Fewer women in the United States are dying from breast cancer, but disparities in death rates still exist according to a new study.

Among unmarried cancer patients, those who are separated at the time of diagnosis do not live as long as widowed, divorced, and never married patients. That is the conclusion of a new study to be published in the November 1, 2009 issue of Cancer, a peer-reviewed journal of the American Cancer Society. The authors of the study say its results suggest that the stress associated with marital separation may compromise an individual's immune system and lead to a greater susceptibility to cancer.

A new finding reveals that African-American patients with breast, ovarian, and prostate cancer tend to die earlier than patients of other races with these cancers, even when they receive identical medical treatment and when socioeconomic factors are controlled for.

60 percent of cancer patients are older, but they are 'systematically excluded' from clinical trials

The odds of surviving cancer of the pancreas increase dramatically for patients whose tumors are smallest, according to a new study by researchers at Saint Louis University and the M.D. Anderson Cancer Center in Houston – the first study to specifically evaluate the link between tumor size and survival rates for one of the most common and deadly cancers.

Receiving treatment for non-cancer health issues while being treated by specialists for cancer improves cancer survival rates according to a study published in the December 20 issue of the Journal of Clinical Oncology.

One of the deadliest forms of cancer appears to carry a specific weakness.

Having someone to drive you to cancer treatments or make sure you are eating may be even more important than tumor size or other medical factors in predicting cancer survival.

Rudy Giuliani defends the survival rates he quotes when talking about his prostate cancer.

A patient’s positive or negative emotional state has no direct or indirect effect on cancer survival or disease progression, according to a large scale new study. Published in the December 1, 2007 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study found that emotional well-being was not an independent factor affecting the prognosis of head and neck cancers.

For the 10 million Americans who are living with cancer or have survived it, one factor may be most indispensable for keeping their spirits intact: communication. In recognition of this, the National Cancer Institute plans to issue a special report by November 1, co-authored by a University of Rochester physician, stating that effective communication is truly essential to good cancer care and deserves more research.

Variations in a gene that influences the innate immune system—the part of the immune system that provides short-term protection against infection—may be associated with lung cancer survival.
