Receiving a cancer diagnosis can be overwhelming – the sudden rush of medical jargon, tests, appointments, information, and decision-making can make your head spin. It is only natural that you have questions about what it all means for you and for your family.
You may wonder if your cancer is serious, for example, and worry if you will be okay. All of these concerns are valid, and your cancer care team will try to address them as clearly and as thoroughly as they can.
Understanding your cancer diagnosis and learning a few key medical words can help you get a better idea of what is happening and what may lie ahead.
Cancer specialists “grade” cancer according to how the cancer cell appears under a microscope; the cells can provide clues about how quickly your cancer will likely grow and spread.
Grade 1 cancer cells look similar to normal cells and are organized like normal cells; grade 3 and 4 cancer cells look quite different.
Grading systems can differ between the various types of cancer. When grading breast cancer, pathologists often use the Nottingham grading system that looks at the size and shape of the cancer cell's nucleus, and they use the Gleason scoring system that looks at the organization of cancer cells when grading prostate cancer.
An important part of treating a patient’s cancer is to first find out how far it has spread, or what “stage” it has reached.
Cancer stage is the size and/or extent to which the cancer has spread. To stage cancer, doctors consider:
Treatment often depends on the type of cancer and the extent to which it has spread. Knowing the stage helps doctors plan the appropriate type of treatment, estimate a patient’s prognosis and identify clinical trials that may be suitable.
Cancer specialists often use the TNM system to stage cancers that form solid tumors, such as breast, colon, and lung cancers. The system helps doctors describe the primary tumor where the cancer started and whether the cancer has spread, or metastasized, to other tissues and organs in the body.
TNM is an abbreviation that stands for:
Doctors combine the TNM classifications to determine the stage of cancer. Most cancers have four stages, although some types of cancer also have a fifth stage, known as Stage 0 (zero).
Staging varies, depending on the type of cancer. For example, leukemia, lymphoma, multiple myeloma, and other cancers of the blood use a different staging system since they do not form solid tumors.
If you are like most patients who have just received a cancer diagnosis, one of your first questions is, “How likely am I to beat this?” or "How serious is it?"
While cancer doctors cannot predict the future, they can make an estimate based on the experiences of other people with the same type of cancer. This is referred to as a prognosis.
Some types of cancer are more aggressive than are others, for example, and other types of cancer spread more slowly. After doctors diagnose cancer and create a treatment plan, they can often offer a prognosis, which is the most likely outcome.
Cancer specialists, known as oncologists, also use other factors to make the prognosis. Specifically, the factors affecting your prognosis include:
Cancer statistics gathered by researchers over the years provide insight into your prognosis. Doctors use statistics about people with the same cancer type, stage, and treatment to estimate your prognosis.
Your oncologist, who knows the most about your situation, is the best person to discuss your prognosis and explain what the statistics may mean.
It is important to know that a prognosis is merely a probable outcome- based on the average outcome from a sample of people with your type of cancer and other similar factors. It does not mean that your outcome will be the same.
Understanding your type of cancer and prognosis can help you and your loved ones explore the various treatment options, manage the side effects of treatment, and learn new ways of taking care of yourself.
How much you learn about your cancer diagnosis and prognosis is up to you – some people prefer to learn all they can, while others find that information confusing or frightening.
If you decide that you want to learn more, your oncologist, cancer care team, and our website are great places to start. They can provide you with reliable information, explain what the statistics mean, and discuss your prognosis.
Coping with a prognosis can be difficult, especially if you don't have a support system. If you need help managing the emotional, psychological and social challenges relating to your cancer diagnosis, contact our oncology social workers at Willamette Valley Cancer Institute. We provide one-on-one counseling and may be able to help you connect with support groups, financial aid, and other assistance you may need.
