Skin Cancer Treatment and Services

Dr. Park provides surgical treatment of skin cancer and benign (noncancerous) skin tumors. He cares for referred patients from all over Oregon, and performs both Mohs Micrographic Surgery and/or wide local excision of skin cancers.

Mohs Micrographic Surgery

Medical professional looking into microscope Mohs Micrographic Surgery is a state-of-the-art treatment for skin cancer. With this treatment the physician serves as surgeon, pathologist AND reconstructive surgeon. It relies on the accuracy of a map of the diseased tissue area and the precision of a microscope to trace out and ensure complete removal of the skin cancer down to its roots.

Immediate on-site microscopic examination of the tumor allows the physician to see beyond what is visible to the eye and precisely identify the diseased tissue and remove only the diseased tissue, allowing for preservation of the uninvolved tissue.

Dr. Park is a fellowship-trained Mohs surgeon and therefore has extensive training in reconstructive surgery. He is generally able to perform the reconstructive surgery on the same day, immediately after microscopic analysis confirms that the cancer is completely removed.

Mohs Micrographic Surgery is usually performed on an outpatient basis, in one day, under local anesthesia. The healing process is similar to that of most surgical procedures. Of all treatments for skin cancer, Mohs Micrographic Surgery offers the highest cure rate (up to 99% for basal and squamous cell carcinomas) with minimal discomfort and the greatest preservation of normal tissue, thereby minimizing scarring.

When Is Mohs Surgery Appropriate?

While there are a number of methods to treat skin cancer, there are many advantages to Mohs surgery compared to other skin cancer treatments; including its high cure rate and cost-effectiveness. Mohs surgery has become the treatment of choice for basal and squamous cell carcinomas. However, Mohs surgery is not appropriate for all skin cancers and is generally reserved for tumors of the head, neck, hands, feet and genitalia; where preserving cosmetic appearance and function are important.

Other situations where Mohs may be appropriate:

  • Tumors that have recurred after previous treatment
  • Tumors located in scar tissue
  • Rapidly growing tumors
  • Tumors that are ill-defined
  • Tumors that are at a high risk for local recurrence

There are many considerations when determining whether to treat a skin cancer with Mohs surgery. In situations that do not meet the above criteria, the tumor may be treated instead by wide local excision. Your referring provider will discuss treatment options with you and determine the best course of action prior to referral to our office.
