Myth #1: Women with a family history of breast cancer are the only ones who are at risk for developing cancer. Fact: 70% of women who have been diagnosed with breast cancer have no significant risk factors for the disease. However, if a first-degree relative (including a mother, sister or daughter) has breast cancer, that person’s risk of developing breast cancer is doubled. A parent’s family history of the disease has an equally important effect on a woman. Myth #2: Wearing a bra will increase the risk of breast cancer. Fact: Many people point out that bras will compress the lymphatic system of the breast, leading to the accumulation of toxins and inducing breast cancer, a claim that has been widely proven to be unscientific. Myth 3: Breast augmentation surgery may cause breast cancer. Fact: Breast augmentation in women does not increase the risk of breast cancer. However, it is necessary for these women to add an X-ray examination of their breasts to their physical examinations. Myth 4: Breast cancer is not prevented by mastectomy. Fact: Mastectomy can reduce the chance of cancer to a great extent, but it cannot prevent it completely. Sometimes the disease may start in the scar or the existing cancer cells may spread. Myth #5: Most breast lumps are cancerous. Fact: About 80% of breast lumps are caused by benign mutations, and doctors recommend getting checked as soon as a lump occurs in the breast. Myth 6: Breast cancer always appears in the form of lumps. Fact: Lumps may indicate breast cancer, but there are more signs of the disease than that: breast or nipple pain, breast swelling, skin irritation or dimpling, nipple contraction inward, etc. Myth #7: If you have a high chance of developing the disease, you have to wait for the signs to appear. Fact: Women can be proactive in reducing the risk of breast cancer, such as maintaining weight and avoiding obesity; keeping regular exercise; reducing or eliminating alcohol intake; having regular breast health checkups; quitting smoking, etc. Myth 8: Women with small breasts have less chance of developing cancer. Fact: There is no relationship between breast size and breast cancer. Extra large breasts may only mean that they are less likely to be examined and have no relationship with the chance of cancer.
