After reading the 10 rumors that doctors in various disciplines want to clarify most, they can spend less money.

When some people go to the hospital to see a doctor, they always say, "I saw it on the Internet …" "I said it on the Internet …" In this regard, many doctors are really helpless. As the saying goes, "rumors are rumored and rumors are broken." Don’t believe these rumors!

This medicine can soften or dissolve bone spurs!

Zhan Hongsheng, Director of Orthopedic Department of Shuguang Hospital affiliated to Shanghai University of Traditional Chinese Medicine:

Sometimes I see some advertisements, saying that a certain ointment can soften or even dissolve the bone spur if it is applied to the body surface, absorbed or eaten. This is actually a typical false propaganda.

Spur is some seemingly extra bones growing on the surface of bone, which is basically consistent with the composition and structure of normal bones. Imagine that if this medicine can soften or dissolve the spur with a touch or a bite, then the normal bones connected with the spur will also be softened and dissolved together, so that people will not fall apart?

Small lung nodule = small lung cancer?

Han Dingpei, Attending Physician of Thoracic Surgery, Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine:

In order to attract everyone’s attention, some people on the internet directly refer to "small pulmonary nodules" as "small lung cancer", which is incorrect and a bit alarmist.

Because it is impossible to make pathological diagnosis (gold standard) only by CT film, the diagnosis made according to CT film is based on the doctor’s experience and the statistical analysis of previous cases, and gives a probability or tendency conclusion.

Among the small pulmonary nodules shown in CT films, lung cancer only accounts for a part, others may be benign diseases such as inflammation, tuberculosis and lymph node hyperplasia, and even some are normal vascular shadows in the lungs. Please see the following figure.

I have no symptoms, so I can’t have diabetes?

Su Qing, Director of Endocrinology Department, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine:

Many people will ask, how can I get diabetes without the symptoms of dry mouth, excessive drinking and excessive urination?

In fact, this is a misunderstanding. Many diabetics (especially type 2 diabetes) do not have the above symptoms. At present, many people find that blood sugar is slightly elevated in physical examination, and they don’t feel much, so they can’t diagnose diabetes by whether there are symptoms or not. Regular examination is very important.

Health care products are said to lower blood pressure. Can you eat them?

Yang Ruiling, Deputy Chief Physician, Department of General Medicine, Affiliated Hospital of Xuzhou Medical University:

In recent years, there are many kinds of health care products that claim to have antihypertensive effect on the market, such as antihypertensive pillows, antihypertensive watches, antihypertensive caps and antihypertensive insoles. Is this really the case?

In fact, the antihypertensive efficacy of health care products has not been scientifically clinically certified at all. Blind application of health care products to reduce blood pressure, even if the health care products themselves are harmless, will easily delay the treatment of diseases. Some health care products have a good effect on lowering blood pressure, but they are actually very simple, and there are "western medicines" in them.

Drink more soy milk, have big breasts and wear rims underwear, all of which are easy to get breast cancer?

Chen Xin, Deputy Chief Physician of Breast Surgery, Obstetrics and Gynecology Hospital Affiliated to Zhejiang University:

Phytoestrogen ≠ Estrogen, the cause of breast cancer is human estrogen, not phytoestrogen. Soybean isoflavones have a two-way regulating effect, which can help the human body to stabilize and regulate estrogen, so soybean milk can be safely drunk.

The risk of breast cancer has nothing to do with breast size. Because no matter the size of the breast, the structure and number of ducts and glands in the breast are basically the same, and the size of the breast depends more on the fat content.

The occurrence of breast cancer is not directly related to the type of bra worn and the time when the bra was first worn. It should be noted that if the steel ring bra is not properly worn and tightened too tightly, symptoms such as skin allergy may occur.

Dysmenorrhea is palace cold, need to do conditioning?

Zhou Xiaoli, Attending Physician of Obstetrics and Gynecology, Punan Hospital, Pudong New Area, Shanghai:

Palace cold is a good excuse to fool people: infertility? Gong Han! Menstruation? Gong Han! Less menstruation? Gong Han! Is there a blood clot in menstruation? Still palace cold!

I’ll scare you to death first, and then I’ll sell you a care package for women and a box of so-and-so palace cold stickers.

The front, back, left and right sides of the uterus are protected by various organ fats. The blood flowing through the uterus flows from the heart and flows back to the heart. It is basically constant temperature, and it will not get cold when it reaches the uterus. If it is cold, it must be cold all over …

Some people say that there is something wrong with eating cold food. To be honest, it is a little cold, and it is almost the same as the body temperature in the stomach, and it is in the digestive tract. What does it have to do with the uterus? Even if your hands and feet are cold, it has nothing to do with the uterus.

If you are sick, you need regular treatment. If you are not sick, don’t be superstitious about conditioning. Otherwise, it’s not cost-effective to pay IQ tax and fix more problems.

Fatty liver is neither painful nor itchy, leave it alone!

Jiang Weimin, Chief Physician, Department of Infectious Diseases, Huashan Hospital, Fudan University:

Theoretically, after removing the cause of simple fatty liver, the liver can completely return to normal. However, fatty liver itself can develop. Once it develops into cirrhosis, even if it is actively treated, it is impossible for the diseased liver to return to normal.

Therefore, after we find that we have fatty liver, we must treat it as soon as possible. If fatty liver is not found in time or is not taken seriously by physical examination, it will develop. When there is pain in the liver area, nausea and vomiting, fatty liver has developed to a very serious degree, which may lead to cirrhosis, liver cancer, hypertension, hyperlipidemia and other diseases in the future.

Stomach upset? Just drink porridge for a few days!

Zhang Zheyong, Deputy Chief Physician, Department of Gastroenterology, Ninth People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine:

At least eight of the ten Chinese people have heard of the theory of porridge nourishing the stomach.

Contrary to everyone’s impression, although eating porridge feels easy to digest, it is easy to cause or aggravate the symptoms of gastroesophageal reflux. This is because the composition of porridge is mainly carbohydrates, and a large amount of carbohydrate intake will lead to the decrease of sphincter tension in the lower esophagus, while the emptying time of porridge in the stomach is short, and the effect of neutralizing gastric acid will be significantly reduced, which may lead to acid reflux and heartburn.

In addition, the nutritional components of porridge are single, and the protein content is low, so long-term eating will lead to malnutrition, so even normal people are not recommended to eat porridge frequently.

Dye your hair, it causes cancer!

Dr. Zhou Jianping, Department of Respiratory and Critical Care Medicine, Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine:

It is scientifically proved that dyeing hair does not cause cancer in most cases. If you dye your hair, it is best to use permanent hair dye no more than twice a year, and wash your hair often after dyeing; People with allergic diseases, pregnant women, lactating women and children should try not to dye their hair; Allergy test should be carried out before dyeing hair; Be sure to use qualified hair dyes; Confirm that the hair dye used is produced by a regular manufacturer.

Bone soup can supplement calcium!

Chen Jie, Attending Physician of Orthopaedics, Huashan Hospital affiliated to Fudan University:

There is an old saying: "What you lack, what you eat." Many osteoporosis patients think that bone soup is the first choice for calcium supplementation. In fact, the calcium content in milk is much higher than bone soup. For the elderly, bone soup dissolves a lot of fat in bones, which may cause other health problems if eaten frequently.

To prevent osteoporosis, we should pay attention to the diversification of diet, eat less greasy and fatty foods, pay attention to some foods rich in calcium, insist on drinking milk, and avoid excessive intake of protein and caffeine.
