More Things You Think Cause Cancer but Do Not

Power lines emit both electric and magnetic energy, but do not cause cancer. According to the National Cancer Institute's fact sheet on Electromagnetic Fields and Cancer. 'The electric energy emitted by power lines is easily shielded or weakened by walls and other objects. The magnetic energy emitted by power lines is a low-frequency form of radiation that does not damage genes.

Slicing a tumor does not cause it to spread. During 2005, nearly 41 percent of people surveyed by the American Cancer Society said they believed that surgery to remove cancer actually caused cancer to spread, and an additional 13 percent were not sure. Surgeons use special protocols to prevent cancer cells from migrating during surgical procedures. Also, cancer replicates and metastasizes on its own, not with the help of a scalpel.

Exposure to air does not cause cancer to spread. "There is no scientific data supporting that theory," says Blair Marshall, MD, thoracic surgeon, on oncolink.com. Dr. Marshall writes that the theory stems from situations where cancer patients have surgery and then later die of metastatic cancer. "In actuality," Dr. Marshall reports, "if the patient had not undergone any surgery at all, they still would have developed widespread disease." This belief is more prevalent and difficult to disentangle in under-served groups, according to the study, and may contribute to disparities in cancer outcomes in those groups.
