Most early-stage lung cancers do not cause symptoms. If symptoms start, it means that the cancer is already advanced. Common symptoms include chronic cough, difficulty breathing, chest pain or tightness, hoarseness, fatigue, loss of appetite, and unexplained weight loss.
Some Facts Related to Lung Cancer
- Lung Cancer has been considered as the second most common type of cancer in both men as well as women
- Many of you might not know that X-rays cannot detect lung cancer in its early stages.
- Of all the deaths that occur due to cancer, lung cancer is the reason for almost 27 percent of the cases.
- Smoking has been considered as the most prevalent risk aspect of lung cancer.
- If you do not smoke that does not mean that you cannot fall prey to lung cancer. Remember that ten to fifteen percent of lung cancer cases comprise people who do not smoke but have other causes for falling ill to lung cancer
Lung cancer diagnosis
Lung cancer diagnosis is divided into คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย 2 groups: those with fairly obvious or suspicious symptoms and those without symptoms. In this regard, people aged 55 and over, even if they have no symptoms but have a history of heavy smoking, are considered a risk group who should be screened for lung cancer using a low-dose CT scan, which will produce a 3D image of the lungs that can detect cancer from the beginning, i.e., with more detail and clarity than a normal chest X-ray, which may not detect it if the symptoms are not severe.
Types and stages of lung cancer
Lung cancer is divided into two types: small cell lung cancer and non-small cell lung cancer. The disease is staged differently as follows:
- There are two stages of small cell lung cancer:
- Stage 1: Cancer cells have not spread and are found in one lung or nearby organs.
- Stage 2: Cancer cells are advanced and have started to spread to other organs in the body.
- There are 4 stages of non-small cell lung cancer:
- Stage 1: The cancer is less than 5 cm in size. Most people do not have many symptoms.
- Stage 2: Cancer cells have spread to the lungs or lymph nodes and may be larger than 5 cm.
- Stage 3: Cancer cells have spread to nearby organs. The tumor has become larger.
- Stage 4: Cancer cells have spread to distant sites, such as the bones, liver, or brain.
