What is Lung Cancer?

Lungs are located in the area of the chest. These lungs are one of the most important organs of the body and maintaining its proper health is very essential. The main function of lungs is exchange of respiratory gases, namely oxygen and carbon dioxide. Oxygen is inhaled through it and passes on to the bloodstream in the body. They also purify the lungs before releasing it in the blood. On the other hand, carbon dioxide is removed from the body through them. There are two lungs, one on the right and the other on the left. It is made up of various parts. Lung cancer is excessive growth of the tissue cells in the lungs. It can affect any part of the lung and is of malignant kind.

Types of Cancer

Lung cancer is a malignant cancer. It means that it can spread from lungs to other parts of the body also. It can occur when the cancer from other parts of the body enters into the lungs also. In this cancer, the cells multiply at a faster rate and spreads throughout the system. This type of aggressive and extensive growth is cancerous. There are two main categories – small-cell cancer (SCLC) and non small-cell cancer (NSCLC). NSCLC is the most common type and almost 80% of the cases are of it. It is further divided into categories also. SCLC is another type which accounts for 20% of the cases and is caused mainly due to smoking.

Causes

Smoking is considered to be the most common cause of the cancer. Almost 90% of the cases reported are tobacco related. Risk of cancer increases ten fold because of smoking of any type of nicotine. Passive smokers are also at a risk as they inhale smoke released by others. Another common cause is asbestos fibers that are responsible for infections to lungs. Radio gas is a chemical gas that affects lungs and almost 12% of cases are caused due to it. There are certain diseases that also increase cancer risk considerably. Air pollution and previous history of lung cancer are other causes of lung cancer.

Staging and Treatments

There are various stages in the process of cancer. Staging is important in determining the course of treatment. The first stage is when the cancer is limited to lungs only. In the next step, it is spread over the area of chest. Even in the third stage, it is confined to chest only. In the last stage, it starts spreading over to the other areas. Treatment for each stage is different. It can be removed through surgical procedures. There are chemotherapy and radio therapies also which are often used for early stages.

Few Paths of Preventing Lung Cancer

In most countries and world wide statistical reports on medical issues show that cancer is a large reason for death these days. Among the various types of cancers, the cancer of lungs kills the maximum number of people every year in different countries. The disease is almost incurable at a developed stage and has very little chances of getting cured during the initial stages. Patients suffer with too much pain and have to undergo a huge trauma with torture while the lungs are getting damaged every now and then by the cancer cells. The statistical data along with the painfulness might show how dangerous the disease is but it hides a fact that might be like a silver lining to all the above facts. Lung cancer is the easiest to prevent among all. Some of the preventive measures for the deadly disease could be the following.

Exercises with proper diet

Since ancient times, especially in the Hindu civilizations of Indian subcontinent, exercises were deemed to be the best prevention to diseases. No doubt this fact can still not be debated with any logic and it stands true even here in England. Going to the gymnasium is neither always possible nor required. Freehand workouts if done with proper intake of diet can make wonders in keeping many fatal diseases away including Lung cancer. Remember the proverb ‘an apple a day keeps the doctor away’? Yes, all fruits and vegetables must be included in your daily food items list to make your diet perfect to prevent all sorts of diseases.

Give up smoking as well as passive smoking

The above three words are easier said than done, but has no other alternative because studies show most lungs cancer patients were chain smokers and logically too it is a cause of cancer. Tobacco in all forms is a carcinogen and should be always avoided to keep cancer away. Tobacco may not only get into the body with direct smoking of cigarette but via passive smoking too. The latter case is more dangerous for Lung cancer as the smoke inhaled is not at all filtered. Ask friends and others not to smoke in front of you. Use your legal right to ask others not to smoke in smoke free zones. Do not visit those places where you might find huge number of smokers.

Giving regular visit to doctor

It is easy to heal a disease during its initial stages than at a mature level. Most diseases can be detected at a developed stage only. Visiting a doctor for periodic check-ups can help to keep a watch on our body’s condition and with that it will be easier to diagnose the disease more easily.

Conditions that are indicative of lung cancer

Conditions that are indicative of lung cancer

Conditions That Are Indicative of Lung CancerAt the initial stages of cancer of lungs, one may not be able to identify it as cancer without proper physician’s guidance. During the initial stages of the cancer of lungs, body exhibits very common symptoms of certain illnesses that are not much serious. No symptoms could be found in some people suffering from lungs cancer. That is why; it is difficult to treat lungs cancer as once the stages develop without any warning before hand, as the disease gets critical and tougher for treatment. Physicians state that patients of this dangerous disease could not understand anything from before, so that he could have come for treatment at an earlier stage.

Visit to the physician – a must

If you are having the habit of visiting your family physician periodically then it is a good practice or else start developing the habit. Some doctors are very careful about checking for the symptoms for lung cancer, but some do not want to check for them. If your doctor is from the latter category ask him to see whether there are any potential dangers of cancer in you. He might then test for it considering your habits, age and genetic background. If you are a chain smoker then there are higher risks for the cancer in lungs. If your age is more and you have been exposing your lungs to the harmful tobacco smoke for a prolonged period then it is more likely for you t have lungs cancer.

