she can feel that there is some extra amount of fluid in your chest. The ultrasound can tell the physician the reason behind the deposition of excess liquid. The ultrasound would help detect the type of fluid that is present in the chest, whether it is exudate that is caused due to inflammation, an infection, or lung cancer, or whether it is transudate that is a leakage from the lymph nodes or the blood vessel. It determines the movement of the diaphragm. Chest ultrasound can be done in conjunction with other examinations like CT scan, MRI to evaluate the condition of the chest. It has to be noted that, in certain circumstances such as severe obesity and barium in your esophagus, the procedure can give an inaccurate result. Hence, it is always advisable to talk with the health care provider and share your complete medical history before undergoing this procedure to prevent such occurrences. After a Thoracic Ultrasound After the results of the ultrasound are received, the doctor can detect what the condition of your chest is at the moment. Your doctor will also confirm if the lungs have collapsed or if there is water in the lungs, or excess fluid has deposited into the lungs. Ultrasound can also reveal if you have pneumonia. A diagnosis like this does not take a long duration, and thus the ultrasound plays a significant role in expediting the treatment process. There are no hard and fast regulations to follow after the ultrasound. The physician may recommend few instructions depending on your situation. In typical cases, there is no special preparation like fasting is required and you need not be sedated during the ultrasound as well. A safe and painless method to detect the condition of the chest and the respiratory organs and the blood flow through the organs in your chest, a thoracic ultrasound is a preferred procedure that can help your doctor to diagnose your condition and decide upon the treatment method.

CyberKnife Therapy of 24 Multiple Brain Metastases From Lung Cancer!
Brain metastases from systemic cancer are the most common type of intracranial neoplasm in adults, being almost 10 times more common than primary malignant brain tumors, which cause a significant burden on the management of patients with advanced cancer (1). The lungs represent one of the most frequent sources of metastases to the brain, with a probability of (36 64%) (3). Symptoms suffered by the patients include headaches, epilepsy, focal weakness, numbness or changes in mental status. The prognosis of patients with brain metastases is not optimistic and the median survival time is 1 2 months if left untreated. The 1-year survival rate has been recorded as 10.4% (4,5). The treatment of metastatic brain tumors is complex; not only due to being able to provide local control and improve neurological function, but also due to factors such as age, performance and systemic disease status and the size, volume, location and number of metastases at presentation CyberKnife is a robotic radiosurgery system with a linear particle accelerator (linac), which is coupled with real-time imaging to track and compensate for the patient s or target s motion. As a relatively non-invasive treatment modality, CyberKnife demonstrates certain benefits, including a more accurate target localization and improved dose delivery for the management of metastatic brain tumors that allows higher biologically effective dose delivery without increased incidence of toxicity. In the present case, the results for the treatment of multiple brain metastases after CyberKnife surgery with a 7 8 Gy marginal dose was promising. CyberKnife for metastatic brain tumors is an effective and safe method for reducing the marginal dose prescribed for multiple brain metastases and for minimizing the radiation-related neurotoxicities. In conclusion, CyberKnife, a focused, highly-targeted radiosurgery and fractionated radiotherapy is particularly useful for multiple brain metastases. CyberKnife provides the advantage of the management of local recurrence and a tolerable complication rate. Although the treatment of brain metastases has been performed with CyberKnife, the clinical significance and optimal dose fractionation scheme require further investigation. In case you have a concern or query you can always consult an expert & get answers to your questions!
