I am a board certified diagnostic radiologist who is a specialist in breast imaging. For the past 15 years I have devoted 95% of my professional time to the detection and diagnosis of breast cancer and other breast diseases. I was instrumental in the genesis of the Seattle Breast Center (SBC) in the early 1990s, which was the first comprehensive breast center of its kind in the Pacific Northwest, currently offering a full range of services, including screening and diagnostic digital mammography, breast ultrasound with Shear Wave elastography, breast MRI and minimally invasive image-guided breast biopsies. I have been the medical director of the SBC for many years and have taken pride in offering state-of-the-art breast imaging services. The SBC was the first facility in the region to offer stereotactic-guided needle biopsy and subsequently the first non-academic center to provide MRI-guided needle biopsy. We have a high risk breast cancer screening program that includes a computerized risk assessment for all of our patients, BRCA gene mutation testing, and breast MRI screening when indicated. Consulation with one of our breast imaging radiologist specialists is available for those women who may be at high risk for developing breast cancer during their lifetime. During my long career in breast imaging I have given numerous lectures, both locally and nationally, to physicians and other health care professionals. For many years I participated in teaching national workshops on minimially invasive breast biopsy techniques. I am a longstanding member of the Society for Breast Imaging and a member of the Scientific Advisory Panel for Hologic, a major women's health care company that includes the design and manufacturing of mammography, breast ultrasound, and breast biopsy equipment.

Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.

A 37-year-old member asked:

Surgical excision: Most small lumps in the armpit, particularly if superficial, are sebaceous cysts due to a damaged hair follicle. Unless they become large and bothersome, most sebaceous cysts can be left alone. The most important thing is to have the lump examined by a qualified health care professional to make sure that it is indeed most likely a sebaceous cyst and not something of more concern.

Not usually.: Calcification in a pulmonary nodule almost always indicates a benign cause, usually a granuloma or hamartoma. However, calcification can also be associated with malignant lesions. The pattern of calcification demonstrated on a ct scan may be helpful in distinguishing a benign from malignant cause. However, any nodule that increases in size may indicate a malignancy and should be biopsied.
A 40-year-old male asked:
Dr. Craig Hanson

Yes: Calcification in a solitary pulmonary nodule indicates a high probability that the lesion is benign (not malignant). However, some malignant lesions can calcify and any time a mass or nodule is enlarging one has to be concerned about the possibility of a malignancy. The only way to determine this is with a biopsy, which can usually be done with a needle under imaging guidance (flouroscopy or ct).
