Cancer is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant properties of cancers differentiate them from benign tumors, which are self-limited, and do not invade or metastasize. Most cancers form a tumor but some, like leukemia, do not. This list looks at 10 common misconceptions about cancer.

1All Cancers Are The Same

Probably the biggest cancer misconception because the “Cure for Cancer” slogan makes people assume it is essentially one drug that will fix one illness. There are over a hundred types of cancer and they are all approached differently, depending on how much knowledge is known about the specific cancer and also depending on the patient’s specific needs. Thanks to the fund raising efforts of organizations such as Susan G. Komen and Avon, Medicine has made great advances in breast cancer research. Others, like pancreatic and esophageal cancers, are relatively out of the spotlight and as such, much is still being discovered and survival rates are still comparatively low.
