Why 2 lungs of humans are not equal in size

Do you know why 2 lungs of humans are not equal in size? Number of lobes is also different in two lungs. In our bodies different vital organs present in asymmetric manner. Left lungs are narrower than right lungs.

Our hearts present on the diaphragm on the left side. So it needs space to accommodate the heart. So space required on the left side. The narrow shape of the left lung gives space for the heart. On the other hand, the right lung is flatter than the left lung.

On the right side the liver is present. And according to the shape of the liver the shape of the right liver is also flat. And for this reason on the left side it has 3 lobes and on right side it has 2 lobes.

Queries related to lungs:

What are the early symptoms of lung cancer?

Ans: In males common cancer is lungs cancer. It most reported in males than females. Unfortunately in the initial stage it does not show notable signs that indicate cancer. In most of the cases people know about it when it is at last stage. Less than 11% are able to know at the initial stage.

In most of the cases when it diagnosed it is too late. It then already spread out of lungs. In early stage it may show cough with blood, chest pain which is persistent, shortness of breathing, infection again and again in chest.

These symptoms are generally observed when cancer is in lungs. But when it spread to other organ then it show other symptoms in other organ like brain, lymph, bone. In advance stage it starts to show more symptoms. Cough with 

, bone fracture, fatigue without much work or exercise, weakness even if you are not doing hard work, very low pitch of voice, headache, weight loss. 

How many lung cancers are observed?

Ans: Its short answer is two types. 1. NSCLC : it is most common. In every year about 85% lung cancer are categorised under it. It is non small cell lung cancer. 2. SCLC : it is a rare case. About 10-15 percent cases are categorised under it. It is small cell lung cancer. 

How can lung cancer be diagnosed?

Ans: Cancer can be diagnosed finding cancerous cells. X-ray, CT scan, MRI, PET can show abnormal tissue on lungs which can be suspicious. Any lump of tissues or lesions may be a sign. Cough sputum can reveal cancer cells. It can be observed under a microscope to find cancer cells. Biopsy to collect the tissue of lungs and testing the tissue can reveal cancer. 

What is the survival rate of lung cancer?

Ans: Survival rate means for how long a person with lungs cancer can be alive after the person diagnosed with lung cancer. It is not the same for all people but it can give an idea and give inspiration for treatment. But if you discuss it with the doctor it can be better to predict more accurately.

Because conditions for all people are different so survival rate may vary from person to person. Survival rates are represented by a 5 year survival rate. It means what percent of people are alive now who were diagnosed with cancer 5 years ago. It is different for different types of lung cancer.

Localized non small cell cancer survival rate is 63 percent. Regional non small cell lung cancer survival rate is 35 percent. Distant non small cell lung cancer survival rate is 7 percent. All stage combined non small cell lung cancer survival rate is 25 percent. All stages of small cell lung cancer survival rate is 6.5 percent.

What are the risk factors of lung cancer?

Ans: Risk factors means which induce or promote lung cancer. Smoking is a major risk factor for lung cancer, especially small cell lung cancer. More than small cell lung cancer is due to smoking.

It is a rare case when a person has small cell lung cancer without smoking. A person’s smoke determines how much he or she is prone to lung cancer. More a person smokes more is the probability for having lung cancer. 

Radon is also responsible for lung cancer. It occurs in the atmosphere in natural conditions. But we can not see it or smell it. If the level of radon in the atmosphere is high then it can cause lung cancer. Indoor radon levels are higher than outdoor radon levels.

So the indoor atmosphere is sometimes more harmful. Exposure to asbestos may cause lung cancer. Workplaces where there is a lot of exposure to radon should take precautions. Some other chemicals are also responsible for lung cancer.

Arsenic (a high level of arsenic in drinking water is responsible for lung cancer ), silica, beryllium, and cadmium are known for lung cancer. Radiation therapy also induces lung cancer if radiation therapy is taken by any organ near the lungs.

Radiation therapy for breast cancer is something that causes lung cancer. Sometimes it is caused by genetic issues. If family history has lung cancer then there is more risk for lung cancer.
