It can also help determine if cancer has spread. CT scans use x-rays and a computer to create images of internal organs. They are most useful for identifying cancers that have spread beyond the anus.
Surgery is a common treatment option for anal cancer. A polyp is a small growth that develops on the anus. Polyps are caused by infection, injury, or overgrowth of normal cells. A doctor may remove the polyp using a surgical procedure called a polypectomy. After removing the polyp, the doctor will examine the tissue under a microscope to check for cancer cells. If the polyp is cancerous, it will need to be removed through surgery.
The most common symptoms of anal cancer include pain, discomfort, and a feeling of fullness in the anus. These symptoms may be caused by other conditions, such as haemorrhoids or tears in the anal canal. Anal cancer is often caused by the human papilloma virus. Doctors will perform a digital anorectal exam to look for tumors and take a tissue sample for analysis.
When a tumour develops, the cells in the anal area can spread through the body’s lymph fluid and bloodstream, causing secondary cancer. Most anal cancers are squamous cell carcinomas (SCCs), which develop in flat cells in the anus. Treatment for these conditions is similar to those for bowel cancer. In rare cases, adenocarcinomas of the anal area develop in glands and are treated much like SCCs in other parts of the body.
Anal cancer begins in the anus, the opening at the end of the intestine where feces exit. The tumors may be benign or malignant, depending on their location. The anus is an important part of the digestive system and is only a small part of the body. In rare cases, it may spread to other parts of the body. Symptoms include swelling and pus in the anus. If the anus is swollen, it may be cancer.
Localized anal cancer has a five-year survival rate of 80 percent. Patients with metastatic cancer have a thirty percent chance of survival after five years. The five-year survival rate for cancer near the anus is lower at 30 percent, but overall the survival rate is 66 percent. Treatment for cancer in this area depends on the stage of the cancer and the location of the tumor. The survival rate for patients with anal cancer varies greatly, but in general, treatment options are more effective than chemotherapy or surgery.
There are other possible causes of cancer near the anus, including other types of infection. HPV infection is a leading cause of cervical cancer before the Pap smear. Vaccination with HPV can reduce your risk of anal cancer. In the meantime, regular screenings can help prevent the development of anal cancer. There are also some non-cancerous conditions that may cause symptoms of cancer near the anus, including anal warts and hemorrhoids.
