Background: Cancer has become a major health problem associated with high mortality worldwide, especially in developing countries. The aim of our study was to evaluate the incidence rates of different types of cancer in Sulaymaniyah from January-2006 to January-2014. The data were compared with those reported for other middle east countries. Materials and Methods: This retrospective study depended on data collected from Hiwa hospital cancer registry unit, death records and histopathology reports in all Sulaymaniyah teaching hospitals, using international classification of diseases. Results: A total of 8,031 cases were registered during the eight year period, the annual incidence rate in all age groups rose from 38 to 61.7 cases/100,000 population/year, with averages over 50 in males and 50.7 in females. The male to female ratio in all age groups were 0.98, while in the pediatric age group it was 1.33. The hematological malignancies in all age groups accounted for 20% but in the pediatric group around half of all cancer cases. Pediatric cancers were occluding 7% of total cancers with rates of 10.3 in boys and 8.7 in girls. The commonest malignancies by primary site were leukemia, lymphoma, brain, kidney and bone. In males in all age groups they were lung, leukaemia, lymphoma, colorectal, prostate, bladder, brain, stomach, carcinoma of unknown primary (CUP) and skin, while in females they were breast, leukaemia, lymphoma, colorectal, ovary, lung, brain, CUP, and stomach. Most cancers were increased with increasing age except breast cancer where decrease was noted in older ages. High mortality rates were found with leukemia, lung, lymphoma, colorectal, breast and stomach cancers. Conclusions: We here found an increase in annual cancer incidence rates across the period of study, because of increase of cancer with age and higher rates of hematological malignancies. Our study is valuable for Kurdistan and Iraq because it provides more accurate data about the exact patterns of cancer and mortality in our region.

More than one million new patients suffer from breast cancer annually in the world. In developed countries, breast cancer is the most common malignancy diagnosed among women, and in developing regions, it often ranks second to cervical cancer. This study aimed to investigate the relationship between incidence of breast cancer and reproductive factors in North-West of Iran. This retrospective analytical control-case study was conducted with 235 breast cancer patients and 235 women in the control group. Data collection tools included a set of questions with interviews and patient medical records. Data were analyzed using statistical tests: t-test, Chi-square, Fisher, and Pearson correlation coefficient. Significantly increased risks were associated between breast cancer and older age at first pregnancy, age at menopause and history of contraceptive use. A trend for decreasing risk were observed with increasing parity. Findings of this study showed no association between breast cancer and age at menarche. The study results suggested that physiological and reproductive factors may play important roles in the development breast cancer among Iranian women.

Breast cancer is one of the major threats to female health, and its incidence is rapidly increasing in many countries. Currently, breast cancer is treated with surgery, followed by chemotherapy or radiation therapy, or both. However, a substantial proportion of breast cancer patients might have a risk for local relapse that leads to recurrence of their disease and/or metastatic breast cancer. Therefore searching for new and potential strategies for breast cancer treatment remains necessary. Immunotherapy is an attractive and promising approach that can exploit the ability of the immune system to identify and destroy tumors and thus prevent recurrence and metastatic lesions. The most promising and attractive approach of immunotherapeutic research in cancer is the blockade of immune checkpoints. In this review, we discuss the potential of certain inhibitors of immune checkpoints, such as antibodies targeting cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed death 1 (PD-1) and lymphocyte activation gene-3 (LAG-3), in breast cancer therapeutics. Immune checkpoint inhibitors may represent future standards of care for breast cancer as monotherapy or combined with standard therapies.

Background: Cancer is a major public health problem both in our country and worldwide due to its disease burden, fatality and tendency for increased incidence. In Turkey, breast cancer ranks first with an incidence of 41.6% and cervical cancer is the tenth most common cancer with an incidence of 4.4%. Objectives and Design: This descriptive, cross-sectional study was conducted with 240 women aged from 15 to 65 years admitted to a gynecology-obstetrics outpatient clinic of a private hospital in Gaziantep. Study data were collected by the investigators through a 36-item questionnaire form which was generated using information gathered from similar surveys in the literature. Results: It was determined that 34.6% of women were high-school graduates, and 64.2% had a medium income level. The majority (79.2%) stated that they never performed BSE and 49.5% of them said that they did not know how to do it. Some 79.2% did not know what a Pap smear was and 73.3% had not experienced a smear test ever. Conclusions: In this study, we found that most of the women had insufficient knowledge of breast and cervical cancer, while knowledge and practices increased with the education level. Based on these findings, we suggest that there is a need for planning, implementation and assessment of health policies and healthcare services at the national and regional level and we believe that nurses working in the field of protective health services should develop educational programmes for women with a primary focus on cancer in order to increase awareness among the female population in Turkey.

