A medical term used to describe a severe and progressively worsening disease, mostly used as a description of cancer.
Benign Tumor Definition
A tumor that lacks the malignant properties of a cancer. A benign tumor does not grow in an unlimited, aggressive manner, does not invade surrounding tissues, and does not metastasize. Examples of benign tumors include moles and uterine fibroids.
Nearly all cancers are caused by abnormalities in the genetic material of the transformed cells. These abnormalities may be due to the effects of carcinogens, such as tobacco smoke, radiation, chemicals, or infectious agents. Other cancer-promoting genetic abnormalities may be randomly acquired through errors in DNA replication, or are inherited, and thus present in all cells from birth.
Cancer Symptoms and Treatment
Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. The choice of therapy depends upon the location and grade of the tumor and the stage of the disease, as well as the general state of the patient.
The use of ionizing radiation to kill cancer cells and shrink tumors. Radiation therapy can be administered externally via external beam radiotherapy (EBRT) or internally via brachytherapy.
In theory, non-hematological cancers can be cured if entirely removed by surgery, but this is not always possible. When the cancer has metastasized to other sites in the body prior to surgery, complete surgical excision is usually impossible.
The treatment of cancer with drugs ("anticancer drugs") that can destroy cancer cells. In current usage, the term "chemotherapy" usually refers to cytotoxic drugs which affect rapidly dividing cells in general, in contrast with targeted therapy.
Chemotherapy drugs interfere with cell division in various possible ways, e.g. with the duplication of DNA or the separation of newly formed chromosomes.
Cancer symptoms can be generally divided into three groups:
Symptoms of metastasis (spreading):
Although advanced cancer may cause pain, it is often not the first symptom.

The lavender colored ribbon brings awareness to all types of cancers - including cancers that do not have a specific awareness color, or the lavender colored ribbon may be used to represent a variety of different cancers that families might have experienced.
February is U.S. national cancer prevention month, and world cancer day is on February 4th.
