How many months or years it takes a sunburn to become skin cancers?
I've heard that sunburns do not become cancer the skin immediately. How many months or years it takes for a sunburn to become skin cancer? My friend recently had a sunburn. Its Sunburn was not healing and it became worse, so I went to a dermatologist for 3 months after the sunburn happened. The dermatologist found she has skin cancer. Could it be that she had cancer of the skin all the time, and recent sunburn did not cause her cancer?
I got from Wikipedia that skin cancer is more closely associated with chronic inflammation of the skin. This includes: 1. Overexposure to radiation UV can cause skin cancer either through the direct DNA damage or by the mechanism of indirect DNA damage. UVA and UVB have been implicated in causing damage DNA resulting in cancer. Exposure to sun 10 am-4 pm is more intense and therefore more damaging. Natural (sun) and artificial UV rays (tanning salons) associated with skin cancer. [Citation needed] From hammocks cause DNA damage mainly indirect (free radicals) their use is associated with the deadliest form skin cancer, malignant melanoma. [Citation needed] 2. Chronic nonhealing wounds, especially burns. These are called Marjolin's ulcers based on their appearance, and can turn into squamous cell carcinoma. 3. Genetic predisposition, such as "congenital melanocytic nevus syndrome." NMCs is characterized by the presence of "nevi" or moles of varying size that either appear on or within 6 months of life. Nevi larger than 20 mm (3 / 4 ") in size have a higher risk of becoming cancerous. 4. Skin cancer is one of the potential dangers of ultraviolet germicidal irradiation. The skin can be protected to avoid sunlight altogether, or wear protective clothing while outdoors. Skin cancer is usually caused by exposure of skin to UV rays excessively. Most of the treatment of skin cancers can be treated with surgical excision, ensuring that the edges (margins) are free of tumor cells. These divisions provide the best cure for both early and high risk of disease. For low-risk disease, radiation therapy and cryotherapy (freezing of cancer) can provide sufficient disease, both, however, lower, overall cure rates of surgery. Mohs micrographic surgery control is a technique used to remove the cancer with the least amount of surrounding tissue and the edges are checked immediately to see if a tumor is found. This provides opportunity to remove the least amount of tissue and provide the best cosmetically favorable results. This is especially important for areas where excess skin is limited, as the face. Cure rates are equivalent to wide excision. Special training is required for this technique. In the case of the disease that has spread (Metastasis) or chemotherapy plus surgery may be required.  Scientists have recently been conducting experiments on what it has termed "the priming immune. This therapy is still in its infancy, but it is effective to attack foreign threats like viruses and also adhere to the skin and cancers attack. More recently, researchers have focused their efforts on strengthening the body naturally produces its own "helper T cells" to identify and block cancer cells and help guide cancer killer cells. The researchers infused patients with less than 5 billion of helper T cells without any hard drugs or chemotherapy. This type of treatment if it is proven effective and has no side effects could change the way cancer patients are treated how many months depending on how the skin can deffend of ultraviolet radiation. sorry for my bad english.
