You mention it is on you lower leg so it must be
a skin lesion that was removed. I work for a dermatologist. There are basically three main types of skin cancer, the most common is Basal Cell Carcinoma, then Squamous Cell Carcinoma and
Malignant Melanoma. By it's name of course malignant melanoma is the most serious as it will
metastisize to other parts of the body if given the chance. Squamous Cell Carcinoma's must be
treated as they have the potential to spread if
left untreated. Usually complete surgical removal and proper healing of the wound is all that is needed along with follow up's with your
doctor to make sure there is no evidence of return. Also, once one has a tendency to develop a skin cancer they have the propensity
to develop more so it's important that you go
for at least yearly check ups, sooner if you find
something questionable. There is a prescription
cream, Aldara & Efudex that is currently being
used to treat pre-cancerous skin lesions such as
actinic keratoses but it is very potent and it
works by removing layers of skin down to a new
layer of undamaged skin. For healing of a surgical wound Aquaphor healing ointment which is
over the counter is good, if there is any sign of
infection there are antibiotic healing ointments
as well as oral antibiotics that can be taken.
Hope this helps.
