This requires a close supervision with your oncologist and dermatologist. Squamous cell carcinoma requires surgical therapy. Involvement of other structures may require systemic chemotherapy. For more localized disease, the above procedures may be indicated.
Do discuss this with your physician. I feel that he/she is the best person to explain all these options with you. At this point, stay positive and have a close follow up with your physician. Discuss your concerns with your family and with your doctors. Things are not that bad with prompt and proper management.
