Multiple myeloma is a cancer of plasma cells. Plasma cells are a type of white blood cell. Plasma cells make antibodies to help your body fight infection. You may have high amounts of plasma cells that do not work correctly. Your body may make so many plasma cells or antibodies that they damage your bones and other healthy tissue.

• You cannot think clearly.

Medicines:

• Medicines may be given to stop myeloid cells from growing and to kill new cancer cells. You may also be given medicine to decrease pain.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Prevent bleeding and bruising:

• Do not use sharp objects. Use an electric razor to shave. Use a nail file to keep your nails short and smooth.
• Care for your mouth. Use a soft toothbrush. Do not floss your teeth while your platelet count is low. Do not use toothpicks.
• Choose light activities. Avoid any activity that may cause chest pain or trouble breathing. Do not play contact sports, such as football or soccer.
• Blow your nose gently. Do not pick your nose. Your nose may bleed if you pick it.

Self-care:

• Wash your hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food. Avoid people who are sick and ask about other ways to help prevent infection.
• Do not smoke. Nicotine and other chemicals in cigarettes and cigars can damage blood vessels. This can make it harder to manage your symptoms. Smoking also increases your risk for new or returning cancer and delays healing after treatment. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine.
• Do not drink alcohol. Alcohol can thin your blood and make it easier to bleed.
• Drink liquids as directed. You may need to drink extra liquids to prevent dehydration. Ask how much liquid to drink each day and which liquids are best for you.
• Exercise regularly. Multiple myeloma or its treatment may make you feel tired. Exercise can help you have more energy. Ask about the best exercise plan for you.
• Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Ask about any extra nutrition you may need, such as nutrition shakes or vitamins. Tell your healthcare provider if you have problems eating, or if you are nauseated.

Follow up with your oncologist as directed:

You may need to return for more tests. Write down your questions so you remember to ask them during your visits.
