About Lung Cancer

  • Lung Cancer is in your lungs.
  • It can be caused by lots of things.
  • Smoking, have a history of family with lung cancer,2 hand smoking
  • There are 7 stages of lung cancer


  • Coughing, especially if it persists or becomes intense.
  • Pain in the chest, shoulder, or back unrelated to pain from coughing.
  • A change in color or volume of sputum.
  • Shortness of breath.
  • Changes in the voice or being hoarse.
  • Harsh sounds with each breath (stridor)

Possible causes

  • Smoking causes the majority of lung cancers — both in smokers and in people exposed to secondhand smoke.
  • But lung cancer also occurs in people who never smoked and in those who never had exposure to secondhand smoke.
  • In these cases, there may be no clear cause of lung cancer.

Cancer growth

  • Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs.
  • These abnormal cells do not carry out the functions of normal lung cells.


  • patients are also encouraged to consider clinical trials as an option.
  • Lung cancer treatment depends on the type of lung cancer and whether it has spread. The treatment may include surgery, radiotherapy, and,chemotherapy.
  • In surgery the are going to find the part that has lung cancer and cut it out.
  • Radiotherapy Type of light that goes through skin and kills cancer cells
  • chemotherapy Take medicament that stop the cancer cells from doing the cell cycle.

Survival Rates

  • For instance, 52 percent, or about half, of people diagnosed with early-stage lung cancer live for at least five years after diagnosis.
  • The five-year survival rate for people diagnosed with late-stage lung cancer that has spread (metastasized) to other areas of the body is 4 percent.

          Stages of Lung Cancer

        In stage 0, abnormal cells are found in the lining of the airways.

        In the occult (hidden)stage, cancer cannot be seen by imaging or bronchoscopy.

    Metastasis-Is when it spreads to another organ

    You have lung cancer in your lungs then it can travel to your heart,kendny,etc

  • Cancer has spread to the innermost layer of the membrane that covers the lung.
  • stage 1 Part of the lung has collapsed or developed pneumonitis (inflammation of the lung) in the area where the trachea joins the bronchus.
  • Stage 2 is divided into stages IIA and IIB. Stage IIA and IIB are each divided into two sections depending on the size of the tumor, where the tumor is found, and whether there is cancer in the lymph nodes.
  • stage 3 is divided into three sections depending on the size of the tumor, where the tumor is found, and which lymph nodes have cancer (if any).
  • stage 4 is divided into two sections depending on the size of the tumor, where the tumor is found, and which lymph nodes have cancer.
  • in stage 5 the tumor may be any size and cancer may have spread to lymph nodes. One or more of the following is true:


  • When first diagnosed with cancer, many people ask about their prognosis.
  • You might want to know whether your cancer is relatively easy or more difficult to cure.
  • Your doctor can't predict the future, but can make an estimate based on other people's experiences with the same cancer.
