Hi Crowheart, and Mellyuk (if you read here),
Sounds like you both are going through a scary time. Sorry! Crowheart, you are right... don't panic, you don't know the results yet. Although it's taxing emotionally and mentally, concentrate on maintaining your daily routine and health at this time. Getting tired and scared will do nothing but make you more miserable and exhausted.
In regards to the wait time... tissues in the body vary. Some are responsive to pathology tests that are quick and others are not. For example, I had to wait 7 days for results of my lymphnode biopsy because freezing and testing them quickly yields very unreliable and innaccurate results, which you definitely don't want! So be patient and thankful that medical professionals have tests that are accurate.
Also, in response to taking the mole off and the doctor saying you are cured... he may well be right.

Melanoma is a different animal when it comes to cancer. The most research-based "cure" is really removal, not chemo or radiation like in other cancers. If it is indeed melanoma, they may want to remove more tissue around the site (called a wide excission). The extent of the excission would depend on the stage of the Breslow's Thickness of the melanoma. So, take heart! You really may be cured!!! I had a wide excission, and I am cured!
Please do let us know your results when they come in, and rest well.
