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 ...
Ductal carcinoma in situ, also called DCIS, is a type of breast cancer that's not invasive. It happens when cancer cells form in a breast duct. The cancer cells stay in the duct and don't spread into the breast tissue. It's sometimes called noninvasive cancer or stage 0 breast cancer. HER2-positive breast cancer.
回答 Karthik Giridhar, M.D. HER2 阳性乳腺癌是一种被称为人表皮生长因子受体 2（HER2）的蛋白质检测呈阳性的乳腺癌。. 这种蛋白质对癌细胞的生长有促进作用。. 每 5 名乳腺癌患者中大约有 1 名患者的癌细胞中含有用于制造 HER2 蛋白质的额外基因拷贝。. HER2 阳性乳腺 ...
The vaccine is intended to be used in combination with trastuzumab (Herceptin), an immune-stimulating drug given after HER2 tumor removal surgery. If it works, the vaccine could help prevent the return of the breast cancer, which can be hard to treat once it spreads to other parts of the body. Mayo Clinic researchers recently received a grant ...
El cáncer de mama HER2-positivo es un tipo de cáncer que da un resultado positivo para una proteína llamada receptor 2 del factor de crecimiento epidérmico humano (HER2). Esta proteína fomenta el crecimiento de las células cancerosas. En aproximadamente 1 de cada 5 cánceres de mama, las células cancerosas tienen copias extra del gen que ...
If your cancer makes extra HER2 protein, drugs that target that protein can help decrease the chance of the cancer recurring. Bone-building drugs. Taking bone-building drugs reduces the risk of cancer recurring in the bones (bone metastasis) in people with an increased risk for breast cancer recurrence. Maintaining a healthy weight.
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 ...
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 ...
Beams of radiation are precisely aimed at the cancer using a machine that moves around your body. 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.
HER2 is a protein that some healthy breast cells make. Some breast cancer cells develop changes that cause them to make a lot of extra HER2. Treatments can target the cells that are making extra HER2. Invasive lobular carcinomas are less likely to make extra HER2, so they're less likely to respond to this treatment.
