In most people's view, had more than one cancer death is only a certain percentage chance of a cancer is high, but in fact is not necessarily. For the United States a study of cutaneous melanoma has brought an unexpected result: suffering from a malignant melanoma of the probability of death while suffering from a variety of melanoma 13.6 times.
Not common but high mortality
Melanoma is a skin cancer, because melanocytic lesions produced. Melanoma cells were mainly present in the skin, and less exist in other parts of the body. Although melanoma is not common, but it is the main skin cancer cause of death, with regard to the American Cancer Society statistics, estimated in 2013 there will be 76,600 cases of melanoma occur.
The study by University of New Mexico Cancer Center, published in JAMA (Journal of the American Medical Association, JAMA). According to the results of the study, people with a variety of primary tumors and tumor thickness of 4mm or deeper, then, than the thickness of only 1mm in mortality is three times higher; patients have only one primary tumor and tumor thickness of 4mm or deeper, then, the mortality rate than the thickness of only 1mm, but suffering from a variety of melanoma patients 13.6 times higher.
Tumor thickness is the key
Presided over the study Dr. Marianne Berwick, their research suggests that people with a variety of melanoma patients with certain immune mechanism to monitor the development of melanoma. The results also show that, even if one or more of the condition similar to melanoma, melanoma thickness and the degree of correlation is also likely to die than got between several larger melanoma.
Because if melanoma skin thickening, skin inner growth to a higher risk, like a tip of the iceberg as viewed from the outside does not come out, so if a mole or dark skin patches suddenly becomes large, irregular shape, color shades and other "not the same as with the usual" situation, should consult a doctor recognized causes.
The study gathered the United States, Canada, Australia and Italy, 3372 and 1206 multiple single melanoma melanoma patient data to be compared together.
