Compared with lung cancer, liver cancer and other malignant tumors, skin cancer seems to be uncommon in daily life.

皮肤上长出地图形红斑?当心患上皮肤癌

  Common skin cancers include squamous cell carcinoma and basal cell carcinoma, both of which originate from the skin.


  The most aggressive malignant skin cancer is melanoma.


  It is worth noting that precancerous diseases associated with this type of malignant tumor often look similar to common skin inflammation or skin hyperplasia and are easily ignored.


  Therefore, the following knowledge must be kept in mind in the prevention and treatment of skin cancer.


  What are the characteristics of skin cancer?


1.The skin surface structure changes, but there is no special feeling


  Different types of skin cancer may have different appearances at the early stage of the disease, but the common feature is that there is basically no sense.


  If it is dermatitis, eczema or other skin diseases, the vast majority of patients will have itching, pain and other discomfort symptoms. In the case of skin cancer, most changes in the patient's skin will not bring this feeling, even if there is occasional itching, it is slight.


  2. Erythema edge is irregular


  In appearance, erythematous lesions caused by dermatitis and eczema have relatively regular shapes, such as round, oval or spindle.


  However, the erythema caused by skin cancer has irregular edges and similar shapes, which are different from normal erythema papules in appearance and shape.


  3. Traditional medical treatment does not work well


  For early lesions of skin cancer, conventional drugs for dermatitis and eczema are ineffective.


  If symptoms occur, the ointment does not improve, the area of local erythema continues to expand, the color of erythema is uneven, the shape is irregular, the surrounding capillaries expand, scabbing and scaling occur, but there is still no feeling.


  At this time, we should be vigilant, go to the hospital for inspection and diagnosis.


  4. Pigmented nevus appears problems in a short period of time and changes obviously


  If significant changes in the shape, color and size of the pigmented nevus are observed in a short time,


  For example, the originally round pigmented nevus becomes irregular within a few months,


  For example, the size suddenly increases, the color changes from uniform to different depths, and the surface is uneven or even damaged,

  Or there are satellite like small black spots around the original nevus. We need to go to the hospital for further diagnosis.


  If there is no obvious change in the appearance of nevus in 1 to 2 years or even more than 10 years, it is safe no matter what its size and shape are.


  For congenital pigmented nevus, the shape may be irregular at birth. If there is no obvious change in the above shape, color and size, but with the growth of age, with normal physical development, it is safe to expand or increase the bulge height in proportion.


  It should be noted that if there is no pigmented nevus, the overall development is relatively stable, but it grows in a position where children are prone to friction and constant stimulation,


  If the palms, soles of feet and armpits, or the degree of protrusion is high, which is easy to scratch and cause bleeding and scabbing, the risk of this kind of nevus is higher than that of common pigmented nevus, and you can go to the hospital for treatment.


  How to protect skin in daily life?


1.Do a good job in cleaning, moisturizing, sunscreen and other daily skin care.


  But pay attention not to over clean, otherwise it is easy to damage the cuticle and barrier of the skin, causing skin allergy.


  2. Make up water scientifically.


  The lack of water on the skin surface is not only a lack of water, but also a lack of oil.


  The sebum membrane that protects the skin needs to balance water and oil to prevent water from evaporating out.


  In spring, people often feel their skin dry, itchy and red, and like to carry sprays with them.


  However, the main component of the spray is water, which will damage the sebum film when used, making the water in the inner layer of the skin more volatile, resulting in the problem of the spray getting drier and drier.


  3. Develop the habit of "hard sun protection"


  The sunscreen needs to be used in large quantities to achieve the desired effect, but the use of sunscreen in large quantities will cause discomfort of stickiness, so the "hard" method can be used,


  For example, wear a hat and sunscreen when going out.


  In this way, even if the amount of sunscreen is not enough, the sunscreen effect can be guaranteed.
