Breast cancer screening shows “false negatives”, ultrasound improves correct diagnosis rate
A 35-year-old young woman heard that her colleague was diagnosed with stage three breast cancer and she had never had a breast examination, so she went to the outpatient clinic to arrange a breast screening. After a breast ultrasound, it was discovered that there was a suspicious lesion of about 1 cm in size on the outer upper part of the left breast, and there was also a suspicious lesion in the left axillary lymph that was suspected to be metastasis. After pathological biopsy and imaging examination of other organs prone to metastasis, Confirmed to be stage II hormone-positive target-negative breast cancer.
Breast cancer metastasizes faster in younger people
In Europe and the United States, some people define young breast cancer as being diagnosed under the age of 40. Huang Xinghua, Director of the Breast Surgery Department of Enzhu Gong Hospital, said that the cancer cells of young breast cancer are more active and are not only highly resistant to external treatments, but also easy to metastasize. Therefore, through Regular screening, early detection and treatment are even more important. Most breast cancer patients are women, but a very small number of men may also suffer from breast cancer.
In recent years, the number of women under the age of 40 suffering from breast cancer has increased. Dr. Huang Xinghua mentioned that there are no obvious symptoms or pain in the early stages of breast cancer. It is usually discovered because there is a lump in the breast, and there may even be obvious changes in the appearance of the breast, such as wounds that are difficult to heal and skin ulcers. At this time, it may have progressed to In the middle and late stages, treatment is more difficult, so preventive regular check-ups are very important.
Regular breast screening has high initial cure rate
The National Health Service provides free mammography examinations every two years for those who are over 45 years old or over 40 years old and have a family history of breast cancer in second-degree relatives (such as mother, sister, grandmother, etc.), but some women have densely distributed breasts. For dense breasts, tumor tissue may be blocked by the dense breasts under X-ray imaging, affecting the examination results and causing “false negatives”.
Dr. Huang Xinghua suggested that in addition to mammography, breast ultrasound examination can be used to improve the correct diagnosis rate during regular physical examinations. Adult women under 40 years old are not suitable to use mammography as the first screening tool, so they can choose Breast ultrasound is not only a non-invasive examination, but also has no radiation. It can display the lesions and subdivide them into fibrocysts, blisters or tumor tissue, improving the correct diagnosis rate of early breast cancer.
