I had an area on my face which returned 3 times. The first time the physician froze it. That was in 2001. In 2005, it returned and he numbed it real good which was EXTREMELY painful since it was above my upper lip. He scraped it really REALLY well and sent it for biopsy. Results were that it was a pre-cancerous lesion. It returned again this year 2008. He numbed the area again and did a punch biopsy where they cut it out, go deeper, and closed it with 2 stiches. The reason for the punch biopsy where they go deeper and more diameter is to attempt to get it all with the biopsy in case it is cancer. My final diagnosis was Basal Cell Carcinoma which of course is cancer and he got all of the lesion while he was doing the biopsy. I don't need any further treatment at time because he did remove a large enough sample to diagnose it and remove it. I had another lesion the first time, in 2001, which he froze and it never returned. I don't even remember where it was now, but I know there were 2 at that time. Basal Cell Carcinoma is the most common skin cancers and needs to be removed as they come. More serious skin cancers like Melanoma need more serious treatment. Continue to keep an eye on as much of your body that you can see and have someone else look at the areas you can't see. Early diagnosis and treatment for skin cancer is the same as any cancer, it greatly increased the ability to be treated successfully.
