Abstract Bladder cancer is among the top ten most common cancer types in the world, with approximately 550,000 new cases annually. The highest burden of bladder cancer is currently falling on most developed communities across the globe. But with an anticipated shift in world demographics with growing and aging populations mainly on the African continent, and important shifts in exposure to different risk factors across the world, this is likely to change over the next decades. In this review, we provide an overview of the current incidence, mortality, prevalence, survival, risk factors and costs of bladder cancer worldwide.

Bladder cancer (BC) is the sixth most common cancer in the world. An increase in the incidence and recurrence of BC has led to massive pressure on health care systems. Studies have shown that the geographical and ethical distributions of BC are variable in different parts of the world. However, most studies have focused more on clinical challenges and treatment strategies in BC management. Due to the limited number of studies conducted on the incidence rate, mortality and risk factors of BC worldwide, it is necessary to carry out studies in these areas. Therefore, the aim of this study was to determine the global incidence rate, mortality rate and risk factors for BC.

The article is devoted to breast cancer, a common cancer among women around the world. The level of awareness of applicants and employees of the Kharkov State Academy of Physical Culture regarding risk factors and clinical features of breast cancer, as well as self-examination procedures was analyzed. It has been proven that the formation of a culture of prevention of breast cancer through self-observation and self-examination of young Ukrainian women can save human lives, since raising public awareness and gaining practical knowledge will certainly change the fate of many people.

Matrix metalloproteinases (MMPs) play an important role in many physiological and pathological processes, including neoplastic processes. They belong to a group of enzymes called endopeptidases and have the ability to hydrolyze all proteins in the extracellular matrix (ECM). They are produced in most connective tissue cells, macrophages, leukocytes, endothelial cells, microglial cells and in cancer cells. Neoplastic diseases are one of the main causes of death in Poland and in the world, therefore learning about the process of carcinogenesis seems to be particularly important. The process of carcinogenesis is currently widely studied and MMPs play one of the key roles in the development of cancer. They do this by regulating local tumor growth, stromal invasion, stimulating angiogenesis and metastasis formation. Bladder cancer is the 7th most common cancer in the male population and the 11th most common cancer in the world. In bladder cancer, most studies have been devoted to MMP-2 and MMP-9, that are enzymes responsible for the degradation of type IV collagen in the first place, which through the destruction of basement membranes and ECM, play an essential role in the tumor invasion process. Since bladder cancer is characterized by the ability to relapse, from the point of view of clinical practice it seems particularly important to develop a marker of early bladder tumor recurrence. MMPs detected in the urine and serum of patients with bladder cancer are potential factors that could play such a role.

The present study aimed to provide information about the common cancer types and respective predisposing risk factors among the Bangladeshi cancer patients from different cancer hospitals located in Dhaka city. A survey is conducted to establish a relationship between common cancer types and predisposing risk factors. A nationwide representative sample of 610 Bangladeshi cancer patients were asked about their medical history, life-style, eating habit and genetic risk factors in relation to cancer prevention, as a part of omnibus survey. Interviews were conducted with 610 subjects (339 men and 271 women). Among the male, the leading cancers were lung (76 patients), followed by mouth and oropharynx (66 patients), stomach (41 patients) etc. Among the female, breast cancer (64 patients) ranked the topmost position, followed by cervix (48 patients), ovary (37 patients), mouth and oropharynx (34 patients). Among 11 risk factors among men candidates, the attributable fraction of cancer causing by tobacco smoking was considered highest (68.14%), followed by betel leaf (67.55%). For most risk factors, attributable fraction responses were higher in women than in men. 14 risk factors among women cancer patients, the attributable fraction of cancer causing by viral and bacterial diseases (39.10%) was highest, followed by obesity (37.10%) and then chronic disease (37.03%) excluding food habit. Our results suggest that awareness of the attributable fraction of cancer causes in the Bangladeshi cancer patient tends to be dominated by tobacco smoking, food habit, cancer causing infection, men and women hygiene, and reproductive history among females rather than genetic factors.DOI: http://dx.doi.org/10.3329/sjps.v4i2.10439  S.

Lebanon has one of the highest estimated age-standardized incidence rate (ASR(w)) of bladder cancer (BC) worldwide. The aim of this study is to analyze the incidence rates for BC in Lebanon over a period of 7 years and to compare them to the rates in other countries. Data were obtained from the Lebanese National Cancer Registry for the currently available years 2005 to 2011. The calculated ASR(w) and age-specific rates were expressed as per 100 000 population. From 2005 to 2011, BC has been ranked as the third most common cancer in Lebanon. It accounted for 9.0% of all newly diagnosed cancer cases excluding nonmelanoma skin cancer. It ranked second in males and ninth in females. The average ASR(w) over this period was 31.2 in men and 7.3 in women. These incidence rates are among the highest worldwide across all age groups in both sexes. This study shows that the incidence of BC in Lebanon is high and it is among the highest worldwide. It is important to reduce the risk of BC through tobacco control and by decreasing exposure to avoidable environmental and occupational risk factors.
