Phosphorus-32 is the most common isotope used in the treatment of skin cancer.
Phosphorus-32 has been used to treat skin cancer since 1943.
In a recent development, it is applied as a skin patch containing the isotope.
It kills skin cancers after a few treatments, without harming healthy areas of skin.
This therapy is ideal for patients with skin cancers that are difficult to operate on, especially if skin grafting after surgery would be a challenge.
Even more exciting is a new type of therapy that has not yet been approved for use.
Researchers have developed a skin cream containing rhenium-288 that kills cancerous cells in less than an hour.
Let's hope that this new cream passes its clinical trials.
