When it comes to the relationship between cancer and survival, we have to mention the "5-year survival rate". It refers to the proportion of cancer patients who survive for more than 5 years after comprehensive **. Why look at the 5-year survival rate? Because about 90% of tumors and metastases occur within 5 years, if there is no metastasis within 5 years, the probability of metastasis in the future is much smaller. This is a good indicator of efficacy.
Due to the development of modern medicine, the 5-year survival rate of breast cancer is getting higher and higher. Of course, breast cancer is not only physically traumatic, but more serious is the psychological trauma caused by the loss of a second characteristic that women are proud of, which may not be measured by clinical data.
Early detection, early diagnosis and examination of breast cancer.
1. Mammography examination.
Mammography is the most important means of breast cancer screening, and it is also the first choice and the most simple and non-invasive detection method for diagnosing breast diseases. Not only can it diagnose benign and malignant tumors, but it can also help doctors detect lumps that are not detected by early clinical examination.
Mammography of breast cancer can be divided into two categories: direct signs and indirect signs: direct signs include: localized masses, clusters of microcalcifications, localized dense invasions, distorted breast structure, asymmetry of both breasts, etc. Indirect signs include:**Thickening or retraction, nipple and areola abnormalities, peritumoral edema, abnormally thickened blood vessels, etc.
2. B-ultrasound examination.
Ultrasound examination is also one of the important examination methods for breast cancer, which can determine the size, location, shape and boundary of the mass, and whether the tumor is solid or cystic. It can compensate for the insensitivity of mammography to dense breast masses or deep masses and cystic masses.
The accuracy rate of B-ultrasound for breast cancer can reach 80%-85%, and the accuracy of Doppler blood flow map can reach 95%. And it is not affected by age and physiological state, and can be checked repeatedly; Suspicious tumors can be located or needle biopsied, and the diameter of the tumor can be specifically determined, which is convenient for clinical staging, surgical plan formulation and prognosis evaluation, and has been listed as a routine examination for breast diseases.
3. Breast self-examination.
Breast cancer self-screening should be done once a month, the best time is 7-10 days after the end of the menstrual cycle, and women who have stopped menstruation can choose to have a fixed time every month for self-examination.
The normalization of breast cancer is a comprehensive combination of surgery.
Surgery plays an important role in the diagnosis and development of breast cancer. With the deepening of research, the scope of resection of breast cancer surgery is getting smaller and smaller, and the range of indications for breast-conserving surgery is widening. With the development of technology and sentinel lymph node biopsy technology, it is also possible to know whether the patient's axillary lymph nodes have metastasis in advance, and patients without metastasis can be exempted from axillary lymph node dissection to reduce surgical trauma. At the same time, combined with chemoradiotherapy, endocrine and other adjuvants**, the disease can be controlled as much as possible.
Relationship between breast cancer survival and tumor stage.
As we all know, the more advanced the tumor, the lower the survival rate. Traditionally, cancer stages are 0, i, ii, iii, and iv. The 5-year survival rate of stage 0 I breast cancer can reach more than 90%, and the 10-year survival rate can reach more than 85%.
Thereafter, as the stage increases, the survival rate gradually decreases. When it comes to stage IV, there is generally a distant metastasis, and although the situation is not optimistic, the 5-year survival rate can reach about 25% after a positive **.
You can also see how important early detection is, and most of them almost meet clinical criteria for healing. But even if you find it late, don't give up**, there's always hope.
*Required to be combined.
After the diagnosis of breast cancer is confirmed, surgery is first considered if it is a patient with advanced or advanced stage. There are now breast cancer surgeries, and most people advocate modified surgeries, which are to remove the tumour while preserving its morphology to reduce the psychological impact on the patient.
Chemotherapy or radiotherapy: After breast cancer surgery, according to the pathological analysis, combined with the status of lymph node metastasis, as well as the status of hormone receptors ER, PR, or HER-2, decide whether to do the next step of chemotherapy or radiotherapy. If the HER-2 is (3+) or more, Herceptin anti-HER-2** is indicated. The ultimate goal is to increase local control and reduce distant ** and metastasis.
