Itching in the anus in itself is not associated with oncology, but in some cases this symptom can signal the development of cancer. This was told by British doctor Deborah Lee, quoted by Express.
The doctor explained that itching can often be the result of hemorrhoids, anal fissures, parasites, irritation from eating spicy foods, increased sweating or sensitivity to hygiene products. If itching is persistent, it may indicate the development of anal cancer. Most often, this disease becomes a consequence of the human papillomavirus (HPV), and in most cases occurs in people with a high probability of contracting infections that are sexually transmitted.
Also, itching in the anus can warn of bowel cancer. In this case, frequent bowel movements or bouts of diarrhea can cause itching. Also, patients with bowel cancer may have blood in the stool, and this can lead to skin irritation in the anus, the doctor explained.
