For medical questions, we encourage you to review our information with your doctor.
After you find out you have cancer, or that cancer has come back, you may feel overwhelmed. The news might come as you recover from getting surgery to remove or diagnose a tumor. No matter when you get a diagnosis, you’ll have to decide what treatment to get.
When you start to consider cancer treatments, be sure to:
Your cancer care team uses information about the type of cancer and your health to guide their treatment recommendations. Depending on the type of cancer you have, there might be a limited number of treatment options or many.
Established treatment guidelines are used to figure out which options should be offered to you. These guidelines are based on research and are used all over the country. If you want to find out more about these treatment guidelines, talk to your cancer care team.
The treatment options you’re offered might be different from those presented to a person with the same or similar type of cancer as you. Some cancers have subtypes and features that might results in different treatment recommendations.
Some cancers have special features that affect their treatment and outlook. Patient factors, such as other health problems (like kidney or liver problems), can impact which options may work best.
In general, the treatment options you’re given will depend on:
You can learn more about treatment options for specific types of cancer in Cancer A to Z.
Some common ways to treat cancer are:
Sometimes treatment options include a clinical trial. A clinical trial is a study of new drugs (medicines), procedures, and other treatments in people.
Talk to your cancer care team to find out if a clinical trial is available for your type and stage of cancer. Ask how a clinical trial might affect your health outcome.
A clinical trial may be a new treatment being studied for the first time. Sometimes, a clinical trial is a treatment being tested on different types of cancer after it’s already been approved for another type of cancer. Some clinical trials might test a new combination of treatments.
There are other options to help people with cancer, too. These include:
It’s important to remember that advances in the ways to treat cancer are being made every day. New drugs and other ways to treat cancer are constantly being studied, and many are approved for use each year.
Your cancer care team will talk to you about treatments options and when treatment should start. The start of treatment might depend on how long test results take to come back. Learn more about When Treatment Should Start and Biopsy and Cytology Tests.
Often, test results can take several days to come back. During that time, your cancer care team may not have enough information to give you treatment options.
If you’re waiting for test results that might affect your treatment options, you can still ask your cancer care team questions such as:
When your cancer care team has the details about your cancer, they will talk with you about different treatment options. Members of your cancer care team, including nurses, pharmacists, and others, are involved in talking with you and teaching you about treatment.
Questions you might want to ask about these treatment options include:
Also, ask questions that address your personal concerns and situation. For example, you may want to address your religious or spiritual beliefs. Or you may need to talk to your cancer care team about your dietary restrictions. Check to see if any of these will affect your cancer treatment options.
If you’re worried about being able to get transportation to treatment, ask about where to get help. If you have trouble taking care of yourself at home, bring up these concerns with your cancer care team.
Getting answers to these kinds of questions can give you a better understanding of what to expect during treatment.
Your cancer care team will explain your treatment options. They can guide you to other trusted sources where you may be able to find additional information. However, use caution when researching cancer treatment online. Also, be wary of advice that other people may offer. Misinformation and even outright scams could be harmful.
When doing your own research, think about these important points:
Learning all you can about your cancer and your treatment options can help you make a decision that’s best for you and that you can feel good about. Learn more in Finding Cancer Information on the Internet.
You should make your treatment decision after getting all the information you need and once you’ve had time to ask questions and have them answered. This process is called informed consent and allows people to play an active role in making decisions that affect their health.
Treatment decisions may be impacted by:
Remember that you have the right to a second opinion. You can learn more in Seeking a Second Opinion.
Shared decision-making is a process where decisions about your care are made with you, rather than for you. Shared decision-making involves doctors and other members of your cancer care team working with you and your family or caregivers to make decisions together.
It's not always easy to get everyone's input, but shared decision-making can help make sure you get the right tests and treatment. It considers risks, benefits, and costs of treatment, along with any other concerns you might have. Also, it helps to make sure you get the best care.
Not everyone diagnosed with cancer will decide to get treatment right away or at all. You can choose to decline or delay treatment. But if you do, make sure you understand why. It’s normal to feel anxious and overwhelmed by the amount of information you’ve been given. Get answers to all your questions so you can clearly understand what will be most likely to happen if you get treatment or if you don’t.
You might hear things like, “Cancer treatment is worse than the cancer itself.” Getting through cancer treatment can be tough. However, not getting treatment allows some types of cancer grow unchecked. Depending on the type, untreated cancer can lead to new and worse symptoms. It can spread to other areas of the body and stop them from working properly, which can lead to serious problems like organ failure and even death.
For most types of cancer, treatment is more likely to be successful if it starts soon after diagnosis. Waiting to start until the cancer is worse can mean the treatment might not work as well.
If you or a loved one are thinking of not getting or delaying cancer treatment, talk with your cancer care team. It might also help to talk to someone who has been treated for the same type of cancer you have. Look for local or online support groups or join a cancer survivor community to connect with others.
After learning about treatment options and making a decision, keep communicating with your cancer care team. Ask questions as they come up.
