Lung Cancer - Early Signs, Causes, Prevention and Treatment

17 February, 2021 Ananya Das

Cancer that develops or starts from the lung cells is known as lung cancer. Our body consists of 2 sponge-like organs which are present at two sides of the chest and are the main parts of the respiratory system, called lungs. The size of both the lungs is not the same. Left lung is smaller than the right lung because on the left side of the chest, our heart is present which takes more space.

Lungs consist of lobes in the quantity of 3 in the right lung and 2 in the left lung. When the genes of the lung cells undergo mutation, changes take place in the DNA which affects the working of the cells. As a result, the cells start to grow uncontrollably which leads to the development of cancer in the lungs.

What are the early signs of lung cancer?

The signs are usually not visible at the early stages of lung cancer but in advanced stages it may be found. Following are the signs and symptoms that if encountered you may know either you are diagnosed with lung cancer or not.

  • Chest pain
  • Pain in bones and joints
  • Sudden Weight loss
  • Chronic coughing, sometimes with blood
  • Breathlessness
  • Headaches
  • Sore throat and roughness

Causes of lung cancer:

There are various causes for lung cancer. Some of these can be controlled and some which can’t be controlled but only can be taken care of.

  • Smoking: Smoking is the major cause of lung cancer. If you are a smoker and have a habit of smoking daily then with each cigarette you consume, the chances of developing lung cancer increases. The smoke gets accumulated in your lungs which reduces or affects the working capacity of your lungs.
  • Second hand smoke: Smoking cannot solely be evaluated on the basis of doing deliberate intake of cigarette. Smoke intake has second hand sources too like smoke from burning wooden chulas, vehicle emission, industrial gaseous waste discharge like asbestos and any more. Smoke in any form is harmful for both smokers and non-smokers.
  • Exposure to radon gas: One of the reasons for lung cancer may be naturally occurring radon gas that comes from radioactive activity of the soil and rock. This gas has no smell and color hence it is called a silent gas but if exposed to it frequently or for a long time, then you may end up developing lung cancer.
  • Family history: If you have any member of your family or any ancestor suffering from or have suffered from lung cancer then you have a higher probability of developing lung cancer.

How to prevent lung cancer?

Here are listed below some of the steps one can take in order to prevent Lung cancer.

  • Quit smoking: If you have a habit of smoking daily, it’s suggested for you to stop. If smoking is reduced and eventually stopped at an early stage then the risk of developing lung cancer also reduces. Being a parent, you should talk to your kids about the harms caused by smoking so that they don’t fall into this.
  • Avoid second hand smoke: It’s difficult to avoid these sources but what we can do on our part is take precautions. Try to keep your mouth and nose covered when going out to areas that consist of second hand smoke.
  • Fill your plate with naturals: Eat plenty of colorful fruits and vegetables because these are rich sources of anti-oxidants, vitamins and nutrients. The presence of these may help to fight the cancer developing cells and prevent its development. Cancer Patients Healthy Diet
  • Perform Pranayamas: Try to do breathing exercises as much as you can. It helps to reduce the chances of developing cancer cells in and around the lungs.

Treatments suggested for lung cancer

If you are diagnosed with lung cancer then the treatment method to be used to treat may depend on various factors including your health condition, type of cancer and the stage of the cancer particularly. Some of the treatment ways that can be implemented are as follows:

1. Chemotherapy: In this method, the patient is totally kept on medicines that kill the cancer cells. They are injected in the body or are taken orally. This method can be used with radiation therapy or even post surgery.

2. Targeted drug therapy: Certain drugs are prescribed and taken to block the performance and growth of cancer cells. This method is applied to patients who are at advanced stage or have recurred cancer.

3. Immunotherapy: In this, your immune system is stimulated using drugs to identify and fight the cancer cells and kill them. The cancer cells produce certain proteins that hide them from the immune cells. This therapy is used for the patients who have reached the advanced stage of lung cancer.

The other methods that can be used to treat lung cancer depending on various factors include surgery and radiation therapy. All the medicines prescribed to be used during the treatment of lung cancer are available online which you can easily purchase from online medical stores.
