A tumor is an abnormal lump or growth of cells. When the cells in the tumor are normal, it is benign. Something just went wrong, and they overgrew and produced a lump. When the cells are abnormal and can grow uncontrollably, they are cancerous cells, and the tumor is malignant. Malignant means that the tumor is made of cancer cells and it can invade nearby tissues. Some cancer cells can move into the bloodstream or lymph nodes, where they can spread to other tissues within the body—this is called metastasis. Cancer can occur anywhere in the body including the breast, intestines, lungs, reproductive organs, blood, and skin. Some types of benign tumors only very rarely transform into malignant tumors. But some types, such as adenomatous polyps (adenomas) in the colon have a greater risk of transforming into cancer. That is why polyps, which are benign, are removed during colonoscopy. Removing them is one way of preventing colon cancer. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly.
