Breast oncology involves a range of medical terms that might be unfamiliar. This glossary is designed to help you understand the key terminology you might encounter during your breast cancer journey.
| Adjuvant Therapy Additional cancer treatment given after the primary treatment to lower the risk of the cancer coming back. |
Axillary Lymph Node Dissection The surgical removal of many lymph nodes from the underarm area to determine if breast cancer has spread. |
Biopsy A medical procedure that involves the removal of a small amount of tissue for examination under a microscope to check for cancer cells. |
Breast Reconstruction A surgical procedure to rebuild the shape and look of a breast, often after mastectomy or lumpectomy. |
| Chemotherapy(Chemo) A type of cancer treatment using drugs to destroy cancer cells. |
Ductal Carcinoma In Situ (DCIS) A non-invasive cancer where abnormal cells are found in the lining of a breast duct. |
Flap Reconstruction A type of breast reconstruction surgery where tissue is taken from other parts of the body, like the abdomen or back, to create a new breast mound. |
Herceptin(Trastuzumab) A monoclonal antibody used as a targeted therapy for HER2-positive breast cancers. |
| Hormone Therapy Treatment that adds, blocks, or removes hormones to slow or stop the growth of cancer cells that use hormones to grow. |
Implant Reconstruction A breast reconstruction technique where silicone or saline implants are used to form a new breast mound. |
Invasive Ductal Carcinoma (IDC) The most common type of breast cancer that begins in the milk ducts and spreads to nearby tissue. |
Lumpectomy A surgical procedure that removes only the tumour and a small margin of surrounding tissue from the breast. |
| Magnetic Resonance Imaging (MRI) A non-invasive imaging technique that uses powerful magnets and radio waves to create detailed images of the breast. |
Mammogram An X-ray picture of the breast used to detect and diagnose breast disease. |
Mastectomy A surgery to remove all breast tissue from a breast as a way to treat or prevent breast cancer. |
Neoadjuvant Therapy Treatment given as a first step to shrink a tumour before the main treatment, which is usually surgery, especially in cases where the tumour is large. |
| Oncologist A doctor who specializes in treating cancer. |
Oncoplastic Surgery A procedure combining cancer surgery with plastic surgery techniques to remove cancer tissue and reconstruct the breast in the same operation. |
Radiation Therapy Treatment with high-energy rays (such as X-rays) to kill or shrink cancer cells. |
Reconstructive Breast Surgery Procedures performed to restore the appearance of the breast after mastectomy or lumpectomy. |
| Sentinel Lymph Node Biopsy A surgical procedure used to determine if cancer has spread beyond a primary tumour into your lymphatic system. |
Targeted Therapy A type of cancer treatment that uses drugs designed to target specific cancer cells and avoid damaging normal cells. |
Tumour An abnormal mass of tissue that can be benign (non-cancerous) or malignant (cancerous). |
