Don’t be careless if you experience these 5 abnormalities in your body, they may be signs of lung cancer!

Recently, according to Beijing Youth Daily, Mr. Li Chao, a young crosstalk artist and language director of the CCTV Spring Festival Gala, died in Beijing at the age of 34 due to ineffective treatment of advanced lung cancer.

When netizens heard the sad news, they all expressed their regret, saying that God is jealous of such a talented person!

Lung cancer is currently the number one killer among all malignant tumors, ranking first in both incidence and mortality.

Although lung cancer generally still "favors" middle-aged and elderly people, the trend of lung cancer becoming younger has been very obvious in recent years.

Why do people get lung cancer at such a young age?

Some respiratory medicine experts said that most lung cancers are caused by "anger".

Although the cause of lung cancer is still not very clear, the current occurrence of lung cancer, especially the high incidence in my country, is closely related to smoking. About 3/4 of patients are diagnosed with the disease due to smoking or secondhand smoke.

Especially for those who start smoking before the age of 20, 25% will suffer from lung diseases and are prone to lung cancer; and those who have smoked for more than 20 years and smoke more than 20 cigarettes a day are at high risk of lung cancer.

In addition, according to the latest information released by the World Health Organization, lung cancer is closely related to environmental pollution such as haze weather, PM2.5, kitchen fumes, house decoration, etc. It is also related to our cancer personality, that is, psychological pollution.

Although lung cancer is difficult to detect in its early stages and is often already in the late stages once discovered, it is not without signs.

Part of the reason is that early signals are ignored, so it is important to understand the relevant signs of lung cancer. Once these symptoms appear, you must be vigilant and seek medical attention as soon as possible.

01

trouble breathing

Although only a small number of patients will experience dyspnea in the early stages of lung cancer, once dyspnea occurs, you must be alert to the signs of lung cancer and it is important to be vigilant.

02

Hoarseness

Hoarseness and tightness in the throat are symptoms of lung cancer.

Hoarseness is caused by lung cancer metastasizing to the mediastinal lymph nodes and invading the recurrent laryngeal nerve. Next to the heart, in the mediastinum, there is a nerve that controls the vocal cords, called the recurrent laryngeal nerve. After lung cancer metastasizes to the lymph nodes around the recurrent laryngeal nerve, this nerve is compressed or invaded, and symptoms of hoarseness will occur.

03

cough

The most common symptom of lung cancer is cough. More than half of lung cancer patients will experience coughing symptoms. If you have a dry cough that persists for more than two weeks, you should be careful that lung cancer may be the culprit.

Especially those with a family history of lung cancer and a long history of smoking should pay more attention.

04

Blood in sputum

Some lung cancer patients have blood in their sputum and sometimes cough up blood.

This is because tumor tissue has a rich blood supply, and severe coughing can easily cause blood vessels to rupture and bleed.

If there is always blood in your sputum or you cough up a small amount of blood recently, you need to go to the hospital for relevant examinations in time.

05

Chest tightness, chest pain

Chest tightness and chest pain are also common symptoms of lung cancer. Especially when irregular spasms and dull pain occur, you should be alert to the possibility that they are caused by lung cancer. In addition, persistent pain in the shoulders, chest, back, etc. should also be careful as it may be symptoms caused by tumor metastasis.

Currently, the diagnosis of lung cancer mainly relies on chest imaging examinations.

Since the symptoms of early lung cancer are not obvious, early detection and diagnosis are very important, especially X-ray and CT scans related to lung cancer.

CT examinations, in particular, can detect smaller lesions, and combined with tumor marker tests, they can more comprehensively diagnose early lung cancer.

From the perspective of lung cancer classification, it is mainly divided into central lung cancer, peripheral lung cancer and diffuse lung cancer according to the location of the tumor.

According to the way the tumor grows, it can be divided into intratubular type, wall-invasive type, massive type, spherical type, nodular type and diffuse infiltrative type. According to histopathology, it can be mainly divided into small cell carcinoma, squamous cell carcinoma, adenocarcinoma, large cell carcinoma, adenosquamous carcinoma, carcinoid, etc.

For central lung cancer, a bronchoscopic biopsy is usually performed; for peripheral lung cancer, a percutaneous lung puncture biopsy is performed, and lung cancer can be finally confirmed.

In terms of treatment, a reasonable treatment plan is mainly selected based on the pathological type, clinical stage and the patient's physical condition. In particular, the chemotherapy regimen used for different pathological types of lung cancer is different, especially for small cell lung cancer.

How to prevent lung cancer?

1. Stay away from tobacco and refuse secondhand smoke;

2. Try to avoid going out in foggy and hazy weather. If you go out, be sure to wear a mask that can prevent PM2.5 and try to reduce the time you stay outside;

3. Advocate green decoration, choose environmentally friendly green decoration materials, and stay away from formaldehyde and radon gas;

4. Choose the right cooking oil, minimize contact with oil fumes, regularly maintain the range hood, keep the kitchen ventilated, and reduce grilling and frying at home;

5. Maintain a happy mood, be less sulky, and avoid psychological pollution and cancerous personality;

6. Get enough sleep, which can prevent diseases and enhance immunity;

7. Insist on outdoor exercise and walk more in green environment with good air circulation;

8. In terms of diet, eat more fruits, vegetables and drink more green tea;

9. Regular physical examinations, especially for various tumor markers, including chest CT scans. Even if you have lung cancer, you hope that through regular physical examinations and chest CT scans, you can detect and treat it in time to achieve clinical cure.
