Unlike other cancers, the vast majority of skin cancers have no potential to spread to other parts of the body (metastasize) and become life-threatening. There are two major types of skin cancer: basal cell carcinoma (the most common) and squamous cell carcinoma (the second most common). Melanoma is also a form of skin cancer but is far less common, though more dangerous, than the other two varieties.
The definition of backfill is material used to refill a hole, usually what was previously dug out of the hole. Dirt and gravel are examples of backfill. Backfill is defined as to return soil and other materials to a hole after it was dug.
The excavation that formed the grave. Excavations vary from a shallow scraping, to removal of topsoil to a depth of 6 feet (1.8 metres), or more where a vault or burial chamber is to be constructed.he material dug up when the grave is excavated. It is often piled up close to the grave for backfilling and then returned to the grave to cover it. As soil decompresses when excavated and space is occupied by the burial not all the volume of soil fits back in the hole, so often evidence is found of remaining soil.
