Do You Need to See an Oncologist for Skin Cancer?
Whether you need to see an oncologist for skin cancer depends on the type and stage of the cancer; while many cases can be successfully treated by a dermatologist or surgeon, more advanced or complex cases often require the specialized care of an oncologist.
Understanding Skin Cancer
Skin cancer is the most common form of cancer in the United States. It develops when skin cells, usually due to exposure to ultraviolet (UV) radiation from the sun or tanning beds, undergo abnormal and uncontrolled growth. There are several types of skin cancer, broadly categorized into:
- Non-melanoma skin cancers (NMSCs): These include basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). They are typically slow-growing and rarely metastasize.
- Melanoma: This is the most dangerous type of skin cancer. It develops from melanocytes, the cells that produce pigment, and can spread rapidly to other parts of the body if not detected and treated early.
- Less common skin cancers: These include Merkel cell carcinoma, cutaneous lymphoma, and Kaposi sarcoma.
The Role of Dermatologists
Dermatologists are physicians who specialize in the diagnosis and treatment of skin conditions, including skin cancer. They are often the first point of contact for people with suspicious moles or lesions. Dermatologists are skilled at:
- Performing skin examinations and biopsies.
- Diagnosing different types of skin cancer.
- Treating early-stage NMSCs with methods such as:
- Surgical excision
- Cryotherapy (freezing)
- Electrodessication and curettage (scraping and burning)
- Topical medications.
For many cases of BCC and SCC, a dermatologist can provide complete and effective treatment.
When is an Oncologist Necessary?
While dermatologists manage many skin cancers, there are situations where the expertise of an oncologist is essential. An oncologist is a physician who specializes in the diagnosis and treatment of cancer, including systemic therapies like chemotherapy, immunotherapy, and targeted therapy. An oncologist may be needed when you need to see an oncologist for skin cancer if:
- The skin cancer is melanoma: Because melanoma can spread rapidly, the involvement of an oncologist is often recommended, particularly for more advanced stages.
- The skin cancer has metastasized (spread): If the cancer has spread to nearby lymph nodes or other organs, systemic therapies administered by an oncologist become necessary.
- The skin cancer is recurrent: If skin cancer returns after initial treatment, an oncologist can help develop a plan to address the recurrence, which might involve different treatment modalities.
- The skin cancer is aggressive or high-risk: Certain types of SCC and less common skin cancers may have a higher risk of spreading, warranting oncological management.
- The patient has other medical conditions: If a patient has underlying health issues that complicate treatment decisions, an oncologist can provide specialized expertise.
The Oncological Treatment Process
If an oncologist becomes involved in your care, the treatment process will typically involve:
- Staging: Determining the extent of the cancer using imaging tests like CT scans, PET scans, or MRI.
- Treatment Planning: Developing a personalized treatment plan based on the type, stage, and characteristics of the cancer, as well as the patient’s overall health.
- Systemic Therapy: Administering treatments like chemotherapy, immunotherapy, or targeted therapy, which are designed to kill cancer cells throughout the body.
- Radiation Therapy: Using high-energy beams to kill cancer cells, often used in conjunction with other treatments.
- Follow-up Care: Regular monitoring to detect any signs of recurrence and manage any side effects from treatment.
Multidisciplinary Care Teams
In many cases, skin cancer treatment involves a multidisciplinary team approach, which may include:
- Dermatologist: Diagnoses and treats early-stage skin cancers.
- Surgical Oncologist: Performs surgeries to remove cancerous tumors and lymph nodes.
- Medical Oncologist: Administers systemic therapies like chemotherapy and immunotherapy.
- Radiation Oncologist: Delivers radiation therapy.
- Pathologist: Analyzes tissue samples to diagnose and classify the cancer.
This collaborative approach ensures that patients receive the most comprehensive and effective care.
Common Misconceptions
One common misconception is that all skin cancer requires treatment by an oncologist. This is not the case. The vast majority of BCCs and many SCCs can be successfully treated by dermatologists or surgeons. It is only in cases of more advanced or complex skin cancers that oncologists become essential.
Another misconception is that immunotherapy and targeted therapy are only for late-stage melanoma. While these therapies have revolutionized melanoma treatment, they are also being explored for other types of skin cancer, particularly advanced SCC.
