If you have cancer, you may get side effects from your treatment. You might also have symptoms from the cancer itself.
A short description of each symptom is given below. You will find a link to a Symptom Management Guide from Ontario Health-Cancer Care Ontario as well as extra materials to further support you.
OH-CCO has created guides to help you, and your loved ones manage your symptoms. The guides are filled with easy-to-follow tips for what you should do to help manage your symptoms. They also can help you decide when to seek help from your healthcare team.
Remember – these guides are a starting point to help you manage your symptoms. You should always let your cancer team know about changes to your health.
Anxiety is the feeling of fear, dread, or uneasiness that can happen as a result of stress.
Constipation happens when your poop becomes hard to pass. This might mean your poops are harder than normal or happen less often than normal.
Diarrhea means having loose, watery, or liquid poops.
