Cancer News Digest: The Latest Developments in Cancer Research and Treatment
Cancer is a broad term used to describe many different diseases. In general, cancer happens when abnormal cells in your body grow out of control and crowd out normal cells.
It can start almost anywhere. Cancer can stay in one spot, or it can metastasize — spread throughout your body. Some cancers grow slowly, while others grow quickly.
Most cancers are named for where they start in the body. For instance, “breast cancer” begins in your breast tissue.
Many cancers form solid tumors, which are growths of tissue. But blood cancers, such as leukemia, don’t generally grow as tumors; they stay in the form of individual cells. Tumors can be either malignant (cancerous) or benign (noncancerous).

Common Questions: Cancer
What is cancer?
Cancer is a disease of abnormal cell growth. Cells within the body lose the capacity
to stop dividing, and proliferate to the point that they invade normal tissue and impede the function of organ systems. It can occur in many different organs and
types of tissue.
What are some early signs of cancer?
Some common early signs of cancer include unexplained weight loss, fatigue,
unusual bleeding or discharge, a lump or thickening of the skin, fever, and/or drenching night sweats. However, it’s important to note that the signs/symptoms
are often not the same between cancer types (e.g. breast cancer versus colon
cancer), and even between patients with the same type of cancer.

How does cancer start?
Cancer starts when genes within an individual cell develop several errors, or mutations, that keep them from controlling the process of cell division. It usually
takes several mutations for a cell to become cancerous. Mutations may be inherited
or acquired through age or exposure to carcinogens in the environment, such as cigarette smoke
How do you die from cancer?
Cancer kills when it invades organs and prevents them from functioning, which happens in the later stages of the disease.
