I used to work in OB-Gyn for 8 1/2 years. Severe dysplasia is something to worry about, however, at least you have found it. Severe dysplasia is not cancer, it is pre cancer. Which means that if left untreated, it would become cancer. A lot of women have dysplasia. The severity depends on when it is caught. Most likely your Dr. will have you in for a colposcopy with biopsies. This means he will use a binocular type instrument to view your cervix, and will use another instrument to snip biopsies. The biopsies will then be sent to the lab for the Pathologist to read. At that point depending on the outcome, your Dr. will either choose to follow you closely with pap smears, schedule you for an in office procedure called a Leep, or worse case you would have to have a hysterectomy. I would say most women have a Leep when they have severe dysplasia. A Leep is when the Dr will use the same instrument that looks like binoculars to see your cervix, but he will use a heated instrument that slices (like a hot knife through butter) and remove the dysplasia and their surrounding areas. These will also be sent for Pathology results to insure that the physician got all of the areas. Then you will have to follow up with pap smears. The Leep is a fairly simple procedure, and it won't be difficult for you to go through it. Esspecially after being banded. (Ha, Ha).
If you do end up with the Leep it is not the end of the world, however, be aware!! If you plan on having any future children, it is very important to tell the physician you had the Leep. Depending on how severe the dysplasia is and how aggressive your Dr. is with it, you may have to have a cervical circloge to insure you don't have the baby prematurally due to a weakend cervix. I really hope this helps. I have seen all of these things a lot, and it truly is a blessing that you have had it found earlier, better than later. Good Luck!!!
