What types of skin
cancer are there?
There
are three main types: Basal Cell Carcinoma (80%), Squamous Cell
Carcinoma (15%) and Malignant Melanoma (5%)
Basal
Cell Carcinoma - 80% of Skin
Cancer
Basal
Cell Carcinoma (BCC) is the most frequent type of skin cancer and
frequently develops on the central face, chest/back and lower leg.
It is a slow-growing type of skin cancer and does not nromally spread
to other body tissues or lymph glands. It usually presents as a
small raised pearly nodule or a red palque on the skin that may
bleed or ulcerate. Whilst slow-growing, it can cause significant
tissue destruction if left untreated. We always recommend treatment
except in very elderly patients with small superfiical tumours.
Treatment depends on the site of the skin cancer and how deep it
is in the skin. Superficial BCC's may be treated by topical creams,
scraping (curettage), photodynamic therapy (PDT), or skin surgery.
Deeper invasive BCC requires skin surgery or radiotherapy X-Ray
treatment.




Squamous
Cell Carcinoma - 15% of Skin Cancer
This is more frequently
seen in sites of high intensity sun exposure including the scalp,
face, ears and back of the hands. It usually presents as a radily
growing skin nodule that may bleed and ulcerate. Treatment is essential
as the skin cancer can spread to lymph glands. Skin surgery or radiotherapy
are normally recommended to remove the abnormal skin.
Malignant
Melanoma- 5% of Skin Cancer
This is the most dangerous type of skin cancer and is
due to the abnormal growth of cells called melanocytes. Melanocytes
produce brown pigment in the skin and are responsible for moles.
When these cells grow abnormally they produce change in a pre-existing
mole or development of a new mole that has irregular features. It
is important to have any moles checked if they increase in size
(more than 6mm in diameter), lose symmetry, change in colour (develop
dark black pigment), or produce symptoms (redness, bleeding or itching).
We have a mole
scanner at the clinic and all of our consultant team are experts
in diagnosing skin cancer.
