Squamous Cell Carcinoma of Skin of Ear and External Auricular Canal - Causes, Symptoms, and Treatment
Squamous cell carcinoma is a type of skin cancer that affects the squamous cells in the skin's outermost layer. It is a relatively common type of skin cancer that develops primarily due to long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds. However, squamous cell carcinoma can also develop in areas of the skin that are not exposed to the sun, such as the ear and external auricular canal. In this article, we will discuss the causes, symptoms, and treatment options for squamous cell carcinoma of the skin of the ear and external auricular canal.
Causes
The primary cause of squamous cell carcinoma is exposure to UV radiation. However, in the case of squamous cell carcinoma of the ear and external auricular canal, other factors can also contribute to the disease's development. These factors include:
- Exposure to industrial chemicals such as arsenic, tar, and soot
- Chronic infections such as human papillomavirus (HPV)
- Previous radiation therapy to the head and neck area
Symptoms
The symptoms of squamous cell carcinoma of the ear and external auricular canal can vary depending on the severity of the disease. Some common symptoms include:
- A sore or lump on the ear or in the ear canal that does not heal
- Persistent pain in the ear or ear canal
- Difficulty hearing or a feeling of fullness in the ear
- Bleeding from the ear or a discharge that is not earwax
If you experience any of these symptoms, it is important to see your doctor immediately.
Treatment
The treatment for squamous cell carcinoma of the ear and external auricular canal depends on the severity of the disease. In most cases, surgery is the preferred treatment option. This may involve removing the affected tissue and reconstructing any damage to the ear or ear canal. Radiation therapy and chemotherapy may also be used in some cases, particularly in more advanced stages of the disease.
It is essential to take steps to prevent squamous cell carcinoma of the skin of the ear and external auricular canal. This may involve protecting your skin from the sun's harmful rays by wearing protective clothing, using sunscreen, and avoiding tanning beds. Additionally, you should avoid exposure to industrial chemicals and other potential carcinogens whenever possible.
