Types of Lung cancer that you need to know now!

Overview

Lung cancer is the biggest cause of cancer death with high mortality rate & the second most diagnosed cancer in both men and women. As fewer people smoke cigarettes after increasing for years, lung cancer rates are now decreasing nationally.

When cancer starts in the lungs, then, it is called as lung cancer.

Cancer is a disease in which normal cells change into abnormal harmful cells called as cancer. Eventually, these abnormal cells multiply to form clusters called Tumors. These tumors grow and start to destroy healthy tissue of the lungs.

Lung Cancer may also spread to other parts of your body if you are unaware of cancer spread in the body. Cancer may spread to other parts of the body through blood or lymph fluid, which is a natural substance that gathers unwanted waste material.

 

Lung Cancer are broadly classified into 2 major types

  • Small Cell Lung Cancer &
  • Non- Small Cell Lung Cancer

Small Cell Lung Cancer

This is less common than NSCLC. A study states that SCLC accounts for 13% of all Lung Cancer. This type multiplies rapidly and grows uncontrollably of all other types.

SCLC grows quickly and travels to other parts of body and increases the risk of metastasis of cancer in other parts.

 The diagnosis is often made very late as there are minimal Symptoms and till then your Cancer is spread to other parts of body including lungs. Thus, recovery chances are very less but if diagnosed in early stages, you can put control and  treat it. 

Smokers are more likely to get SCLC.

Non- Small Cell Lung Cancer

It is most common lung cancer accounting for 80- 85% of all cases. NSCLC is broadly classified into 3 types.

Adenocarcinoma

At the beginning, Cancer may occur only in the top layer of the esophagus lining. At this stage, it’s easier to cure.

As it advances, cancer may expand deeper in the wall of the esophagus. As it further expands, it may invade your another organ. It may risk your life when it further reaches to Lymph Node. When Cancer reaches the Lymph node it may expand to any part of the body along with the lymph fluid.

When diagnosed in chest X-ray it may fool you as a Pneumonia.  

Adenocarcinoma is common in lungs, but it also spreads to other organs like:

  • Stomach
  • Thyroid
  • Breast
  • Pancreas
  • Prostrate
  • Cervix

Squamous Cell Carcinoma

Squamous cell Carcinoma are the second most common types of skin cancer.

It is more dangerous than basal cell Cancers. They tend to go deeper and spread more easily to the organs like:

  • Mouth
  • Ears 
  • Around the Nose

The majority of Squamous Cell Carcinoma is found in women. If you have recently been diagnosed with Squamous cell Cancer, you really need to look at your skin once a month in the mirror to find whether anything is new, growing, changing or something that is not healing.

Large Cell Carcinoma

Large Cell Carcinoma is one of the several forms of NSCLC. It accounts roughly around 10% from NSCLC. It is also called as diagonal exclusion. Furthermore, it is an undifferentiated carcinoma

Due to the large size of Cancer cells, it can be seen in the tumors when viewed in Microscope.

Large cell Cancer grows more rapidly and is usually larger cells comparatively to other cancer cell when diagnosed

This type of Lung Cancer can be found anywhere in the Lung, but more likely to be found in periphery. The majority of Large cell Carcinoma are found in Men.

Lung Cancer Causes

1) Smoking
Smoking tobacco is one of the major and most leading cause for the lung cancer. Among all deaths, 80% from them are caused due to smoking only. Secondhand smoking is also responsible for the lung cancer.

Smoking makes the person to put in risk for lung cancer.
Not only smoking, but also there are few genetic factors which plays a role in causing the lung cancer.

2) Non smokers

Yes, lung cancer is seen in non-smokers too. It is also seen in people who never smoked. It is very rarely seen in non-smokers affected by lung cancer. This type is known as SCLC, small celled lung cancer.

This is caused by secondhand smoking, air pollution etc. The cubicle of a person which has exposure to the asbestos, diesel (fuel) or any exhaust can also be responsible for lung cancer in non-smokers.
