Good nutrition is important, especially if you have cancer. The challenge for many is that chemotherapy can wreak havoc on your ability to eat. Common side effects of chemo include mouth sores, nausea and loss of appetite. Chemo can also temporarily damage taste buds causing foods to taste metallic or cardboard-like.
The inability to eat, for whatever reason, can lead to malnutrition. When cancer patients become malnourished, they can feel weak or tired and may be unable to receive the treatments they need to get better.