Prevention and Early Detection
The best way to avoid needing to see an oncologist for skin cancer is through prevention and early detection:
- Wear sunscreen daily: Use a broad-spectrum sunscreen with an SPF of 30 or higher.
- Seek shade: Limit sun exposure, especially during peak hours (10 am to 4 pm).
- Wear protective clothing: Cover up with long sleeves, pants, and a wide-brimmed hat.
- Avoid tanning beds: Tanning beds emit harmful UV radiation that increases the risk of skin cancer.
- Perform regular self-exams: Check your skin regularly for any new or changing moles or lesions.
- See a dermatologist for annual skin exams: Especially if you have a family history of skin cancer or a large number of moles.

Frequently Asked Questions (FAQs)
Can a dermatologist treat all types of skin cancer?
No, a dermatologist cannot treat all types of skin cancer. While dermatologists are skilled in managing many early-stage basal cell and squamous cell carcinomas, more advanced or aggressive cases, particularly melanoma, often require the expertise of an oncologist.
What is the difference between a surgical oncologist and a medical oncologist in skin cancer treatment?
A surgical oncologist specializes in removing cancerous tumors surgically, while a medical oncologist focuses on treating cancer with systemic therapies like chemotherapy, immunotherapy, and targeted therapy, which circulate throughout the body.
What are the signs that my skin cancer may require treatment by an oncologist?
Signs that your skin cancer may need oncological treatment include: spread to lymph nodes or other organs, melanoma diagnosis (particularly at a later stage), recurrence after initial treatment, or if the cancer is deemed aggressive or high-risk based on pathology.
What types of tests might an oncologist order to determine the stage of my skin cancer?
An oncologist may order imaging tests like CT scans, PET scans, or MRIs to determine the extent (stage) of the skin cancer. They might also perform a sentinel lymph node biopsy to check for cancer spread to nearby lymph nodes.
What is immunotherapy, and how is it used to treat skin cancer?
Immunotherapy is a type of cancer treatment that helps your immune system fight cancer. In skin cancer, it can be used to treat advanced melanoma and some types of squamous cell carcinoma by boosting the body’s natural defenses to attack cancer cells.
What are targeted therapies, and how are they different from chemotherapy?
Targeted therapies are drugs that specifically target certain molecules or pathways involved in cancer cell growth and survival. Unlike chemotherapy, which kills all rapidly dividing cells, targeted therapies are designed to selectively attack cancer cells, potentially reducing side effects.
What are the potential side effects of chemotherapy and immunotherapy for skin cancer?
Chemotherapy side effects can include nausea, fatigue, hair loss, and increased risk of infection. Immunotherapy side effects can vary but may include skin rashes, fatigue, diarrhea, and inflammation of various organs. The severity of side effects varies from person to person.
How often should I see an oncologist for follow-up after skin cancer treatment?
The frequency of follow-up appointments with an oncologist after skin cancer treatment depends on the type and stage of the cancer, as well as the treatment received. Your oncologist will determine a personalized follow-up schedule based on your individual needs.
If I have a family history of skin cancer, should I automatically see an oncologist?
Having a family history of skin cancer does not automatically necessitate seeing an oncologist. However, it does increase your risk, and you should discuss this with your dermatologist, who can determine if more frequent skin exams or other preventive measures are needed. If a suspicious lesion is found, they will refer you as needed.
Can an oncologist perform surgery to remove skin cancer?
Some oncologists, specifically surgical oncologists, do perform surgery to remove skin cancer, especially in cases of advanced melanoma or when lymph node removal is required. However, many surgeries for early-stage skin cancers are performed by dermatologists or general surgeons.
Are there any alternative or complementary therapies that can help in skin cancer treatment, alongside standard medical care?
While some alternative and complementary therapies, like acupuncture or massage, may help manage side effects of skin cancer treatment, they are not a substitute for standard medical care. Always discuss any alternative therapies with your oncologist to ensure they are safe and do not interfere with your treatment plan.
What questions should I ask an oncologist if I am referred to one for skin cancer?
When meeting with an oncologist, you should ask questions about: the type and stage of your cancer, the treatment options available, the potential side effects of treatment, the expected outcomes of treatment, and the follow-up care plan. Don’t hesitate to bring a list of questions to your appointment.