Background: Breast cancer is the most frequent malignant disease amongst young women. If we review local data in Pakistan then breast cancer represents approximately a third of all cancers in females. The age standardized incidence rate (ASR) world per 100,000 is 53.8 and crude incidence rate is 30.9. We have observed during our surgical pathology practice and it is also reported by other Asian studies that breast carcinoma is amongst the leading malignancies in the region and the patients are at least a decade younger than counterparts in developed nations. Age is an important issue in effective screening, diagnosis and management of breast cancer, especially in this geographical region where late presentation and poor prognosis are a hallmark of the disease. Objective: The aim of this study is to determine the frequency of malignant breast lesions in symptomatic young females presenting with breast lumps. Materials and Methods: This is a retrospective study conducted at the Pathology Department, Liaquat National Hospital and Medical College, Karachi. Descriptive and pathology data of malignant breast tumors 1st January 2004 to 31st December 2009 were reviewed, using the departmental archived data. It included both male and female patients up to the age of 25 years. Results: A total of 714 surgical specimens from/of symptomatic breast lesions were received at the pathology department of Liaquat National Medical, in the five years study period, in young females. There were 575 (80%) benign, 119 (16%) inflammatory and 20 (2.8%) malignant lumps. Conclusions: The obtained data for females only up to 25 years of age suggest a massive burden which requires urgent attention. Early assessment of lesions is essential in order to avoid mortality from malignancies.

Breast cancer is the first or second leading cancer among females across the globe. A large number of studies have been conducted to assess any relationship between vitamin D receptor (VDR) gene polymorphisms and breast cancer development. Epidemiological studies have indicated that ethnic traits exhibited by a group of people with a common ancestry and culture, alter the link between VDR gene and breast cancer. It has been hypothesized that VDR polymorphisms have the capacity to impact both on incidence of breast cancer occurrence and to predict its outcome. A survey was here conducted to assess and compare the impact of vitamin D receptor gene polymorphisms Fok1, Bsm1, Taq1, Apa1 and poly (A) on development of breast cancer. Information was obtained from electronic databases including PubMed and Google Scholar for articles published during the period from 1996 to 2015. This search was achieved by using the terms "genetics", "breast cancer", "VDR gene", "polymorphisms". However, due to inconsistent results, no conclusive statements could be presented about the significance of the VDR genotype as far as the development of breast carcinoma is concerned.

Breast cancer is one of among all cancers with increased incidence, high mortality rate, and high economic and social costs. The the most common type of cancer among females worldwide, breast cancer is actually the uncontrolled proliferation of cells which attain malignancy. Recently it has shown that breast cancer contributes 11% among all types of cancer diagnosed globally on an annual basis and it is one of the leading causes of death among women. The human epidermal growth factor receptor 2 (HER-2) is a receptor tyrosine-protein kinase erbB-2 normally involved in the proliferation and division of breast cells. In some abnormal cases the HER2 gene does not work correctly and makes too many copies of itself. HER2-positive (HER2+) breast cancers constitute an aggressive type of breast cancer and tend to grow faster and are more likely to spread. However, therapies that specifically target HER2, such as Herceptin$^{(R)}$ (traztuzumab), are very effective. HER2 targeted therapies, has significantly improved the therapeutic outcome for patients with HER2 positive breast cancer.

Breast cancer is common in West and Incidence of breast cancer has increased in Korea. According as conventional western medical treatment, breast cancer patient received MRM(modified radical mastectomy) and anti cancer chemotherapy. In this case report, We introduce a case of breast cancer patient who showed lung metastasis(metastatec adenocarcinoma) after MRM(modified radical mastectomy) 4 years before the diagnosis of relapse. After lung metastasis of breast cancer, the patient received 4th chemotherapy and refused to get more conventional western medical treatment including chemotherapy. After 24 month of traditional oriental medical treatment using allegen removed Rhus Verniciflua Stokes(ARV), however, the size of cancer mass decreased and the patient showed improved condition. Further case study will be needed in order to determine the effect of ARV on breast cancer patient.

Breast cancer is the top cancer in women worldwide and its incidence is increasing, particularly in developing countries. In the United Arab Emirates (UAE), many cases are first diagnosed in later stages and at younger age compared to those seen in developed countries. Early detection in order to improve breast cancer outcome and survival remains the cornerstone of breast cancer control. Performance of breast self examination is one of the important steps for identifying breast disease at an early stage, by the woman herself. No information has hitherto been available about the frequency of this practice among female university students in UAE or about their breast cancer risk perception and therefore the present study was conducted in Ajman. It was found that 22.7% of the participants practiced BSE but only 3% of them practiced BSE monthly. Marital status but not age as significantly associated with age likelihood. The most frequent reported barriers for BSE were lack of knowledge, considering oneself not at risk and the absence of doctor advice. These factors need to be taken into account in intervention efforts.

Osteopontin (OPN) is an integrin-binding protein, believed to be involved in a variety of physiological cellular functions. The physiology of OPN is best documented in the bone where this secreted adhesive glycoprotein appears to be involved in osteoblast differentiation and bone formation. In our study, we used semi-quantitative RT-PCR of osteopontin in calcification tissue of breast to detect breast cancer metastasis. The obtained data indicate that the expression of osteopontin is related to calcification tissue of breast, and possibly with the incidence of breast cancer. The expression strength of OPN by RT-PCR detection was related to the degree of malignancy of breast lesions, suggesting a close relationship between OPN and breast calcification tissue. The results revealed that expression of OPN mRNA is related to calcification of breast cancer tissue and to the development of breast cancer. Determination of OPN mRNA expression can be expected to be a guide to clinical therapy and prediction of the prognosis of breast cancer patients.
