Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [2] [7] These contrast with benign tumors, which do not spread. [7] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. [1]
Causes of cancer. Cancer requires multiple mutations to progress. Cancer is caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1][2] A minority of cancers are due to inherited genetic mutations. [3]
The history of cancer describes the development of the field of oncology and its role in the history of medicine.
Find out the basics about cancer, including symptoms, causes and treatments. Learn steps you can take to prevent cancer.
Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.
cancer, group of more than 100 distinct diseases characterized by the uncontrolled growth of abnormal cells in the body. Though cancer has been known since antiquity, some of the most significant advances in scientists’ understanding of it have been made since the middle of the 20th century.
Breast cancer is a cancer that develops from breast tissue. [7] Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. [1] In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or ...
There are two main categories of cancer: Hematologic (blood) cancers are cancers of the blood cells, including leukemia, lymphoma, and multiple myeloma. Solid tumor cancers are cancers of any of the other body organs or tissues. The most common solid tumors are breast, prostate, lung, and colorectal cancers.

Understanding Cancer. Cancer is not one disease, but a collection of related diseases that can occur almost anywhere in the body. At its most basic, cancer is a disease of the genes in the cells of our body. Genes control the way our cells work.
