Our Staff Members

With many years of experience in medical offices and hospitals, the staff at Bala Dermatology enjoys taking care of our patients’ dermatology needs. Our goal is to make your visit in our office as comfortable and easy as possible.

SKIN CANCER SCREENING AND TREATMENT
We care deeply about your health, and want to do everything we can to make sure that we stay on top of any changes. Skin cancer is the most prevalent type of cancer. More new cases of skin cancer are reported each year than cancers of breast, lung, prostate and colon combined. Skin cancer can occur from exposure to the sun over your lifetime, current or past tanning bed usage, as well as genetic factors. It’s important to come and see us for regular screenings, so we can spot problems before they become problems.
WE SCREEN FOR:
Basal Cell Carcinoma
Squamous Cell Carcinoma
Melanoma
Cyst Removal
There are a whole host of medical reasons that cysts can form. We’ll evaluate your cysts, and remove them as painlessly as possible.
Mole Evaluation and Removal
Mole evaluation should become a part of everyone’s regular care. While most moles don’t require treatment at all—unless the patient would like them removed for cosmetic reasons—some moles can be cancerous. It’s important that any changes in mole size or shape be addressed and evaluated as soon as they’re noticed.
