Passing egg-white-like mucus from the anus may be caused by hemorrhoids, especially when hemorrhoids irritate the local rectal mucosa, leading to excessive mucus secretion. In cases of proctitis or anal sinusitis, inflammatory stimuli can cause the rectal mucosa to exude inflammatory secretions. For bacterial colitis or proctitis, anti-infective treatment is typically used, along with avoiding oily, spicy, and irritating foods; clinical symptoms usually improve within about one week. Mucus discharge can also occur in malignant intestinal tumors such as colon cancer and rectal cancer. These conditions generally require comprehensive treatment including radical surgery for colorectal cancer, postoperative chemotherapy, radiotherapy, and molecular targeted drugs.
