Lung Cancer-Signs, Stages, Symptoms, Causes, Risk Factors & Treatment

As we all know lung are the two spongy organs present in the chest that takes oxygen during inhalation and leaves out carbon dioxide during exhalation. Cancer that develops in this spongy organ is called a lung cancer, which is nowadays a leading cause of death in both men and women all over the world.

Signs and symptoms of Lung Cancer that should not be amiss

Now you must be wondering how you know that you are suffering from lung cancer. Let’s discuss some of the common lung cancer symptoms. At the initial stages lung, cancer doesn’t show any symptoms. It starts showing a sign when it is at an advanced stage. But some of the early signs, if they are well observed, can be treated easily. Some of them are:

  • A chronic cough that doesn’t quits for a long time
  • A cough that produces blood or more amount of mucous.
  • Breath shortness
  • Weight loss
  • Pain in the chest area, shoulders, and back.
  • Voice hoarseness
  • Pain in bone
  • A headache
  • Wheezing

Symptoms of lung cancer

Stages of lung cancer;

The stage of lung cancer is very important that helps in knowing about the location of the cancer cells, size of a tumor and how much cancer has spread. Depending on the Stages of cancer the treatment is decided. The staging of lung cancer is denoted by the letter T, N, and M. The letter T stands for the size and the location of a tumor in the lung

The letter N stands for the involvement of the node and the letter M stands for metastasis or how much cancer has spread to other regions. Lung cancer is two types, small cell lung cancer, and Non-small cell lung cancer. Each type has different stages:

Stages of small cell lung cancer:

  • Limited stage: In this stage, the cancer is just in one lung and mostly in the lymph nodes.
  • Extensive stage: Here cancer has already spread to other areas of your chest and lung.

Stages of non-small cell lung cancer:

  • Occupant stage: It is a stage in which the doctor cannot see the cancer cells in biopsy or scans, and they are usually picked up in the mucus that has come out during coughing.
  • Stage 0: At this stage, the tumor is very small and the cancer cells have not spread to deep, lung tissues.
  • Stage 1: Here the cancel cells is in tissues of the lung and not lymph nodes.
  • Stage 2: cancer spreads to the lymph nodes
  • Stage 3: Here cancer spread to the lymph nodes and other areas of the chest.
  • Stage 4: in this stage cancel cells spread to the other parts of the body.

Causes of lung cancer

There are various causes involved in lung cancer among which smoking is the major cause. Both active, as well as passive smokers, are prone to lung cancer. Now you must be thinking how smoking causes lung cancer? Well! Smoking results in the destruction of the lining of the lung. The smoke contains carcinogens that destroy the lung tissue.  Initially, your own body may repair the damage but with increased exposure, it fails to repair for which the normal cells start getting destroyed and these damaged cells may behave abnormally giving rise to cancerous cells.

But it doesn’t mean that a person who never smokes can never develop lung cancer. There are several other reasons that cause various types of lung cancer other than smoking.

Air pollution: It is another major cause of lung cancer. Pollution occurring because of exhaust from vehicles, wood stoves, power plants, and some other sources can trigger the development of cancerous cells. The smoke accumulating because of this air pollution is highly carcinogenic and leads to the development of lung cancer.

Mutations: This is another reason behind lung cancer and can be transferred from one member to another member of the family.

Risk factors

There are a number of factors that increase the risk of lung cancer occurrence. Some of them are:

  • Exposure to passive smoking: Persons who are not smoking directly but getting exposed to cigarette smoke also runs a high risk of developing lung cancer. This is because of the carcinogens present in the cigarette smoke.
  • Radon gas: The uranium present in the rock, water, and soil undergoes a natural breakdown to produce radon that gets exposed to the atmospheric air. When a high amount of this radon accumulates in the air, it enters your lung while breathing thus becoming a major factor for the development of cancer cells.
  • Asbestos exposure: When you work in an area that has maximum exposure to asbestos and other carcinogenic substances like nickel, chromium, and arsenic, it sometimes leads to the development of cancerous cells.
  • Heredity: Individual who has a family history of lung cancer have an enhanced risk of lung cancer.

However, by following certain tips we can prevent lung cancer. Some of the major steps which we can follow to prevent lung cancer are as follows:

  • Quit smoking: As we all know that smoking is the major reason behind lung cancer, therefore, the best way to prevent it is by quitting it altogether, before you develop cancer. It is also very important for parents to develop awareness among children’s not to smoke so that they will not develop the risk of getting affected by lung cancer.
  • Avoiding passive smoking: If you are staying nearer to an active smoker, then it’s better either to avoid them or to tell them to smoke away from you.
  • Avoiding use of carcinogens at the workplace: By taking proper precautions at the workplace to avoid toxic chemicals can help you in preventing lung cancer. Some of the major precautions which you should take while handling chemicals are wearing a face mask, avoiding direct contact with the chemicals
  • Maintaining a healthy lifestyle with good food and exercise: This is one of the most common reasons to avoid any sorts of disease in life. When you will eat good food and do regular exercise, then there is the least chance of getting affected them with any type of diseases.

  • Imaging test: By taking the X-ray image of the lung your doctor can easily rule out the presence of any abnormal nodule. However, lesions cannot be seen in x-ray but rather in CT scans.
  • Cytology of sputum: While having a cough if you develop sputum, then a microscopic examination of this sputum can show the cancer cells.
  • Biopsy: It involves removing a sample of abnormal cells from the lung and conducting a biopsy in various ways like bronchoscopy, mediastinoscopy.

A combination of drug is given in a series of weeks or months, with some breaks in between. Sometimes chemotherapy is used before surgery so that the cancer cells will shrink and it becomes easier to remove them.
  4. Radiosurgery: It involves treatment with intense radiation that puts radiations from various angles in the cancer cells, thereby destroying it. It is usually for people with small lung cancer.
  5. Therapy involving targeted drug: In these drugs are recommended that helps in destroying some specific causes inside the cancer cells that are causing the abnormal growth of the cells.
