A study of 59,070 cancers newly diagnosed during the years 1978 through 1982 among black and white males and females was conducted to assess variations in age-adjusted incidence rates across four marital categories, single, married, divorced, and widowed. Population data were obtained from the 1980 Census. Distinct patterns of cancer incidence by marital status were observed for black and white...

INTRODUCTION Breast cancer is the second leading cause of cancer death in women worldwide and the third most common cancer in India. Various studies have reported that chemotherapy reduces the antioxidant status in patients with cancer. A diet rich in omega-3 fatty acids has been shown to offer protection against breast cancer through various mechanisms. However, there are no reports suggesting...

Alcohol consumption is an established risk factor for breast cancer. Whether associations vary by specific tumor characteristics independent of other characteristics is unclear. We evaluated the association between alcohol consumption and breast cancer risk in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial cohort (54,562 women aged 55-74 years recruited at 10 US screening ce...

Estrogen receptor (ER) status is an important biomarker in defining subtypes of breast cancer differing in antihormonal therapy response, risk factors and prognosis. However, little is known about association of ER status with various risk factors in the developing world. Our case-control study done in Kerala, India looked at the associations of ER status and risk factors of breast cancer. From...

Sun exposure has been associated with lower death rates for pancreatic cancer in ecological studies. Skin exposure to solar ultraviolet B radiation induces cutaneous production of precursors to 25-hydroxy (OH) vitamin D (D) and is considered the primary contributor to vitamin D status in most populations. Pancreatic islet and duct cells express 25-(OH) D(3)-1alpha-hydroxylase that generates the...

In the 1996 Nutritional Prevention of Cancer (NPC) trial, selenium supplementation was associated with a reduced risk of prostate cancer. This relationship was further studied in two large well‐ designed clinical trials, but no significant associations were found. However, the study populations in both of these trials had a moderate to high selenium status while the NPC trial population had a l...

BACKGROUND Very few studies have examined the association between financial status and the quality of life (QOL) of patients with specific cancers. Ovarian cancer survivors frequently suffer repeat recurrence and subsequent treatment and, as a result, a significant added financial burden. Financial burdens disproportionally affect patients of low income. This study examines the association betw...

BACKGROUND/AIM The aim of our study was to check how MGMT methylation status together with known factors influenced the risk of colon cancer development. MATERIALS AND METHODS We examined patients with colon polyps. Information concerning gender, age, lifestyle, diet, anthropometry and medical information, including cancer and family history of cancer, was analyzed. Polymorphism variety of MG...
