Targeted therapies are drugs that attack the parts of cancer cells that make them different from normal cells. These targeted drugs work differently from standard chemotherapy (chemo) drugs. They often have different (and less severe) side effects. For colorectal cancer, these drugs are often used to treat advanced cancers.

Some side effects seen with the targeted drugs used to treat colorectal cancer include:

  • Tiredness
  • Diarrhea
  • Headaches
  • Blood pressure problems

Some side effects are more common with certain drugs. For example, some drugs often cause a bothersome skin rash. Other drugs can cause problems with wound healing or even holes in the colon. Ask your doctor what you can expect with the drugs you will receive.

More detailed information about the targeted drugs used for colorectal cancer can be found in Colorectal Cancer.
