Everything You Should know about Lung Cancer


Everything You Should know about Lung Cancer

If you are suffering from lung cancer, it is important to get treated quickly. This way, you can lessen the risks of further complications and stay protected.

Lung cancer is a kind of cancer that usually starts in the lungs. Your lungs consist of two spongy organs in the chest that take in oxygen at the time of inhaling and release carbon dioxide while exhaling.Lung cancer is considered to be the major cause of cancer deaths all throughout the world.

People who are addicted to smoking have the highest risk of lung cancer, though lung cancer may even occur in people who have never smoked. The risk of lung cancer usually increases with number of cigarettes you smoke and the length of time. If you quit the habit of smoking, then you can possibly lessen the chances of developing lung cancer.


Lung cancer usually does not show any signs and symptoms at its early stages. Signs and symptoms of lung cancer usually occur when the disease gets advanced.

Signs and symptoms of lung cancer consist of the following:

  • New cough that do not go away suddenly
  • Coughup even small amount of blood
  • Shortness of breath
  • Hoarseness
  • Chest pain
  • Lose weight without trying
  • Headache
  • Bone pain

When you need to visit a doctor

You should schedule an appointment with your doctor when there are any persistent signs or symptoms that might worry you. If you smoke and cannot quit, fix an appointment with your doctor for private health screening service. Your doctor may suggest effective strategies to quit smoking such as medications, counseling and products for nicotine replacement.


Smoking causes most types of lung cancers, both in case of smokers and in people who are exposed to secondhand smoke. But lung cancer may occur in people who have never smoked and who do not have prolonged exposure to secondhand smoke. In these cases, there might not be any clear cause of lung cancer.

How smoking can lead to lung cancer

According to the doctors, smoking causes lung cancer by damaging cells that line up your lungs. When you inhale cigarette smoke, which is full of cancer-causing substances or carcinogens, there will be some changes in the lung tissue that usually start immediately.

Your body may repair this damage however, with each repeated exposure, normal cells that line up your lungs get damaged greatly. The damage causes the cells to act in an unusual way and thus, cancer might develop, in due course.

Kinds of lung cancer:

Small cell lung cancer

This usually takes pace in case of heavy smokers and is less common than non-small cell lung cancer.

Non-small cell lung cancer

This is believed to bean umbrella term for different kinds of lung cancers. It includes– adenocarcinoma, large cell carcinoma and squamous cell carcinoma.

Risk factors

Smoking– The risk increases by taking number of cigarettes you smoke daily and number of years you have smoked. Quitting at any age may significantly reduce the risks of developing lung cancer.

Direct exposure to secondhand smoke – If you are not addicted to smoking, then your risk of developing lung cancer increases when exposed to secondhand smoke.

Previous radiation therapy – If you have passed through radiation therapy to the chest for another kind of cancer, then you might have increased chances of suffering from lung cancer.

Exposure to radon gas –Radon can be produced by natural breakdown of uranium in rock, water and soil that generally becomes a part of the air you breathe. Unsafe radon levels may accumulate in any building such as homes.

Family history of lung cancer – People whose parent, sibling or child has lung cancer will experience an increased risk of getting this disease.


Shortness of breath – People who are suffering from lung cancer may face shortness of breath when cancer develops to block major airways. Lung cancer can be the reason for your fluid to accumulate around the lungs thus, making it difficult for affected lungs to expand completely when you inhale.

Coughing up blood – Lung cancer may lead to some bleeding in the airway that can be the reason for coughing up blood or hemoptysis. Sometimes bleeding may get severe and there are treatments available to control this form of bleeding.

Severe pain – Advanced lung cancer that generally spreads to the lungs lining or another part of the body such as bone may lead to severe pain. It is advised to inform your doctor when you suffer from severe pain as proper treatment ca help to ease the discomfort soon.

Fluid in the chest or pleural effusion – Lung cancer might be the reason for your fluid to accumulate in the space that usually surrounds affected lungs in the chest cavity or pleural space. The fluid accumulating in your chest may lead to shortness of breath. There are appropriate treatments available to drain out the fluid from your chest and lessen the risk that pleural effusion will happen again.

Cancer spreading to other body parts or metastasis – Lung cancer usually spreads to other parts of the body such as the bones and brain.Cancer that may spreadleads to pain, headaches, nausea or other signs and symptoms based on the organ that has been affected. Once lung cancer spreads beyond the lungs, it is generally not treatable. There are effective treatmentsto lessen the signs and symptoms so that you can live for a long time.


Quit the habit of smoking – Ifyou have never smoked, it is advised not to start now. Talk to your children about not smoking so that they may understand therisks associated with it. Start your conversations about the dangers of smoking with the children early so that they know how to react to such pressure.

Eat a diet full of vegetables and fruits – Take a healthy diet which is full of fruits and vegetables. Food sources of vitamins and nutrients are considered to be the best option. Avoid taking large doses of vitamins in pill form, as they can be quite harmful for your health.

Exercise daily to stay fit and strong – If you do not perform your exercises daily, you may begin it slowly. This way, you can improve your health condition and maintain a strong and fit body.
