Notably, HPMs can damage brain structures, particularly the hippocampus, causing oxidative stress and DNA damage, which in turn contribute to cognitive impairment. The immune system is subject to dual effects from HPMs, exhibiting both stimulatory and suppressive immune responses contingent on the specifics of exposure details. In the reproductive system, HPMs are observe to diminish male fertility by interfering with spermatogenesis and semen quality, although antioxidants may mitigate these effects. Furthermore, HPMs may exacerbate skin conditions, such as atopic dermatitis, and potentially accelerate the onset of skin cancer. With regard to cardiovascular health, these effects are usually transient, mainly affecting blood pressure and heart rate, but ultimately not impairing them.

Malignant tumours can develop quickly, pass through neighboring tissues, and extend to further brain regions or the central nervous system. In contrast, healthy tumors typically develop slowly and do not invade surrounding tissues. Individuals frequently struggle with sensory abnormalities, motor deficiencies affecting coordination, and cognitive impairments affecting memory and focus. In this research, Utilizing Phase-aware Composite Deep Neural Network Optimized with Coati Optimized Algorithm for Brain Tumor Identification Based on Magnetic resonance imaging (PACDNN-COA-BTI-MRI) is proposed. First, input images are taken from the brain tumour Dataset. To execute this, the input image is pre-processed using Multivariate Fast Iterative Filtering (MFIF) and it reduces the occurrence of over-fitting from the collected dataset; then feature extraction using Self-Supervised Nonlinear Transform (SSNT) to extract essential features like model, shape, and intensity. Then, the proposed PACDNN-COA-BTI-MRI is implemented in Matlab and the performance metrics Recall, Accuracy, F1-Score, Precision Specificity and ROC are analysed.
