• To test an OIR diagnostic medical tool (imaging probe) that is designed to be used for early detection of skin cancers. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]
  

• To find out if the imaging probe can help dermatologists in checking lesions that may be cancerous. [ Time Frame: 3 Years ] [ Designated as safety issue: No ]
  

The OIR imaging probe is designed to reflect light in a special way in order to take pictures of pigmented skin.

As part of your standard of care, your physician will check all skin lesions that may possibly be cancerous or pre-cancerous. Your physician will also check any non-cancerous lesions that are being removed for cosmetic reasons, such as warts and freckles.

If you agree to take part in this study, the study doctor will decide which lesions will be biopsied, as well as which lesions are eligible to be imaged.

Pictures of the lesions (as well as healthy tissue nearby) will first be taken using a digital camera. The imaging probe and the area of the skin to be imaged will be cleaned with alcohol. After the imaging probe is placed over the lesion, a drop of baby oil will be applied to the skin. The imaging probe will then be lowered into contact with the skin, and the study staff will begin imaging. Twenty (20) images from 4 different positions will be taken per lesion.

Care will be taken to make sure that you cannot be identified from these images. For example, the study staff will avoid taking pictures of the face unless there are lesions there. After each lesion is imaged, the imaging device will be taken away and the skin surface cleaned. The entire imaging procedure, including preparation time, will take about 5 minutes per lesion.

Any hair on or around your lesions will be shaved or trimmed, if necessary. After all of the imaging is over, your lesion(s) will be biopsied. Your study doctor will decide which lesions require this kind of treatment as part of your standard care. Depending on what the study doctor decides, you will have either saucerization biopsies or excisional biopsies. A saucerization biopsy removes the entire lesion by cutting under it in a "scoop-like" manner. An excisional biopsy "cuts away" the entire lesion along with part of the surrounding skin.

A pathologist will receive your biopsied tissue and perform routine tests on the tissue. The test results will be available to the study doctor.

Depending on whether the results are negative or positive, you may be informed of the results, as the biopsies are standard of care.

The images of your skin will be used for research to try to make the imaging probe more effective.

If you end your participation in this study early, your photographs and information will be removed from the researchers' database at that time.

However, a record of your participation will remain in the database.

After all of the imaged lesions are biopsied, your participation in this study will be over.

This is an investigational study. The OIR imaging probe has not been approved by the FDA. Up to 1,000 patients will take part in this study. All will be enrolled at M. D. Anderson.
