Lung Cancer, Its symptoms and treatment

Cancer usually arises in a single cell, the cell's progress from normal to uncontrolled growth and sometimes spread to other locations in the body via lymph or blood. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. It usually grows and spreads more slowly than small cell lung cancer.
   


Three forms of NSCLC
  1. Adenocarcinomas are often found in an outer area of the lung.Squamous cell carcinomas are usually found in the center of the lung by an air tube (bronchus).
  2. Large cell carcinomas can occur in any part of the lung. 
  3. They tend to grow and spread faster than the other two types.
Smoking causes most cases of lung cancer. The risk depends upon the number of cigarettes smoked every day and for how long someone has smoked. Being around the smoke from others (secondhand smoke) also raises your risk for lung cancer. However, people who do not smoke and have never smoked have become sick with lung cancer.

Early lung cancer symptoms
  • Cough that doesn't go away
  • Coughing up blood
  • Shortness of breath
  • Chest pain
  • Loss of appetite
  • Losing weight without trying 
 Other symptoms that may be due to NSCLC
  •  Weakness
  • Swallowing difficulty
  • Joint pain
  • Swelling of the fac
  • Bone pain or tenderness
  • Nail problems
  • Hoarseness or changing voice
  • Eyelid drooping
  • Shoulder pain or weakness
Tests that may be performed to diagnose lung cancer
  1. Chest x-ray
  2. CBC
  3. Sputum test to look for cancer cell
  4. Bone scan
  5. CT scan of the ches
  6. MRI of the ches
  7. Positron emission tomography (PET) sca
  8. Thoracentesis
In some cases, the health care provider may need to remove a piece of tissue from your lungs for examination under a microscope. This is called a biopsy. There are several ways to do this:

    * Bronchoscopy combined with biopsy
    * Pleural biopsy
    * CT scan directed needle biopsy
    * Mediastinoscopy with biopsy
    * Open lung biopsy
    * Endoscopic esophageal ultrasound (EUS) with biopsy

Treatment
  1. Surgery is the often the first line of treatment for patients with non-small cell lung cancer that has not spread beyond nearby lymph nodes. The surgeon may remove:
  2. Some patients need chemotherapy. Chemotherapy uses drugs to kill cancer cells and stop new ones from growing.
Prevention
  1. If you smoke, stop smoking. It's never too early to quit. People who have smoked in the past can be at increased risk for lung cancer more than 20 years after quitting, although the risk drops significantly in the first year after quitting. There are benefits to quitting smoking, even for people who are well into middle age.
  2. Try to avoid secondhand smoke.
  3. Eat a diet rich in fruits and vegetables.
Routine screening for lung cancer is not recommended. Many studies have been done to look at the idea, but scientists have concluded that, at this time, screening does not help improve a person’s chance for a cure.

Lung cancer is increasing very rapidly. It ranks second for the most widespread form of cancer. Smoking is major reason for lung cancer, but even non-smokers can suffer from it. Some of the symptoms are regular chest pain, wheezing, bloody cough, weight reduction etc. If anyone observes symptoms of it, should consult doctor immediately.
