Skin cancer is the consequence of the uncontrolled proliferation of some cells that form the skin. This will form a tumor , which in the case of being malignant, will invade adjacent tissues and may even metastasize. To avoid this disease, do not flee from the sun, but do avoid excessive exposure, as sunburn is the main risk factor for melanoma.. In situations of intense or prolonged exposure, resorting to common sense is basic, and this will tell us to carry an umbrella, go with the right clothes or use sunscreen .
Differences between melanoma and non-melanoma
There are different types of skin cancer. Melanoma is not the most frequent but it is the most dangerous. It is the malignant version of a mole. Metastases are frequent when the diagnosis of melanoma is not early, and they have a very high mortality.
As for skin cancers that are not melanomas, as could be carcinomas and squamous or basal cell epithelioma, rarely metastasize although can invade adjacent tissues locally, which also creates problems if the diagnosis is delayed.
In most cases, the treatment of this type of tumors is surgical. Normally the tumor is completely removed. In some selected cases Mohs surgery can be used, since it gives a greater guarantee that there are no microscopic remains of the tumor on the skin. In very incipient cases of non-melanoma skin cancer, other options can be considered, such as non-surgical ones, such as the application of imiquimod cream, photodynamic therapy , cryotherapy or laser .
As for the detection of melanoma, there ABCDE rule to detect suspicious moles: A symmetrical, with irregular ordes B, C oloración heterogeneous or very dark, D exceeding 6 mm iámetro and E volution or unjustified changes lunar. This detection can give clues to a dermatologist with the naked eye, although dermoscopy helps us see structures that the eye can not see and increases our diagnostic accuracy.
