There were 2.3 million new cases of breast cancer registered in 2020, establishing it as the world’s leading cancer. The regular exposure of breast cells to circulating ovarian sex hormones may contribute to cancer growth at all stages. A literature review was performed by downloading research articles from PubMed Central, with keywords such as breast cancer, hormone exposure in breast cancer, estrogen/progesterone exposure in breast cancer, and breast cancer risk factors. Since breast cancer is a hormone-related disease, several factors that influence hormonal conditions or are indicators of alterations in hormonal conditions have been linked with the risk for breast cancer. Likewise, an elevated risk for breast cancer has been related to reproductive history and exogenous estrogen exposure because they may amplify lifetime estrogen exposure. All these factors address the total cumulative exposure to circulating ovarian sex hormones that a female is vulnerable to in her lifetime. A healthy lifestyle, a more extended breastfeeding period, and regular physical activity may help lower one’s risk. This review summarizes the factors that increase the risk of estrogen/progesterone (hormone receptor) receptor-positive breast cancer due to overall cumulative estrogen exposure, with an understanding of estrogen biosynthesis mechanisms and estrogen receptor signaling.

In the present article, the linear and the nonlinear deformation behaviour of functionally graded （FG） spherical shell panel are examined under thermomechanical load. The temperature- dependent effective material properties of FG shell panel are evaluated using Voigt＇s micro-mechanical rule in conjunction with power-law distribution. The nonlinear mathematical model of the FG shell panel is developed based on higher-order shear deformation theory and Green-Lagrange type geometrical nonlinearity. The desired nonlinear governing equation of the FG shell panel is computed using the variational principle. The model is discretised through suitable nonlinear finite element steps and solved using direct iterative method. The convergence and the val- idation behaviour of the present numerical model are performed to show the efficacy of the model. The effect of different parameters on the nonlinear deformation behaviour of FG spherical shell panel is highlighted by solving numerous examples.
