Many of the 55 responders who died from cancer had cancer before September 11, 2001, but most of the cancer patients developed the disease afterward. The 98 deaths up to 2008 included: 55 cancers; 21 traumatic injuries (motor-vehicle crashes, gunshots and five homicides, including four cops killed in the line of duty)
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] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4]
Constitutional Symptoms. Unexplained pain: Pain that persists, has no clear cause, and does not respond to treatment may be a warning sign of many types of cancers. Unexplained night sweats or fever: These may be signs of an immune system cancer. Fever in children rarely points to malignancy, but may merit evaluation.

[7] Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. [1]
Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia.
An alarming new study showed that a medical condition that nearly one-third of Americans have—metabolic syndrome— is linked to a 30% increase in the risk of several different cancers. A ...
A precancerous condition is a condition, tumor or lesion involving abnormal cells which are associated with an increased risk of developing into cancer. [1] [2] [3] Clinically, precancerous conditions encompass a variety of abnormal tissues with an increased risk of developing into cancer. Some of the most common precancerous conditions include ...
