A specialized medical practitioner known as an oncologist is dedicated to diagnosing and treating individuals facing cancer.
An oncologist formulates a comprehensive treatment strategy for cancer patients by analyzing detailed pathology reports. These reports provide crucial information about the specific type of cancer, its stage of development, its potential rate of spread, and the affected areas of the body.
Given that cancer treatment often involves a combination of therapeutic approaches, patients may consult with various types of oncologists throughout their treatment.
To become oncologists, individuals undergo a structured educational path. Initially, they attain a bachelor's degree, followed by four years of medical school leading to the Doctor of Medicine (M.D.) or Doctor of Osteopathy (D.O.) degree.
Upon completing medical school, aspiring oncologists embark on postgraduate medical education, engaging in internships and a residency program in internal medicine. This phase involves about three years of supervised, paid work, as outlined by the American College of Physicians.
Subsequently, oncologists receive comprehensive training across various facets of oncology during a two to three-year fellowship. Some may choose to specialize further in specific cancer types, like prostate cancer, lung cancer, breast cancer, leukemia, or lymphoma.
According to regulations set by the American Medical Association, all medical doctors in the United States must be licensed across states. This necessitates graduation from an accredited medical school. Subsequently, they must complete the United States Medical Licensing Examination.
What does an oncologist do?
Oncology, the study of cancer, is a specialized field where oncologists play a pivotal role in guiding and treating patients throughout their cancer journey. This involves several key responsibilities:
- Confirming the initial diagnosis of a patient
- Communicating the cancer diagnosis and its stage
- Presenting various treatment options and providing recommendations
- Overseeing the entire treatment process
- Assisting patients in managing symptoms and side effects associated with both the disease and the chosen treatment plan
Which types of oncologists should you consult during your cancer care?
When beginning your cancer care journey, you may consult various oncologists, each specializing in distinct aspects of treatment. Here are key categories of oncologists who play crucial roles in managing and addressing different facets of cancer:
- Medical oncologists: Medical oncologists specialize in cancer treatment through various methods, such as chemotherapy, hormonal therapies, biological therapies, and targeted treatments. They are often considered primary cancer doctors. They assist patients in managing side effects, monitor well-being, and frequently conduct follow-ups post-treatment.
- Radiation oncologists: Utilizing high-energy photon beams, radiation oncologists target and eliminate cancer cells. Around half of all cancer patients receive radiation treatments as part of their care. Techniques range from implanting irradiated material in specific areas to precise and intense radiation beams, often called radiosurgery.
- Surgical oncologists: Often among the first specialists to assess suspected cancer cases, surgical oncologists perform biopsies to examine tissue for cancer cells. If cancer is detected, patients may return for tumor removal and related procedures. These surgeons guide patients through preparation and recovery during cancer treatment.
- Pediatric oncologists: These specialists focus on diagnosing and treating cancer in children; pediatric oncologists address the unique challenges of childhood cancer, with about 175,000 children under 15 diagnosed globally each year. The oncologist may specialize in specific cancers or contribute to childhood cancer research while providing vital education and support to families.
- Gynecologic oncologists: Specializing in cancers affecting women, such as ovarian, cervical, uterine, vaginal, and vulvar cancers, gynecologic oncologists also handle non-cancerous gynecological conditions like endometriosis and fibroid tumors. The training is tailored to address the complexities of cancers specific to women.
- Hematologist-oncologist: Doctors specializing in blood cancers like leukemia and lymphoma and hematologists-oncologists may also treat non-cancerous blood conditions, including hemophilia and sickle cell anemia. The extensive training focuses on treating cancerous and non-cancerous conditions related to the blood.
What types of examinations and tests are conducted by oncologists?
When you visit an oncologist near you, they typically perform thorough physical examinations to identify any abnormalities that may indicate cancer. Additionally, they may utilize blood and urine tests and advanced imaging scans such as MRIs, ultrasounds, and C.T. scans. Biopsies involving the extraction and examination of tissue samples are also commonly performed to conclusively check for the presence of cancer cells in specific tissues.
How do cancer cells spread to other body parts?
Cancer cells can migrate from their original tumor site to other body regions primarily through two main pathways: the blood vessels or the lymphatic system. (The lymphatic system consists of vessels similar to blood vessels but carries clear fluid and immune cells throughout the body.)
For cancer cells to spread to other body parts, these cells must:
- Detach from the primary tumor and enter either the blood or lymphatic vessels
- Successfully bind to and penetrate vessel walls, then travel via blood or lymph to reach new organs or lymph nodes
- Adapt to survive and multiply in their new environment
- Successfully evade detection and destruction by immune system cells
When cancer cells travel via blood, they can reach various distant organs. If they move through the lymphatic system, they might settle in lymph nodes (specialized immune tissue centers about the size of beans) or spread to other organs.
Cancer can also impact the nervous system during its spread. Cancer cells can directly infiltrate nerves or release compounds that alter nerve function. When this occurs, cancer cells typically invade the nerve's outer covering (sheath) and progress either toward the skin's surface or deeper into body tissues. This process is known as perineural spread or invasion. Though most cancer cells that break free from the original tumor don't survive their journey, even a few surviving cells can establish themselves in new locations and form additional tumors. This process of cancer establishing new growth sites is called metastasis.
What is chemotherapy?
"Chemo," or chemotherapy, represents one approach in cancer treatment that utilizes medications to fight different cancer types. The field of cancer treatment includes several other medication-based strategies, such as:
- Hormone therapy: It includes medications designed to block specific hormones that certain cancers require for growth
- Immunotherapy: It includes medications that enhance your body's natural defense system to combat cancer
- Targeted therapy: It includes medications specifically developed to interfere with cancer cell growth patterns and behavior
Often, chemotherapy works as part of a comprehensive treatment plan, frequently combined with surgical procedures or radiation treatments.

Cancer statistics in Nevada
Cancer ranks as the second most common cause of death in Nevada, with more than 18 million Americans having a history of invasive cancer as of January 1, 2022, as per a report by the Centers for Disease Control and Prevention (CDC). Although the state's cancer incidence and mortality rates align with the national average, challenges persist in providing accessible cancer treatment and care, exacerbated by the concentration of the population, especially in Clark County, around Las Vegas. Nevada holds the 11th position nationally regarding the fewest practicing oncologists, highlighting potential barriers to comprehensive cancer care.
Understanding cancer risk is crucial, with age being a significant factor; 88% of U.S. cancer diagnoses occur in individuals aged 50 or older. Modifiable factors, such as behaviors and lifestyle choices, also contribute to increased risk in Nevada, where fundamental factors include overweight/obesity (26.7%), smoking/tobacco use (17.5%), and living in poverty (15.2%). Efforts to enhance cancer screening rates, outlined in the Nevada Cancer Plan 2021-2025, are critical. As of 2018, screening rates were reported at 66.4% (breast), 78.9% (cervical), and 60.6% (colorectal), underscoring the need for continued initiatives to promote early detection and improve overall cancer outcomes in the state.
