Cancer treatment myths: Any truth to these common beliefs?

Myth: Everyone who has cancer has to have treatment

Truth: It's up to you whether you want to treat your cancer. You can decide this after consulting with your doctor and learning about your options.

A person who has cancer might choose to forgo treatment if he or she has:

  • A slow-growing cancer. Some people who have cancer might not have any signs or symptoms. Lab tests might reveal that the cancer is growing very slowly. These people might choose to wait and watch the cancer. If it suddenly begins growing more quickly, treatment is always an option.
  • Other medical conditions. If you have other significant illnesses, you may choose not to treat your cancer, as the cancer may not be the biggest threat to your health. This may be especially true in the case of a slow-growing cancer.
  • A late-stage cancer. If the burden of treatment side effects outweighs the benefit that treatment can bring, you might choose not to be treated. But that doesn't mean your doctor will abandon you. Your doctor can still provide comfort measures, such as pain relief.
