AMBULATORY CARE:

Common signs and symptoms:
- Bleeding from your anus
- Blood or mucus in your bowel movements
- Small lumps around your anus
- Pain and itching around your anus
- Not being able to control your bowel movements
Seek care immediately if:
- You have new or worsening symptoms.
Call your doctor or oncologist if:
- You have a fever.
- Your pain is worse or does not go away after you take your pain medicine.
- You have questions or concerns about your condition or care.
Treatment:
Your healthcare provider can help you understand which treatment may be best for you:
- Chemotherapy (chemo) medicine is used to kill cancer cells. Chemo may be used to shrink the tumor or lymph nodes before surgery. Chemo may be combined with external beam radiation therapy (ERBT) for treatment called chemoradiation. This helps treat anal cancer without harming the sphincter (muscles that help hold the anus closed).
- Radiation may be used without chemo to shrink cancer cells.
- Surgery may be used to remove a small tumor or if other treatment does not work. Surgery may damage the sphincter, so other treatments may be tried first.
Treatment options
The following list of medications are related to or used in the treatment of this condition.
Manage or prevent anal cancer:
Your healthcare provider may recommend screening every 1 to 3 years if you are at high risk for anal cancer. Your provider can give you more information about screening tests. The following are general ways to prevent or manage anal cancer:
- Prevent an HPV infection. Some types of HPV increase your risk for anal cancer. HPV may be spread through sexual activity. The HPV vaccine is usually given at 11 or 12 years of age. It can be given from 9 years through 45 years of age, if needed. Use a new condom, contraceptive barrier, or dental dam each time you have sex. This includes oral, vaginal, and anal sex.
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars increase the risk for anal cancer. Ask your provider for information if you currently smoke and need help to quit. E-cigarettes and smokeless tobacco still contain nicotine. Talk to your provider before you use these products.
- Eat healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. You may need to change what you eat during treatment. Do not eat foods or drink liquids that cause gas, such as cabbage, beans, onions, or soda. A dietitian may help to plan the best meals and snacks for you.
- Be physically active as directed. Physical activity, such as exercise, may improve your energy levels and appetite. Ask about the best activity plan for you.
- Ask your provider about sex during treatment, if needed. Your provider will tell you if it is okay to have sex while the cancer is being treated. Ask about safe ways to have anal, vaginal, or oral sex during this time.
Follow up with your doctor or oncologist as directed:
You will need to see your oncologist for ongoing treatment and follow-up. Write down your questions so you remember to ask them during your visits.
