Treatment for Non-Melanoma Skin Cancers
Non-melanoma skin cancers (NMSC) are becoming increasingly common due to the ageing population. They represent a group of clinically non-invasive and slow-growing tumours accounting for >75% of all skin cancers. The majority of NMSC consists of Basal Cell Carcinomas (BCC) and Squamous cell carcinomas (SCC), primarily resulting from sun exposure. As such they are often found on exposed sites, such as the face, ears, neck and hands.
Treatment for NMSC is through local excision or treatment by non-invasive therapies such as radiation or cryotherapy. In the treatment of T1 and T2 tumours, brachytherapy using radioactive sources has been shown to produce good local control and excellent cosmetic results.
Recently, electronic brachytherapy using x-rays has been used in the treatment of NMSC. Improvements have been shown over the use of radionucleotide brachytherapy due to reduced exposure of adjacent tissues to radiation, which may lead to fewer undesirable side effects. In addition, electronic x-ray brachytherapy can provide much quicker treatment times than traditional brachytherapy using radioactive sources.
