The best time to check your breasts should be on the 9th-11th day of the month after your menstrual period, because your breasts are softer and easier to find lesions. Women who have stopped menstruating can choose any day of the month to have regular checkups. In general, it is more convenient and feasible to perform breast self-examination in the following three situations: 1. Check your breasts in the shower: especially before the shower gel is washed away, your hands are easy to move on the wet skin. Move your flat hand gently to examine each part of your breasts. Examine your left breast with your right hand and your right breast with your left hand to check for lumps, hard knots or thickening. 2.Mirror examination: Look into the mirror with both hands down at the sides of the body, then slowly lift both upper limbs up over the head and observe the morphological changes of the breasts, including the outline of the breasts, the presence of swollen parts, the presence of slight concavity of the skin or retraction of the nipples. Next, cross your arms and observe whether the bilateral breasts are symmetrical. 3.Check while lying down: Place a pillow or soft object under the shoulder blade on the side of the breast being checked while lying down. Then place the hand on the same side behind the head so that the breast tissue is spread more evenly across the chest. The flattened hand is pressed lightly against the skin and the examination is moved gradually, centered on the nipple. The examination begins at the outer top of the breast, clockwise for the right breast and counterclockwise for the left breast. Starting at the periphery of the breast, gradually move inward to the nipple. Finally, the nipple is gently squeezed between the thumb and index finger to observe if there is nipple discharge. If there is overflow, observe whether it is clarified or cloudy, yellowish, milky or bloody. Once abnormalities are detected, you should seek medical attention immediately. General Knowledge Breast cancer is one of the most common malignant tumors in women. In the past 20 years, the incidence of breast cancer has been increasing year by year, and there are obvious urban-rural differences in the incidence of breast cancer, and the high incidence areas are mainly concentrated in large coastal cities, where breast cancer has become the number one common malignant tumor among women. The peak incidence of breast cancer in China is between the ages of 40 and 60, and the incidence rate of women is about 100 times higher than that of men, so it is not that men do not get breast cancer, it is just more common in women. High risk groups If one of your mothers or sisters has had breast cancer, you are more likely to have breast cancer yourself; in addition, women whose first pregnancy is older than 35 years old and women who have never given birth; women who eat too much animal fat and are overweight after menopause; women with certain chronic breast diseases (such as ductal epithelial atypical hyperplasia, papillomatosis, etc.). Women with first menstruation before the age of 12 or menopause before the age of 55 are more likely to get breast cancer; women who apply estrogen for a long time to control menopausal symptoms have an increased risk of breast cancer after many years; patients with breast cancer on one side also have a 5-7 times higher chance of developing cancer in the opposite breast than normal people. Regular check-ups at the hospital Especially women over 40 years old and those at high risk as mentioned above should go to the hospital for check-ups at least once a year. If you are a breast cancer patient, regular review at the hospital is also a must after standard comprehensive treatment. In addition to physical examination by your doctor, you can also be examined by auxiliary means such as ultrasound, mammography, MRI and isotope scan.
