Dr. Aradhna Saxena does Melanoma Treatment Lansdale, PA Of the various types of skin cancer, melanoma is fortunately one of the least commonly diagnosed. At the Dermatology and Skin Cancer Institute, our physicians and team have the extensive background in the diagnosis and treatment of all skin cancers. Our experience in our field enables us to discuss the details of various treatment options with our patients and to assist them in determining how best to treat their condition.

Melanoma is most often treated with surgical removal. Dr. Saxena provides two types of skin cancer removal:

Modified Mohs Micrographic Surgery for Melanoma

At the current time, the Mohs procedure is not the standard of care for treatment of melanoma. This is because successful removal in Mohs surgery relies on the accurate microscopic view of specific tissue features, and those in the lentigo maligna may be lost in the quick-freeze process used in the standard Mohs procedure.

"Slow Mohs" or Modified Mohs Surgery is completed in much the same way as the traditional Mohs procedure. Both are performed in our office on tissues numbed with local anesthetic. Both share the goal of preserving the greatest amount of healthy tissue while ensuring the successful elimination of cancerous cells. Where "Modified Mohs surgery" differs is in the handling of tissue, processing sections that have been placed in a block of wax overnight before being sliced into ultra-thin layers for evaluation under a microscope. Because tissue is not frozen, the features needed for accurate evaluation remain intact. Once the deep and peripheral margins are confirmed clear by the pathologist, reconstructive surgery can be arranged to minimize scarring. The "Modified Mohs surgery" procedure boasts a five-year cure rate between 95 and 99.5 percent.1

"Modified Mohs surgery" and traditional Mohs surgery are similar in many ways, but the slower procedure takes a few days for completion due to tissue being sent to a laboratory. Traditional Mohs, due to immediate evaluation of tissue, is completed within a few hours. Visits at the Dermatology and Skin Cancer Institute for the "Modified Mohs surgery" procedure, whether for tissue removal or for reconstruction, typically last 30-40 minutes.

We are happy to provide you with further information regarding Mohs Micrographic Surgery and the "Modified Mohs surgery" procedure. Please contact us to schedule your consultation with Dr. Saxena.

Surgical excision for Melanoma

When melanoma occurs on the extremities or the trunk of the body, definition of the tumor borders tend to allow successful removal using a standard excision technique.

In an office visit lasting about 40 minutes, Dr. Saxena outlines and then excises the melanoma tumor under local anesthesia. Margins are those set forth by national guidelines. As necessary, tissue in the excision area is immediately reconstructed to minimize scarring.

Tissue excised in this procedure is thoroughly evaluated in an off-site laboratory . Re-excision to remove residual cells is needed in less than 5 percent of cases.
