What types of skin cancer? What causes skin cancer?
There are three main types of skin cancer, three types are likely to be over-exposed to sunlight caused by the at least one possible cause. Ultraviolet radiation from sunlight can destroy the genetic characteristics of skin cells, leading to precancerous changes and cancer cell growth. It is obvious that the most surface of the skin are the first part of the erosion. Three main types of skin cancer: basal cell carcinoma (or rodent ulcer), squamous cell carcinoma and malignant melanoma, are found in the skin called the epidermis surface.
Three types of skin cancer, the most common are basal cell carcinoma, if not treated early, it will cause local tissue erosion, but does not spread to the body
Other parts. Squamous cell carcinoma of the lack of proper treatment, it will spread. Fortunately, these two types of skin cancers grow slowly, almost all cases can be cured. Squamous cell carcinoma is sometimes found in post-menopausal women, the vulva, it would more difficult to handle.
Malignant melanoma in three of the most rare, usually existing moles on the human body becomes, is a cancer of melanocytes. This is the most serious form of skin cancer, after the rapid spread of disease. If detected early, start treatment, the cure rate is about 75%.
Who is most likely to get skin cancer? How to reduce this possible?
Skin and eye color more light, the easier it sunburn, skin cancers may have the greater. The long-term exposure, such as engaging in farming as an outdoor occupation, of course, will increase the possibility of skin cancer; short-term exposure, say, on the beach for sun
Bath, tan skin and blistering, but also have the same harmful effects; even if only a modest seasonal sun, year after year, will increase the possibility of skin cancer. Exposure on the long-term damage to skin cells accumulate, so the possibility of skin cancer in middle age and older.
The easiest way to avoid skin cancer is to reduce exposure to cancer-causing ultraviolet light. There are three basic ways of reducing the damage of UV on the skin, should consider using one or more of: (a) reducing the activities of the time in the sun; (b) when they go out to protect the skin with clothing and headgear; (3) If you must wait in the sun, nor can use clothing to protect the skin, or they wanted to tanning rather than cover the skin with clothing, it should be coated with sunscreen. There sunscreen cream, oil formulations, contain certain chemical composition, can prevent the most harmful sunlight rays damage the skin.
What are the symptoms of skin cancer?
Basal cell carcinoma and squamous cell carcinoma is very similar to the symptoms of malignant melanoma will have special signs. A total of all skin cancer symptoms is change, it is each person must be noted. Basal cell carcinoma and squamous cell carcinoma of the initial rough surface may be just some small patches than the surrounding skin, slightly red or slightly white; it may be small lumps, or a very easy bleeding, heal slowly or not the healing of small ulcers. Start cancer may be very small, like a needle size, if left untreated, cancer cells will spread to surrounding tissue; once the cancer has spread, treatment is more difficult, and prone to leave scars. Sun-sunburn skin occasionally occur with a scaling of the flat reddish patches called actinic keratosis, the disease is not cancer, but may become cancer. Malignant melanoma is the most dangerous form of skin cancer, symptoms are usually skin pigmentation, the color of mole changes in the appearance of new moles, lesions involving produce brown pigment and black pigment cells. Should pay special attention to skin, dark spots, points, or mole changes, alert the formation of a new mole, mole bleeding, dark spot the old and new shape and color change, if we find any of the above symptoms should immediately seek medical treatment, do not delay . Early treatment, malignant melanoma can often be cured; ignored, then the cancer would spread to other parts of the body may attack the vital organs.
What is diagnosis and treatment of skin cancer? If suspected of suffering from skin cancer, what tests should be done?
Because skin cancer grows in the body surface, the first step in diagnosis by the attending dermatologist look. An experienced dermatologist With just a look with the eyes, I know that the skin tumor is not benign. If he suspected skin cancer, will be cut the next small piece of the organization sent to a laboratory microscope. Pathologist (an expert identification of abnormal cells) will determine the cells are not cancerous. This is the case, the dermatologist will choose a number of ways to remove the tumor. Even if the tumor is not cancerous, the doctor may still be to remove the tumor in order to prevent cancerous tumors. Some pre-cancerous skin lesions can be combined with anti-cancer drugs with a skin emulsion to treat. To deal with early basal cell carcinoma and squamous cell carcinoma, the doctor will use scalpel to remove the tumor, or using liquid nitrogen cryosurgery. Cryotherapy using low-temperature kill cancer cells, wound healing in a few weeks, leaving only a little scar, and sometimes even without leaving scars. The use of scalpel or a surgical instrument known as the scraper removal surgery will cause more obvious scar. The benefits of cutting down the doctor can check the organization, and to determine whether the cancer has completely removed. After removal of the cancer can be immediately wound for electrocautery treatment to kill residual cancer cells, was also closed, blood vessels to stop bleeding.
Malignant melanoma compared with basal cell carcinoma and squamous cell carcinoma have a greater potential danger, it is almost always surgical operations to remove the cancer along with a number of organizations around the excision. If the cancer has spread to other parts of the body, may consider using other therapy, such as chemotherapy. Radiation therapy seems to have disease not valid. Treatment of this disease sooner the better.
