If you're like most people, you've been going to physicians ever since you were born and perhaps were not aware whether some or all of them were osteopathic physicians, also known as DOs. You may not even be aware that there are two types of complete physicians in the United States—DOs and MDs. The fact is that both DOs and MDs are fully qualified physicians licensed to prescribe medication and perform surgery.

DOs and MDs are Alike in Many Ways
  • Students entering both DO and MD medical colleges typically have already completed four-year bachelor's degrees with an emphasis on scientific courses.
  • Both DOs and MDs complete four years of basic medical education.
  • After medical school, both DOs and MDs obtain graduate medical education through internships, residencies and fellowships. This training lasts three to eight years and prepares DOs and MDs to practice a specialty.
  • Both DOs and MDs can choose to practice in any specialty of medicine—such as pediatrics, family medicine, psychiatry, surgery or ophthalmology.
  • DOs and MDs must pass comparable examinations to obtain state licenses.
  • DOs and MDs both practice in accredited and licensed health care facilities.
  • Together, DOs and MDs enhance the state of health care available in the U.S.
DOs, however, belong to a separate yet equal branch of American medical care. It is the ways that DOs and MDs are different that can bring an extra dimension to your health care.

The Osteopathic Approach

For more than a century, osteopathic physicians have built a tradition of bringing health care to where it is needed most:

  • Approximately 60% of practicing osteopathic physicians practice in the primary care specialties of family medicine, general internal medicine, pediatrics, and obstetrics and gynecology.
  • Many DOs fill a critical need for physicians by practicing in rural and other medically underserved communities.
In addition, these modern-day pioneers practice on the cutting edge of medicine. DOs combine today's medical technology with their ears to listen caringly to their patients, with their eyes to see their patients as whole persons, and with their hands to diagnose and treat patients for injury and illness.
THE ABCDE’s of Skin Cancer

Here’s what you need to look for when you look at your moles.

A- Asymmetry:
Normal moles or freckles are completely symmetrical. If you were to draw a line through a normal spot, you would have two symmetrical halves. In cases of skin cancer, spots will not look the same on both sides.

B- Border:
A mole or spot with blurry and/or jagged edges.

C- Color:
A mole that is more than one hue is suspicious and needs to be evaluated by a doctor. Normal spots are usually one color. This can include lightening or darkening of the mole.

D- Diameter:
If it is larger than a pencil eraser (about 1/4 inch or 6mm), it needs to be examined by a doctor. This includes areas that do not have any other abnormalities (color, border, asymmetry).

E- Elevation / Enlarging:
A mole or lesion that becomes elevated or changes size may be abnormal.

Note that any of these findings should arouse suspicion, but does not necessarily confer the diagnosis of cancer. A board certified dermatologist such as Dr. Doppelt should evaluate such lesions.
