Survivorship: During and After Treatment
Try to eat well. A healthy diet helps your body function at its best. This is even more important if you have cancer. You’ll go into treatment with reserves to help keep up your strength, your energy level, and your defenses against infection. A healthy diet can also prevent body tissue from breaking down and build new tissues. People who eat well are better able to cope with side effects of treatment. And you may even be able to handle higher doses of certain drugs. In fact, some cancer treatments work better in people who are well-nourished and are getting enough calories and protein. Try these tips:
If you can’t do any of the above during this time, don’t worry about it. Tell your cancer care team about any problems you have and ask if there is a dietician or nutritionist you could speak to. Sometimes diet changes are needed to get the extra fluids, protein, and calories you need.
During cancer treatment your body often needs extra calories and protein to help you maintain your weight and heal as quickly as possible. If you’re losing weight, snacks can help you meet those needs, keep up your strength and energy level, and help you feel better. During treatment you may have to rely on snacks that are less healthy sources of calories to meet your needs. Keep in mind that this is just for a short while – once side effects go away you can return to a healthier diet. Try these tips to make it easier to add snacks to your daily routine:
If you’re able to eat normally and maintain your weight without snacks, then don’t include them.
Meats, poultry, and fish
Beans, legumes, nuts, and seeds

Physical activity has many benefits. It helps you maintain muscle mass, strength, stamina, and bone strength. It can help reduce depression, stress, fatigue, nausea, and constipation. It can also improve your appetite. So, if you don’t already exercise, talk to your doctor about aiming for at least 150 to 300 minutes of moderate activity, like walking, each week. If your doctor approves, start small (maybe 5 to 10 minutes each day) and as you are able, work up to the goal of 300 minutes a week. Listen to your body, and rest when you need to. Do what you can when you’re up to it.
