Why are more and more people suffering from cancer? Most of them are related to bad habits.

 Due to the change in lifestyle, the incidence of cancer is increasing nowadays, and there is a trend towards younger people. Almost all cancers have a serious impact on health, and may take the life of the patient when they develop to an advanced stage.


Instead of being afraid of cancer, it is better to do prevention work. Therefore, it is important to understand the main causes of each kind of cancer so that we can do prevention work from the root.


What are the main causes of these 5 types of cancer?

1. The main cause of esophageal cancer is eating hot food

The maximum temperature tolerated by the oral cavity and esophagus is 60℃. If you eat food over 60℃ frequently, it will cause mild burns to the oral mucosa and esophageal mucosa, and if you eat hot food regularly, it will repeatedly hurt the oral mucosa and esophageal mucosa, so that the mucosa will be hurt again without repairing, and the mucosal cells will degenerate and proliferate over time, which may eventually induce cancer and increase the chance of esophageal cancer.

2. The main cause of lung cancer is smoking

The incidence of lung cancer is particularly high, ranking first among all malignant tumors. The incidence of lung cancer is very closely related to smoking, generally speaking, if you smoke 20 cigarettes a day and are more than 20 years old, the chance of developing lung cancer will increase more than 30 times, because there are more than 1000 kinds of harmful chemicals in tobacco, and the smoke produced by burning tobacco will directly adhere to the lungs, which will cause normal cells to become cancerous and increase the chance of lung cancer over time.


3. The main cause of stomach cancer is eating leftover food

Some people are so frugal that they will continue to eat leftover food once it is heated up, not knowing that such food, especially leftover food, contains a lot of nitrite, which is a strong carcinogenic substance and will increase the chance of occurrence of digestive tract cancer. In addition, eating pickled food often will also increase the chance of stomach cancer, because pickled food is rich in nitrate, which will produce nitrite after entering human body, and this substance is not only a first-class carcinogen, but also will cause repeated stimulation to gastric mucosa, which will eventually cause lesion to gastric mucosa cells.

4. The main cause of liver cancer is drinking

After alcohol enters the body, it is mainly metabolized by the liver. In the process of metabolism, it will not only produce a substance called acetaldehyde, but also produce oxidizing substances and free radicals, which are very difficult to remove and will bring toxicity to the body over a long period of time.

5. The main cause of breast cancer is staying up late

Breast cancer has a high incidence rate among female malignant tumors, and staying up late is the main factor that leads to breast cancer, because staying up late or lack of sleep will cause endocrine disruption, prompting the body to secrete a lot of estrogen, increasing the chance of breast cancer, so women should not only avoid staying up late, but also go to the hospital for regular breast examinations, and once the abnormality occurs, it should be solved in time.

 What saving behaviors can induce cancer?

1. Still eat moldy food

Food left for too long is easy to mold, many elderly people wash or remove the moldy part before eating. But even if the moldy part is removed, the other parts will have toxins and mold that cannot be seen by the naked eye. In particular, moldy food and nuts such as rice, peanuts, corn, pistachios and melon seeds, which contain aflatoxin, which is known to be a carcinogenic substance, long-term small dose intake of aflatoxin will also increase the risk of liver cancer. Therefore moldy food must be thrown away, there is a harsh taste of cooking oil can not be used, eat bitter nuts should be immediately spit out and light salt water gargle.


2. often eat leftovers

Too many bacteria proliferate in leftovers, but also a large number of nitrites, nitrites into the body can be combined with amines to generate a class of carcinogenic substances nitrosamines, eaten for a long time can increase the risk of stomach cancer. Therefore, when cooking, you must consider the number of people and the amount of meals, and try to eat less leftovers, especially overnight leafy greens and soups.


3. Edible oil used repeatedly

Cooking oil that has been fried contains polycyclic aromatic hydrocarbons in the residue, which can increase the risk of cancer when eaten for a long time; cooking oil that has been left for too long can produce epoxypropylene aldehyde after heating; cooking oil can produce fatty acid polymers after repeated high-temperature heating, which can increase the risk of liver cancer and esophageal cancer when used regularly. If you need to use cooking oil to fry food, you must filter the residue in the oil, pay attention to the color and smell of the oil has not changed, once the oil has changed should be immediately thrown away.

4. Do not open the hood

Long-term exposure to high-temperature fumes can increase the chance of lung cancer, especially when the oil is heated to 150℃, acrolein can be generated, which can stimulate the eyes, throat and nose, easily inducing bronchitis and rhinitis; when soybean oil or canola oil is heated to 270℃ or more, a large amount of oil condensate can be generated, and prolonged exposure can damage cell chromosomes, thus inducing cancer. Long-term exposure to oil smoke, PM2.5 and carcinogenic substances can be adsorbed in the alveolar wall, damaging cell DNA and increasing the chances of lung cancer. So before cooking food, you must open the hood and windows, and wear a mask if necessary to avoid inhaling particles; after cooking food, open the hood for at least 10 minutes to ensure that all harmful gases are discharged.

5. save not to see the dentist

Many elderly people will buy their own painkillers for tooth pain in order to save money, which makes oral problems more and more serious and increases the risk of oral cancer due to repeated stimulation of oral mucosa. Therefore, once oral problems occur, it is necessary to consult a dentist early to remove the remaining roots and crowns and grind off sharp teeth. If the mouth ulcers do not improve after two weeks, you need to consult a doctor as soon as possible.

Warm Tips

In order to reduce the chance of various cancers, in addition to improving one's own physical quality, one should also develop good living habits, such as eating warm food frequently, quitting smoking and drinking in time, not eating leftover food, not staying up late, etc. It is recommended to ensure sufficient sleep time, not only 7~8 hours every night, but also take an hour for lunch break at noon.

Having more than 30 minutes of moderate intensity aerobic exercise, such as brisk walking, jogging or rope skipping, 4-5 times a week can improve resistance and reduce the risk of many types of cancer; pay attention to a balanced diet and eat less pickled and smoked foods and processed meat products; refuse to smoke and drink alcohol to avoid exposure to cancer-causing and cancer-promoting agents; people with high risk of cancer should go to hospitals regularly for cancer screening.

Why is Alzheimer's increasing? If these 5 bad habits are not changed, they will become the burden of children!

Image
 Alzheimer's disease is a disease that many elderly people can't avoid, and this disease will add a great burden to their families once they suffer from it. In fact, more and more people are suffering from this disease because of some bad habits in daily life. Why Alzheimer's is increasing The main cause of Alzheimer's disease is still caused by aging, especially after the age of 65. This mutation occurs mainly in older people, and the older they are, the higher the rate of the disease will be. Another reason is heredity. If an immediate family member suffers from this disease, the probability of the offspring suffering from this disease will be much higher than the general population. In addition, people with cardiovascular disease are also at increased risk of developing Alzheimer's disease. There are many blood vessels in the brain that supply brain tissue with nutrients, and cardiovascular disease increases the probability of stroke, which in turn increases the ...
