The Accuracy of a Cancer Diagnosis
About 41% of men and women born in the United States today will be diagnosed with cancer at some time during their lifetime (NCI’s SEER Cancer Statistics Review).
Since every cancer and every person is different, an accurate diagnosis can mean the difference between getting and not getting the most effective treatments you need to fight the disease.
Planning Treatment through Recovery
An accurate diagnosis serves an important role through all phases of the cancer journey. Doctors use diagnostic tools to identify and locate tumors, stage the disease, and determine the best
treatment approach. These tools enable doctors to monitor the progress of treatment and modify current therapies when needed. After treatment is complete, diagnostic tools can be used to identify recurrence.
Diagnostic Tests
A cancer diagnosis is based on a combination of tests which often includes, but is not limited to, the following:
- A medical history
- Physical examination
- Laboratory tests (blood, urine, etc.)
- Imaging tests (X-ray, PET/CT, MRI, etc.)
- Nuclear medicine tests (bone scans, etc.)
- Ultrasound
- Biopsy
- Genetic tests

Challenges to an Accurate Diagnosis
To arrive at an accurate diagnosis, your doctor will need to first confirm the presence of disease, and then identify the correct tumor type, location, extent and stage. This can be challenging. For some cancers, such as metastatic tumors, it can be difficult to determine where the cancer originated.
Also, an accurate diagnosis relies greatly on proper staging to guide decisions about treatment. Let’s say a patient is initially diagnosed with a stage III tumor and is considered inoperable. After more advanced diagnostic testing, if the tumor is determined to be stage I, that same patient now becomes eligible for surgery.

Improving the Accuracy of a Diagnosis
Having direct access to advanced diagnostic technology and clinical expertise improves the accuracy of a diagnosis. Advanced technology can help pinpoint tumors and allow doctors to determine the best combination of treatments. Some diagnostic tests can identify an effective treatment approach from the start, before treatment even begins. Experienced physicians with expertise in diagnosing diseases, such as pathologists, can more precisely determine the exact cell type and grade of a tumor.

10 Tips for Receiving an Accurate Cancer Diagnosis
Get the facts about your cancer diagnosis. The more you understand about your cancer diagnosis, the better equipped you’ll be to make informed decisions about treatment. Learn about your type of cancer, its size, location and if it has spread. Find out if it’s slow-growing or aggressive. Ask your doctor for patient education materials and resources.
- Choose your cancer team carefully. Find a hospital/facility that has experts in your form of cancer and advanced technology to diagnose and treat the disease. Also, find a cancer team that includes clinicians from many different disciplines who collaborate on a regular basis to evaluate your status using advanced diagnostic tools.
- Seek individualized care. Every cancer diagnosis is unique. Even the same type of cancer can grow at different rates and respond differently to the same treatments. What works for one may not work for another. You should have access to diagnostic tools that precisely identify and pinpoint the disease so your doctor can plan the most effective treatment.
- Take an active role in the process. You can take charge of your health by working cooperatively with your cancer team and asserting your needs. Ask ahead of time about the diagnostic testing you’ll need and how you can prepare for it. Ask for test results in a timely manner. Make sure you understand next steps before leaving your doctor's office.
- Consider a second opinion. You may want to get a second or third opinion before beginning treatment. Most doctors understand the value of a second opinion when facing major decisions. A second opinion can help you feel more confident in the accuracy of your diagnosis, or, in some cases, it can reveal inaccuracies and ensure treatments better suited to your needs.
- Get the most out of your appointments. Naturally, you may find it difficult to retain all the information you receive after a cancer diagnosis. Write down the questions you want answered ahead of time. Whenever possible, bring someone with you to appointments. They can think of questions you may not have thought to ask and take notes for you.
- Ask questions about your diagnosis. An important part of dealing with your cancer diagnosis is asking questions and clarifying what you don’t understand. If your doctor uses medical terms you don’t understand, ask him or her to explain it in another way. Try repeating what you think was said back to your doctor for confirmation. Here are some questions you may decide to ask:
- What kind of diagnostic tests do I need?
- What can I expect from diagnostic testing?
- How long will it take to get the results?
- How soon can I start treatment after diagnostic testing?
- How will I know if treatment is working?
- How can I stay on top of a recurrence?
- Communicate with your doctors. Communication with your cancer team is essential to understanding your diagnosis and making informed treatment decisions. Ask about what was uncovered during the diagnostic process and the treatment options that are available to you. Find out the best way to reach your care team if you have questions from home.
- Schedule follow-up visits. Once you complete treatment, make sure to schedule the necessary follow-up visits with your cancer team. During these visits, your doctor will use diagnostic tests to identify any changes in your condition and stay on top of any metastasis or recurrence. These appointments may occur more often at first and then less frequently.
- Don’t give up. If you have been given no further options after a cancer diagnosis, it does not necessarily mean that other options don’t exist. Remember, there are other doctors that may present a different picture. Some hospitals may be able to provide more advanced technology and resources that can help you.
