The report of differences between skin cancer rates and solid tumours in sunny versus less sunny countries [Tuohimaa P, Pukkala E, Scelo G, et al. Does solar exposure, as indicated by the non-melanoma skin cancers, protect from solid cancers: Vitamin D as a possible explanation. Eur J Cancer 2007; 43: 1701-12] raised some important questions regarding the roles of solar ultraviolet (UV) irradia...
this investigation was done in kennan from march 1989 to march 1993 to study the epidemiology of cancers in this province and to compare the results with a previous study performed in this area and some available statistics. a total number of 288 1 new cases of malignancy were registered and the crude relative frequency of cancers was studied. gastric cancer with a frequency of 9.7%, malignant ...

In Iran, cancerMethodsRegistry Center of Health Heputy for Sistan and Baluchestan province. Common cancers weredefi...
BACKGROUND Sjögren's syndrome is a chronic, systemic disorder of an autoimmune nature, and its primary etiopathogenetic events are not known. Previous studies have found elevated incidence of malignancies in patients with primary Sjögren's syndrome. However, there are few reports regarding the association of Sjögren's syndrome with skin cancers, especially with multiple skin cancers developed w...
Non-melanoma skin cancer (NMSC) is traditionally treated with surgical excision. Nonsurgical methods such as cryotherapy and topical chemotherapeutics, amongst other treatments, are other options. Actinic keratosis (AKs) are considered precancerous lesions that eventually may progress to squamous cell carcinoma (SCC). Photodynamic therapy (PDT) offers an effective treatment for AKs, and is also...
The p53 gene (TP53) is mutated in numerous human cancers. We have used it as a molecular target to characterize the induction of mutations in human skin cancers. About 50% of all skin cancers in normal individuals exhibit p53 mutations. This frequency rises to 90% in skin cancers of patients with the DNA-repair deficiency known as xeroderma pigmentosum (XP). These mutations are characterized by...
Nanotechnology involves the engineering of functional systems at nanoscale, thus being attractive for disciplines ranging from materials science to biomedicine. One of the most active research areas of the nanotechnology is nanomedicine, which applies nanotechnology to highly specific medical interventions for prevention, diagnosis, and treatment of diseases, including cancer disease. Over the ...
Mr LA has long been troubled with actinic damage to his skin, especially his face. He has had many squamous cell carcinomas (SCCs) removed and many solar keratoses managed. On this occasion Mr LA had two actinic lesions on his left cheek that failed to respond to cryotherapy. A biopsy of each site produced a surprise. Histology of the superior lesion revealed sebaceous carcinoma. This is an unc...
