Don’t be careless. Even non-smokers can get lung cancer.
Lung cancer Most patients with lung cancer in the early stages do not show any symptoms. However, there will be signs indicating the disease when the cancer grows or starts to spread. Lung cancer can be cured if detecte in the early stages.
What causes lung cancer?
It is caused by the rapid and uncontroll growth of ยูฟ่าเบท https://ufabet999.app abnormal cells. Which results in a cluster of abnormal cells. It can detecte when it is large and has spread to various organs. Lung cancer can divide into 2 types:
1. Small Cell : The cells grow and spread very quickly, causing the patient to die quite quickly. This type of is not very common, about 10-15%. It is divide into 2 stages:
- Limited Stage In this stage, the cancer is only in the lungs.
- Extensive Stage: This stage is when the cancer has spread to other parts of the body.
2. Non-Small Cell : This type of spreads more slowly. If detected early, can be cured by surgery. This type of cancer is found in approximately 85-90% and is divide into 4 stages:
- Stage 1: Cancer is found only in the lungs, not in the lymph nodes, and the cancer cells have not spread.
- Stage 2 is divide
– Stage 2A: The is small and has spread to lymph nodes at the base of the lung.
– Stage 2B: The is slightly larger and has spread to lymph nodes at the base of the lung, or the cancer cells have spread to other areas, such as the chest wall. - Stage 3 is divid into
– Stage 3A: Cancer cells have spread to lymph nodes in areas away from the lungs. Or cancer is found in lymph nodes around the lungs and cells have spread to the chest wall or mid-chest area.
– Stage 3B: Cancer cells have spread to lymph nodes on the other side of the chest or to lymph nodes above the collarbone, or there is more than one tumor in the lung, or the tumor has grown to another part of the chest, such as the heart or esophagus, or there is fluid containing cancer cells around the lungs. - Stage 4: At this stage, the cancer has spread to other parts of the body, such as the bones, liver, or brain.
Risk factors for lung cancer
Although the exact cause of lung cancer is still unknown, there are some factors that may increase your risk of developing it, such as:
- Smoking is a major factor in the development as well as other types of cancer. Smokers are at higher risk of developing than non-smokers.
- Cigarette smoke: Even if we don’t smoke, inhaling cigarette smoke can leave toxic residues that can cause cancer.
- Working in industries that contain carcinogens, exposure to carcinogens such as chromium, radon, and nickel.
- The environment with toxic dust such as PM 2.5 dust. Studies have found that PM 2.5 increases the risk by 1-1.4 times. Which is consider as serious as smoking.
- Genetics is not directly inherit, but it has found. That if there is a family history of lung cancer at a young age, family members are also at a higher risk.
