You can drink dandelion water for breast cancer. Dandelion is a beneficial plant that may have certain anti-viral, antipyretic and detoxifying effects and can be used to prevent tonsillitis or colds. Breast cancer patients can use it as a regular health drink and take dandelion water, but they cannot rely on drinking dandelion water to treat breast cancer or prevent its recurrence. Breast cancer is a systemic disease that is more prevalent in women, but in very few men it may also occur. Breast cancer is treated with a comprehensive treatment plan based on radical surgery, including radiotherapy, chemotherapy, endocrine therapy, targeted drug therapy, etc. Other adjuvant treatments with Chinese medicine can also be considered, and drinking dandelion water can only play a health care role.
