Because of the Taxetere and the HER-2 drug (herceptin) that I will be receiving, they are known to cause heart damage, so I need frequent heart scans to see how well (or not) it is functioning. I started out at 72%, this time I'm at 66%.
HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor-2 (HER2), which promotes the growth of cancer cells. In about one of every three breast cancers, the cancer cells make an excess of HER2 due to a gene mutation. This gene mutation can occur in many types of cancer — not only breast cancer.
HER2-positive breast cancers tend to be more aggressive than other types of breast cancer. They're also less responsive to hormone treatment. However, new treatments that specifically target HER2 are proving to be very effective.
