Sometimes this process of new cell growth is not working properly and forms of cancer. Normal cells become cancer cells because of damage to DNA. Dna is in every cell and directs all its actions. In a normal cell, when DNA is damaged, the cell either repairs the damage or it dies. In cancer cells, the damaged DNA is not fixed, but the cell does not die like it should.
Instead, this unit continues to make new cells that the body does not need. The abnormal cells can turn into a mass or tumor. A malignant tumor or cancer can spread to other parts of the body form and other tumors. Some cancers, like leukemia, rarely form tumors. Instead, these cancer cells in blood and blood-forming organs, and circulate through other tissues where they grow. One of the two men and one in three women will be diagnosed with cancer at some point in their lives.
In New York state, nearly one in four deaths is from cancer. Cancer can occur at any age but is most commonly found in middle-aged and older. The number of cancer patients has increased over the past 40 years. Most of this is due to an increase in population and because people live longer.
The most common cancers found in males, in addition to skin cancer are prostate, lung and colon cancer. cancers of the breast, lung and colon are the most common cancers in women. Sometimes there is a family history of cancer. Scientists agree that people can get cancer with long-term repeated contact with carcinogens. Our personal habits and lifestyle can also contribute to cancers. They usually appear between five to 40 years after exposure to a carcinogen. For example, lung cancer may not occur until 30 years after a person starts smoking.
This long latency period is one of the reasons why it is difficult to determine the causes of cancer in humans. This means there is a link between the two, but there is no proof of cause and effect. More research needs to be done before we know for sure. A division of hematology and oncology, Department of Medicine, Massachusetts General Hospital, Boston, MA, USA.

Gog 240 was a practice randomized phase 3 study in evolution which concluded that chemotherapy plus bevacizumab for advanced cervical cancer significantly improves overall survival and progression-free, and the proportion of patients achieving an objective overall response compared to chemotherapy alone.
In this study, we sought to analyze the results reported by patients in gog 240. Treatment cycles were repeated every 21 days until disease progression or unacceptable toxicity, whichever comes first. For our analysis of the results reported by patients, participants were evaluated before treatment cycles 1, 2 and 5, and 6 and 9 months after the beginning of cycle 1, with thee fact-cx, makes items -GOG-neurotoxicity subscale, and worst part of the pain of the brief pain inventory. All patients who completed the basic quality of life assessments and at least one other follow-up evaluation were evaluable for the results of quality of life. This study is registered clinicaltrialsgov. Between 6 April 2009 and January 3, 2012, a total of 452 patients were included in the trial, of which 390 completed a quality of life assessment base and at least one other evaluation and were thus evaluable for quality life results.
The improvement in overall survival and progression-free survival attributed to the incorporation of bevacizumab in the treatment of advanced cervical cancer are not accompanied by a significant deterioration in health-related quality of life. Patients who responded to anti-angiogenesis therapy that maintain an acceptable quality of life might suit the progress of a new treatment with other therapies that might confer additional benefit.
