This question should be answered specifically. Some people may initially experience symptoms such as weight loss and fatigue when they start to develop lung cancer. Some people with better physical constitution may not lose weight so easily. However, if a malignant tumor persists in the body for a long time, it will consume the body's nutrients and lead to a state of cachexia, characterized by systemic toxicity symptoms including weight loss, fatigue, fever, and other similar symptoms.

How is lung cancer caused?

The specific causes of lung cancer are not completely clear, but there are some high-risk factors. Research has shown that lung cancer is influenced by a combination of genetic defects and internal and external environmental carcinogens. It is undeniable that long-term heavy smoking is the most important carcinogenic factor for lung cancer, with the amount and duration of smoking being positively correlated with the incidence of lung cancer. Secondly, environmental factors, such as working with asbestos or in mining areas, are also very relevant to the incidence of lung cancer. Thirdly, irregular eating habits, rest, alcohol consumption, indoor combustion, coal smoke, fumes from kitchen cooking, and carcinogenic substances released from indoor decorations and materials are also related. Fourthly, the body's internal immune status, metabolic abnormalities, genetic factors, and chronic lung infections also have a significant impact.

Causes of Lung Cancer

The most common cause of lung cancer is smoking, but many people who have never smoked also develop lung cancer. One possible reason could be related to kitchen fumes. Chinese cooking habits often involve high-temperature frying and stir-frying. After frying in hot oil, the higher the temperature, the more harmful substances are in the fumes, which over time could lead to lung cancer. Some patients develop lung cancer due to air pollution; secondhand smoke is also a significant cause. For example, if a husband smokes, the likelihood of his wife developing lung cancer is more than 200% higher than in the general population, indicating that smoking harms not only the smoker but also their nearest and dearest family members. Additionally, there are other potential causes including psychosomatic factors such as chronic insomnia, depression, decreased immunity, genetic factors, and more.

What is the treatment for lung cancer?

Treatment for lung cancer should be based on the pathological staging, the pathology type, the biological behavior of the lung cancer, and individualization, taking into account the patient's cardiopulmonary function and overall systemic condition to develop a personalized treatment plan. For non-small cell lung cancer and small cell lung cancer, the treatment approaches differ significantly. Therefore, it is advisable for patients to seek treatment at specialized hospitals, under the guidance of oncology specialists. Generally, treatment options for non-small cell lung cancer include surgical resection, adjunctive chemoradiation, neoadjuvant chemoradiation, targeted therapy, and immunotherapy. For small cell lung cancer, a comprehensive treatment plan combining chemoradiation, along with prophylactic cranial irradiation and other aggressive treatments, is recommended. Each individual's situation might differ, so it is important to focus on a personalized comprehensive treatment plan rather than a one-size-fits-all approach.

How long can one live with lung cancer?

The survival period of malignant tumors is a topic of great concern to everyone. The question of how long one can live with lung cancer is very difficult to answer. It should be based on the patient's physical condition and the pathological staging. However, these judgments are only based on a predictive basis and do not determine how long the patient can live. If the patient does not relapse after surgery, is sensitive to radiotherapy and chemotherapy, and shows no signs of recurrence or resistance, then their five-year survival rate is naturally higher. If the patient experiences recurrence and metastasis after surgery, then the five-year survival rate is naturally lower. Therefore, the question of how long a person can live with a malignant tumor cannot be answered generically.

Do early-stage lung cancer patients experience vomiting?

If a patient develops lung cancer, some may experience symptoms of nausea and vomiting in the early stages, which is caused by the spread of cancer cells. Others may experience localized pain. It is suggested that lung cancer patients who experience nausea and vomiting adopt a fasting method for treatment, or treat it through localized massage. If patients discover that they have lung cancer, it is crucial to control it in the early stages to prevent the spread of cancer cells. If necessary, treatment can be administered through chemotherapy drugs or radiation therapy drugs.
