Skin cancer is one of the most common types of cancer worldwide, with more than 1.5 million new cases estimated in 2022⁽¹⁾. It is by far the most common of all types of cancer in the United States, with about 5.4 million basal and squamous cell skin cancers diagnosed each year. ⁽²⁾ 

Among the various treatment options available, brachytherapy stands out for its high cure rates and excellent cosmetic outcomes. This blog explores how brachytherapy offers a promising solution for treating basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), two prevalent forms of skin cancer. 

The types of Skin Cancer 

Skin cancer is one of the most common types of cancer worldwide, caused by the uncontrolled growth of abnormal skin cells. The three main types are: 

• Basal Cell Carcinoma (BCC): This is the most prevalent, accounting for about 80% of all skin cancer cases. BCC often appears as a pearly bump or a flat lesion in areas frequently exposed to the sun, like the face or neck. 

• Squamous Cell Carcinoma (SCC): Representing around 16% of skin cancer cases, SCC can appear as a firm, red nodule or a flat lesion with a scaly, crusted surface. It’s most commonly found on sun-exposed skin. 

• Melanoma: Though less common, making up about 4% of cases, melanoma is the most dangerous form due to its potential to spread rapidly. It often presents a large brown spot with darker speckles or a mole that changes in color, size, or texture. 

Early detection is crucial for effective treatment.  

What is Brachytherapy for Skin Cancer? 

Brachytherapy is an excellent noninvasive radiation therapy solution to complement or replace surgery for skin cancer. In this form of radiation therapy, the radioactive sources are delivered through an applicator or a needle, depending on the area to be treated. This allows a high radiation dose to be delivered to the cancer cells while minimizing exposure to surrounding healthy tissues.  

How Brachytherapy Works? 

1. Placement of Radioactive Material: The radioactive source is delivered through a superficial applicator placed on the skin or an interstitial applicator inserted into the tumor. 

2. Localized Treatment: The radioactive material delivers a high dose of radiation to the cancer cells while minimizing exposure to surrounding healthy tissue. 

3. Treatment Sessions: The treatment is usually delivered in a few short sessions, making it a convenient option for many patients. 

The procedure is typically performed on an outpatient basis. It involves a series of sessions, each lasting a few minutes. The precise placement of the radioactive sources ensures that the maximum radiation dose is concentrated on the tumor, enhancing the treatment’s effectiveness. 

High Cure Rates with Brachytherapy 

Brachytherapy has demonstrated impressive cure rates for skin cancer. Studies report cure rates of 85% to 90% for basal cell carcinoma and around 85% for squamous cell carcinoma. (3,4) 

These statistics highlight the effectiveness of brachytherapy in treating these types of skin cancers. It offers high cure rates and often excellent cosmetic outcomes, especially in elderly patients. These high success rates make brachytherapy a preferred option for many patients and healthcare providers.  

Advantages of Brachytherapy for Skin Cancer 

One of the primary advantages of brachytherapy is its precision. By delivering radiation directly to the tumor site, brachytherapy minimizes damage to surrounding healthy tissues. This targeted approach reduces the risk of side effects and preserves the appearance and function of the treated area. 

Cosmetic outcomes are another significant benefit. Brachytherapy often results in minimal scarring and excellent cosmetic results, which is particularly important for skin cancer patients concerned about the appearance of their skin post-treatment. 

Additionally, brachytherapy is convenient. Compared to other radiation therapies, it typically involves fewer sessions, reducing the overall treatment time and allowing patients to return to normal activities more quickly. 

Patient Stories 

Real-life examples highlight the effectiveness of brachytherapy. Take Carlos’ story, for instance. He shares his experience of being diagnosed with skin cancer and the decision to undergo brachytherapy. Carlos describes the treatment process as simpler than he thought it would be, as well as its effectiveness and the minimal side effects he experienced. His story is a testament to the benefits of brachytherapy, showcasing how it helped him overcome cancer while maintaining a good quality of life. 

Brachytherapy offers a high cure rate solution for skin cancer, particularly for basal cell carcinoma and squamous cell carcinoma. Its precision, reduced side effects, excellent cosmetic results, and convenience make it a preferred treatment option. If you or a loved one is facing a skin cancer diagnosis, consult with your healthcare provider about brachytherapy and explore all available treatment options.
