Lung cancer is coming, leg prophet? Reminder: There are 2 abnormalities in both legs, it is recommended to check CT as soon as possible

Ms. Zhang is 42 years old this year. Compared with her peers, she is very self-disciplined. She does not smoke or drink, and she exercises every day. Her physical fitness looks good.

Six months ago, Ms. Zhang suffered from swelling and pain in her legs. She thought it was caused by improper exercise, but the plaster did not improve for a long time.

I had no choice but to go to the hospital for an examination accompanied by my lover, and it turned out to be lung cancer! Ms. Zhang couldn't figure it out, how could she be targeted by lung cancer even though she didn't drink or smoke?

1. Why do some people get lung cancer even if they don’t smoke or drink?

According to data released by the International Agency for Research on Cancer, 1.8 million people worldwide will die of lung cancer in 2020, ranking first in the number of cancer-causing people. Although smoking is a major risk factor for lung cancer, there are not a few people who do not smoke or drink are targeted by lung cancer.

The occurrence of lung cancer is related to many factors, such as genetics, kitchen fume, occupational exposure, passive smoking, etc., may increase the risk of lung cancer, which is why some people who do not smoke and drink will be targeted by lung cancer.

According to the international magazine "Lung Cancer", cooking fumes in the kitchen will increase the risk of lung cancer in non-smoker women by 3.79 times.

2. The coming of lung cancer, the leg prophet? 2 Anomalies Don't Ignore

According to statistics, when 70%-80% of lung cancer patients go to see a doctor due to obvious symptoms, most of them have reached the middle and late stages. Why is lung cancer in the middle and late stages when it is discovered?

Symptoms caused by lung cancer are generally caused by tumor growth, oppression or invasion, and the lung volume is relatively large, so the symptoms of early lung cancer oppression are not obvious, and it is difficult to attract people's attention.

When the tumor grows to a certain extent and obviously compresses the lungs, trachea and other parts, symptoms such as chest tightness, cough, shortness of breath, and dyspnea will appear .

After the onset of lung cancer, the legs may also issue an early warning, and the following abnormalities appear on the legs, which must be paid attention to.

1. Leg pain

Leg pain can easily be misdiagnosed as a joint problem, but lung cancer can also cause leg pain. This is because as the lung cancer cells grow, the cancer cells may invade the bones and even cause pulling pain or reflex pain in the legs.

2. Abnormal skin of the legs

After the lung function is abnormal, the breathing ability will be weakened, the oxygen content in the blood will be reduced, and the oxygen cannot be provided to the skin and mucous membrane tissue, which may cause the skin to become lighter.

Therefore, if the long-term smokers have skin abnormalities on the legs, it is best to perform low-dose spiral CT examination as soon as possible.

In addition to some abnormal symptoms in the legs, most patients with lung cancer will have some common symptoms such as cough, bloody sputum, hoarseness, chest tightness and shortness of breath. It is recommended that high-risk groups of lung cancer and those who have these symptoms should go to Hospital screening.

3. These people are high-risk groups of lung cancer, early prevention

Instead of waiting until the diagnosis of lung cancer before treatment, it is better to do a good job of prevention early, especially for high-risk groups of lung cancer, it is even more important to do a good job of regular screening.

People aged 50-74 who have smoked for more than 30 pack-years or suffer from COPD, or have a history of occupational exposure for more than one year, or who have been passively smoked for more than 20 years are all high-risk groups for lung cancer. Whether it is a high-risk group or an ordinary person, it is necessary to do a good job in the prevention of lung cancer.

• Quit smoking as soon as possible and stay away from the environment of second-hand smoke;
• Avoid indoor and outdoor air pollution, and turn on the range hood when cooking;
• Strengthen occupational protection measures to reduce occupational exposure;
• Regular medical screening.

High-risk groups of lung cancer, or those with related lung cancer symptoms, are recommended to undergo regular low-dose spiral CT screening. Early detection and early treatment can also greatly improve the survival rate and cure rate of patients.

Don't think that if you don't smoke or drink, you won't be targeted by lung cancer. After all, the occurrence of lung cancer is related to many factors. In view of the fact that the early symptoms of lung cancer are not obvious, many patients are in the middle and advanced stages as soon as they are diagnosed. Usually, the symptoms of lung cancer must be recognized, not only to prevent lung cancer, but also to carry out regular screening.
