Treatment follow-up
Many patients who have completed a course of therapy for cancer also face a certain risk of cancer relapse.
- Most cancers relapse within the first five years (especially the first two to three years) and are considered cured if relapse has not occurred.
- However, some cancers can relapse late, beyond five years, such as breast cancer.
- In fact, in patients with hormone receptor-positive breast cancer, 50% of relapses happen after five years.
The risk of relapse often puts a patient in an anxious state, worrying when and where the cancer is going to come back.
- Many types of cancer follow a pattern of relapse, but some (such as melanoma) follows no pattern.
- There are blood tests (tumor markers) that may be used for regular follow-up for certain cancers (such as ovarian cancer, testicular cancer, and prostate cancer), but effective monitoring tools are still lacking for most cancers for effective monitoring.
