This study is examining the relationship between ingested arsenic and bladder cancer in two areas of California where a large percentage of the population was exposed to drinking water containing arsenic at low to moderate levels.
Water supplies in many parts of the world contain naturally occurring arsenic. Previous studies have shown that arsenic at high doses can cause cancer of the bladder. The risk at lower doses is unknown. This study is examining the relationship between ingested arsenic and bladder cancer in central Nevada and Kings County, California, two areas where a large percentage of the population was exposed to drinking water containing arsenic at low to moderate levels. Approximately 200 people with bladder cancer and 400 people without bladder cancer will be included. Subjects are interviewed by telephone about past residences, occupations, diet, drinking water consumption, and other lifestyle factors. Arsenic measurements in well water have been collected from the appropriate state agencies and are being matched with residences and drinking water consumption rates to estimate lifetime arsenic exposures for each subject. People with bladder cancer will then be compared to those without to see if people with cancer were more likely to have lived in areas with arsenic in their drinking water.

To monitor the quality of bladder cancer care, the Swedish National Register of Urinary Bladder Cancer (SNRUBC) was initiated in 1997. During 2015, in order to study trends in incidence, effects of tr...
To evaluate the diagnostic accuracy of the Xpert Bladder Cancer (BC) Monitor, compared to cystoscopy and cytology in the oncological follow-up of non-muscle invasive bladder cancer (NMIBC).
Molecular markers of clinical outcome may aid in designing targeted treatments for bladder cancer. However, only a few bladder cancer biomarkers have been examined as therapeutic targets.
Bladder cancer is a common disease with a stable incidence for the past few decades despite advancements in molecular and genetic determinants of cancer development and progression. Cystoscopy remains...
Tetrandrine and Fangchinoline (Fcn) are two natural products that are found in Stephania tetrandra. Tetrandrine is a known anti-bladder cancer compound, but the effects of Fcn on bladder cancer have b...
Tumors or cancer of the URINARY BLADDER.
A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.
Involuntary discharge of URINE as a result of physical activities that increase abdominal pressure on the URINARY BLADDER without detrusor contraction or overdistended bladder. The subtypes are classified by the degree of leakage, descent and opening of the bladder neck and URETHRA without bladder contraction, and sphincter deficiency.
An abnormal passage in the URINARY BLADDER or between the bladder and any surrounding organ.
Blocked urine flow through the bladder neck, the narrow internal urethral opening at the base of the URINARY BLADDER. Narrowing or strictures of the URETHRA can be congenital or acquired. It is often observed in males with enlarged PROSTATE glands.

Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
Non-invasive bladder cancer is a cancer that is only in the inner lining of the bladder. Invasive bladder cancer is cancer that has spread into the deeper walls of the bladder. When the cancer has spread outside the bladder to other parts of the body, th...
