Can exercise cause breast cancer to spread?
In general, exercise does not cause the spread of breast cancer. Breast cancer is a condition in which epithelial cells in the breast undergo uncontrolled proliferation due to various carcinogenic factors; therefore, physical activity does not lead to the dissemination of breast cancer. The detailed explanation is as follows:
Breast cancer is a malignant tumor originating in the breast tissue. Its exact cause remains unclear but is usually associated with hormonal influences, genetic factors, radiation exposure, excessive stress, and other factors. Common symptoms of breast cancer include breast lumps, nipple discharge, abnormal changes in breast skin, and enlarged axillary lymph nodes. Like other malignant tumors, breast cancer primarily spreads to other organs in the body through hematogenous (blood) metastasis, lymphatic metastasis, and implantation metastasis. Hence, exercise does not contribute to the spread of breast cancer.
Patients with breast cancer can receive medication under the guidance of a physician, such as tamoxifen citrate tablets or toremifene citrate tablets. For patients with more severe disease, timely surgical intervention may be necessary, including modified radical mastectomy or extended radical mastectomy for breast cancer. Some patients may also require adjuvant treatments such as radiotherapy or chemotherapy following surgery.
If breast cancer patients experience any discomfort or unusual symptoms, they should promptly seek medical attention at a hospital to avoid delays in treatment.
