1. What is basal cell carcinoma?

Basal cell carcinoma (BCC) is a malignant tumor composed of cells that resemble those in the basal layer of the epidermis. The true origin of basal cell carcinoma is not clear. In the study, morphological and immunological similarities were found between the basal cell carcinoma cells and the outermost cells of the hair follicle. Experts believe that basal cell carcinoma originates in the hair follicle.
This is the skin cancer with the highest rate, accounting for 75% of other skin cancers, common in people over 50 years old and manifests in many different forms.

Sunshine The ultraviolet rays in the sun are considered by researchers to be the main cause of skin cancer, including basal cell carcinoma. Outdoor workers who are regularly exposed to the sun have a very high risk of basal cell carcinoma. 80% of basal cell carcinoma lesions are in the open skin.
Genetic Variations In patients with an inactive P53 gene, 50% of these patients develop skin cancer by the age of 30 and 90% by the age of 70. In addition, congenital BRAF mutations. can cause basal cell carcinoma.
In addition, some risk factors that make people more susceptible to basal cell carcinoma are:

The principle of disease treatment is to thoroughly remove the cancerous tissues, and at the same time treat the defects caused by the disease lesions to ensure function and aesthetics after resection of the damaged tumor.
Currently, patients with basal cell carcinoma can be treated with surgery such as:
Wide excision of the lesion: This is the most indicated measure, the skin incision is far from the lesion margin. from 0.3 to 0.5 cm. Mohs surgery: Is a method of treating skin cancer with good results. Cryosurgery Using photochemotherapy. Reconstructive blepharoplasty uses local or remote skin flaps, full-thickness skin grafts, or split skin grafts.
