During a biopsy, a small sample of the skin tissue from the mole is collected and examined to determine if the cells are cancerous. When a cancerous mole is identified, it needs to be removed right away so that the cancer doesn't spread beyond the skin and affect other parts of the body. There are several ways to get rid of moles, and the procedure is often simple.
The mole (abbreviation, mol) is the Standard International ( SI ) unit of material quantity. One mole is the number of atom s in precisely 12 thousandths of a kilogram (0.012 kg) of C-12, the most common naturally-occurring isotope of the element carbon. This number is equal to approximately 6.022169 x 10 23 , and is also called the Avogadro constant. The mole is the only fundamental SI unit that is dimensionless. That means it represents a simple numerical quantity or value; it is a term similar in nature to dozen (meaning 12) or gross (meaning 144). But 1 mol is, unlike a dozen or a gross, an incomprehensibly large number.
