A total of all the symptoms of skin cancer is changing, it is important to note everyone. Basal cell carcinoma and squamous cell carcinoma of the initial surface roughness may be some small patches of skin around a little more than a little red or white; it may be a small lump or a very easy bleeding, slow healing or healing of small ulcers. Start cancer may be very small, such as needle size, if left untreated, cancer cells will spread to the surrounding tissue; once the cancer has spread, treatment is more difficult and easier to leave a scar. Sunburn skin by the sun appeared occasionally with flat reddish patches, known as actinic keratosis, the disease is not cancer, but may become cancer. Malignant melanoma is the most dangerous form of skin cancer, symptoms usually appear stain the skin, change the color of moles, new moles, lesions involving the resulting black-brown pigment and pigment cells. Should pay special attention to dark skin spots, or changes in moles, new moles alert the formation of mole bleeding, dark spots of old and new changes in the shape and color, if found out that the symptoms of any kind should immediately seek medical treatment, do not delay . Early treatment, malignant melanoma often can be cured; ignored the cancer will spread to other parts of the body may attack the vital organs.

 

(1) chemical carcinogen
     Since the first description of Percivall chimney sweep made the workers reported that scrotal skin cancer after 100 years or so, it is found that frequent contact with arsenic, tar and asphalt workers prone to skin cancer.

(2) ultraviolet radiation
     1928 Findlay First of all mercury produced by the application of ultraviolet radiation induced mice skin cancer. Skin cancer were more common in farmers, fishermen and outdoor workers, and good fat in the Head, the back of the hand, such as sunlight exposure-prone areas, to prove the occurrence of skin cancer is closely linked with ultraviolet radiation. In addition, the epidemiologists found that living in equatorial regions of the whites, the incidence of skin cancer than those living in the white areas away from the equator is higher and the incidence of skin cancer and is inversely proportional to the laws of latitude, also sets out the ultraviolet rays carcinogenesis: the lower latitudes from the equator, the closer, the greater the amount of ultraviolet radiation, the incidence of skin cancer higher; the other hand, the high latitudes, far from the equator by a small amount of ultraviolet radiation, the incidence of skin cancer on the low.

 

(3) of ionizing radiation

     Radiation has long been engaged in the work of the past due to neglect of radiation protection measures and lead to dry skin disease based on the occurrence of skin cancer, in recent years due to improvements in radiation equipment and radiation technology, in particular the strengthening of the protective measures, the Occupational Basically, skin cancer has become extinct. However, in some patients to receive radiation therapy after a few years later, in the radiation field occurred in the cases of skin cancer and can still be met. Ionizing radiation of skin cancer is still a risk factor.

(4) pre-cancerous lesions
     Some of the nature of skin disorders such as actinic keratosis (actinic keratosis), xeroderma pigmentosum prone to skin cancer. Burn scars, as well as prolonged chronic non-healing skin ulcers, fistula, sinus inflammation in patients with chronic repeated stimulation are prone to skin cancer, malignant transformation.

1, squamous cell carcinoma of the beginning for the verrucous plaque, or a small light red, yellow nodules, the top of the roof have Keratocyst spines continue to grow, the central rupture, the edge of congestive heart swell. Early for basal cell carcinoma of the hard grain of rice large blood rash, or there is wax-ray-like flat shiny spots, covered by dark brown or gray buff skin, ulcer edge after the hard-like uplift of the embankment.

2, eyes and mouth around a long mole-like things, and soon black uplift.

3, breasts and genitals at first look like eczema-like lesions, but no matter how clean it is difficult healing ointment.

Skin cancer is very rare. In China, the skin cancer malignant Habitat eleventh place in the body. It is precisely because people paid little attention to it, despite the good growth of skin cancer in the exposed skin, at present, the early diagnosis of skin cancer rate is still low. The elderly may be some pre-cancerous skin manifestations, including tumors in senile keratosis, vitiligo is more common, there are a number of chronic skin diseases, burns or trauma, such as keloids after many years of chronic non-healing ulcers, chronic skin Yan, older skin warts, chronic fistula or sinus, such as radioactive ulcer, if after formal treatment, but increased these lesions, or rupture, hardening, thickening, coloring deepened hyperkeratosis and even bleeding, which should guard against the possibility of skin cancer. In short, if the skin in the elderly, there has been a painless nodule, hard texture, edge swell, to go to the specialist hospital for examination, to exclude the possibility of skin cancer.

● regular outdoor activities;

● family of two or more relatives with skin cancer;

● shallow eye color;

● red hair, gold;

● skin easily spotted;

● have a serious sunburn in childhood;

● work in regular contact bitumen, tar, mineral oil people.

 

According to the survey, the United States an average of 70 million people suffer from skin cancer, men suffering from the risk of this cancer are twice as many women because most men do not pay attention to the use of sun protection products, coupled with long exposure time than women, so skin cancer men in the United States the most common, but also the fastest growing cancer. To reduce over-exposure to anti-skin cancer medicine showed that the yellow race of people suffering from skin cancer than white people with low probability, but also can not ignore the risk of skin cancer.
