Ionizing radiation can cause cancer directly by damaging the DNA of a cell creating mutations thus increasing the probability of cancer. Heat is just heat. In extreme cases, it can cause severe burns. Cancers caused by burns and wounds are rare but possible. I think you may have factored in UV radiation that we receive from the sun, but this is something else: higher energy UV rays are ionizing radiation.
