Imiquimod may be used prior to surgery in order to reduce the size of the carcinoma. Some advocate the use of imiquimod prior to Mohs surgery to remove the superficial component of the cancer.Research suggests that treatment using Euphorbia peplus, a common garden weed, may be effective. Australian biopharmaceutical company Peplin is developing this as topical treatment for BCC. Radiation
Radiation therapy can be delivered either as external beam radiotherapy or as brachytherapy (mostly internal radiotherapy). Although radiotherapy is generally used in older patients who are not candidates for surgery, it is also used in cases where surgical excision will be disfiguring or difficult to reconstruct (especially on the tip of the nose, and the nostril rims). Radiation treatment with external radiation often takes as few as 5 visits to as many as 25 visits. Usually, the more visits scheduled for therapy, the less complication or damage is done to the normal tissue supporting the tumor. Radiotherapy can also be useful if surgical excision has been done incompletely or if the pathology report following surgery suggests a high risk of recurrence, for example if nerve involvement has been demonstrated. Cure rate can be as high as 95% for small tumor, or as low as 80% for large tumors. A variation of an external brachytherapy is the epidermal radioisotope therapy (e.g. with 188Re in form of the Rhenium-SCT). It is used in accordance to the general indications for brachytherapy and especially complex localisations or structures (e.g.
Halogen acne is caused by iodides, bromides and fluorides (halogens) that induce an acneiform eruption similar to that observed with steroids. See also
