Skin lesions can be benign or malign.

Although people need to be excessively concerned with this subject, to the point of losing their peace of mind, they should however be attentive.

For example, it is important to observe if a skin spot is changing its shape, color or is showing any kind of prurigo (itching). If any of these signs are observed, the doctor should check them.  

The specialist can make a hypothetical diagnosis by a simple examination (dermatoscopy) and if necessary, a biopsy is requested. They are simple and out-patient procedures. If the lesions have benign characteristics but even so the patient wants them removed (warts and spots), for the discomfort caused by their undesirable location, the best resource is cauterization or a simple removal and suture.

In case of a malign lesion, the doctor will supervise the treatment according to each case. Thankfully, most malign skin tumors are of a basocellular kind that, even being malign, is generally not very aggressive: they grow slowly and do not cause metastasis (implants at a distance).

The more serious skin lesions are spinocellular tumors and melanomas, which will receive appropriate treatment under medical orientation.

It is very important that skin lesions (signs and pints) are examined by specialists before they are approached (dermatologists or trained plastic surgeons) so that the prognosis is accurate, avoiding relapses (which can always happen) or complications by inadequate approaches.
