Colorectal Cancer Prognosis: An Overview
People facing
colorectal cancer are naturally concerned about what the future holds. Understanding colorectal cancer and what to expect can help patients and their loved ones:
- Plan treatment
- Think about lifestyle changes
- Make decisions about their quality of life and finances.
Many patients want to know their colorectal cancer prognosis. They may ask their doctor or search for statistics on their own.
A prognosis gives an idea of the likely course and outcome of a disease -- that is, the chance that a patient will recover or have a recurrence (return of the cancer).
Factors Affecting the Colorectal Cancer Prognosis
Many factors affect a person's colorectal cancer prognosis. Some of the most important factors are the type and location of the colorectal cancer and the stage of the disease (the extent to which the cancer has metastasized, or spread).
Other factors that may also affect the colorectal cancer prognosis include the person's:
- Age
- General health
- Response to treatment.
When doctors consider a person's colorectal cancer prognosis, they carefully weigh all the factors that could affect that person's disease and treatment, and then try to predict what might happen. The doctor bases the prognosis on information researchers have collected over many years about hundreds or even thousands of people with cancer. When possible, the doctor uses statistics based on groups of people whose situations are most similar to that of an individual patient.
The doctor may speak of a favorable colorectal cancer prognosis if the cancer is likely to respond well to treatment. The colorectal cancer prognosis may be unfavorable if the cancer is likely to be difficult to control. It is important to keep in mind, however, that a colorectal cancer prognosis is only a prediction. The doctor cannot be absolutely certain about the outcome for a particular patient.
