People sometimes use complementary therapies along with medical treatment to help relieve symptoms and side effects of cancer treatments. Some of the complementary therapies that may be helpful include:
Mind-body treatments like the ones listed above may help you feel better. They can make it easier to cope with cancer treatments. They also may reduce chronic low back pain, joint pain, headaches, and pain from treatments.
Before you try a complementary therapy, talk to your doctor about the possible value and side effects. Let your doctor know if you are already using any of these therapies. Complementary therapies are not meant to take the place of standard medical treatment. But they may improve your quality of life and help you deal with the stress and side effects of cancer treatment.
You may be interested in taking part in research studies called clinical trials. Clinical trials are based on the most up-to-date information. They are designed to find better ways to treat people who have cancer. People who don't want standard treatments or aren't cured by standard treatments may want to take part in clinical trials. These are ongoing in most parts of the United States and in some other countries around the world for all stages of colorectal cancer.
