There is a disease in the body, but the hands and feet know it? There are 4 abnormalities in the limbs, beware of lung cancer knocking on the door

Winter is coming, many people will grow "radish hands" because of frostbite, but the special "radish hands" may also be caused by cancer!

According to Guangming.com, in the past six months, Ms. Jiang from Shenzhen did not know why her ten fingers had become thicker and swollen badly, and her legs were also a little painful. No matter how much she took medicine, she didn't get better.

Unfortunately, Ms. Jiang is an intermediary and has just received a thoracic surgeon from the Cancer Hospital. When the doctor saw her finger was swollen like a turnip, she felt abnormal. He advised her to go to the hospital for an examination as soon as possible. It might be something wrong with her lungs.

The doctor did not expect the examination results. CT suggested that there was a 5 cm tumor in Ms. Jiang's lung, which was lung cancer and was already in the middle stage. The doctor said that more will be found at night, the consequences will be unimaginable, and it can be surgically removed now.

Just because of a swollen finger. The doctor made an accurate diagnosis of the manifestation of the pain in the leg, which really makes people have to accept it. Some people always think that headaches and leg pains can treat the legs. In fact, lung cancer can be said to be a systemic disease. Symptoms are not limited to the lungs and may cause abnormalities in the extremities. Today, Xiaoai will give you a good summary.

1. There are four abnormalities in hands and feet, do not ignore them

2. Swollen fingers

The end of the finger is swollen like a small drumstick, which is also called "clubbing" in medicine, which is a disease reflected on the finger. According to Zhu Hui, Chief Physician of the Thoracic Surgery Department of the First Affiliated Hospital of Nanjing Medical University, generally speaking, clubbing is more closely related to heart and lung diseases, such as congenital heart disease, emphysema, and chronic bronchitis.

A small number of lung cancer patients will have symptoms of finger clubbing, usually because lung cancer cells secrete some hormones into the blood, resulting in paraneoplastic syndrome and finger swelling. After tumor resection, symptoms of clubbing fingers disappeared.

2. Inexplicable pain

Dr. Zhang Yalei, deputy director of the Thoracic Oncology Department of the First Affiliated Hospital of Guangzhou Medical University, said that there are many causes of joint pain, including various tumors, one is leukemia and other blood system tumors, the other is multiple myeloma, and the third is Advanced cancer with multiple bone metastases, which is common in advanced stages such as lung cancer.

In addition, joint pain caused by lung cancer is often manifested in the knee joints. Wrist joints and other large joints are grown from lung squamous cells. Hormones secreted during differentiation stimulate joint hyperplasia.

3. Severe upper limb pain

Many people are unaware that lung cancer can also cause severe upper extremity pain. Usually, this severe pain is caused by swelling and pinched nerves from the apex of the lung. In addition, lung cancer may also compress the sympathetic plexus in the neck, causing drooping eyelids, miosis, and sunken eyeballs.

4. Weakness in hands and feet

If you often feel weak in your hands and feet while doing nothing, don't simply think it's just physical fatigue. You may want to consider whether you have polymyositis. Symptoms of polymyositis are usually loss of appetite, general weakness, and even inability to walk in severe cases. Bedridden. About 85% of cases of polymyositis are symptoms that precede the typical symptoms of lung cancer.

It is worth noting that abnormal hands and feet are not necessarily caused by lung cancer. Typical symptoms of lung cancer, such as cough, hemoptysis, chest pain, and physical discomfort, must seek medical treatment in time without delay.

2. Why is lung cancer more and more common?

In the past 30 years, the incidence of lung cancer in China has increased by more than 400%, which is not terrible. In 2020, according to statistics from the International Agency for Research on Cancer of the World Health Organization, there will be about 4.57 million new cancer cases in China, including about 820,000 lung cancer cases, accounting for more than one-sixth.

Why is the incidence of lung cancer rising in China? According to Professor Zhi Xiuyi, director of the Lung Cancer Diagnosis and Treatment Center of Capital Medical University, the following reasons are crucial.

1. The average life expectancy is getting longer

With the continuous improvement of material level and the extension of average life expectancy, the phenomenon of population aging will inevitably appear. The aging population makes various chronic lifestyle diseases more prone to occur, which will not only increase the incidence of lung cancer, but also increase the incidence of other chronic diseases, such as malignant tumors or cardiovascular and cerebrovascular diseases.

2. There are more and more smokers

Smoking is the leading cause of lung cancer, responsible for more than two-thirds of lung cancer deaths worldwide. Tobacco contains hundreds of harmful substances, and 69 kinds of carcinogens have been identified. At present, there are 316 million smokers in China, and the number of people exposed to second-hand smoke is as high as 740 million.

Even if you don't smoke, prolonged exposure to secondhand smoke at home or at work can increase your risk of lung cancer. If you do not control second-hand smoke exposure. Reduce smokers, tobacco-related diseases such as lung cancer will inevitably rise.

3. Deterioration of atmospheric environment

In addition to smoking, the deterioration of the atmospheric environment is also an important reason for the rising incidence of lung cancer in China. With the development of industrialization, the natural environment is no longer as pure as before. Water pollution, air pollution, land pollution and other pollution emerge in an endless stream, which not only destroys the environment, leads to the deterioration of the atmospheric environment, but also leads to the occurrence of cancer.

4. Indoor air pollution

In addition to external environmental pollution, indoor air pollution may also cause cancer. With the development of the home decoration industry, various decorative materials are widely used in decoration, many of which will volatilize aromatic hydrocarbons. If the concentration is too high, organic compounds such as aldehydes will cause harm to human health.

In addition, if you like to use frying, cooking methods that use a lot of oil, such as frying oil without installing ventilation facilities in the kitchen, will also cause kitchen fume pollution, thereby increasing the risk of lung cancer.

3. Over the age of 50, you must arrange a chest CT for yourself

How should lung cancer be prevented? The high incidence of lung cancer after the age of 50 can be effectively detected by chest CT screening for early lung cancer, and the mortality rate of lung cancer can be reduced by 20%.

Professor Yi suggested that if you are over 50 years old and you have never had a chest CT scan, you can arrange a chest CT scan for yourself. Low-dose chest CT is more accurate than X-ray, and the radiation dose is smaller than that of general good CT. It is the best choice for screening lung cancer.

It turns out that in addition to hemoptysis, typical symptoms of lung cancer, such as chest pain, may also be reflected in the limbs. Joint pain and other symptoms cannot be ignored. In everyday life, you cannot be careless about abnormalities in your body. You should see a doctor in time when conditions permit to protect your health
