The medical community has determined that currently, there is not enough evidence to suggest that regular screenings may do anything to detect skin cancer in the early stages. However, if people do have a history of the disease or do have suspicious moles/spots/changes, it is recommended that they get screened at physicals and other doctor appointments. If a person detects one of the A,B,C,D,E symptoms or any other changes to the skin, it is important to get checked out by a doctor right away.
Once a doctor confirms that an area of the skin is sufficiently suspicious, he or she will usually order a biopsy. This consists of the removal of a piece of or the entire area and sending it to the lab for examination under a microscope. The identity of cancerous cells will confirm the presence of cancer and if so, what type. If melanoma has been diagnosed, further imaging such as X-rays and CT scans may be ordered to determine if and how far the cancer has spread.
