Compared with the general population, it was found that those affected by skin cancer excluding melanoma, showed up about 57 percent higher incidence of new cancer processes after treatment of the first disease. People with skin cancer are more likely to develop another variant of cancer as the rest of the population, according to research conducted in Northern Ireland (UK) and published in the British Medical Journal. The researchers studied the registry funds in Northern Ireland Cancer between 1993 and 2002 and analyzed the cases of 20,823 people treated for skin cancers other than melanoma, and of 1,837 people suffering from melanoma. Compared with the general population, it was found that those affected by skin cancer excluding melanoma, showed up about 57 percent higher incidence of

new cancer processes after treatment of the first disease. It was found that there were many more cases of subsequent melanomas and cancers related to consumption of snuff, and that those with the highest risk were those suffering from squamous cell carcinoma and basal cell carcinoma. In the case of patients suffering from melanoma, a variety that is the cause of most deaths related to skin cancer, the risk of developing another cancer was twofold. The researchers focused on patients who developed cancer differs from the first and excluded those who were metastatic cancer (extending to other parts of the body). "This study confirms that those diagnosed with skin cancer are at increased future risk of developing another cancer, especially one of the other types of skin cancer or those related to snuff," said one researcher, Professor Liam Murray the Queen "s University of Belfast. According to Murray, the recurrent disease is especially in cases of people diagnosed with melanotic or pigmented tumors: "for those with melanoma risk may be more than double that of individuals from the rest of the population." Murray said there are several explanations, the main "excessive sun exposure, so that patients who have had one type of skin cancer have increased susceptibility to the other variants also epidermal disease. "Furthermore, a new skin cancer can be more easily detectable in patients who are monitored after treatment of an initial diagnosis of skin cancer," he said. As for cancers related to snuff, Murray said: "Smoking predisposes to skin cancer and other body parts" and argued that "people who smoke in general is usually less healthy lifestyles, including short aware that excessive sun exposure is bad. " The main risk factor for developing skin cancer, which is the most common form of cancer in the white population, are the ultraviolet rays from sunlight, producing mutations in the DNA of cells that accumulate over the years. Sara Hiom, of the Center for Cancer Research UK, said the importance of this research is that "gives physicians more time to monitor people who have suffered skin cancer and helps them reduce the risk of patients developing a second cancer. Hiom recalled that "around two thirds of melanomas and 90 percent of non-melanoma skin cancers are caused by exposure to ultraviolet rays and occur frequently said sunbathing before age 35 increased by 75 percent the risk of melanoma.
