Most moles are considered harmless skin pigmentations that appear as brown or black growths on your skin. They can appear any place on your body at any age. However, some moles can be cancerous so it is important to consult with your doctor. Freezing a mole with liquid nitrogen is an effective way to remove a cancerous or unwanted mole.
How It Works
Freezing a mole is a medical procedure that works by applying liquid nitrogen to a cotton swab and applying it to the mole to destroy its cells. A spray of liquid nitrogen can be used depending on the size of the mole. You will be given anaesthesia before the procedure. Within two to three days your mole will become red and puffy and a blister will form. The blister will heal and fall off within two weeks. This procedure does not typically leave a scar but in certain cases scarring may appear. If a scar develops it should be minimal compared to the surgical method of mole removal.
In the surgical method the mole is removed by creating an incision in your skin to cut away the cells that are creating the mole. The surgical method will leave a scar because of the incision and the stitches required to heal the wound. The freeze removal of a mole does not require stitches and if there is a scar it is less noticeable than the surgical method.
According to the American Academy of Dermatology, if the mole is cancerous it is important to remove the mole so that the cancer cells will not spread to other parts of the body. The freezing method of removal is intended to destroy cancerous cells before they spread to other parts of the body. This form of treatment is not just for cancerous moles; it can also be used to treat other unwanted moles. It is important to consult with your doctor to ensure that your mole is not cancerous.
After freeze removal of your mole you should keep the area that was treated covered to avoid an infection. You should avoid touching or picking at the blister. A blister is a natural part of the healing process and should not be agitated. It is important to follow the doctor's instructions to properly care for the affected area. If the blister does not dry or scab within five days it is important to consult with your doctor. If the area surrounding the removed mole becomes painful you should also seek medical attention as soon as possible.
