“…Although the trend of breast cancer incidence across most of the Asian countries is increasing, heterogeneity among countries is particularly apparent due to different health policies, regional behaviors, and genetic and lifestyle variety [6]. While the incidence rate of breast cancer has doubled or more in Korea, Singapore, Hong Kong and Japan, besides socioeconomic advancement [10] in the last decades [6,11], a substantial increase was found in China (2.96% per year) [12], Thailand [13] and Taiwan [3]; also, a gradual increase was reported in Sri Lanka [14], Pakistan [15], India [16], and…”

Breast cancer among Asian countries is the second cause of cancer death and remains as a challenging issue in woman health as 39% of all new cases of breast cancer have been diagnosed in Asia. The current study was devoted to recognize different patterns of breast cancer incidence rate among Asian countries. Information about the incidence rates of female breast cancer within 1990-2016 years was extracted from Gapminder web site and growth mixture model was developed to describe the growth patterns and provide a set of tools to investigate the individual differences in change. Our findings suggest an overall increasing trend throughout the continent, but individual trajectories show different behaviors among countries. Bayesian information creation showed that 3-cluster model was the best. Cluster one countries including: Bangladesh, Israel, Kyrgyz republic, Maldives, Nepal, North Korea, Tajikistan and Timor-Leste, the slope of -0.13 suggests a slight negative trend for the incidence rate of breast cancer. 17 countries including: Armenia, Bahrain, Brunei, Cyprus, Iraq, Japan, Jordan, Kazakhstan, Kuwait, Lebanon, Malaysia, Pakistan, Philippines, Qatar, Singapore, South Korea, United Arab Emirate which belongs to cluster 2, had not only a high intercept that means higher amounts of incidence rate in 1990 year, but also a slope of 0.96, indicating a sharp increase trajectory. Also slope of 0.38 showed a slow increase in the incidence rate of breast cancer over time for another 21 countries. In conclusion, increase of breast cancer incidence among cluster 2 countries is tremendous therefore effective strategies for prevention are urgently needed.

“…Breast cancer was ranked as the second leading cause of cancer deaths after lung cancer in Sri Lanka [27]. Over the past decade (from 2001 to 2010) a 1.4-fold rise in the incidence of breast cancer was recorded in an island-wide study indicating a rising disease burden [28].…”

“…Ÿ A place for opportunistic screening Currently, there are opportunistic mammography screening facilities in a limited number of centres in Sri Lanka which are mostly distributed in the private sector. NCCP guidelines recommend screening women aged between 50 to 69 years [29] which is in concurrence with the current rising breast cancer incidence seen in the women over 50 years [28]. How well these guidelines are reached and practised by the individual centres remain unexplored.…”

Population-based mammography screening programmes were launched by developed countries in the latter half of the twentieth century based on the promising evidence on mortality benefits reported by the earliest randomised control trials (RCTs). It was widely accepted that screening mammography significantly reduced breast cancer mortality in women invited for screening. However, since the first RCT in the 1960s, varying evidence has been tabled by many researchers, sometimes alarming the public, drawing attention to the harms of screening mammography, mainly identified as overdiagnosis and false positives. While overtreatment is recognised as a consequence of over diagnosis, a relatively newer set of harms categorized under psychological distress have been highlighted as resultant from false positive screening tests. Currently, the magnitude of the harms of screening mammography remains uncertain. The most turbulent reviews on breast screening, however, were the queries into the well and long believed mortality benefits of mammography screening first tabled in the 1970s by the Canadian national breast screening study. A Cochrane review by Gøtzsche and Jørgensen further added to the negative attributes of mammography screening as they concluded that the actual current mortality benefits are nonsignificant and smaller than that claimed by many RCTs which were poorly randomised. Although heavily criticized, sparks ignited by these reports have led many countries worldwide to conduct their panel discussions on evidence on population screening mammography. While many countries have decided to continue their programmes understanding the harms involved, Switzerland in this light has discontinued their population-based mammography screening programme. The debate continues; currently while not overlooking the mortality benefits of mammography, it is also understood that the mortality benefits are not solely due to mammography but are also contributed by other factors such as advancement in Correspondence: U.A.

“…The management of breast cancer, the commonest cancer worldwide in women, has evolved during the last several decades where breast conservative treatment with systemic therapy has replaced radical surgery, improving quality of life and overall survival [1,2]. However, this has resulted in an increased incidence of radiation-induced soft tissue sarcoma of the breast [3].…”

Radiation-induced sarcoma of the breast is an iatrogenic malignancy that occurs secondary to radiotherapy, which is most commonly given following breast conservation surgery. It has an incidence of 3.2 per 1,000 patients at 15 years and is associated with a poor prognosis. We report a 62-year-old female with a history of bilateral breast conservation surgery and radiotherapy 5 years ago presenting with bilateral angiosarcoma. This case report highlights the importance of considering radiation-induced angiosarcoma of the breast as a differential diagnosis in a patient with recurrent breast neoplasms. The challenges in the management with recent evidence on new treatment modalities are discussed.
