Many lifestyle habits may also increase the risk of breast cancer, such as consuming too much high-protein and high-fat food, which can cause an increase in estrogen levels, etc. The risk of breast cancer in obese people is 1 to 1.5 times higher than that of normal-weight people, and the risk of breast cancer spreading is twice as high. If women are overweight or obese after menopause, the chance of breast cancer will increase. Breast cancer prevention: Self-examination is important, starting with a good self-examination. Regular palpation is performed by standing with fingers together and touching flat, extending the upper arm over the head to check the inner half of the breast, hanging the upper arm down to check the outer half of the breast, gradually moving clockwise from the top of the breast to check, in the order of outer upper, outer lower, inner lower, inner upper, and underarm, carefully and comprehensively checking for lumps and compressing the areola to see if there is fluid discharge, and touching the armpit and supraclavicular fossa for enlarged lymph nodes. You should also have a healthy diet and pay attention to hormone-containing foods to eat as little as possible. Also learn to release yourself and relieve stress. Do not have anxiety, such as mental factors, or learn to regulate yourself when you encounter any unexpected situation. Eliminate bad habits such as alcoholism and smoking. Take birth control pills as little as possible. Mammary gland hyperplasia is not necessarily related to the development of breast cancer. Mastocytosis occurs in most women. It is a condition of the female breast during development and is not a disease. It has no impact on life and will decrease or even disappear with age. Men can also get breast, but the probability is much lower than women. If you have breast cancer, don’t be afraid! Actively treat it and live optimistically. It can end your happy life, but it can never stop you from the relentless pursuit of happy life.