Some symptoms you may detect at home

Consistently, if you are coughing and feeling irritation in the windpipe then there are reasons to worry. Though, it might not always be indicative of lung cancer but many patients of the fatal disease had experienced such a sign at first. The cells that are on the inner side of the windpipe are affected by tobacco smoke. This is why; the nerves react to it and want to throw out the foreign substance and consequently, the coughing starts in order to dislodge the foreign substance. The desired result of such a coughing is a clear air path but most often the amount of tobacco smoke is high and cannot be cleaned with coughing alone.

Wheezing and bleeding at worse levels

Now since coughing alone might not be the reason for lung cancer but other symptoms like wheezing and bleeding is seen in the matured stages of the disease. It is never so casual for blood to come out with coughing, so doctors’ advice is very important. Though, the symptoms of wheezing and coughing can be seen in the tuberculosis patients too but it might be also a symptom of cancer of the lungs.

Lung cancer and its Symptoms

Lung cancer and its Symptoms

Lung cancer and its Symptoms

Lung is one of the most vital organs of the body. Its main function is respiration and making sure that oxygen that is inhaled reaches all parts of the body and carbon dioxide is exhaled from the body. Cancer occurs when the there is malfunctioning of any cells in the body. Similarly, lung cancer occurs when there is abnormal and excessive multiplication of the cells in the lungs. Cancer is malignant, as it is capable of spreading to other parts of the body. Malignant cancers grow at a very fast speed and spread throughout the body by entering into the blood stream and reaching other organs. This whole process is known as metastasis.

Description

Lung is a very common target of metastasis. Malignant tumors from the other parts spread to the lungs and affect them. Lung cancer is characterized by excessive growth of the tissue cells of the lungs. There are two main types of cancer of lungs, namely small-cell cancer (SCLC) and non-small-cell cancer (NSCLC). In SCLC, the cells contain neuroscretory hormones. It comprises of almost 20% of the cancers of lung and is the most aggressive in its growth. It is more prevalent in smokers then non smokers. It is also known as oat cell carcinomas. NSCLC are the most common type of cancer of lungs. It is subdivided other categories – Adenocarcinomas, bronchioloalveolar carcinoma, etc. There are other types of cancer which are very rare and comprises of about 5 to 10% of cancers.

Signs and Symptoms

Symptoms depend upon factors like the type and extent of the cancer. There are no particular or sure shot signs of it. As a matter of fact at times people who have cancer do not show any symptoms until the later stages. It can be detected through X-rays or CT scans. As the cancer progresses, people start showing signs like problems in breathing which leads to coughing fits, chest pains, or coughing up of blood. If the cancer spreads to the lung then it can cause pain in the shoulder or paralysis of chords. It may also lead to problems in swallowing and can cause various infections also.

When should people start worrying?

It is always advised that everyone should get medical check ups on yearly or half- yearly basis. It helps in detecting problems that we are not even aware about. There are certain signs that should make people alert about lung cancer. Persistent coughing problem and spitting blood while coughing, getting respirator infections very frequently, pains in chest, sudden weight loss or weakness in the body, and if one starts having difficulty in breathing. These are some signs that points towards cancer and should not be ignored.

Women More Vulnerable To Lung Cancer

Cancer had been a very dangerous disease from olden times. Previously, it could not be treated at all and people suffering from this disease were left helpless. Recently, a little improvement has been done in this field by medical sciences but in a limited manner. Yet, there are records of huge number of deaths due to cancer all over the world. The disease may breed with any part or organ of the body. This disease does not discriminate between men or women. However, when we will speak about cancer and women it is vital to remain aware about the fact that women are these days getting more prone to the Lung cancer.

What does statistics about lung cancer in women show?

Statistically, certain facts have surprised physicians, patients, commoners and all. Firstly, women are getting more vulnerable to the cancer of lungs. Secondly, alone in the US, studies and surveys show that around 70K females get preyed by the cancer of lungs. With this you can fairly develop an idea about what could be the condition all over the world. Though, there are few reasons for the concentration of cancer death is more in the developed countries like the US and UK. The social habits and smoking practice of women in these countries make them more susceptible to Lung cancer. A 600 percent increase in cancer deaths for lungs in women had startled medical world during last 80 years. However, a reduction in the rate recently is giving a kind of relief to all.

Why women are getting more susceptible to lung cancer?

Though, smoking habit has been indicated as a very big risk factor for lungs cancer in women many other factors are also responsible. The increase in the habit of smoking in English and American women is a major cause of Lung cancer death in these countries. Genetic reason is one that makes a woman more reactant to carcinogens, a substance causing cancer. When women are exposed to dangerous gases, second hand smoke, asbestos and other air pollutants they readily catch these and become more vulnerable to the cancer of lungs. Estrogens are hormones that may also cause the disease in women.

What made smoking more habitual in women?

Demonstration effect of various cigarette brands has created the trouble of increased smoking habit in women.
