What does her2 positive mean?
HER2 is a growth-promoting protein on the outside of all breast cells.
Breast cancer cells with higher than normal levels of HER2 are called HER2-positive.
These cancers tend to grow and spread faster than other breast cancers, but are much more likely to respond to treatment with drugs that target the HER2 protein..
What is the survival rate of her2 positive breast cancer?
For perspective, most patients with stage 1 HER2-positive breast cancer, receive targeted therapy drugs like trastuzumab (brand name Herceptin) and pertuzumab (brand name Perjeta) and chemotherapy. This approach results in a 7-year disease-free survival rate of about 93%.
Is chemo necessary for her2 positive?
Many studies have shown that these treatments dramatically improve survival for women with HER2-positive breast cancer. Trastuzumab and chemotherapy are even recommended for women with very small, HER2-positive breast cancers. Tumors as small as 0.5 cm often warrant such treatment.
What foods should her2 positive avoid?
Foods to avoid if you have HER2-positive breast cancerSugary foods include refined or simple carbohydrates or starches. … Eating too many saturated fats can raise your cholesterol levels. … A 2014 study found that a high-fat diet is strongly linked to HER2-positive breast cancer.
What is the most aggressive type of breast cancer?
The most aggressive breast cancers include: Triple-negative breast cancer: This type of breast cancer tests negative for the hormones estrogen and progesterone, and the protein HER2. Inflammatory breast cancer: This rare form of cancer is named because it causes breast swelling and redness.
What causes her2 positive cancer?
In about 25 percent of breast cancers, the cancer cells have an excess of the HER2 protein. This is caused by a mutation in the HER2 (human epidermal growth factor receptor 2) gene. When the HER2 gene mutates, it causes cells in the breast to grow and divide at an uncontrolled rate, leading to tumor growth.
How fast does her2 positive grow?
Daily growth rate based on type was: 1.003 percent per day increase for triple negative tumors. 0.859 percent per day for HER2 positive/estrogen receptor negative tumors. 0.208 percent per day increase for estrogen receptor-positive tumors2
Where does her2 positive breast cancer come back?
Two studies found that even small (1 cm or smaller), early-stage, HER2-positive breast cancers are more likely to come back (recur) and spread to parts of the body away from the breast (metastasize) than small, early-stage, HER2-negative breast cancers.
Is her2 positive good or bad?
About 25% of breast cancers are HER2-positive. HER2-positive cancers are a mix of good and bad news. The bad news is the tumors tend to grow more aggressively than those without the HER2 receptor. The good news is that like ER/PR-positive cancers, medicines can switch the HER2 growth receptor off.
What does her2 +++ mean?
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.
