Comprehensive physician-reviewed information about basal cell carcinoma, In addition, BCC sometimes resembles noncancerous skin conditions such as. Basal-cell carcinoma (BCC), also known as basal-cell cancer, is the most common type of skin cancer. It often appears as a painless raised area of skin, which.
Carcinoma Basal (BCC) Cell
Eventually they may appear as a non-healing sore. BCCs are often not noticed until relatively well developed and their appearance can be confused with that of a naevus mole , patch of dermatitis , or a scar.
A lesion that bleeds on the face is quite suspicious of BCC. Superficial BCCs are confined to the very top layers of the skin so are often more easily treated with topical and non-surgical techniques. They can however become relatively broad in size. Superficial BCCs are especially common on the trunk. This type of BCC usually appears as a rounded lump on the skin. They are less likely to have invisible extension under the surface of the skin than other types of BCC.
These are the most troublesome type of BCC as they are usually larger than they appear to the naked eye. They are usually the most difficult to see and are often not detected until well advanced.
It is therefore not uncommon for this type to be inadvertently incompletely removed with treatment, allowing the BCC to continue to grow and recur. Morphoeic and micronodular are different types of infiltrating BCCs. Usually a biopsy a small sample of the lesion is taken and sent to the pathology laboratory to be examined under the microscope to confirm the diagnosis. The freeze time is prolonged and multiple freeze thaw-cycles may be used, as determined by the treating doctor.
This method is mainly used to treat superficial BCCs. If the diagnosis is not certain, a biopsy should precede the procedure. This form of treatment is quick, inexpensive, and has a high cure rate if freezing is prolonged. It is less often used in cosmetically sensitive or highly visible areas as it has a relatively high risk of scarring. This involves cutting out the lesion with a safety margin and suturing stitching the skin back together.
It is standard practice to remove the lesion with a 4mm or more safety margin to minimise the chance of leaving any tumour cells behind. This technique gives the highest cure rate. It was developed especially for BCCs found on the face where it is important to remove them with a very high cure rate as well as minimise the amount of skin removed in order to achieve the best possible cosmetic outcome.
It involves surgical excision removal of the lesion with a narrow margin, testing of the pathology while the person waits, ensuring no BCC is left behind, before suturing stitching the wound. Curettage and cautery involves injection of local anaesthetic, followed by scraping the lesion from the skin surface with a curette and then cauterisation heat-sealing with a hot wire of the base.
It typically heals with a pale scar a little wider than the lesion that was treated. It is often used for superficial BCCs on the trunk and limbs. They are more common the closer you live to the equator.
Unlike other skin cancers such as melanoma, it is very unusual for a BCC to spread from where it starts to other parts of the body, although they can expand and penetrate deeply into the skin if they are not detected and treated.
There are several subtypes, with Superficial and Nodular being the least likely to penetrate deeply, whereas Miconodular and Morphoeic types tend to bury deeply and widely into the skin. View the embedded image gallery online at: Some people are particularly prone to this type of skin cancer, which are most commonly diagnosed in people with fair skin, although they can occur less commonly in people with olive and darker complexions. Outdoor workers and sportspeople are prone to BCC, which is why it is necessary to always remember to wear sun protective clothing and protect the skin from the sun when outdoors.
Typically BCC is a slow growing type of skin cancer, often on the face and upper body, and may be noticed as a flat or slightly raised pink or multicoloured spot, which may weep slightly when wiped with a towel.
Sometimes they feel irritated. The micronodular and morphoeic types tend to look more like a thick, flat white scar. If you notice a spot appear that looks like a pimple that will not heal over a few weeks then it may be a BCC and you should consult your doctor. A small skin biopsy may be required to confirm the diagnosis. If a BCC is detected then a suitable management plan can be tailored according to the location and subtype of the BCC.
