Five symptoms of early breast cancer
1. Breast lump A hard lump or lump in the breast is the most common early symptoms of breast cancer. This type of lump may appear in any part of the breast, but is usually most common in the upper outer quadrant of the breast. The lump may be painless or accompanied by pain, and it grows rapidly with unclear boundaries.
2. Changes in breast skin: Breast skin may appear thicker, reddened, wrinkled, inverted or sunken nipples, and other changes. These changes may be caused by the growth and diffusion of breast cancer cells in the breast, such as orange peel transformation, which is one of the late manifestations.
3. Nipple discharge during non pregnancy and lactation may be the early symptom of breast cancer. Overflow may be blood, fluid, breast milk, or pus, and is usually unilateral. 4. Breast pain Although the vast majority of early breast cancer patients have no obvious pain feeling, some patients may have breast pain, which may be continuous or intermittent, often occurring at the same time with breast lumps or other breast changes. 5 . Axillary lymph node enlargement When breast cancer cells spread in the lymphatic system, they often first invade the axillary lymph nodes, leading to axillary lymph node enlargement. This swelling is often painless in the early stages.
preventive measures
1. Establish a good lifestyle, maintain healthy habits, adjust the pace of life, maintain a comfortable mood, and avoid long-term mental tension and stress, which has a positive effect on the prevention of breast cancer.
2. Adhere to physical exercise. Regular physical exercise, such as fast walking, jogging, swimming, etc., will help improve physical fitness, enhance immunity, and reduce the risk of breast cancer.
3. Develop a good diet habit, eat a balanced diet, eat more fresh vegetables and fruits, and reduce the intake of high fat and high calorie foods, especially pickled, smoked, baked, fried and other foods that may contain carcinogens, so as to reduce the incidence of breast cancer.
