Breast cancer is a common malignant tumor in women, about 1.2 million women around the world suffer from breast cancer every year, and the incidence of breast cancer in China is also increasing year by year, and it has become the number one killer of women’s health in big coastal cities. However, due to the lack of awareness, there are often some misconceptions about breast cancer: Misconception 1: Only postpartum or middle-aged women need to start preventing breast cancer? The peak age of breast cancer incidence is between 40 and 60 years old. Many people think that breast cancer is a disease that is only highly prevalent in middle-aged and older women, but in fact, young women are at the same risk of breast cancer as older women. Recent studies have shown that the incidence of breast cancer among women in large cities is increasing year after year and is trending younger. In the tertiary prevention of breast cancer, the focus should be on early diagnosis and treatment, regular self-examinations, special physical examinations and medical checkups by specialists, especially for women with family history of breast cancer or those who are at high risk of breast cancer. Women over 35 should receive a mammogram every six months and a mammogram every year. Myth 2: You only need to choose between breast ultrasound and mammography? Many people think that they only need to choose one of ultrasound or mammography for breast examinations, but this is actually wrong. Color ultrasound is non-invasive, fast, repeatable, and can accurately identify cystic and solid lesions with an accuracy of 96% to 100%, while color Doppler flow imaging can identify the benign and malignant nature of breast lumps, but color ultrasound cannot detect microcalcifications. Mammography can detect breast lumps that cannot be touched by doctors, especially for large breasts and fatty breasts, its diagnostic accuracy can be as high as 95%, and its sensitivity and specificity for malignant tumors manifested by calcified foci are very strong. It is the most convenient and reliable non-invasive test for the diagnosis of breast diseases. Therefore, these two examinations are complementary and irreplaceable to each other, and they are the two necessary examinations for breast health checkup. Myth 3: Breast pain is the precursor of breast cancer, so there is no need to worry if the breast does not hurt? Many women think that breast cancer is mainly manifested by breast pain, so the first thing they worry about is whether they have breast cancer or not. In fact, the first common symptom of breast cancer is the discovery of painless lumps, while breast pain is often a common manifestation of breast enlargement. The pain of breast enlargement is usually cyclical breast pain, which can be accompanied by breast lumps and changes with menstrual cycle and emotions. But regular breast checkups are necessary for early detection of breast lesions. You cannot assume that if your breasts don’t hurt, you don’t need to worry about the occurrence of breast tumors. Myth 4: Breast cancer can only be solved by “everything”? When many people talk about the treatment of breast cancer, the first thing that comes to their mind is the removal surgery. In fact, the treatment of breast cancer is mainly a comprehensive treatment based on surgery. With the advancement of technology, surgery is no longer a blanket removal of the whole breast, but depending on the condition, breast-conserving surgery, immediate or postponed reconstruction of the breast, sentinel lymph node biopsy and other advanced surgical procedures can be chosen. Therefore, early detection is very important for tumor control. The earlier the detection, the better the treatment effect, not only curing the disease, but also obtaining a good breast appearance effect, reducing trauma, and reducing the impact on patients physiologically and psychologically.
