Although there are various causes of headache, such as lack of sleep quality and catching a cold, if it is caused by this factor, it will get better after taking enough rest or taking medicine. However, if daily life is regular and there are no related symptoms, but recently you have a headache inexplicably, you have to be relatively careful whether cancer cells in your body are sweeping. At this time, don't simply think that you haven't had a good rest, and you can't take painkillers. The proper way is to go to the hospital for examination immediately.

2. The face turns black and swollen

As we all know, in physical and mental health, everyone's face will appear white and red, but once the skin color of the face turns black slowly, it may be that there are cancer cells in the body, especially in the mouth. This is because cancer cells continue to damage the liver, leading to a decrease in its metabolism, so that melanin will accumulate on the face. The primary cause of facial swelling is probably that lung cancer cells invade the superior vena cava, which leads to vein occlusion. Under such circumstances, blood night of the body and face cannot flow back normally, which leads to facial edema. If we don't attach great importance to it, cancer cells will continue to sweep, and they will compete with the body for nutrients, which will reduce the content of colloid osmotic pressure and its protein, thus aggravating the edema problem.

3. Bleeding

The bleeding mentioned here mainly includes the nasal cavity and the gum area. If there is no external harm, the unexplained bleeding in these two areas may be caused by early liver cancer. Because the coagulation factors of the body must be generated in the liver, if the liver becomes diseased, it will directly affect its routine function, reduce the total number of coagulation factors and cause coagulation disorders, and finally it is mainly manifested as inexplicable nosebleeds.

Second, how to improve? 1. Poor diet.

The study found that people who often eat kebabs, greasy and pickled ingredients are more likely to be confused by cancer. Because there is a large amount of phosphate in the pickled products, it will merge with the ammonia in the food in the stomach and become ammonium nitrite, which is a strong carcinogen. The fried barbecue ingredients will not only lead to weight gain, but also cause carcinogens such as benzene series in the process of making.

2. Smoking and drinking

Smoking is the main factor to promote cardiovascular diseases, lung cancer and other malignant diseases, and the reason depends on the harmful substances such as cigarette tar and nicotine in tobacco companies. At the same time, excessive drinking is closely related to early liver cancer. Because ethyl acetate is converted into acetaldehyde, such chemicals will cause cell canceration.
