Skin carcinoma is the most common form of cancer. 80% of
them develop on the skin of face and neck and therefore can be detected early!
One in five Caucasians will develop skin cancer in the course of a lifetime,
while 1% of population in western countries develops skin cancer yearly. Risk
factors for skin cancer are spending a lot of time in the sun
or have been sunburned; having light-colored skin, hair and eyes; having a
family member with skin cancer; or age over 50. The two most common types are
basal cell carcinoma and squamous cell carcinoma.
Itch is the most commonly reported symptom in both types
of skin cancer. However, recent study performed at Wake Forest Baptist Medical
Center in Winston-Salem, USA, and published in the journal “Archives of
Dermatology” has found that pain is more common with squamous cell cancer.
Researchers looked at data from nearly 500 patients
treated for either basal cell carcinoma or squamous cell carcinoma. Itch was the most common symptom reported in both skin
cancers - 43 percent of patients with squamous cell and 33 percent of those
with basal cell reported the symptom. Pain was much more common in patients
with squamous cell carcinoma (almost 40 percent) than in those with basal cell
carcinoma (nearly 18 percent), the investigators found.
The results of this study suggest that a simple
assessment of pain intensity will aid in the clinical diagnosis of squamous
cell carcinoma and lead to appropriate treatment for these cancerous lesions
that are more aggressive than basal cell carcinoma. In the United States only,
about 4 million cases of basal cell and squamous cell cancers are diagnosed
each year.
