What is an oncology nurse?

Oncology nurses are registered nurses who take care of either cancer patients or those with the potential of developing cancer. Oncology nurses work with physicians and other medical professionals to prevent, diagnose, treat, and manage cancer symptoms, as well as provide palliative care. 

In addition to administering medical care to cancer patients, oncology nurses also provide emotional support and companionship to them. In some cases, they also educate patients on cancer terminology, symptoms, and how to live a healthy lifestyle while undergoing treatment.    

You can consider a variety of specializations within the field of oncology nursing. Some common specializations include:

• Pediatric oncology

• Radiation oncology

• Surgical oncology

• Immunotherapy

• Genetic counseling

• Hematology

Like many other health care professionals, oncology nurses earn a higher-than-average salary and have a positive job outlook.

According to the US Bureau of Labor Statistics (BLS), registered nurses earn a median annual salary of $86,070 a year [1]. Glassdoor, furthermore, estimates the average base pay of an oncology nurse to be $97,395 as of November 2024 [2]. Both of these pays are significantly higher than the total median annual salary for all workers in the United States, which the BLS notes was $48,060 as of May 2023 [3].

While the BLS doesn’t report official statistics on the job outlook for oncology nurses specifically, the profession will likely have an increasing demand in the coming years.

According to the US BLS, for example, the number of jobs for registered nurses is expected to grow by 6 percent between 2023 and 2033, resulting in approximately 194,50 new job openings every year throughout the decade [3]. The National Cancer Institute, meanwhile, reports that in 2022, the number of cancer cases diagnosed was 20 million, a number expected to rise to 29.9 million new cases every year by 2040 [4].

How to become an oncology nurse

To become an oncology nurse, you must first become a registered nurse. Once you've achieved this, you can advance your career through training, education, experience, and various certifications. 

1. Earn your nursing degree or diploma.

Every oncology nurse must first start as a registered nurse. That means you'll need to earn an associate degree (ADN), a bachelor's degree (BSN), or a nursing diploma. While each of these paths will prepare you for the profession, keep in mind that a bachelor's degree is increasingly becoming the standard for nurses, and many employers may prefer applicants with it.

2. Take and pass the NCLEX.

Once you've obtained your nursing degree or diploma, you will qualify for the National Council Licensure Examination (NCLEX), which you must take and pass to practice professionally.

Once you've passed the NCLEX, you must then become licensed by the state in which you will practice. Keep in mind, though, that each state has its own requirements, so make sure you have completed each before trying to get licensed.

3. Gain work experience.

Once you become a registered nurse, you'll likely need to gain some clinical experience before becoming an oncology nurse. Typically, it's recommended that you gain two to three years of experience before specializing in a subfield such as oncology.

During this time, it's particularly beneficial if you gain experience working with cancer patients. You should also explore other specialties within the field, such as pediatric oncology or surgical oncology, to see if you prefer a specific population or patient type.

4. Hone your skills.

Being an oncology nurse can be one of the most emotionally rewarding and challenging jobs in health care. To perform your job well, you'll need to pair medical expertise with emotional intelligence in order to best help patients suffering from some of the most critical health conditions.

Some of the people skills you should work on honing include:

• Communication: Communication is an essential aspect of most jobs that involve working with patients, but as an oncology nurse, you'll need to take it to the next level. You'll need to find ways to connect with patients emotionally and look for nonverbal signs to figure out what someone isn't telling you about their mental or physical state.  

• Empathy: Empathy and compassion allow you to put yourself in the shoes of your patients and their loved ones and make decisions based on what you'd want for your health.   

• Collaboration: As an oncology nurse, you're part of a team that includes your patients, their loved ones, physicians, therapists, surgeons, nursing assistants, and countless other health care workers. Working together to develop the best options for those patients can be the key to a positive outcome. 

5. Consider certification.

Certification is not required in every state or even for all nursing jobs that work with cancer patients. Nonetheless, gaining certification in the field can help you specialize in a specific area and make you more competitive with potential employers.

Once you have gained some experience, for example, you can earn a certification from the Oncology Nursing Certification Corporation. Some certifications you may consider include:  

• Oncology Certified Nurse (OCN): A broad certification focused on oncology nursing for adults 

• Certified Pediatric Hematology-Oncology Nurse (CPHON): A certification focused on providing oncology nursing care for children with hematological cancers like lymphoma or leukemia

• Certified Breast Care Nurse (CBCN): A certification that focuses on the prevention and treatment of breast cancer

• Blood and Marrow Transplant Certified Nurse (BMTCN): A certification focused on using blood and bone marrow transplants to treat certain kinds of cancers, including hemophilia, leukemia, and some solid-tumor cancers

• Advanced Oncology Certified Nurse Practitioner (AOCNP): A certification designed for nurse practitioners who work in general oncology

• Advanced Oncology Certified Clinical Nurse Specialist (AOCNS): A certification for advanced oncology nurses caring for patients with advanced cancers

• Certified Pediatric Oncology Nurse (CPON): A certification for oncology nurses with specialized knowledge of and experience in caring for children with cancer 

• Advanced Oncology Certified Nurse (AOCN): A certification for oncology nurses with advanced experience and specialized knowledge in providing advanced-level care for adult cancer patients

Looking to advance further?

Should you choose to advance your career as an oncology nurse even further, you might consider earning a master's degree in nursing. This can help you become an oncology nurse practitioner.

Once you graduate, you'll need to pass a national exam, and you may consider getting the AOCNP certification. Oncology nurse practitioners have more advanced responsibilities in a health care setting, such as the ability to prescribe medication and provide primary care.
