Skin cancer is the most prevalent disease. While many forms of skin cancer can be treated effectively with surgery, radiation therapy is a critical treatment option, particularly for those with specific circumstances or advanced cases. This non-invasive method uses targeted radiation to destroy cancerous cells, offering an alternative to surgical procedures. Factors such as the type, stage, and location of the skin cancer, as well as personal health conditions, play a significant role in determining its suitability.

This blog will explore radiation therapy for skin cancer as a treatment for skin cancer, providing insights into how it works, who it’s best suited for, and what to expect during the process. Let's start.

Skin Cancer: Overview

Skin cancer primarily develops in areas exposed to the sun, such as the face, neck, and hands, but it can occur anywhere on the body. There are three main types of skin cancer:

Basal Cell Carcinoma (BCC): The most common type, BCC rarely spreads to other parts of the body but can cause significant damage to surrounding tissue if left untreated.
Squamous Cell Carcinoma (SCC): This type is more aggressive than BCC and can spread to other organs if not treated promptly.
Melanoma: The most dangerous form of skin cancer, melanoma is less common but more likely to metastasise and can be life-threatening.

What Is Radiation Therapy?

Radiation therapy involves using high-energy rays or particles to destroy cancer cells. The therapy targets the DNA within cancer cells, causing damage that inhibits their ability to grow and divide. Over time, the cancer cells die, and the tumour shrinks.

When Is Radiation Therapy Used for Skin Cancer?

While surgery is the most common treatment for skin cancer, radiation therapy is a valuable alternative or supplementary option in certain cases, including:

Inoperable tumours: Radiation therapy is often used when surgery is not feasible due to the tumour's location (e.g., on the eyelids or nose) or if the patient has other health conditions that make surgery risky.
Older patients: Elderly individuals or those in poor health may opt for radiation therapy if they are not good candidates for surgery.
Recurrent skin cancer: For patients whose skin cancer returns after surgery, radiation therapy can be used to target remaining or recurring cancer cells.
Lymph node involvement: In cases where skin cancer has spread to nearby lymph nodes, radiation therapy can help control the spread of the disease.

Types of Radiation Therapy for Skin Cancer

Several types of skin cancer radiation techniques may be used to treat skin cancer, depending on the type, size, and location of the cancer:

External Beam Radiation Therapy (EBRT): EBRT uses a machine that directs high-energy beams at the cancer site from outside the body. It is a non-invasive treatment that usually requires several sessions over a few weeks.
Superficial Radiation Therapy (SRT): This technique uses lower-energy radiation that penetrates just a few millimetres into the skin, making it ideal for treating non-melanoma skin cancers like BCC and SCC.
Brachytherapy: In this less common approach, radioactive material is placed directly on or near the cancerous area. Brachytherapy is typically used for more localised or superficial cancers.

Did You Know?

Skin cancer is the most common form of cancer worldwide, with over 5 million cases diagnosed each year, yet it's also one of the most preventable types with proper sun protection.
Even when it's cloudy, around 80% of the sun's ultraviolet (UV) rays can still reach your skin, contributing to an increased risk of skin cancer over time.

Myths and Facts About Radiation Therapy for Skin Cancer

Let’s explore some common myths and facts about skin cancer and radiation therapy.

Myth 1: Radiation therapy is painful and invasive.
Fact: Radiation therapy is non-invasive and generally painless. The procedure targets cancerous cells with precision, minimizing discomfort during treatment.

Myth 2 : Skin cancer only occurs in areas exposed to the sun.
Fact: Skin cancer can develop anywhere on your body, including places like the scalp, under the nails, or even the soles of your feet. Regular skin checks are crucial for early detection.

Myth 3 : Using sunscreen once a day is enough to protect you from skin cancer.
Fact: Sunscreen should be reapplied every two hours, especially after swimming or sweating, to ensure effective protection against harmful UV rays.

Conclusion

Radiation therapy plays a crucial role in the management of skin cancer, particularly for patients who are not candidates for surgery or those dealing with recurrent disease. While it is generally a safe and effective treatment, patients need to have an in-depth discussion with their healthcare team to understand the potential benefits and risks.

FAQs About Radiation Therapy for Skin Cancer

Q. How do you detect skin cancer early?
A. Early detection of skin cancer involves regular self-examinations, looking for new or changing moles, and unusual skin growths, and scheduling annual skin checks with a dermatologist for professional evaluation.

Q. Can I live a full life with skin cancer?
A. It's possible to live a full life with skin cancer, especially with early detection and treatment. Regular check-ups, sun protection, and healthy lifestyle choices can help manage the condition and improve overall quality of life.

Q. How does radiation therapy work for skin cancer?
A. Radiation therapy works by damaging the DNA of cancer cells, preventing them from growing and dividing. Over time, these damaged cells die, and the body naturally removes them.

Q. When is radiation therapy recommended for skin cancer?
A. Radiation therapy is recommended in the following cases:

When the cancer is located in a hard-to-treat area, like the face, ears, or eyelids.
For patients who cannot undergo surgery due to health reasons.
To treat recurrent skin cancer after previous surgery or treatments.
As an additional treatment post-surgery to reduce the risk of recurrence.

Q. Is radiation therapy safe for older adults?
A. Yes, radiation therapy is often a preferred treatment option for older adults who may not be candidates for surgery. It is generally well-tolerated, and the treatment plan can be adjusted to minimise risks.
