Understanding HER2-Positive Breast Cancer
Breast cancer is a condition that affects millions of women around the world. While there are many different types of breast cancer, one of the most common is HER2-positive breast cancer. HER2-positive breast cancer is a type of cancer that affects the cells that produce the protein HER2, which helps regulate the growth of cells. About 15% to 20% of all breast cancer tumors have higher levels of this protein.
What is HER2-Positive Breast Cancer?
HER2-positive breast cancer is a type of cancer that is caused by an overproduction of the HER2 protein. This protein is found in all cells, but in HER2-positive breast cancer, it is produced in excess. This can cause the cells to grow and divide at an abnormally rapid rate, leading to the formation of tumors.
Who is at Risk for HER2-Positive Breast Cancer?
Anyone can develop HER2-positive breast cancer, but there are certain factors that can increase a person’s risk. These include having a family history of breast cancer, being over the age of 40, and having a history of chest radiation. Additionally, women who have had breast cancer before are at an increased risk for developing HER2-positive breast cancer.
Diagnosis and Treatment of HER2-Positive Breast Cancer
HER2-positive breast cancer is typically diagnosed through a mammogram or ultrasound. Once the cancer has been detected, a doctor may order additional tests to determine the stage of the cancer. Treatment of HER2-positive breast cancer typically includes surgery, chemotherapy, radiation, and/or targeted therapies. Treatments for this specific type tend to be very effective. Depending on the stage of the cancer, one or more of these treatments may be used.
Living with HER2-Positive Breast Cancer
Living with HER2-positive breast cancer can be difficult, but there are many resources available to help. It is important to talk to your doctor about your treatment plan and any questions or concerns you may have. Additionally, there are support groups and online communities that can provide emotional support and help you connect with others who have been diagnosed with HER2-positive breast cancer.
