In the United States, 2,360 men are diagnosed with breast cancer and 430 men die of breast cancer each year. Considering the population base of China, how many men suffer from breast cancer in our great country every year according to the proportion. And with the imbalance of the gender ratio of China’s population, the number of men is soaring, men should not only care about the lower body, the upper body crisis is already invading! The incidence of breast cancer in men is 1/1000 (1/8 for women); there have been more than 13,000 men diagnosed with breast cancer in the United States. Although the incidence of breast cancer is lower in men than in women, once men are diagnosed, their disease will be more severe, with larger lumps, faster metastasis, worse prognosis and lower survival rates. A 2010 study by Eileen Thomas noted that about 80% of men are unaware of breast cancer in men, and most men are unaware of signs and symptoms of breast cancer other than breast lumps. Etiology Before puberty, breast tissue is similar in both sexes, only when puberty comes, the female breast starts to develop under the effect of estrogen and progesterone, and then the gap between it and male breast becomes bigger and bigger. Therefore, men do have breast tissue, just not as plump as women. Therefore, men can get breast cancer too! Men can get breast cancer too! Men can get breast cancer too!!! Ductal carcinoma predominates in male breast cancer, with lobular carcinoma accounting for only 2%. However, it is not yet known what causes men to develop such an unspeakable disease, but there are some risk factors for the disease that do not differ between the two sexes. 1. Age The risk of breast cancer increases with age. The average age of diagnosis of breast cancer in men is 68 years old. Don’t think 68 years old is far away, there is a trend of younger breast cancer nowadays, and the data represents the past. 2. family history. 3. BRCA1, BRCA2 mutation BRCA1 mutation will be the risk of breast cancer in this lifetime is 1%. 4. Cranfelt syndrome (an extra X chromosome in men). 5. Other. Obesity, smoking, excessive alcohol consumption, and physical factors that increase the risk of breast cancer in women have the same effect on men. Physical signs Men should pay as much attention to their breasts as women do. For men, the most common signs of breast cancer are swelling or lumps in the breast or lymph node area, skin crinkling and dimpling, nipple invagination, nipple discharge, and redness of the nipple or breast skin. It is worth mentioning that when men present with breast development, signs similar to breast cancer can also be seen. Regardless, men who develop abnormalities in the breast or lymph node area should seek immediate medical attention. As a random note, often feeling your chest and armpits can lead to early detection of abnormalities and thus early diagnosis and treatment. Diagnosis First physical examination of the breast and axillary lymph nodes, and then breast imaging (mammography) if there is an abnormality; breast ultrasound will also be performed before taking a biopsy will MRI for localization. All of this can make men feel unusually embarrassed. However, for high-risk groups, such as those carrying the BRCA mutation gene, breast cancer screening should be performed: semi-annual or annual screening from the age of 35; mammograms should be added to routine screening after the age of 40. Treatment There is no gender difference in the treatment of breast cancer. Mastectomy is the main treatment, supplemented by chemotherapy, radiotherapy, endocrine therapy and targeted therapy according to the specific situation. The low incidence of breast cancer in men has led to a lack of clinical research specifically on men, with the majority of data coming from studies on women, and diagnosis and treatment being based on female data, although one study on men mentioned a male breast cancer-related gene, RAD51B. For women, breast cancer is a serious, high priority disease, but that does not mean that men can ignore it. Men, join women in defending our breasts!
