Treatment
Uses
- Liquid nitrogen is used to freeze and destroy abnormal skin tissues. This can include warts, moles, skin tags, sun spots and nodules as well as actinic keratoses and other pre-cancerous growths. It can also be used to treat tumors inside the body but is a far more common treatment for external skin growths.

- The treatment causes a stinging and burning pain while the growth is being frozen and this burning continues while it thaws. The area that was treated will become red and swollen and in 3 to 6 hours a blister with a scab will form. The blister may bleed a little and it may turn purple or black, all of which is a perfectly normal part of the healing process. Within 1-2 weeks, the scab w…
Results
- If your growth requires deep freezing, there may be considerable blistering, discomfort and swelling, especially if your hands or eyelids were treated. The blisters and swelling are part of the treatment and will gradually heal by themselves. If the pain is too much for you, you can take a standard pain reliever such as Tylenol or Aspirin to relieve it.
Effects
- The most obvious after effect is the presence of a blister. You should never try to remove the blister yourself as this could leave you open to the possibility of infection. This means you should avoid rubbing the blister or getting it wet for 24 hours after treatment.
Diagnosis
- If you start to experience the signs of an infection, such as fever, swelling, tenderness and oozing from the site, you should notify your doctor immediately. If the growth is not cured by liquid nitrogen, please make a return appointment, as the growth may be an early skin cancer and may require surgery.
Risks
- If you do decide to try one of these treatments out, its a good idea to talk to your doctor first just to make sure the product is safe and wont cause any additional damage.
