Carcinoma in situ of skin of ear and external auricular canal
Carcinoma in situ of the skin of the ear and external auricular canal is a type of skin cancer that develops in the outer ear. Unlike other types of skin cancer, it is relatively rare, accounting for less than 1% of all skin cancers. However, it can be aggressive and spread to other parts of the body if left untreated.
Like other types of skin cancer, carcinoma in situ of the skin of the ear and external auricular canal is caused by exposure to the sun's harmful UV rays. People who spend a lot of time in the sun or who have a history of sunburn are at an increased risk of developing this type of cancer. Other risk factors include a weakened immune system, exposure to certain chemicals and radiation therapy.
Some of the symptoms of carcinoma in situ of the skin of the ear and external auricular canal include a lump or sore that doesn't heal, bleeding or discharge from the ear, and pain or discomfort in the ear. If you experience any of these symptoms, it's important to see a doctor as soon as possible.
Treatment
The treatment for carcinoma in situ of the skin of the ear and external auricular canal depends on the size and location of the cancer, as well as the overall health of the patient. In some cases, surgery may be required to remove the cancerous tissue. This may involve removing the entire ear or just a portion of it. Other treatments may include radiation therapy or chemotherapy.
If you have been diagnosed with carcinoma in situ of the skin of the ear and external auricular canal, it's important to work closely with your doctor to develop a treatment plan that is right for you. This may involve a combination of different treatments, depending on the severity of the cancer and your overall health.
