1. Radiation exposure
Radiations have a wavelength capable of causing alterations in the cell, especially in the DNA. Not all rays have the same problem, but we can include X-rays and other medical imaging techniques as sources of radiation. However, they are still used because they are safe and only trigger cancer after daily exposure. That’s why radiology technicians need to take a break for months as a preventative measure to avoid cancer. Another source of exposure is radiotherapy. That’s why sometimes cancer therapy triggers cancer in a new location, especially in the form of leukemia.
