Breast Cancer Symptoms

Breast cancer can progress for years before a lump is felt, or other symptoms occur. That’s why annual mammography screening is vitally important for women age 40 and over, as well as regular clinical breast exams. Women may also opt to do self-breast exams. The following symptoms may indicate breast cancer:

  • A lump in the breast or armpit that is hard, has uneven edges
  • Change in the size, shape, or feel of the breast or nipple -- redness, dimpling, or puckering
  • Fluid coming from the nipple

Although rare, men can also get breast cancer. Symptoms include a breast lump and breast area pain.

Breast Cancer Diagnosis

If a suspicious lump is felt, or if there are abnormal findings on a screening mammogram, you may be referred for further testing. We offer the following array of diagnostic tools:

  • Digital mammography, both screening and diagnostic
  • A mobile digital mammography unit, serving women in the surrounding three-state area
  • Breast ultrasound
  • Breast Specific Gamma Imaging (BSGI), which relies on the biologic activity of tumors to produce images (available in Sioux Falls)
  • Stereotactic and ultrasound guided biopsies
  • Ductography (also called galactography or ductogalactography), which is contrast enhanced mammography used for imaging the breast ducts (available in Sioux Falls)
  • Breast MRI and MRI guided breast biopsy
  • Genetic counseling for breast cancer patients (available in Sioux Falls)
  • High Risk Breast Cancer Prevention Clinic offered for women with an elevated risk of breast cancer (available in Sioux Falls)
  • DEXA bone density testing
  • Contrast Enhanced Spectral Mammography (CESM)

Breast Cancer Treatment

The Avera Breast Center emphasizes individualized treatment plans for each woman. These plans are developed through the expertise of breast cancer specialists and a multidisciplinary Breast Conference team that reviews each breast cancer case at Avera. A Breast Cancer Consult Service offers a second consultation to newly diagnosed patients. A Breast Navigator is available to each patient as a supportive resource throughout all phases of cancer care. Patients may need one or a combination of treatments including surgery, chemotherapy or radiation.

  • Support programs for breast cancer patients and survivors include A Time to Heal; Cancer Fitness Programs; Look Good, Feel Better; the wig program; Young Women Affected by Breast Cancer; and Metastatic Breast Cancer Support Group.
  • After completing treatment, breast cancer survivors are offered a one-on-one transition visit to help them transition from active treatment to long-term survivorship. Patients receive a detailed summary of their diagnosis, treatment and recommendations for future follow-up care.
