Not a skin disease, but a cancer warning? 4 kinds of abnormal skin appear, beware of cancer coming
The hashtag #Dying went viral last year when US social "influencer" Pearson was dying. Unlike the painting style that conveys happiness, happiness and beauty, every video she sends is labeled "dying".
It turns out that Pearson is a patient with advanced skin cancer. When she was 18 years old, she found a mole on her skin, and this mole was different from ordinary black moles. The shape, color, and size revealed strange, and very Dry, itchy, and occasionally bleeding ...
There were indications that the mole might be a melanoma, but Pearson knew nothing about it at the time.
This delay was 3 years. When she was 21 years old, the doctor told her that it was melanoma, which had developed to stage 3 and spread to the lymph nodes. The survival rate was only 66% .
At the doctor's advice, she underwent surgery, but her condition continued to deteriorate to stage 4 and even spread to the lungs. At the beginning of last year, the doctor regretfully informed Pearson that the melanoma had spread to her body and entered her brain. From a medical point of view, no further surgical intervention is recommended...
In order to record the last time, Pearson began to use video to record life, and reminded everyone to pay attention to check the small conditions on the skin at any time, and called on everyone to check the sooner the better.
1. The more moles people live, the longer they live?
The number of moles is linked to telomeres at the ends of chromosomes, and longer telomeres are associated with longer lifespan, a study from King's College London found. "
However, according to research, this statement is completely nonsense. After searching many well-known databases, no relevant information was found, and no references were marked in the original text. It can be said that the "research" is likely to be fabricated.
At present, the medical community does not have a clear explanation for the reasons for the differences in moles on each person, the function of moles, and there is no evidence that the number of moles is related to longevity .
Professor Harald Kittler of Austria stated in his lecture "Typical and Atypical Moles" that about 25%-33% of skin melanomas are caused by moles , where moles refer to atypical moles (ie, dysplastic moles).
In particular, moles in these parts of the body increase the risk of malignant transformation——
Parts of the body that are easy to rub : palms, soles of feet, armpits and other parts that are easily rubbed by the outside world;
Under the nail/toenail : transverse melanoma mostly grows in these parts;
On mucous membranes : such as eyes, lips, mouth, esophagus, anus, genitals, etc.;
Long-term exposure to sunlight : face, neck, back, calves, etc.
If there are moles on the above body parts , accompanied by asymmetrical shape, irregular edges, different shades of color, obvious changes in the size and shape of moles, or even itching and ulceration, it should be highly regarded, it is likely to be skin melanin caused by tumor.
2. Abnormal skin is not necessarily a skin disease, be alert to the advent of cancer
Skin changes are very common. When mosquito bites or allergies, the skin will itch; when basking in the sun, the skin will be tanned if the sunscreen is not in place; if you hold heavy objects in your hands and compress the blood vessels, the palms will turn red... But if the skin appears Changes, and long-term unrelieved, we must be alert to the possibility of the following types of cancer:
1. Itchy skin
- cervical cancer
Frequent skin itching, accompanied by abnormal menstruation and vaginal secretions , should be alert to the possibility of cervical cancer. This is caused by tumor cells secreting some abnormal substances, causing skin changes, which in turn causes itching.
- Pancreatic cancer
Skin pruritus is a common symptom in patients with pancreatic head tumors. The lesions of the pancreatic head cause biliary obstruction and bile salt accumulation, thereby causing skin pruritus.
- lymphoma
As the disease worsens, lymphoma patients will be accompanied by generalized skin pruritus, swollen lymph nodes, fever, weight loss and other symptoms.
2. Yellowing of the skin
For Asians, most people have yellowish skin, but if the skin turns yellow abnormally and the whites of the eyes turn yellow , it is important to be alert to liver problems, especially liver cancer.
When the liver is damaged, the ability to secrete bilirubin will be reduced, resulting in the inability of the body to excrete bilirubin in time, and the reverse flow of blood will cause jaundice.
3. Skin flushing
Redness of the skin is likely to be a sign of cancer. For malignant tumors of the lymphoreticular endothelial system, such as lung cancer, stomach cancer, prostate cancer, etc. , about 8% to 20% of patients will experience reddened skin, which is manifested as whole body skin flushing , swelling, desquamation.
4. Purple dots appear
Purple spots appear on a large area of the skin, which is manifested as purpura, which is likely to be abnormal platelets caused by lymphoma, myeloma, leukemia, etc. When the number of platelets decreases sharply, purpura is prone to occur.
3. The 4 major "murderers" are accelerating skin aging, how to prevent it?
Skin is one of the most intuitive manifestations of human aging. When a person gets older, fine lines, spots, and senile warts will appear on the skin. But in fact, in addition to physiological effects, these factors that accelerate aging, if you do not pay attention to prevention, are likely to accelerate the "aging" of the skin.
In particular, sun exposure, staying up late, improper skin care, and smoking will further accelerate skin aging.
With the arrival of summer , affected by the environment and sunlight, we should pay more attention to the maintenance of our skin.
1. Indoor moisturizing
Blowing the air conditioner for a long time will draw the "moisture" from the skin, and as the moisture is lost, the skin will be tight, itchy, and the skin barrier will be damaged.
Therefore, in the air-conditioned room, you must pay attention to skin moisturizing. Lotion and moisturizing cream should be carried with you and used frequently. At the same time, drink plenty of water, not only the outer layer of the skin should be hydrated, but also the body should be hydrated in time.
2. Outdoor sun protection
In summer, the ultraviolet rays are strong, and sun protection is also very important when going out. Sunscreen products should be used half an hour before going out, and should be reapplied every 2 to 3 hours outdoors to ensure the sunscreen effect.
The skin is a "barometer" of health, especially for some major diseases, "signatures" can be found through the skin, and early intervention can greatly control the disease in the early stage.
Therefore, don't ignore your skin health, if there is an abnormality, it is recommended to go to a dermatologist to check whether it is caused by disease or cancer.
