We provide professional support in Skin Cancer.
Skin cancer is the overgrowth of skin cells that are more
commonly exposed to sunlight. However, this common type of cancer can begin in
skin areas that are not exposed to sun in normal circumstances.
There are three main types of skin cancer: basal cell
carcinoma, squamous cell carcinoma and melanoma
Limiting or avoiding exposure to ultraviolet (UV) beams
can decrease your risk of skin cancer. Evaluation of your skin for suspicious
changes can help early diagnosis of cancer. Early diagnosis of cancer gives the
highest chance of success treatment.
Basal cell carcinoma generally develops in body parts
that are exposed to sun, such as face or neck.
Basal cell carcinoma may be manifested as follows:
Waxy lump appearing like a pearl.
Flat, flesh or brown colored lesion that appears like a
Squamous cell carcinoma generally develops in sun exposed
areas such as face, ears or hands. Squamous cell cancer is more likely to
develop in skin areas that are not ordinarily exposed to sun in people with
Squamous cell carcinoma can be manifested by;
A firm, red nodule
A flat lesion with scaly or crusted surface
Melanoma can occur at any part of the body with no specific
sign or symptom or it may occur in an existing mole that transforms into
cancer. Melanoma is typically seen on the face or trunk of men. This type of
cancer is more commonly observed in the lower legs of female patients. Melanoma
may develop on skin that is not exposed to sun in both genders.
Melanoma can occur in all people regardless of the skin tone. However, it tends to occur in palms or
soles or the skin underneath the fingernails and toenails in people with dark
Signs of meloma include: Large brownish spot with darker speckles.
A mole that changes in size, color or feeling or that bleeds
A small red, white, blue or blue-black colored lesion with irregular borders.
Dark colored lesions in palms, soles, finger tips or toes
or mucous membranes lining your mouth, nose, vagina or anus.
Types of cells in skin cancer: Skin cancer originates from the epidermis, the uppermost layer of the skin. Epidermis is a thin layer that
provides the protective sheath consisting of skin cells, which are continuously
shed. Epidermis hosts 3 major types of cells:
Identifying the origin of the cancer allows determining the type of cancer and treatment options.
Ultraviolet light and other potential causes
The damage in DNA of skin cells is mostly caused by ultraviolet radiation found in sun rays and lights
used in solariums. However, the sun exposure cannot explain the fact that skin
cancers may also occur in skin that is not exposed to sun in normal
circumstances. This finding points to potential of other risk factors that may
contribute to your risk of cancer, such as exposure to toxic substances or
diseases that weaken the immune system.
