"The itch on grandma is actually caused by tumor," said the doctor. Because pancreatic cancer causes jaundice, jaundice stimulates the skin, leading to itching of the skin.
Unfortunately, because Wang Apo did not see a doctor in time, the condition at this time could not be operated, and even chemotherapy and radiotherapy could hardly benefit from it.
Seeing this, did you stop scratching your hands immediately? Itching seems to be a minor illness, but it can also hide a big disaster.
First, the five major causes of itching
Itching is not a disease. Itching is really terrible. Itching is a skin feeling. On the surface, the skin is often not damaged or not obvious, but it will make people very uncomfortable, and this feeling can last for several minutes or even hours. If you really put up with it, I'm afraid it will make people upset. In fact, any abnormality in the body is a signal, and itching also has a reason.
1, simple skin problem
The skin itself lacks moisture, or the skin degenerates with age and the water content decreases. These conditions easily lead to dry skin and make intradermal nerve endings more susceptible to stimulation and itching. In addition, if there are skin diseases, such as eczema, dermatitis and psoriasis, skin itching may also occur.
2. disgust
Professor Liu Guanghui, chief physician of Wuhan tongji hospital Allergy Department affiliated to Tongji Medical College, Huazhong University of Science and Technology, said that clinically, 1/3 of allergic patients he met were accompanied by itching symptoms. For example, itching caused by allergic reactions to pollen, seafood and certain chemicals can generally be relieved by staying away from the original allergy.
3. Hepatobiliary diseases
According to statistics, about 40%-60% patients with hepatobiliary diseases will have itching symptoms. For example, when the biliary tract is blocked, bile salts are deposited on the skin. If nerve endings are stimulated, it may make patients itch unbearable and produce intractable skin itching.
4. mental illness
Mental factors may also cause skin abnormalities, such as parasitic paranoia. Patients always think that they have parasites and feel that the skin has the feeling of ants crawling, so they constantly scratch the skin.
5. Malignant tumor
Some tumors can cause skin itching, just like the itching caused by Huang Ayi's liver cancer, and the itching caused by malignant tumors. Most of them are stubborn and need special attention.
Second, we should be especially alert to itching caused by malignant tumors.
There are many reasons for skin itching, and the terrible ones are some primary diseases, especially life-threatening diseases such as tumors. Be wary of itching caused by malignant tumors.
1. Where does the itch of cancer come from?
Itching receptors are distributed in the skin in the form of dots. When nerve endings or unmyelinated neural networks on the surface of the skin are stimulated, these receptors will trigger signals, which will be transmitted to the brain to produce itching. Generally speaking, the more sensitive the human body is, the easier it is to itch, and some types of visceral tumors in the human body will secrete special factors, such as inflammatory factors and itching mediators, which will cause itching when stimulated. It is clearly recorded in the literature that itching is closely related to malignant tumors, and visceral tumors are found in 3% ~ 47% of patients with systemic itching.
Studies have shown that itching and tumor sites are often very close, unless the tumor symptoms are obvious and have developed to the systemic stage. This may occur in cancers involving the lymphatic system, stomach, intestine, liver, ovary, prostate and other organs. According to the data investigation, 16~30% of the elderly patients with lymphoma, 25% of the patients with reproductive organ malignant tumor and 50% of the patients with rectal malignant tumor all have skin pruritus symptoms in different degrees.
2. What are the characteristics of cancer itching?
Since there are various reasons for itching, what are the characteristics of itching caused by tumors? Itching caused by malignant tumor probably has three characteristics: first, chronic intractable itching; Second, there are no special factors, such as skin diseases, and the cause cannot be seen from the surface; Third, the commonly used antipruritic drugs all failed.
Third, the itching is uncomfortable, remember not to scratch.
Itching is one of the most unbearable feelings for human beings. As soon as I feel itchy, many people will involuntarily make a "scratch" action. As everyone knows, the more you scratch, the worse you feel. As mentioned above, itching is a feeling, which is that the receptors on the skin surface receive external stimuli and then transmit signals to the brain. This signal transmission process needs media, and conversely, once the media is produced, it makes people feel itchy. When scratching, the skin will often be scratched, which will enlarge the damage or stimulation around the receptor, thus increasing the production of media and itching.
The correct way to tickle is to put your five fingers together and quickly get up and down the itchy part. If not, you can apply it with cold water or ice. At the same time, it is best to open and ventilate the surrounding environment, and wear loose clothes. If dermatosis can be observed, some antipruritic drugs can be used appropriately, otherwise it is necessary to consider whether it is itching caused by tumor, seek medical advice in time and investigate the cause.
Itching, a small symptom, is often overlooked in people's lives, but it hides such an important health password. It seems that people should pay attention to the supplement of living habits and medical common sense in life, so as to be prepared and treat the signals sent by the body correctly when necessary. # Scientific Truth # # Breeze Project #
