Oncology Nurse Job Description

An oncology nurse is one of the people a cancer patient sees most often. The oncologist chooses the regimen; the nurse checks that it is safe to give today, gives it, watches what it does, and explains to the patient and family how to get through the next week at home. That loop repeats every cycle, sometimes for years.

Before treatment. Each visit starts with an assessment: blood counts, kidney and liver values, weight, vital signs and a symptom review graded against a toxicity scale. A low neutrophil count, fresh numbness and tingling in someone receiving oxaliplatin, or a cough in someone receiving a checkpoint inhibitor goes to the oncologist before anything is hung. The nurse also confirms consent, verifies the order against the treatment plan, and completes an independent double check of drug, dose, route and pump programming with a second clinician.

During treatment. Administration covers IV infusions, subcutaneous and intramuscular injections, and oral agents that patients take at home. The ASCO/ONS Antineoplastic Therapy Administration Safety Standards, last updated in 2024, address all routes of administration for adult and pediatric patients in all settings, so a nurse teaching a patient to take an oral targeted drug is working under the same framework as one spiking a bag in an infusion chair. The nurse watches for hypersensitivity reactions, extravasation of vesicants, and with immune effector therapies, cytokine release syndrome, and keeps reaction kits and protocols within reach.

Safe handling. Many cancer drugs are hazardous to the people who prepare and give them. NIOSH's List of Hazardous Drugs in Healthcare Settings, 2024 added 25 drugs and removed 7 compared with the 2016 version, and it assists employers by identifying which approved drugs NIOSH considers hazardous. At the chairside, oncology nurses put the precautions into practice with double gloves, chemotherapy gowns, closed-system transfer devices and special disposal.

Access devices. Ports, PICCs and tunneled catheters are daily work. Confirming blood return, managing occlusions, and recognizing infection or thrombosis early are core skills, and experienced oncology nurses often become the unit's go-to for a difficult port.

Teaching and coordination. Every visit includes education: what side effects to expect, how to use antiemetics, when a fever means the emergency department, and how to care for a line. Nurses also coordinate with pharmacists, social workers, dietitians and navigators, and push back on scheduling when lab results or symptoms say a patient is not ready.

The human side. Oncology nurses get to know patients over long stretches and are present for good news, recurrences and deaths. Goals-of-care conversations, hospice referrals and grief are part of the job, and well-run units build in debriefing and peer support rather than treating that weight as a private problem.

Settings range from academic cancer centers and community hospital units to freestanding infusion suites, radiation oncology departments, bone marrow transplant programs, pediatric hematology oncology units and home infusion services.

License and degree. Oncology nursing starts with a registered nurse license, earned by completing an associate degree (ADN) or bachelor's degree (BSN) in nursing and passing the licensing exam. A BSN is generally the better long-term choice for anyone who may later want certification-heavy roles, leadership or graduate school. New graduates sometimes go straight into an oncology residency; others spend a year or two in medical-surgical nursing first to build assessment and time-management skills.

Chemotherapy and immunotherapy training. Before giving antineoplastic drugs independently, plan on a didactic course, supervised administrations with a preceptor, and employer competency validation, followed by periodic revalidation.

Oncology Certified Nurse (OCN). The core specialty credential is awarded by the Oncology Nursing Certification Corporation (ONCC). To sit for the exam, a nurse needs a current, unencumbered RN license, a minimum of two years (24 months) of RN experience and 2,000 hours of adult oncology nursing practice, both within the four years before applying, plus at least 10 contact hours of oncology continuing education. The test is three hours long with 165 multiple-choice questions, and its content outline is based on a role delineation study of basic adult oncology nursing practice completed in 2024. Practice hours can come from clinical care, administration, education, research or consultation. For a new graduate who starts in oncology, the two-year RN experience rule usually sets the timeline.

Other ONCC credentials. ONCC offers credentials for narrower practice areas:

• Certified Pediatric Hematology Oncology Nurse (CPHON)
• Transplantation and Cellular Therapy Certified Nurse (TCTCN), formerly the BMTCN, for stem cell transplant and cellular therapy nurses
• Certified Breast Care Nurse (CBCN)
• Radiation Oncology Certified Nurse (ROCN)
• Advanced Oncology Certified Nurse Practitioner (AOCNP), for nurse practitioners

Life support. Basic Life Support is standard for any bedside role, and Advanced Cardiovascular Life Support, both from the American Heart Association, is worth holding for infusion and inpatient work where reactions can turn into emergencies.

