Invasive Breast Cancer: Challenges and Hopes
Invasive breast cancer, which sounds daunting, is one of the main threats to women ‘ s health. Unlike early non-invasive breast cancer, the cancer cells of invasive breast cancer have pierced the base membrane, spreading to the surrounding tissues, with a higher degree of malignity and more difficult treatment. However, as medical technology continues to improve, significant progress has been made in the diagnosis and treatment of invasive breast cancer, which gives new hope to patients. First, the classification of invasive breast cancer is essential for the development of treatment programmes. Depending on the type of tissue, invasive breast cancer can be classified as immersive catheter cancer, immersive leaf cancer, etc. Vaccination catheters cancer is the most common type, accounting for 70 to 80 per cent of breast cancer. This type of cancer originates from the mammary catheter, and the cancer cell is immersed in the surrounding tissues after it breaks through the substrate and forms a lump. The immersion of filamental leaf cancer originates in the mammary leaf, and cancer cells spread along the mesothelican leaf to form a number of small stimuli. Secondly, according to hormonal receptor, intrusive breast cancer can be classified as hormonal receptor positive (HR+) and hormonal receptor negative (HR-). The hormonal receptor positive invasive breast cancer cells have estrogen receptor or pregnancy hormone receptor on their surface, and these cancers are sensitive to endocrine treatment and are relatively good. Invasive breast cancer of the hormonal receptor negative is not sensitive to endocrine treatment and is less predictable. In addition, according to the genetic expression of Her2, invasive breast cancer can be classified as HeR2 positive and HeR2 negative. Overexpression of HER2 protein on the surface of the ER2-positive invasive breast cancer cell is a high degree of malignity and poor prognosis, but is sensitive to HER2 treatments, such as tratophosics. HeR2 invasive breast cancer is not sensitive to such treatment. Furthermore, intrusive breast cancer can be classified into tube cavity A, tube cavity B, HeR2 concentration and base model according to molecular stratification. Invasive breast cancer type A of the tube is better prepared and sensitive to endocrinic treatments; cavity type B is more malignant and sensitive to both chemotherapy and endocrine treatments; ER2 intrusive breast cancer is more malignant and less pre-pregnant, but sensitive to HeR2 treatments; base model invasive breast cancer is less pre-pregnant and sensitive to chemotherapy but lacks effective target-oriented treatment. Understanding the classification of invasive breast cancer and its clinical significance is essential for early diagnosis and treatment. Different types of invasive breast cancer are treated in different ways and with different sensitivity to treatment, so the development of individualized treatments based on the classification of invasive breast cancer can increase the effectiveness of treatment and improve patient prognosis. In general, the diagnosis and treatment of invasive breast cancer is a complex and important subject, which relates not only to the diagnosis and treatment of breast cancer, but also to the prognosis and quality of life of patients. Let’s start with the classification of invasive breast cancer and get a better understanding of the disease and provide a scientific basis for the prevention and treatment of breast cancer.
