Ultraviolet (UV) rays from the sun or from a tanning bed are the main cause of basal cell carcinoma. When UV rays hit your skin, over time, they can damage the DNA in your skin cells. The DNA holds the code for the way these cells grow. Over time, damage to the DNA can cause cancer to form.
Most basal cell and squamous cell skin cancers are caused by repeated and unprotected skin exposure to ultraviolet (UV) rays from sunlight, as well as from man-made sources such as tanning beds. UV rays can damage the DNA inside skin cells. DNA is the chemical in each of our cells that makes up our genes.Genes contain instructions for how our cells function. We usually look like our parents because they are the source of our DNA.sually the cells can repair the damage, but in some cases this results in abnormal DNA, which may be the first step on the path to cancer. Researchers donât yet know all of the DNA changes that result in skin cancer, but they have found that in many skin cancers the cells have changes in tumor suppressor genes.
