Cancers affecting the female uterus, fallopian tubes, ovaries, vagina, and vulva are considered gynaecological cancers. Therefore, the risk of gynaecological cancer exists in all women. There is mounting evidence linking obesity to gynaecological cancers when lifestyle risk factors for these diseases are examined. Since 1975 until 2016, when WHO designated obesity a pandemic non-communicable disease, the prevalence of obesity in women has tripled. Despite the availability of better treatment options, higher BMI values were significantly associated with a rise in the death rates from gynaecological cancers. Inflammatory mediators have been found to promote illness and change cancer biology in fat tissue. Metabolic syndrome, which has been linked to malignancies, particularly uterine cancer, includes obesity along with high blood pressure, high blood sugar levels, and low levels of good cholesterol. Another risk factor that raises the likelihood of these cancers is smoking. Smoking impairs the immune system, which makes one more vulnerable to cervicitis infected with the HPV (human papilloma virus) due to the by-product of tobacco serving as a chemical carcinogen. Smoking and high-risk sexual behaviours (HRSB) increase the risk of gynaecological malignancies. Because they are higher in nutrients and fibre than other foods, fruits and vegetables help people feel full on fewer calories. This condition can be avoided by changing eating habits to incorporate them every day. Refined food products should be avoided since they quickly raise blood glucose levels and increase a person's risk of developing diabetes. Reduce your intake of processed foods that are high in calories and sugar, such as sugary drinks, cakes, cookies, and ice cream, by avoiding them. An increase in general health and a decrease in obesity rates have been linked to eating a plant-based diet. The ideal exercise for maintaining a healthy weight with a BMI under 30 is brisk walking. A healthy eight hours of sleep lowers the risk of developing obesity. It is recommended to have an anti-HPV vaccine and undergo routine Pap testing for cervical cancer. To avoid STDs and use birth control pills, barrier contraception is indicated. Regular gynaecological exams are advised, especially if there is a family history of close relatives developing gynaecological cancers.
