Questions about care or symptoms should be directed to the MAC clinic instead of to your oncologist's office in Everett. Most of your questions can be answered by the nurses at Whidbey General. If needed, the nurse will call the oncologist for additional instructions and orders.

Ongoing communication occurs between the MAC clinic and local primary care providers, specialists and Emergency Department staff to help ensure you receive seamless, coordinated treatment across the health care spectrum.

The Cancer Program team at Whidbey General brings many years of experience across numerous disciplines to support you during your cancer journey.

Every nurse who treats cancer patients at Whidbey General is certified in chemotherapy administration. Our interdisciplinary cancer care team includes 10 oncology-certified nurses as well as staff trained in cancer navigation, nutrition, acupuncture, diabetes care, wound-ostomy-continence, tobacco cessation, rehabilitation services and home health care.

We provide chemotherapy Monday through Friday at the MAC clinic. Outpatient care related to cancer treatment includes chemotherapy administration, IV antibiotics, hydration, blood draws and blood and blood product administration. Radiation services are coordinated with nearby providers. Read more about services we provide or call us at 360-678-7624 or 360-321-5173.
