Misconceptions Many people have a misconception that breast cancer occurs only when breast lumps appear first. Fact In fact, breast lumps are only a common symptom of breast cancer. Most cancers are not really early stage cancers anymore, but are a sign of some progress. On average, it takes about 2-3 years for a breast cancer lump to develop to a size that can be felt. However, during these two to three years, there are many ways to detect the cancer instead of waiting for the cancer to grow slowly and feel it before seeking treatment. Current Status of Breast Cancer Breast cancer is a common malignant tumor in women and is currently the leading killer of women’s health in major cities. Although the number of breast cancer cases is increasing, the current treatment effect of breast cancer is relatively satisfactory, mainly due to the concept of integrated treatment combining surgery, chemotherapy, radiotherapy and biological targeted therapy. Early detection, diagnosis and treatment is the most direct and fundamental way to improve the outcome of breast cancer. Most of the ductal carcinomas in situ cannot be felt at all and need high frequency X-ray or ultrasound examination to be detected. 99% of these carcinomas can be cured clinically after treatment. The health of women is related to the harmony of family and society. The incidence of breast cancer is increasing, but we should detect breast cancer earlier and should find more breast cancers that cannot be felt as lumps, instead of waiting until a lump is found before going to the hospital. Conventional screening methods Every screening method has its suitable people and limitations, only a good combination of applications can detect breast cancer earlier. High-frequency mammography: It can significantly increase the detection rate of early breast cancer, and its radiation is extremely low, especially suitable for women over 40 years old. For young women under the age of 40, there is no need for too frequent mammograms; however, when a highly suspicious malignant lesion is encountered, continuous examinations for a certain period of time are necessary. Ultrasonography: easy, quick, non-invasive, non-damaging, repeatable, and of higher value in younger women with denser breast tissue. It is suitable for women of all age groups and different physiological cycles, especially for oriental women and young women. There are also breast ductoscopy and MRI for different conditions. Although there are many screening tools for the breast, they cannot replace each other, but only complement each other. If a lesion is found that cannot be felt as a lump, how can it be further diagnosed or treated? Indeed, in the past, surgeons relied more on a dexterous hand, and only palpable lumps were indicated for surgery. However, advances in technology have given surgeons many more hands and eyes. Tiny lesions found on mammograms, ultrasounds, or MRI scans can be biopsied using specialized puncture devices guided by a localization system to confirm the diagnosis. Vacuum-assisted biopsy systems are now commonly used to biopsy and excise these inaccessible lesions more accurately and easily, with less trauma and no scarring to ensure the appearance of the female breast. Advances in breast imaging have overturned the previous clinical understanding of breast cancer Not all breast cancers can be palpated as a lump, especially early stage breast cancers. Only proactive screening or conducting mass screening, using imaging techniques such as radiographs and scans, can detect those microscopic breast cancers, and early treatment can lead to better outcomes and save more patients’ lives and families.
