Understanding Basal Cell Carcinoma of Skin of Left Ear and External Auricular Canal

Basal cell carcinoma is a type of skin cancer that affects the basal cells, which are responsible for producing new skin cells. It is the most common type of skin cancer, and it usually occurs on areas of the skin that are exposed to the sun, such as the face, neck, and ears. Basal cell carcinoma of the skin of the left ear and external auricular canal is a specific type of basal cell carcinoma that affects these areas.

The external auricular canal is the part of the ear that leads to the eardrum, and it is lined with skin. Basal cell carcinoma of the external auricular canal can cause symptoms such as hearing loss, ear pain, and discharge from the ear. It is important to note that this type of cancer is typically slow-growing and rarely spreads to other parts of the body, but it can cause significant damage if it is not treated.

1. Causes

The main cause of basal cell carcinoma is exposure to ultraviolet (UV) radiation from the sun or tanning beds. Other risk factors include having fair skin, a history of sunburns, and a weakened immune system.

2. Symptoms

Symptoms of basal cell carcinoma of the skin of the left ear and external auricular canal may include a small, shiny, or pearly bump on the skin, a flat, scaly, or brown patch on the skin, or a red or irritated area on the skin. Other symptoms may include bleeding from the bump or sore, oozing or crusting of the bump or sore, or an indentation in the center of the bump.

3. Diagnosis

To diagnose basal cell carcinoma of the skin of the left ear and external auricular canal, a doctor will perform a physical examination of the affected area and may take a biopsy of the lesion. The biopsy involves removing a small sample of tissue from the lesion and examining it under a microscope to determine whether cancer cells are present.

4. Prevention

The best way to prevent basal cell carcinoma is to protect your skin from the sun. This can be done by wearing protective clothing, such as hats and long-sleeved shirts, staying in the shade, and using sunscreen with an SPF of 30 or higher. It is also important to avoid tanning beds and to avoid being outside during peak sun hours, which are typically between 10 am and 2 pm.

In conclusion, basal cell carcinoma of the skin of the left ear and external auricular canal is a type of skin cancer that requires proper attention and care. It is important to protect your skin from the sun and to seek
