Background: A possible correlation between hormonal stimulation during treatment of infertility and the risk of cancer of the breast, the ovaries, the cervix or the uterus has been investigated in a number of epidemiological studies. The purpose of this article is to review the relevant literature and summarise the findings. KNOWLEDGE BASE: This review article is based on literature searches in the databases MEDLINE, Cochrane and EMBASE.
Results: No studies showed a specific general correlation between hormonal ovulatory stimulation used as pre-treatment to assisted fertilisation and an increased risk of cancer of the breast, the ovaries, the cervix or the uterus. Most studies detected no increased risk. Some studies, however, showed an increased risk of cancer among certain sub-groups, such as women who have received repeated treatment with clomiphene citrate.
Interpretation: On the basis of the studies reviewed, the conclusions are ambiguous. It is therefore necessary to monitor the long-term effects of infertility treatment on women's health. Further good-quality large-scale population studies are necessary, with longer follow-up periods and better adjustment for confounding factors.

Cancer Foundation of India, Kolkata, West Bengal, India.
Objective: The case-control study aims to identify the potential risk and protective factors contributing to breast cancer risk in the high-incidence Aizawl population and the low-incidence Agartala population, using age-specific prevalence data of established reproductive factors and body mass index (BMI) among healthy women.
Methods: A risk profile survey was conducted on asymptomatic women aged 30-64 in Aizawl and Agartala towns. Data was analysed using SPSS software.

Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama, Japan.
Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer.
Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy).
Analyzing Secondary Cancer Risk: A Machine Learning Approach.

January 2025
Department of Physics, Faculty of Sciences, Arak University, Arak, Iran.
Objective: Addressing the rising cancer rates through timely diagnosis and treatment is crucial. Additionally, cancer survivors need to understand the potential risk of developing secondary cancer (SC), which can be influenced by several factors including treatment modalities, lifestyle choices, and habits such as smoking and alcohol consumption. This study aims to establish a novel relationship using linear regression models between dose and the risk of SC, comparing different prediction methods for lung, colon, and breast cancer.
