What is Cancer?

According to the Centers for Disease Control and Prevention (CDC), approximately 12.7 million people around the world learn that they have cancer each year.

Cancer is defined as a class of diseases where malignant or abnormal cells divide uncontrollably and form lumps or masses known as tumors. Tumors can grow and impact circulatory, digestive and nervous systems, and can release hormones that can affect body functions. In cancerous tumors, cells can break off the tumors, or metastasize, to invade and grow in different parts of the body. Tumors that remain in an isolated area of the body and show signs of limited growth are typically known as benign, or slightly abnormal. In cases of leukemia, cancer prevents normal blood function through abnormal cell division in the blood stream. Oncology is the medical practice of diagnosing and treating cancer.
