Detection and analysis of microplastics in tissues and blood of human cervical cancer patients
AI summary Read the abstract
In the first study of its kind, researchers detected 13 types of microplastics in the blood, tumor tissue, and surrounding tissue of cervical cancer patients using Raman spectroscopy. Microplastic levels were higher in cancerous tissue than in nearby healthy tissue, and factors like age, BMI, and bottled water consumption correlated with greater microplastic abundance, suggesting a possible link between plastic exposure and reproductive health.
Microplastics (MPs) can enter the reproductive system and can be potentially harmful to human reproductive health. In this study, 13 types of microplastics (MPs) were identified in patient blood, cancer samples, and paracarcinoma samples using Raman spectroscopy, with polyethylene, polypropylene and polyethylene-co-polypropylene being the most abundant polymer types. Futher, cotton was also found in our study. The diversity and abundance of MPs were higher in blood samples than in cancerous tissues, and there was a significant positive correlation between diversity (p < 0.05). Furthermore, the diversity and abundance of MPs in cancerous tissues were higher than in paracancerous tissues. The dimensional sizes of MPs in these samples were also very similar, with the majority of detected MPs being smaller in size. Correlation analysis showed that patient's age correlated with the abundance of MPs in blood samples, body mass index (BMI) correlated with the abundance of MPs in cancerous tissues. Notably, the frequency with which patients consume bottled water and beverages may also increase the abundance of MPs. This study identifies for the first time the presence of MPs and cotton in cancerous and paracancerous tissues of human cervical cancer patients. This provides new ideas and basic data to study the risk relationship between MP exposure and human health.

Microplastic changes during the development of cervical cancer and its effects on the metabolomic profiles of cancer tissues
AI summary Read the abstract
Researchers found microplastics in cervical cancer tissue, with polyethylene and polypropylene being the most common types, and levels increased as the cancer progressed to more advanced stages. The microplastics appeared to alter the chemical environment within the cancer tissue, suggesting they may play a role in how cervical cancer develops, though more research is needed to confirm a causal link.
Identification and Characterization of Microplastics in Human Cervicovaginal Lavage Fluids Using Raman Spectroscopy: A Preliminary Study
AI summary Read the abstract
In a first-of-its-kind study, researchers detected microplastic particles in the cervicovaginal fluid of all 10 women tested, with polypropylene and polystyrene being the most common types. One participant who regularly used a menstrual cup had significantly more microplastic particles than others. The findings confirm that the female reproductive tract is exposed to microplastics, raising questions about potential effects on reproductive health.
Analytical Trends and Pathogenesis of Microplastics in Human Cancer Tissues: A Toxicology Mini-review
AI summary Read the abstract
This toxicology mini-review synthesizes evidence that microplastics have been identified in human cancer tissues — including colorectal, prostate, lung, gastric, and cervical tumors — using analytical tools like µ-FTIR and Raman spectroscopy. The findings suggest microplastics may preferentially accumulate in cancerous tissues and could play a role in tumor development and progression.
Microplastics detected in three types of female reproductive organs using micro-Raman spectroscopy
AI summary Read the abstract
Researchers detected microplastics in tissue samples from three types of female reproductive organs — uterine tissue with adenomyosis, ovarian cysts, and fallopian tubes — collected from 60 women. Polyethylene and polypropylene were the most common types found, with most particles smaller than 20 micrometers. This study provides direct evidence that microplastics accumulate in human reproductive tissues, though more research is needed to determine whether they contribute to reproductive diseases.
Identification and analysis of microplastics in human penile cancer tissues
AI summary Read the abstract
Researchers found microplastics in tissue samples from patients with penile cancer, with the most common types being polyethylene, polypropylene, and PVC. Cancerous tissue contained significantly more microplastics and a greater variety of plastic types than nearby healthy tissue, suggesting a possible link between microplastic accumulation and cancer development that needs further investigation.
