HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). This protein promotes the growth of cancer cells. In about 1 of every 5 breast cancers, the cancer cells have extra copies of the gene that makes the HER2 protein. HER2 -positive breast cancers tend to be more ...
Cancer cells with unique appearances. Some subtypes of breast cancer are named for the way they appear under the microscope. Subtypes include tubular, mucinous, medullary and papillary. Your subtype gives your doctor some clues about your prognosis and how your cells may respond to treatment.
If you had triple negative breast cancer, you may have an increased risk of breast cancer recurrence. Triple negative breast cancer cells don't have receptors for estrogen or progesterone, and they don't make too much of a protein called HER2. Obesity. Having a higher body mass index increases your risk of recurrence. Prevention
It is a treatment for HER2 positive early stage breast cancer after surgery. It is only for people who had drug treatment before surgery. It is only for people who had drug treatment before surgery. And when they had the operation the surgeon found cancer cells nearby either in the breast or lymph nodes.
Radiation therapy Enlarge image. Radiation therapy for breast cancer uses high-energy X-rays, protons or other particles to kill cancer cells. Rapidly growing cells, such as cancer cells, are more susceptible to the effects of radiation therapy than are normal cells. The X-rays or particles are painless and invisible.
HER2-positive breast cancer; Triple-negative breast cancer; High-grade breast cancers; Cancers that have spread to the lymph nodes; Larger breast cancers; Chemotherapy as the primary treatment for advanced breast cancer. If breast cancer has spread to other parts of your body and surgery isn't an option, chemotherapy can be used as the primary ...
The stages of breast cancer. The stages of breast cancer are indicated using Roman numerals ranging from 0 to IV, with 0 indicating cancer that is noninvasive or contained within the milk ducts. Greater numerals indicate a more invasive cancer. By stage IV breast cancer, also called metastatic breast cancer, the cancer has spread to other areas ...
Trastuzumab is a type of targeted cancer drug called a monoclonal antibody. Targeted cancer drugs work by ‘targeting’ those differences that help a cancer cell to survive and grow. It is a treatment for cancers that have large amounts of a protein called human epidermal growth factor receptor 2 (HER2). Human epidermal growth factor 2 (HER2 ...
Stage 3 breast cancer. Stage 3 means that the cancer has spread from the breast to the lymph nodes close to the breast, to the skin of the breast or to the chest wall. It is also called locally advanced breast cancer. The stage of a cancer tells you how big it is and how far it has spread. It helps your doctor decide the best treatment for you.
The most common targeted therapy medicines for breast cancer target the protein HER2. Some breast cancer cells make extra HER2. This protein helps the cancer cells grow and survive. Targeted therapy medicine attacks the cells that are making extra HER2 and doesn't hurt healthy cells.
