Skin cancer is the most common body. It is usually caused by excessive exposure to UV rays, both the sun and artificial sources (tanning beds with ultraviolet rays). These rays penetrate the skin and are damaging, effects can be much later.
Common areas where skin cancer is generated
Regarding the main cause of skin cancer, exposure to ultraviolet rays, parts of skin more sun exposure are those with higher incidence. For example, the most common sites would be nose, forehead, neck and ears, or even the back of the hands.

Appearing on the skin can be easily detected, only subject to the moles or black spots growing skin, itch, bleed or have a change in a short time. If diagnosed in its early stages can be reached heal completely, but if detected at a late stage tumor with a high mortality rate.
The skin has memory: a burn can lead to melanoma or skin cancer
It is true that the skin has memory. This is a demonstration that alterations of nucleic acids are altered skin when receiving ultraviolet rays. These changes add up over time and eventually result in skin cancer. This means that not manage to repair the physiological alterations (occurring at night), is completed.

Any reappearance of a skin lesion or a change in an injury that we should be warning signal to go to the doctor's expert Dermatology. Thus, for example, it would urge the reappearance of a mole or other growth.
What is Mohs micrographic surgery for skin cancer and its advantages
Mohs surgery is to remove the tumors by microscopic analysis of the edges of the tumor during surgery. This is an especially useful technique in:- Tumors that recur once removed- Tumors located in aesthetically important, such as the nose or eyelids, where the skin millimeters we save will be important to minimize the aesthetic defect intervention, ensuring maximum cure rate areas.
The advantages of Mohs surgery to treat skin cancer are proportional to the maximum security in their complete removal, leaving minimal scarring, to save healthy tissue is not necessary to remove.
Other techniques for treating skin cancer
Now they begin to use the sentinel node in melanoma and photodynamic therapy, both treatments already being implemented as routine.
