No. There is no relationship between hemorrhoids and cancer. However, the symptoms of hemorrhoids, particularly bleeding, are similar to those of colorectal cancer and other diseases of the digestive system. Therefore, it is important that all symptom are investigated by a physician specially trained in treating diseases of the colon and rectum. Do not rely on over-the-counter medications or other self-treatments. See a colorectal surgeon first so your symptoms can be properly evaluated and effective treatment prescribed.
