A groundbreaking study has unearthed a concerning correlation – nearly 50% of cancer cases are intricately linked to obesity.
Conducted by researchers at Lund University in Malmo, Sweden, the study spanned over four decades and observed 4.1 million participants, accurately monitoring their weight and lifestyle choices.
The findings revealed a striking connection between obesity and 32 different types of cancer, with a staggering 332,500 cancer cases identified during the course of the study.
According to the latest research, a mere five-point increase in Body Mass Index (BMI) appears to elevate the risk of these cancers by 24% among men and 12% among women.
Obesity emerges as a significant risk factor for various cancers, encompassing breast, colon, ovarian, pancreatic, and prostate cancer, among others.
The intricate relationship between obesity and cancer stems from multifaceted biological mechanisms.
Primarily, obesity fosters chronic low-grade inflammation and insulin resistance, creating an environment conducive to the proliferation of cancer cells.
Adipose tissue, or fat cells, produce hormones and cytokines that disrupt normal cellular processes, paving the way for tumour development.
Additionally, obesity often coincides with heightened levels of circulating hormones like estrogen and insulin, which can stimulate the growth of hormone-sensitive tumours such as breast and ovarian cancer.
In India, a recent study published in the Lancet revealed concerning rates of abdominal obesity in the country, with 40% of women and 12% of men affected.
Shockingly, the study found that 5–6 out of every 10 women between the ages of 30–49 are abdominally obese.
Notably, the prevalence of abdominal obesity in women is higher among older age groups, urban residents, wealthier individuals, and non-vegetarians.
Additionally, individuals practicing the Sikh religion exhibit a higher prevalence of abdominal obesity, affecting both men and women.
Alarmingly, abdominal obesity is on the rise in rural areas and is increasingly affecting lower and middle socioeconomic strata of society.
