10 Anal Cancer Symptoms
4. Lumps in the Anus
The anus is usually smooth to the touch. Some conditions may cause the anus to develop lumps, disrupting the usual structure of the area. Anal warts are small lumps that appear in the anus and are associated with a Human Papilloma Virus (HPV) infection. Other conditions may cause small polyps to grow in the area as well. Most of the time, these lesions are associated with benign conditions. Nevertheless, it is important to get medical attention to get a proper diagnosis.
Up to 30% of patients diagnosed with anal cancer experience a sensation of rectal lump or mass at some point in their condition. This symptom is usually associated with benign conditions such as polyps or hemorrhoids, but sometimes these lumps might be a sign of anal cancer. The most important risk factor associated with anal cancer is an HPV infection, and this condition is known to cause the development of anal warts.
