The incidence of breast cancer in men is 1/200 of that in women. This list of breast cancer in men shows that breast cancer is not a disease that only women can get, but men are not immune to it either. However, because of the small size of male breast and short lymph, cancer cells are more likely to spread quickly, so the mortality rate is higher than that of female breast cancer patients. What are the high-risk groups of male breast cancer? Breast cancer is the appearance of malignant tumor cells in the breast cells. Since men have breast tissue like women, they are naturally at risk of breast cancer. The following 5 types of people are at risk of breast cancer in men. 1. Family history of breast cancer. 2.Men between 60 and 65 years old, mainly because of aging problems. 3.Men with low testosterone. 4.People who have suffered from female breast disease or obesity. 5. The testicles have been injured or removed, or have suffered from cryptorchidism. How should men check for breast abnormalities? Men usually ignore breast hardness and will not seek treatment until they have bleeding or pus, so the same methods women use to check their breasts are also applicable to men. A. Painless lumps: Most men with breast cancer are found in the lower breast, so if you find a lump on the lower areola, you should pay attention to it, because this is the location where male breast tissue is concentrated. Abnormal nipple shape: If male nipples are sunken, crusted, or retracted, you should also pay attention to this phenomenon. Changes in the skin of the chest: If there are changes in the skin or pectoral muscle of men’s chest, such as red rash or bonding, it may be a sign of breast cancer. Nipple overflow: liquid flowing out when squeezing the nipple is called nipple overflow. According to statistics, 3% to 14% of people who visit the doctor with nipple overflow as the first symptom have breast disease, which is also one of the signs of breast cancer. Lymph nodes in the armpit: If there are lymph nodes in the armpit, it is a standard symptom of breast cancer, and usually there is more than one lymph node. Men should always pay attention to the changes of their breasts and once they find any abnormalities, they should not ignore it and should seek medical attention as early treatment has a high chance of cure.
