Basal Cell Carcinoma: Risks & Dangers of This Skin Cancer
The epidermis, the top layer of skin, develops a lump or lesion as a result of the most prevalent type of skin cancer, basal cell carcinoma. The majority of time, basal cell carcinoma develops on skin that has been exposed repeatedly to (UV) radiation from the sun, notably on the face and neck.
While basal cell carcinoma is uncommon to travel from your skin to other regions of your body, it can infect your bones or other cells under your skin. Basal cell carcinoma frequently resembles a small, occasionally shiny, or a scaly flat patch on your skin that slowly expands. If discovered early enough, basal cell carcinoma is curable. You will learn important information about this cancer, its causes, symptoms, and treatment in this post. So make sure to finish reading.
Causes of Basal Cell Carcinoma
Basal cell carcinoma is caused by a DNA mutation. Basal cells are located at the base of the epidermis. As new skin cells are created, basal cells push the older skin cells to the epidermis' surface where they might die or be shed off.
A basal cell's DNA regulates the process of producing new skin; a DNA mutation leads the basal cells to make aberrant cells, which would amass and form a malignant tumour. The sun's ultraviolet (UV) radiation or tanning beds are the main culprits for the modification or mutation to the DNA cells.
Risk Factors
Your chance of developing basal cell carcinoma may rise due to several conditions.
-
- Exposure to industrial substances including radiation, coal tar, or arsenic.
-
- Repeated sunburns
-
- Blonde, fair-skinned, or having red hair
-
- A history of basal cell carcinoma in the family
-
- Radiation treatment
-
- Previous skin cancer history
-
- Specific medical disorders or immunosuppressant drugs
-
- Prolonged sun exposure without protection
-
- Syndromes inherited that lead to skin cancer
Symptoms
-
- Growth with unusual blood vessels around it
-
- Flat spot or patch of skin
-
- Moles with uneven shapes or surrounding borders
-
- Sores that bleed and don't seem to heal well
-
- Area of scar-like tissue with no previous procedure
-
- Smooth, pearly, or waxy bumps
Treatment Options
Skin medications
If basal cell carcinoma is not too deep in the skin, creams containing drugs like imiquimod or 5 fluorouracil can be applied to the infected skin's surface. These creams have a variety of side effects, including inflammation, burning, itching, irritation, pain, and swelling, but if the treatment is successful, the cells will recover.
Surgery
There are different types of surgical options that may be used to remove cancerous cells, such as;
-
Curettage and electrodesiccation: the removal of the tumour’s surface tissue followed by electrical energy pulses
-
Excision: A surgical procedure in which the entire tumour and the surrounding border of healthy skin are removed.
-
Cryosurgery: In this procedure, a cold material, such as liquid nitrogen, is used to freeze the tumour.
-
Mohs surgery: This method removes the skin cancer one layer at a time while leaving the healthy tissue alone.
Radiation therapy
This surgical procedure is often used on patients who cannot undergo surgery for specific reasons best known to the doctor. If you notice any unusual sores on your skin that refuse to heal, have them examined immediately by a certified skin cancer clinic such as Skin Clinic Robina.
