New skin patch treatment kills most common form of skin cancer | Machines Like Us
One in three cancers diagnosed around the world are skin cancers. In the USA, 1 in 5 Americans will get skin cancer at some point in their lives.
There are two types of skin cancers:
1) melanomas, which form deep in the cells that generate skin pigment, and
2) non-melanoma cancers, like basal cell carcinoma and squamous cell carcinoma
This patch treats basal cell carcinoma, specifically. It killed the cancer in 80% of all patients, although the sampling was pretty small (10 patients, all of whom were tested at 3 years after treatment).
In this study, a total of 10 patients between the ages of 32 and 74 years with facial basal cell carcinoma were treated with custom-made and fully sealed P-32 patches. Subjects had lesions near the eyes, the nose and the forehead, and all were treated locally with the P-32 patch for three hours on an outpatient basis. The custom patches were reapplied on the fourth and seventh days after the first treatment for another three hours each, delivering a fragmented dose of 100 Gy (a measurement of radiation exposure) to the cancerous lesions only—without harming deeper structures or other areas of healthy skin on the face. Biopsies were taken at three months and repeated within the three years that followed treatment, and eight out of 10 patients were found to be entirely cured and cancer free.