Technical skills to build:

• Central venous access device care, including port access and troubleshooting occlusions
• Infusion pump programming and independent double checks
• Toxicity grading with the NCI Common Terminology Criteria for Adverse Events (CTCAE)
• Recognition and first-line management of hypersensitivity reactions and immune-related adverse events
• Hazardous drug handling, spill response and personal protective equipment
• Oncology order sets and treatment plans in the electronic health record

Interpersonal skills. The job rewards nurses who can explain a regimen in plain language, stay steady when a patient is frightened, and say clearly to a physician that a patient should not be treated today. Comfort with serious-illness conversations and with sustained exposure to grief matters as much as any clinical skill.

The patient base is large, and the survivor population is projected to grow. The American Cancer Society's Cancer Facts & Figures 2026 projects 2,114,850 new cancer cases in the United States in 2026, excluding basal and squamous cell skin cancers. Survivorship adds a second layer: the National Cancer Institute's Office of Cancer Survivorship estimates there were 18.6 million cancer survivors in the United States as of May 2025 and projects that number will reach 22.4 million by 2035. Oncology nurses work across both groups, from first-line treatment through long-term follow-up and late-effects care.

Certification as a career marker. ONCC's 2025 Annual Report counts 33,720 Oncology Certified Nurses and 46,039 certified nurses across all of its credentials. For an individual nurse, the OCN is a portable signal of specialty knowledge that travels from one employer to the next. Whether it unlocks a clinical ladder step or a pay differential depends on the employer, so check the local policy before counting on either.

Where the work sits. Hospital oncology units, outpatient infusion centers, radiation oncology, transplant and cellular therapy programs, pediatric hematology oncology, and home infusion all employ oncology nurses. Nurses on transplant and cellular therapy units also manage cytokine release syndrome and neurotoxicity monitoring for immune effector therapies.

Adjacent roles. Experienced oncology nurses move into several positions that build on the same knowledge:

• Nurse navigator, guiding patients from diagnosis through treatment scheduling, insurance and referrals
• Clinical research nurse, managing protocol-driven treatment and toxicity reporting on trial units
• Nurse educator or professional development specialist for chemotherapy competencies
• Nurse manager or director of an infusion center or oncology service line
• Oncology nurse practitioner, after graduate education and national NP certification

Technology and AI. Nurse readiness for AI tools is an open question. A cross-sectional survey of 132 oncology nurses in the greater Houston area, published in the Clinical Journal of Oncology Nursing in August 2026, found limited AI literacy and formal education alongside strong interest in learning about and codeveloping AI tools. The hands-on core of the job, from accessing a port to stopping an infusion at the first sign of a reaction to sitting with a family after bad news, remains hands-on work that these tools do not perform. Learning to evaluate them critically, and taking part in local decisions about how they are used, is a sensible professional investment.

What to weigh. The specialty offers deep clinical expertise, long patient relationships and a clear credential path. It also asks for emotional stamina and steady study: ONS issued a 2024 drug supplement to its chemotherapy and immunotherapy guidelines to cover FDA-approved antineoplastic medications from September 2021 through May 2024. Choosing a unit with real peer support matters as much as choosing the specialty.

Dear Ms. Alvarez,

I am applying for the Infusion Center RN position at Lakeshore Cancer Institute. For the past four years I have worked on the inpatient hematology oncology unit at Riverside General, and I earned my OCN certification this spring. I am ready to bring that inpatient foundation to an outpatient setting where I can follow patients across a full course of treatment.

On my unit I care for patients admitted for induction chemotherapy, neutropenic fever, tumor lysis risk and complications of immunotherapy. That mix has made me careful about pre-treatment checks. I review counts and chemistry trends before every dose, and I have stopped more than one infusion to call the oncologist about a lab value or symptom that did not fit the plan. I also serve as a chemotherapy preceptor, which means I spend a lot of time explaining to newer nurses why we verify a pump setting twice even when the order looks routine.

Ports and PICCs are a strength. Colleagues page me when a port will not give blood return, and I have helped revise our unit's occlusion management checklist with our vascular access team.

The part of the work I value most is teaching. I keep my discharge instructions short and specific: which number to call, which temperature means the emergency department, and what to do about nausea at two in the morning. Families tell me the plain language helps.

Lakeshore's investigational therapy program and your nurse-led symptom management clinic are the reasons I am applying here rather than elsewhere. I would welcome the chance to learn your workflows and contribute from my first week.

Thank you for your time and consideration.

Sincerely, Jordan Reyes, RN, OCN
