Lung Cancer Prognosis

Cancer in simple words can be described as unregulated or uncontrolled growth of cells. These cells come together to form malignant tumor which is cancerous. However, note that not all tumors formed are cancerous. Benign tumors are considered to be safe and are not cancerous in nature. In the case of lung cancer, the malignant tumor is either originally developed in the lungs which is called as primary lung cancer or the tumor has spread to the lungs from other body parts which is known as malignant lung cancer. The process of cancerous cells spreading to other body parts is termed as metastasis. Lung cancer is the leading cause of deaths due to cancer in the United States. The main reason for the cause is smoking addiction. Researches have proved that people who smoke are at a much higher risk of getting lung cancer than people who do not smoke. So, if you want to reduce the risk of getting lung cancer, quit smoking. It will lead to a better way of living.

Symptoms of lung cancer:

  1. Coughing that gets worse day by day
  2. Pain in the chest
  3. Blood coming out while coughing
  4. Wheezing
  5. Shortness of breath and hoarseness

Above mentioned are few of the symptoms of lung cancer. These symptoms must not be neglected.

Lung cancer prognosis:

Prognosis is the chance the patient has to recover or the risk of recurrence of cancer.

Factors that affect prognosis are:

  1. The person's general health, age, medical history and response to the treatment.
  2. Size and type of the tumor
  3. Stage of the lung cancer and the degree of metastasis and
  4. Vascular invasion

For non-small-cell-lung carcinoma (NSCLC), prognosis is poor. For stage IA disease, the survival rate of five years is 67%, for stage IB disease, the survival rate of five years is 57% and for stage IV disease only 1% people achieve their five year survival rate. In case of small-cell-lung carcinoma (SCLC), prognosis is also poor. About 5% of patients achieve their five years survival rate.

When doctors decide prognosis of a person, he has to consider factors that affect person's treatment and disease and then predict the prognosis. The prognosis is based on the information collected over the years of patients who had lung cancer. When determining the prognosis, doctors may consider the statistics of patients who had similar situation of the disease to the individual patient.

Lung cancer prognosis is unfavorable if the cancer is difficult to treat. This happens when the patients go to the doctor when the cancer has advanced to the later stages or the fourth stage. It is very difficult to eliminate cancerous tumor in the last stage of the cancer i.e. fourth stage of cancer. Lung cancer prognosis is favorable if cancer is well within the control and can be treated successfully. This happens when the cancerous tumor is detected early in the initial stages of cancer.

One must note that prognosis of cancer is only a prediction and doctor may not be absolutely correct about it.
