Long term hormone therapy linked to higher breast cancer risk
Long-term use of estrogen plus progesterone and estrogen-only hormone therapy is linked with a higher risk for developing breast cancer. Researchers found this breast cancer risk was 88 percent higher.

Stress linked to breast cancer aggressiveness
Psychosocial stress could play a role in the etiology of breast cancer aggressiveness, particularly among minority populations, according to study results presented at the Fourth AACR Conference on The Science of Cancer Health Disparities, held.

Cancer mortality rates higher in men than women
Overall cancer mortality rates are higher for men than women in the United States. Men are more likely to die from cancer than women. For many cancers, men have poorer survival than women but the differences are slight, and this is due to the greater frequency of cancer diagnosis, rather than poorer survival once the cancer occurs.

Low carbohydrate, high protein diets may reduce cancer risk
Eating a low-carbohydrate, high-protein diet may reduce the risk of cancer and slow the growth of tumors already present, according to a study published in Cancer Research, a journal of the American Association for Cancer Research. The study was conducted in mice, but the scientists involved agree that the strong biological findings are definitive enough that an effect in humans can be considered.

Brisk walking could improve prostate cancer outcomes
Men with prostate cancer can improve their outcomes if they walk briskly for at least three hours a week following their diagnosis, according to a recent study in Cancer Research, a journal of the American Association for Cancer Research.

New stool test to predict colon cancer
An investigational DNA methylation test could alter the screening landscape for colorectal cancer, according to data presented at the American Association for Cancer Research special conference on Colorectal Cancer: Biology to Therapy, held here Oct. 27-30, 2010.

Higher breast density increases breast cancer risk
Researchers at Kaiser Permanente have found that patients with a very early form of breast cancer (ductal carcinoma in situ or DCIS) who have higher mammographic density may be at increased risk for subsequent breast cancer, especially in the breast opposite to the one with the initial cancer.

Obesity in colon cancer patients increases mortality
Postmenopausal women diagnosed with colon cancer may be at increased risk of death if they fail to maintain a healthy body weight before cancer diagnosis, revealed by researchers.

US cancer group AACR supports NIH stem cell research
The American Association for Cancer Research (AACR), the world's oldest and largest cancer research organization, reiterates its support for the responsible conduct of human embryonic stem cell research that, up until this week, was funded by the National Institutes of Health (NIH) and expresses concern that the recent Federal District Court injunction to block federal funding for human embryonic stem cell research is a setback for scientific discovery.

Fish oil may reduce breast cancer risk
A recent report in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, adds to the growing evidence that fish oil supplements may play a role in preventing chronic disease like breast cancer.

Few US women take tamoxifen to prevent breast cancer
Researchers with the National Cancer Institute (NCI) have found that the prevalence of tamoxifen use for the prevention of breast cancer among women without a personal history of breast cancer is very low.

Green tea may reduce lung cancer risk in smokers
Drinking green tea could modulate the effect of smoking on lung cancer. Results of this hospital-based, randomized study conducted in Taiwan were presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer, held here from Jan_11-14, 2010.

Pomegranates may prevent breast cancer growth
Eating fruit, such as pomegranates, that contain anti aromatase phytochemicals reduces the incidence of hormone-dependent breast cancer, according to results of a study published in the January issue of Cancer Prevention Research, a journal of the American Association for Cancer Research.

MRI detects breast cancer at earlier stage
Magnetic resonance imaging (MRI) coupled with mammography detects almost all cancers at an early stage, thereby reducing the incidence of advanced stage breast cancer in high-risk women.

Pistachios may reduce lung cancer risk
A diet that incorporates a daily dose of pistachios may help reduce the risk of lung and other cancers, according to data presented at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference.

Caution about mammography use among women younger than 40 years
Breast cancer screening guidelines generally recommend mammography begin at age 40. However, based on prior national research, an estimated 34 percent of non-Hispanic black women, 30 percent of non-Hispanic white women and 22 percent of Hispanic women aged 30 to 39 have reported having a mammogram.

Hops compound xanthohumol may prevent prostate cancer
The natural compound xanthohumol blocks the effects of the male hormone testosterone, therefore aiding in the prevention of prostate cancer, revealed by US researchers.

Secondhand smoke exposure increases lung cancer risk
Children exposed to secondhand cigarette smoke have an increased risk of developing lung cancer in adulthood, even if they never smoked.

Pregnancy hormone may prevent breast cancer
Researchers have found that hormones produced during pregnancy induce a protein that directly inhibits the growth of breast cancer. This protein, alpha-fetoprotein (AFP), may serve as a viable, well-tolerated agent for the treatment and prevention of breast cancer.

Less hormone therapy use in women reduced breast cancer rate
The decreased use of postmenopausal hormone therapy has played a key role in the declining rate of atypical ductal hyperplasia, a known risk factor for breast cancer, revealed by researchers.

Young women with colon cancer lived longer than men
Younger women with metastatic colorectal cancer lived longer than younger men, revealed by researchers in a new US study. However, this survival advantage disappeared with age, suggesting a benefit from estrogen or other hormones.

Social interaction or isolation affects breast cancer
Social environment can play an important role in the biology of disease, including breast cancer, and lead to significant differences in health outcome, revealed by researchers.

Women opt surgery to remove breasts, ovaries to reduce cancer risk
Many women at high risk for breast or ovarian cancer are choosing to undergo surgery as a precautionary measure to decrease their cancer risk, revealed by US researchers.

Hispanics prone to develop cancer in US
Different Hispanic population groups have higher incidence rates of certain cancers and worse cancer outcomes if they live in the United States, than they do if they live in their homelands, revealed by researchers.

Math may predict Herceptin response in breast cancer patients
Cancer researchers are turning to mathematical models to help answer important clinical questions, and a new paper in Cancer Research, a journal of the American Association for Cancer Research, illustrates how the technique may answer questions about Herceptin resistance.

Green tea slows prostate cancer progression
Men with prostate cancer who consumed the active compounds in green tea demonstrated a significant reduction in serum markers predictive of prostate cancer progression, revealed by researchers.

Charred meat may increase pancreatic cancer risk
Meat cooked at high temperatures to the point of burning and charring may increase the risk of pancreatic cancer, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009.

Wine increases survival in Non Hodgkin's lymphoma patients
Pre-diagnostic wine consumption may reduce the risk of death and relapse among non-Hodgkin's lymphoma patients, according to an epidemiology study presented at the American Association for Cancer Research 100th Annual Meeting 2009.

Walnuts may prevent breast cancer
Walnut consumption may provide the body with essential omega-3 fatty acids, antioxidants and phytosterols that reduce the risk of breast cancer, according to a study presented at the American Association for Cancer Research 100th Annual Meeting 2009.

Urine test predicts lung cancer risk in smokers
Researchers may have uncovered why lung cancer afflicts some smokers and not others, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009.
