Basal cell carcinoma versus squamous cell carcinoma

February 19, 2024

You may have heard about two types of non-melanoma skin cancer: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). While both are common forms of non-melanoma skin cancer, they differ in their risk factors, appearance and treatment options. So, let’s explore some of the differences between basal cell carcinoma versus squamous cell carcinoma.

Basal cell carcinoma

BCC is the most common type of non-melanoma skin cancer, accounting for about 80% of all non-melanoma skin cancer cases. It develops in the basal cells, which are located in the bottom layer of the epidermis. BCC is usually caused by prolonged exposure to the sun, especially in people with fair skin. Other risk factors include a weakened immune system, exposure to certain chemicals and a family history of the disease.

Squamous cell carcinoma

SCC, on the other hand, is less common than BCC, but it is still a serious form of non-melanoma skin cancer. It develops in the squamous cells, which are located in the upper layers of the epidermis. SCC is also caused by prolonged exposure to the sun, especially in people with fair skin. Other risk factors include a history of non-melanoma skin cancer, a weakened immune system and exposure to certain chemicals.

Physical characteristics: basal cell carcinoma versus squamous cell carcinoma

When it comes to appearance, both cancers can look similar, but there are some differences between basal cell carcinoma versus squamous cell carcinoma. BCC usually appears as a small, raised bump that may be pearly or waxy. It may also have a central depression and visible blood vessels. SCC, on the other hand, may look like a scaly patch, a raised bump or a sore that doesn’t heal. It may also have a crust or bleeding.

Treatments

Treatment options for basal cell carcinoma versus squamous cell carcinoma depend on the size, location and stage of the cancer. In general, both types of non-melanoma skin cancer can be treated with surgery, radiation therapy or topical medications. BCC is usually treated with surgery, while SCC may be treated with a combination of surgery and radiation therapy. Topical medications may also be used for both types of non-melanoma skin cancer, especially for small tumors or early-stage cancers.

If you have been diagnosed with BCC or SCC, it’s important to work closely with your health care team to develop the best treatment plan for you. This may involve a combination of different treatments, depending on the specifics of your cancer.

Prevention: basal cell carcinoma versus squamous cell carcinoma

In addition to treatment, there are also several things you can do to reduce your risk of developing non-melanoma skin cancer in the first place. These include:

– Avoiding prolonged exposure to the sun, especially during peak hours (between 10 am and 4 pm)

– Wearing protective clothing, such as long-sleeved shirts, hats and sunglasses

– Applying sunscreen with an SPF of at least 30, and reapplying every two hours or after swimming or sweating

– Avoiding tanning beds and other artificial sources of UV radiation

By taking these steps, you can help protect your skin and reduce your risk of developing non-melanoma skin cancer. If you have any concerns about your skin or notice any changes, be sure to talk to your health care provider right away. With early detection and treatment, most cases of non-melanoma skin cancer can be successfully treated.
