Lung Cancer: Symptoms and Types, Treatment and Outlook

One of severe and life-threatening types of cancer the person may experience is the lung cancer. The worst is that the lung cancer is not feasible to reveal at early stages due to absence of obvious and typical symptoms.

Symptoms of Lungs Cancer

However, with the lapse of time people affected with this diseases start to develop the signs as follow:

  • Weight of loss and persistent fatigue;
  • A cough with the blood in mucus;
  • Painful breathing;
  • Painful coughing;
  • Forceful coughing;
  • High blood temperature and sweat at nights;
  • Regular respiratory distress.

If you find any of these conditions in you that last for considerable amount of time, you’d better seek for the medical consultation.

Types of Lung Cancer

The primary lung cancer is the cancer that develops in the lungs first. This is how it differs from the secondary lung cancer when it develops in other body organs and metastases are then spread to lungs. This article is about the first case of primary lung cancer.

In general, the primary lung cancer type classification refers to 2 types depending on where the cancerous cells start to develop. These are the non-small-cell lung cancer and small-cell lung cancer.

They differ as follow:

  • non-small-cell lung cancer is more common than the second type. It is diagnosed in more in 80-85% cancer cases. This, in turns, is classified in subtypes that are treated differently since they start in different parts of lungs and develop differently. Adenocarcinoma, squamous cell carcinoma and large-cell carcinoma refer to these subtypes of non-small-cell lung cancer.
  • small-cell lung cancer is reported in fewer cases as compared with the non-small-cell lung cancer. It differs in that it develops faster, the abnormal cells grow to be out of control and may spread to other organs.

So, the cancer therapy differs depending on the type of cancer you develop.

Who’s Affected

Lung Cancer: Symptoms, Causes and Treatment

As a rule, older people (from 70 to 75) refer to the most vulnerable group of population to be diagnosed with the lung cancer. It is not normally found in people younger than 40 though it depends, and in most cases the lung cancer cases rapidly grow with the age.

One of the proven causes of the lung cancer is smoking. It is the underlying cause of more than 85 % cases of cancer though non-smokers can be also affected. When smoking, the lungs of smokers get poisoned with the toxic smoke of tobacco and other substances and they further remain in lungs. The longer one smokes, the higher is the risk to develop conditions above.

Treating Lung Cancer

If diagnosed on early stages, the lung cancer may be treated well, though it depends on the type of cancer, rate of the disease development and, to the considerable extent, on the health state of the person affected.

In case, if the specialists diagnose the lung cancer in you at early stages with abnormal cells that affected the smaller area, these foci may be recessed by the surgeon to get rid of any cancerous cells.

Radiation therapy is generally the method to manage the lung cancer in cases when surgery is not indicated.

In severe cases, when first two methods above are not applicable, when the cells grow too fast or wide, chemotherapy is recommended.


The absence of conditions listed above is not the reason to exclude the lung cancer. Unfortunately, the one affected with this disease cannot reveal symptoms or signs until the cancer develops too strong to affect the entire lungs or spread metastasis to other adjacent organs.

As per statistic data, when the lung cancer is diagnosed at later stages, one-year survival rate is reported for 1 of 3 persons affected with the disease and ten-year rate for 1 of 20 persons due to other factors.

In all and any case, early diagnostics can be the effective tool to diagnose the cancer at early stages when it fits for surgery or other therapies for successful outcomes. Yet, the cancer management outcome depends on many factors, including the spread of metastasis and, first of all, on timeliness of diagnostics.
