Summary
Stable organic pollutants (SOPs) are linked to breast cancer (BC) risk, particularly in highly polluted areas. Further research is needed to assess SOPs as a risk factor for BC in general populations.
Area of Science:
- Environmental Health
- Epidemiology
- Toxicology
Background:
- Epidemiological studies show inconsistent results regarding stable organic chlorine compounds as breast cancer (BC) risk factors.
- Exposure assessment challenges and variations in study populations contribute to the ambiguity.
- Few studies have investigated stable organic pollutants (SOPs) as BC risk factors, primarily in occupational settings.
Purpose of the Study:
- To evaluate the role of stable organic pollutants (SOPs) as risk factors for breast cancer (BC).
- To identify biological, occupational, and environmental risk factors associated with BC in specific populations.
- To advocate for further ecological and epidemiological studies in industrially polluted areas.
Main Methods:
- Analytical epidemiological study utilizing a case-control approach.
- Assessment of exposure levels based on the content of stable organic substances in biological environments.
- Comparison of risk factors between case groups and control groups.
Main Results:
- Evidence suggests dioxins are a risk factor for BC in women in Seveso.
- A case-control study in Chapayevsk identified biological (family history, childlessness), occupational (work at CVZH), and environmental (pollution, consumption of local food) factors linked to BC.
- High activity of chlorine chemistry enterprises in the 1950-1960s in various Russian towns indicates potential for widespread SOP exposure.
Conclusions:
- Stable organic pollutants (SOPs) may play a role in breast cancer (BC) development, especially in areas with high dioxin pollution.
- Environmental and occupational exposures, alongside biological predispositions, are significant risk factors for BC.
- Ecological and epidemiological studies are crucial in industrial towns to determine the public health impact of SOPs on BC risk.

Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
