Cancer Care (Hematology and Oncology)

If you or a loved one has cancer, expert cancer care is nearby, in Prosser. Astria Health offers convenient cancer care with world-class oncology experts and in a supportive caring environment. Dr. Amer Khouri provides treatment in Prosser. Also available, the Astria Sunnyside Hospital Cancer Center has experienced cancer specialists who provide highly advanced oncology and hematology services along with support for your emotional and spiritual needs.


We offer care and services you might expect to find at a large urban-based cancer hospital, right in the lower valley.

Our cancer services include:

  • Cancer diagnosis, imaging, and genetic testing. Our experts use top-of-the-line medical imaging equipment to diagnose cancer and create a treatment plan tailored to meet your needs. Genetic testing can help you understand your risk for inherited cancer. Our team can provide testing and help you understand the results—and what, if any, steps you should take as a result.
  • Solid malignancies. Breast cancer, colon cancer, kidney cancer, gastrointestinal cancers, among others
  • Blood malignancies. Leukemia, lymphoma, myeloma.
  • Other blood disorders. Anemia, thrombocytopenia, pancytopenia, coagulation disorders
  • Second opinions about a cancer diagnosis or treatment plan. Cancer is a complex disease, and it makes sense to get a second opinion before moving forward with treatment. Our team can help. We offer a second opinion, and no referral is required for this service.
  • A cancer support group and family counseling. Our cancer support group is for people with cancer, their family members and their caregivers. This group meets every third Monday at 6 pm at 906 E Edison Ave in Sunnyside. The group offers a safe, private space to share stories, provide encouragement and receive support from others who've been there.


The team at the Astria Health features two Board Certified Hematologist/Oncologists. We're fortunate that these top cancer doctors believe that rural areas, like ours, deserve the very best in healthcare.
