Skin cancers occur under the conditions of a genetic predisposition or association of external factors, the most frequent of which is exposure to ultraviolet radiation.
Cumulative and chronic exposure increases the risk of epithelioma, and intense and intermittent burn-on exposure increases the risk of malignant melanoma.
Other external factors such as carcinogenic substances, chemical burns, pre-existing lesions (such as the presence of melanocytes-moles) for melanoma, etc. are described.
The presence in our skin of a lesion, usually newly emerging, that evolves in time to ulceration, with bleeding, describes a basal cell epithelioma (which often appears on the skin exposed to the sun) or spinocellular (particularly present in the lip level ).
Basal cell epithelioma is the most common malignant tumor of the skin, it starts as a de novo lesion, an erythematosquamous plaque or nodular lesion, with visible surface vessels that, untreated, grows, expands, and evolves, with ulceration, bleeding and, especially, with a local evolution.
If neglected, especially the facial one, evolves in the deep-to-the-bone structures with an invalidating aspect. In fact, this type of tumor has no risk of local or vascular metastasis, the only risk is the locally invalidating evolution.
It mainly affects the areas exposed to the sun, i.e. facial, back of the hands, posterior thorax areas.
The local treatment is curative, the surgical excision is of choice with a 0.5 cm radius and histopathological examination.
When this is not possible it is possible to resort to a number of local ablative therapies, laser therapies, with cure healing, in which case healing can be obtained.
Squamous cell epithelioma affects especially the skin of the lips, is an ulcerated, crust-coated, hardened scar that metastasizes in the loco-regional ganglia if ignored. This also can be treated by cuneiform surgical excision in the early stages of healing.
Any new lesion requires a visit to a specialist physician for a clear diagnosis and for the best treatment option; for these malignant tumors, early diagnosis is associated with a healing-oriented therapeutic option.
