There are different reasons why you could feel or be sick. This includes the cancer itself or its treatment. Some people can feel sick (have nausea) and not be sick. Others are sick (vomit) and never actually feel sick. You can have nausea or vomiting on it's own or both together.
There are a number of ways sickness can be managed and treated. You might have one or more anti sickness medications. And you may choose to use some complementary therapies alongside medication.
