Attraction is commonplace: we are attracted to a significant other, certain metals are attracted to magnets, and moths are attracted to flames. In some instances, attraction is not preferred, especially in the case of cancer. Primary tumors initially form in a host organ, and cancerous cells are eventually attracted to other organs in the body, forming secondary tumors known as metastases. This characteristic of cancer is the most devastating, and is largely the reason why cancer is incurable.
