Li Laohan felt that his body was always itchy, at first he thought that the skin was dry in winter, but when he came over, he found that the location of the itch often changed, sometimes it was the front chest, sometimes it was the back, sometimes it was the thigh... It went on for several days and didn't get better. Li Laohan suspected that it was a skin disease, but there was no result after seeing the dermatology department. Finally, the doctor advised him to check his pancreas.
Although Li Laohan was confused, he also went to the pancreatic department to register. How do you know, after examination, it was diagnosed as pancreatic head cancer (a type of pancreatic cancer). Li Laohan was stunned, obviously just ordinary skin itching? How did it become cancer?
Skin itching is more common in patients with pancreatic head tumors, because pancreatic head tumors can cause biliary obstruction, causing cholestasis, which can cause skin itching.
1. Itching may also be a warning of cancer?
Itching is closely related to visceral malignancy, which is related to the fact that some tumors secrete some inflammatory factors, itching mediators, etc.
Wang Junhui, attending physician of the Department of Dermatology, Guang'anmen Hospital, China Academy of Chinese Medical Sciences, pointed out that there are many causes of itching, and the epidemiological reports of itching in systemic diseases vary from country to country, and about 10%-50% of patients can have systemic diseases of potential etiology, including diabetes, thyroid disease, kidney disease, anemia or tumor. It should be noted that solid tumors have a low incidence of skin itching, but the incidence in some blood tumors and lymphomas can be as high as 50% to 100%.
In general, the site of itching caused by cancer is mostly the site of tumor growth, but if the tumor is more malignant, systemic itching symptoms may also occur. When itching occurs acutely, there is no superficial change, there is no rash on the skin, and the use of antipruritic drugs cannot be relieved.
Second, there is stubborn itching in these parts, which is worth vigilance
Ordinary skin itching often has precipitating factors, while malignant tumor itching is more stubborn, especially when itching occurs in the following parts, pay special attention.
1. Itching with irregular position of the whole body
Ordinary itching, itching sites are generally limited to the damaged skin and surroundings, and the itching caused by tumors is not fixed because the active substance is dispersed with the blood to various parts of the body, stimulating the ends of the fibers, so the location of the itching is not fixed, and may spread throughout the body.
2. Itching around the mole
The nevi here may be melanoma, and early symptoms of melanoma include itching sensations in the surrounding skin.
3. Perianal itching
May be seen in patients with rectal cancer, where the tumor grows at the lower end of the rectum near the anus, irritating the anus and may cause abnormal defecation. If secretions from the intestine flow out of the anus, it can cause itching in the anus.
4. Itching of the vulva
Many people will take it for granted that vulvar itching is "vaginitis", in fact, there are many reasons for vulvar itching, including infection with trichomoniasis, fungi and other pathogenic bacteria; or vulvar diseases such as vulvar eczema, eczema, vulvar ringworm; or diabetes, allergic reactions, etc. will cause vulvar itching, of course, including the external vagina, manifested as vulva local ulcer surface, erosion, bleeding.
Of course, no matter which parts of the itch must be caused by cancer, there is an inexplicable and wonderful stubborn itching, it is best to go to the hospital in time to find out the cause.
Third, ordinary itching, how should it be solved?
The skin itches and makes people scratch madly, and if you scratch too hard, it may also cause skin damage, further irritate nerve fibers, and cause more intense itching. When encountering ordinary itching, how can you avoid scratching more and more itchy?
1. Mosquito bites
After being bitten by a mosquito, the body's immunity releases histamine, which causes itching. To stop the itch, it is best to apply cold compresses with an ice pack or apply an antipruritic ointment.
2. The skin is too dry
Dry and cracked cuticles of the skin will bring itching, for itching caused by the skin, it is recommended not to use too hot water when showering; wipe the moisture after bathing, and immediately lock in the skin moisture with moisturizer.
3. Sunburn
Sunburn can also accelerate the inflammatory response, leading to itching. The skin is red, swollen and warm, which can be relieved by applying cold compresses or applying aloe vera gel.
4. Wound healing
Itching occurs when the wound is about to heal, which is an inflammatory reaction. At this time, you can cool the skin by applying menthol to achieve antipruritic purposes.
5. Itching of the scalp
Human hair is susceptible to irritation by Malassezia, causing skin cells to grow, which can cause dandruff itching. It is recommended that people with dander problems can use shampoos that contain zinc pyrithione, salicylic acid, selenium dioxide, ketoconazole and other shampoos that can inhibit fungi.
6. Hemorrhoids itching
Weight gain, defecation, pregnancy, etc. will make the hemorrhoids become swollen, itchy, hemorrhoids itching and itching in addition to hemorrhoid ointment, can also be used with ice pack cold compresses or warm water sitz bath to alleviate the effect.

When itching occurs, it is necessary to first find out the cause of itching, if the cause cannot be found, and the use of antipruritic ointment can not be relieved, it is necessary to be vigilant and suspect whether the disease is caused. #谣零零计划 #
