Surgery. Doctors may take out an entire organ that has tumors, such as your appendix, or remove only part of an affected area, such as a section of your bowel.
Depending on where the tumor is, surgeons may also use an electric current to burn it off or do cryosurgery to freeze it. Another option could be radiofrequency ablation. Your surgeon will use an instrument that sends electrical energy into the tumor to kill cancer cells.
Chemotherapy. Strong medicines can often kill your cancer cells or slow their growth. Some of these drugs are taken by mouth and others are injected into a vein.
Radiation. This treatment can destroy cancer cells or keep them from multiplying. The radiation can come from a machine outside your body, or your doctor may place a small amount of radioactive material inside your body, in or near the tumor.
Biologic drugs. This type of treatment, which is also called immunotherapy, strengthens your body's defense system. Doctors inject drugs into your body that help your immune system kill cancer cells.
Drug therapy. Injected drugs such as lanreotide, octreotide, and pasireotide can help with skin flushing. They may also have a small effect on stopping tumor growth. Octreotide can ease diarrhea, too.
These work by attaching to carcinoid cells and cutting down on the amount of chemicals they make. Their side effects can include nausea, gallstones, and pain or bruising where you inject it.
In some cases, doctors give octreotide with a low-dose injection of a man-made protein called alpha interferon to boost your body's response.
Taking Care of Yourself
You can make changes on your own to curb the effects of carcinoid syndrome. For instance, avoid certain foods and drinks that can trigger symptoms:
You might need to do some trial and error to see which are triggers for you.
Your intestines could have trouble absorbing nutrients, which can lead to weight loss, weakness, and other problems. Try to eat a healthy diet, and ask your doctor if you need to take vitamins or supplements.
