February 9,Kathmandu.Cases of lung cancer are increasing all over the world among people who have never touched a cigarette in their life. A study was published in Lancet on World Cancer Day on February 4. According to this study, 25 lakh lung cancer patients were found all over the world in the year 2022.
Smoking cigarettes increases the risk of lung cancer. The same Lancet study says that the number of cigarette smokers has also decreased rapidly in the last few years. Despite this, cases of lung cancer are continuously increasing.
According to this report of Lancet, in the year 2022, 53-70% of lung cancer cases were seen in people who do not smoke cigarettes. Then what is the reason that lung cancer cases are increasing. According to the report, the biggest reason for this is that the air of the whole world is getting polluted. The dangerous effect of increasing air pollution is visible in the form of increasing lung cancer. Countries like India, China and Thailand are most affected by this.
What is lung cancer?
Lung cancer is a serious disease. In this, the cells of the lungs start growing uncontrollably and gather at one place and form a tumor, which ultimately causes lung cancer.
How many types of lung cancer are there?
Many types of cancer can occur in the lungs, but generally two types of cancer are called lung cancer.
Non-small cell lung cancer (NSCLC)
Non-small cell lung cancer (NSCLC) is a type of cancer that occurs in the lung tissue. 80% of all lung cancer cases suffer from NSCLC. There are mainly two types of it – adenocarcinoma and squamous cell carcinoma.
Adenocarcinoma cancer occurs in the tissues in the lungs that produce mucus or other liquids. According to a Lancet study, in the year 2022, cases of adenocarcinoma cancer were found in people who had never smoked cigarettes.
Of the total cases of adenocarcinoma cancer, approximately 5.5 lakh were women who had never touched a cigarette in their life.
Small Cell Lung Cancer (SCLC)
This cancer spreads quickly and is difficult to treat. Usually, it occurs as a small tumor that begins in the airways of the lungs. It may have spread to other parts of the body before it is detected.
There are also some other cancers around the lungs, which can occur in the bones and the lining of the lungs. However, these are not called lung cancer.
Symptoms of Lung Cancer
The symptoms of lung cancer are mild in the beginning. In many cases, the symptoms are not detected until the disease becomes severe. However, some people may show symptoms in the early stages itself.
stage of lung cancer
There are four stages of lung cancer. It is decided on the basis of the size of the tumor. It is also seen whether the cancer has spread to the surrounding tissues, lymph nodes and other organs. Lymph nodes are a part of our immune system, which protects the body from viruses and bacteria.
Stage 0: This means that the cancer is still only in the upper layer of the lung or bronchus. It has not spread to other parts of the lung or beyond. Bronchus is the tube through which air enters the lungs.
Stage I: Cancer is growing inside the lungs but has not yet started to spread outside the lungs.
Stage II: The cancer has spread to lymph nodes within the lung, or more than one tumor has formed in a single lobe (part of a lung).
Stage III: In this stage, the cancer has spread to nearby lymph nodes or to different lobes of the same lung.
Stage IV: In the fourth stage, the cancer has begun to spread to other parts of the lung, the fluid surrounding it, the heart, or other parts of the body.
Ways to prevent lung cancer
To prevent lung cancer, first quit smoking. Smoking is the biggest cause of lung cancer. Also, you can avoid lung cancer by adopting a healthy lifestyle.
stay away from cigarettes and tobacco
According to WHO, smoking is the biggest reason for the increasing cases of lung cancer. According to a Lancet study, in the next 5 years after quitting smoking, the body recovers itself and the risk of lung cancer also decreases.
Eat a healthy diet
A diet rich in seasonal fruits, vegetables and fiber is helpful in preventing cancer. Also, antioxidants rich foods are good for lung health.
Do breathing exercises
Regular exercise keeps the body healthy and helps reduce the risk of cancer. Also, breathing exercises keep the lungs strong.
Take care of lung protection
If you work in a factory where you are exposed to poisonous gases or toxins, take special care of safety. Wear a mask and use a ventilation system while working.
Install an air purifier
If you live in a polluted area or city, get an air purifier installed in your home. It cleans the air and protects the lungs from pollution.
Get regular health checkups
If you are at risk of lung cancer or someone in your family has had this disease, get tested immediately if symptoms appear.
