• New Cases: 22,700 per year

• Symptoms: Lump in breast or armpit, changes in breast size or shape, changes in skin temperature, redness or swelling, inverted nipple, crusting or scaling on nipple.

• Screening: Mammography (once every two years recommended for women ages 50 to 69); clinical examination (once every two years recommended for women over 40); self-examination. Women with family history of the disease should ask a doctor about a personal plan.

• Treatment: A lumpectomy removes the tumour while conserving most of the breast. A mastectomy removes the entire breast and sometimes the lymph nodes. Radiation is used to treat many stages of breast cancer and frequently used after a lumpectomy. Biological therapy helps the body’s immune system fight cancer. Herceptin is used to treat human epidermal growth factor positive (HER2) tumours.

• Latest Research:
Research funded by the Canadian Cancer Society includes assessing what information patients require about complementary therapies, the use of MRI to detect if the cancer has spread, investigating whether combining various anti-cancer drugs can activate genes that prevent spreading.
